Arriving every day. And now one local rescue center is desperately appealing to the public for help. John ramos has the story. Reporter this public open house at the International Bird rescue in fairfield almost didnt happen, but they decided to go through with it anyway, because they thought it was important for the public to understand the crisis theyre dealing with. The International Bird rescue center is accustomed to dealing with injured or sick birds, but what began slowly in april has suddenly become overwhelming. We were all going back and forth like is this a thing, is it not a thing. And then over the last four, five days things just kind of cratered. For the first time in ten year, this is the most pelicans ive seen here. Reporter brown pelicans are the birds you see at the beach skimming over to water in formation like a squadron of fighter plane, but lately theyve been found wandering in unusual places, unable to fly away from people. One bird that we have in care right now came in from santa cruz. It had tried to walk into a bar right near the boardwalk. So these birds are disoriented. Reporter theyre not sick, theyre starving. For some reason that remains a mystery, the birds cannot find the fish they need to survive. They eat the same diet as other birds, but it is only the pelicans that are being brought in by the dozens. One of the things that well be relying on is the ocean scientists and avian folks to figure out why this fishing stock is eluding them. Some of them are coming in less than half of the body weight that theyre supposed to be. So imagine a human going through that, you know, youre supposed to weigh 150 pounds, youre coming in at 75 pounds, youre going to be having some severe problems. Reporter the center currently has 120 pelicans and is expecting another 30 to 40 in a few days. As a result, the rescue center is facing a crisis of its own. The birds respond well to the food and vitamins theyre getting, but they cant be released into the wild until there is a food supply for them. Its putting a major drain on the centers finances. And right now our were going through 500 pounds of fish a day. Thats 1,000 a day. So you can, you know, start to multiply that out. Reporter so theyre asking for help. Donations to help pay for food and volunteers to help care for so many patients. I mean, especially for crises as this, we need as many hands on deck as we can get. And volunteers are the backbone of this organization. Reporter no one knows for sure why this is happening or when it might end. Pelicans burn a lot of calories and can die within days with no food, so the fear is for each of the birds that have been captured and saved m more have already perished in the wild. The center says any pelican found acting strangely or listless should be reported immediately to local animal control. And if you are interested in donating or volunteering, theres a link to the center on our website. Its at kpix. Com. Meanwhile, in the north bay, roanoke park police say that they are investigating a burglary which led to the discovery of a bird fighting ring. Police say that they found these blades at the property designed to go on to the beaks of bird fights. Police say it all started in march with an investigation into a burglary at a storage facility. Evidence there led to a property on stony point road. Thats where they found 1,000 game birds raised for fighting along with other malnourished animals. Two people were arrested. Sonoma county Animal Service says they are caring for the roosters as well as dogs, horses, and cows that all were rescued. Commencement is a day students look forward to after years of studying and hard work, but cals graduation today was interrupted by antiwar protests. Hundreds of graduates filled a section of the stands. They were stomping their feet and chanting during the ceremony. As da lin reports, their protest had mixed reactions from the crowd. Reporter many of the new graduates did not have a normal High School Graduation four years ago because of the pandemic, so this commencement was supposed to help make up for some of that lost experience. Hundreds of propalestinian protesters in cap and gown made loud noises as thousands of people at Memorial Stadium celebrated the graduating students. Im proud that my peers feel they can have a voice here at berkeley. It wouldnt be berkeley without any protest, right . Reporter roommates angelina and sydney say they support free espeech. They dont think the protests take away from their big day. Proud that people feel comfortable to be, you know, expressing how they feel. Reporter many students say it was somewhat expected, theyre just glad cal moved forward with the commencement. They were fearful of a cancellation. Berkeleys a very social justiceoriented school. I think perfect includes social justice in the ceremony. Reporter angelina and sydney say they did a driveby graduation back in 2020 so having their parents, sibling, and friends here made the day very special. Having that connection, to like be able to give my parents a hug. To be able to give my friends hugs. Im a first generation. This is really important for my family. Reporter berkeley administrators prepared by adding security. The chancellor acknowledged victims from both sides of the war. She said shes saddened the conflict divided students and staff. Hundreds of protesters stood in one section to chant divest and hit the mt. Tal bleachers with their shoes. They made it hard at times to hear the speakers. So we can talk to Uc Administration and carol christ. Were going to continue to do stuff like this. Reporter there were no counterprotests, but some held up israeli flag, and some say the disruption was distasteful. Were here for our family. They worked hard. They worked hard during kov vid time, and now theyre not getting to graduate peacefully, and so its a little disappointing. I dont think to disrupt this moment is respectful for the people who have worked so hard. Reporter many students say its okay as long as no violence. Graduating college is a super big deal, very important, so i think were just excited to have this moment. Were ready to just celebrate, have a good time, and have a peaceful, celebratory day. Reporter angelina and sydney say we have been the extra fireworks, the commencement ended on a positive note to wrap up their four years at uc berkeley. Im just so happy. Theres no other words from me. Im so happy getting to be with my loved ones. Reporter the 90minute ceremony ended without any arrests. Berkeley Officials Say while the protest was loud, it was peaceful. And at the university of San Francisco, graduations not until next weekend but there was a rally this afternoon. You can see several tents and signs on the plaza. We talked to one student protester who said their recent meeting with the schools president did not go well. The blatant disrespect from father fitz after i gave my testimony about what its like to be a palestinian, specifically to this school, he dropped the mic and then after i he said that we were being disrespectful, i was being disrespectful, i told him check himself and then he left. Protesters say theyll continue their demonstration on campus until their demands are met. Scenes were much more intense on other College Campuses today. Students walked out of their Commencement Ceremony at Virginia Commonwealth University and police moved in to clear demonstrators and tents from the university of pennsylvanias campus. The school says its going to step up security for commencement later this month. And all of this about whats happening in the middle east, where parts of east rafah are now surrounded by israeli tanks after israels war cabinet gave the military the green light to expand the war there. And in northern gaza, more evacuations. Israeli Officials Say they are trying to prevent hamas from reestablishing its military capabilities. The u. N. Says more than 100,000 palestinians are now homeless in the area and running out of options. The white house said Israeli Forces may have violated International Humanitarian laws using u. S. Weapons. Israel disagreed and will continue to prosecute the war using u. S. Taxpayer money. Just yesterday President Biden was met with ceasefire protesters while on a Campaign Fundraising visit to the bay area. Thats what one demonstration looked like in portola valley, biden nearby visiting the home of a venture capitalist, and then went to visit the home of yahoos former ceo where in palo alto. Something we almost never see in the bay area, last nights cosmic weather, and whether well be getten an encore tonight. The most impactful event in 20 years. Its a fantastic handson learning experience for the students. Well talk about that show, plus are the clouds going to get in the way of tonight . Because theres still a chance tonight if you want to see that. Well go over all that, and of course, going to talk about the temperatures. When are they going to start coming down. Youre near 90 inland. Some better looking numbers if you want to cool down coming up. Lift the clouds off of. Virtual weather, only on kpix and pix . Well, as you know by now, people across much of the world got a rare glimpse of the Northern Lights thanks to a solar flare that popped off this week. These are pictures from solano county, lake tahoe, and modesto last night. And check this out, photographer jay wong who often sends us great videos shared this time lapse of the light show over sfo. He tells us this clip is made out of 728 photos. And the Space Weather Prediction Center says it could be visible as far south as alabama. So lets head to alabama no, lets not. Max darrow has some of the sights from the skies last night. In awe. Reporter its hard to put words to a sight like this. I just couldnt believe it. Reporter but this is what Javier Mendoza saw from Mount Hamilton on friday night, a stunning, rare display of the Northern Lights. It just made my passion for astronomy a little bit more solidified. Reporter mendoza is a grad student at san jose state, he shared his enthusiasm with professor aaron. This is the most impactful event in 20 years. Its just a fantastic handson learning experience for the students. Reporter the beautiful auroras seen in these photos taken in marin stem from a geomagnetic storm reaching earth. Its a beautiful experience. Nothing too dangerous because we have our Magnetic Field protecting us around the earth. Reporter distinguished professor of astronomy at uc berkeley alex took these photos from orinda. The red auroras are actually more rare than the green auroras, so that was special for me to see such an intense red aurora. Reporter but along with the beauty comes potential for problems for us on weather telecommunications and power systems. When these particles come in, they twang our Magnetic Field. Its as though you hit a bell with a hammer, and so it vibrates. And the vibrating Magnetic Field lines of earth then induce electric currents that go streaming along the power lines, especially the Long Distance lines, okay . And then when those currents reach transformers at local power stations, they can short circuit the transformers because theyre not used to such intense currents. One more look at the sky, mendoza is hopeful this rare celestial event will be a source of inspiration. Hopefully this makes an impact to especially our Younger Generation to pursue some field in s. T. E. M. Reporter if you missed it last night, you still may be in luck. Both professors believe you should be able to see some auroras tonight, though the show just might not be as dramatic as it was last night. Youll have to look north at around midnight to 1 00 in the morning. Your eyes may not be able to pick up on a ton of color, but if you take a Long Exposure photo with your phone just two to three seconds, the colors will likely emerge. And if you are not above the fog, then you are out of luck. Right, were going to see the fog build in tonight. But i think theres another issue in terms of seeing, this because the pictures are blowing up, and everybodys seeing these photographs which look really dramatic over us. But thats not the way it looked to the person standing there taking that picture. And theyre not even purposefully manipulating these pictures. Iphones have gotten good at resolving out night and dark colors so you can see them much more. And thats whats happening with a lot of these photographs. Let me show you some taken from two of our coworkers here. Our producer for the 11 00 newscast, week nite, took this. And it was her, sophie, and sara donchey, anchor of the late night news, who got in their car last night and drove to the marin headlands, rod owe beach, and these are the photographs that sophie took on her phone. And they do look spectacular. I called her today, because i wanted some perspective on what her experience was like in real life, not through the pictures, and i said give me a percentage. And she said i would say in real life the aurora looked about 25 as good as this. So this is more than twice as impressive as it looked to the naked eye. She could still see it. And i said, are you glad you went . Was it worth the trip up there late night . And she said, absolutely, im so glad i got a chance to see this. A couple ways to think about it, its not going to look like this when you go out. Tonight we have another chance for this, but its not as intense tonight. They rank these on a scale from one to five. Last night we were at the max on a five, which very rarely happens. Tonight were going to be at a four, which almost as rarely never happens. A four still pretty good. Wed be making a big deal out of four. So just know that. And then, of course, the other thing are the clouds. Lets go to the futurecast. What were going to do is use the High Resolution satellite imagery. It can get real specific, and its quite good, really, at forecasting the marine layer now. Its been a very fun item to use over the last several years. Watch what happens, were going to go slomo and watch the marine layer overtake the golden gate. The timeframe you need for the Aurora Borealis is 11 00 on. So lets go there and watch what happens as more of the marine layer starts filling the bay. Heres 10 00. Then we get into the window. Most of us are doing okay. In the south bay, youll have clear skies. But theres way too much light in the santa clara valley. Look north if youre going to try, but youre not going to have much luck there. Youve got to get rural or if you can get high elevation, youre going to have a better chance. In terms of the clouds, once we get past like 1 00 a. M. , they start filling in even more of the bay. So by like 3 00 or 4 00 ap, were clouded over. But rally the time youd be concerned about is 11 00 to midnight anyway. 11 00 to 1 00, thats the most realistic time to do this. Thats the aurora forecast. Lets talk about the other warm lately. These are todays daytime highs. These are the official numbers that have come in, 88 in concord. This is the peak, because from here the numbers are going to start going down. So lets use that heat risk map that weve started using during the big warm spells. This is today, the air glas orange show you with those temperatures near 90 we had a moderate level of heatrelated health impact. Enough to raise awareness for people who might be vulnerable. You can visualize the improvement. Still a little, but not as much. Monday, way less. The cooldown is coming. These are tomorrows daytime high, which are very similar to where we were today. Lets skip ahead to the end of this next coming week. And you can really see the cooldown there. Weve got temperatures that are going to be going back down to at least mainly 0s for inland valleys. Theres the sevenday forecast. San francisco and oakland are up first. You see the temperatures not budging a whole lot. Were pretty much going to stay right here. Near 80 for the north bay. Mid80s in san jose for much of the next seven days and. The inland east bay will also stay around 80 for much of the next seven days as well. Matt, over to you. Giants welcoming back a key bat that should help spark the offense. Plus, norman, bad news. I never graduated from med school. What . But the good news is.

A Long Time Coming for reopening of a ninehole golf course here in San Francisco, and now that its open, with had to pay it a visit and see what all the hype was about. Reporter public golf in San Francisco just got a major upgrade. After closing down for nearly a year, the new and improved Golden Gate Park golf course is back open to the public. People are in shock and awe once they walk up the hill and they kind of see what weve done here. Reporter through the first tee of San Francisco, a group of private donors funded a 2. 5 million renovation of the ninehole track. The community at times sees opportunity to raise the community up and this was definitely one of those times. This course is meant to last another 50 to 5 years due to the new irrigation, all new sprinkler systems are in place, all new pipe, so its set up for success for the long haul. Reporter the new clubhouse and practice facilities make it a public playground for golfers of all skill sets, but its the greens that keep people coming back. Everybody remember it as a as like a family kind of great time out. You come out here with your kids and your grandkids and you have a great time. But the greens right now, since it was redone, makes it more challenging, make it more fun to come out and enjoy the course. Reporter the course even offers something that used to be exclusive to private courses. Looking decent. Reporter hot dog bills burger dogs, fresh off the grill. Its been a great partnership. We get the meat on a daily basis from them. Its the same ingredient, same process, we cook it the same way. So its the same thing just not going to cost you an olympic club initiation fee. Reporter the park is not just an asset to the golfing community, it also serves as a home base for the first tee of San Francisco, a nonprofit that introduces the game of golf to underprivileged youths. The kids love it. I mean, they loved coming to this place even before its been transformed because it has kind of this cool familial vibe to it, but now they get to play it in modern great golf standards and a little bit easier and funner for them to play. So the feedback from our students has been great. Reporter but first he has a deal to keep them at Golden Gate Park for at least the next 15 years. After investing in an asset for community, public play will continue to support the program best known for growing the game. Yeah, people coming and supporting this facility, they absolutely are in one way or another supporting first tee and our efforts to, you know, help underserved kids in the community. The course looks great, and youve got to wonder, people who have been golfing their there for decades, it closes down, i want to know their reaction the first time they went out there. Whoa, this is way nicer than it used to be. Well, it does look really nice. Yeah. And golf courses are always needed because yes, they are, because the tee times go quickly. Im always looking for one, so. Anything to avoid the olympic club initiation fee. I dont think i have that coin to throw that down yet, no. Thats right. Thank, matt. Coming up in our next half hour, some people in san jose are so bad at recycling trash inspectors are checking bins and rating how well they did. Well, we see some nonrecyclable paper, plastic wrap. This is an, yeah. A Pilot Program meant to clear up confusion about what goes where. Plus, an important study among Asian American women. Its tracking an increase in lung cancer cases among people who havent smoked. We talk with from cbs news bay area, this is the evening edition. Now at 6 30, bay area researchers trying to unravel a medical mystery. Lung cancer is the second most common cancer in both men and women in the united states. And the disease is now affecting more and more Asian American women and doctors arent really sure why. And now a bay area bay study finds that 80 of Asian American women with lung cancer never smoked. Theyre also 1. 5 to 2 times more likely to be diagnosed than any other racial group. Elizabeth cook spoke with the researchers and patients who are working to figure out whats going on. Reporter vicky doesnt take walks like this for granted. Each step has a purpose, and shes rarely by herself. And if you happen to pass them, you might think these are just two friends catching up, but the women who join her all share a common bond, they all have stage four lung cancer. Living with stage four cancer means, you know, you have a bomb strapped to your chest and it could go off at any time. Reporter it all started five years ago when she got a call from her doctor. But i remember vividly that he called me while we were out having dinner and left a voicemail. Reporter before she knew it, vicky was sitting in an oncologists office. The word cancer comes out of the doctors mouth, so thats kind of not good. Reporter vicky never smoked a day in her life but yet this 48yearold mother of two has stage four lung cancer. I was asking them, im like, okay, so how long is treatment, and you know, when are with done with this. And no one had told me up until then that it was stage four, so it was incurable. And so, you know, i would basically have to live with this condition for the rest of my life. And the best Case Scenario is that i live with this condition for the rest of my life. Reporter vicky is now 53 and the treatments have been brutal. Theyve given her high Blood Pressure and high cholesterol. The cancer has now spread to her abdomen. But its not the physical side effects that hurt the most, vicky has two daughters who were 13 and 15 when she was first diagnosed. They know they have cancer. And we dont talk about sort of staging. We dont talk about cures or anything like that. They just know that ive had cancer for, you know, five years now. Reporter a few years ago, vicky was asked to participate in a Research Program at ucsf called fans. Fans standing for female asian never smokers, launched 15 yours ago by doctors scarlet gomez and iona chang. A first of its kind study in the u. S. On why lung cancer rates were rising among asian females who never smoked. Lung cancer rates actually have been declining over the past several decades, but what was sort of emerged was the exception was among Asian American females. Reporter the doctors hope the fans study leads to the development of more preventive measures and screening but also grab the attention of the folks with the deep pockets. Right now less than 1 of funding from the National Institute of health goes to diseases that impact the Asian American community. There is this perception that asians dont get sick. We have very low rates of disease, and so their primary focus is to fund health research, relies on those statistics. Its just made us very strong advocates to really give a voice to be able to speak out about the need to look at specific asian ethnicity populations to provide the data. Reporter vicky isnt spending her energy wondering why or how she got lung cancer. Well, when you get diagnosed with cancer, i think you learn to control the things that you can and let go of the things you cant. And i have not tried to probe why i got cancer. I dont think its, like, a healthy exercise. Reporter instead, shes turning her pain into purpose by reaching out to other women like 34yearold kit ho, who she recruited to also be part of the fans study. If my tissue, if my saliva can help the researchers to find more medicine or find more ways to identify people early, then i want to be part of it. Reporter kit was diagnosed on thanksgiving of last year. Doctors discovered four tumors in her brain that they believe were linked to lung cancer. Just like vicky, she never smoked. Shes also a mom. I was just thinking, why did i get it . Yeah, and the most thing i was thinking when i was diagnosed was my two little kids. Because they are 2 and 4, and so and lung cancer, being a nurse, i know its not a good outcome. Reporter kit will often join vicky on her walks. They are allies in the same fight. Its like a safety blanket for me to know other people are in the area. Reporter if cancer has taught her anything, its that life can change in an instant. Vicky is focussing on the things that bring her joy, family, friends, and helping others know that even in their hardest moments they wont have to walk this path alone. I want to do everything i can to make this diagnosis sort of meaningful for the world. The fans study looks at a patients genetics and Family History as well as environmental and lifestyle exposures. They are still looking for participant, especially older asian women who do not have lung cancer. To join the study for more information on the study, go to our website, kpix. Com. And thats where you can also find all of our special story this is month highlighting asian cultures, history, and issues important to the bay areas aapi community. And Community Members in San Franciscos alamo square rallying against hate after a neighbor had been targeted for extremely hateful racist attacks. The victim says he was sent two hateful packages within a span of ten days. A doll with a noose was even delivered to his front door. Video efrom nearby surveillance cameras show the person that neighbors claim left the doll on the night of april 26th. People gathered at alamo square park to support Terry Williams and speak out against the hateful messages that he received. Neighbors say that they have been sending williams door camera videos and will continue to support him. We contacted San Francisco police to get more detail, and they did confirm that a hate Crime Investigation is underway. Spokesperson did not confirm the incidents are connected but said no one should be targeted because of their race, religion, gender, sexual orientation, or any other shared characteristic. A house fire on l. J. Ridge lane not far from evergreen valley high school. It broke out around 3 30 this afternoon. It took firefighters about an hour and a half to put it out. No one was hurt but two residents have been displaced. In west oakland a fire damaged a church and destroyed a nearby home. This one at can last night at 27th and west streets. Here is video showing big plumes of smoke from the burning buildings. Around 60 firefighters were on scene of this fire. Crews had the blaze under control before it reached most of the church. The fire started at the home next door and the cause is still under investigation. And speaking of oakland, today was the first day on the job for the Police Departments new chief. Lloyd mitchell is an air force veteran who previously served as the police chief of lubbock, texas. Mitchell replaced opds former chief, leronne armstrong, who the mayor, sheng thao, fired more than a year ago. She is getting a College Degree more than 80 years after she graduated high school. How an east bay college honored longtime park Ranger Betty Reid Soskin next. you made a cow actually its a piggy bank. My inspiration to start saving. How about a more solid way to save . Im listening. Well, bmo helps get your savings habit into shape with a cash reward every month you save. Both cash reward . And theres a cash bonus when you open a new Checking Account to get you started. Wow. Anything you cant do . mugs. Bmo today was the grand opening of San Franciscos newest park atop yerba buena island. Panorama park features 360degree views of the bay area and this point of infinity sculpture by a japanese architect. The park is just the latest addition to the larger plan to revitalize yerba buena and treasure island. Every day we can show you beautiful views of San Francisco from the bay cameras on top of the Mark Hopkins Hotel and when it comes to views, it is hard to beat the top of the mark, which turned 85 today. It did. Standby one. We had to get the drummers seated and give him his cue before he could begin playing. Earlier this week they marked the anniversary with a live band, great drink, great vibes. It was 1939 when top of the mark became San Franciscos very first rooftop bar. It was a very bold idea. Nobody had done it before in the city, and he wanted to do it. He was concerned with two things. One, he didnt know what name he would give it. And two, he was really scared that people wouldnt take an elevator up to have a view with their drink. Go figure how times have changed, right . And also while we are broadcasting to you live tonight from the spacious studios on battery street, we actually began broadcasting 75 years ago from the attic above the bar, becoming the First Television station in northern california. Well, the oldest u. S. National park ranger can now add doctor to her list of accolades. Betty reid soskin was awarded an honorary doctor of humane letters degree at cal state east bay. Soskin graduated high school in oakland at the start of w0rd war ii and then worked as a file clerk at the richmond ship yards. Today she was honored for her hard work and service. California State University bay is proud to confer upon Betty Reid Soskin the Honorary Degree of doctor of humane letters. Soskin didnt become a park ranger until she was 85 and retired two years ago. She is now 102 years young. Looking pretty good too. Mmhmm. You can see bumper stickers everywhere, keep tahoe blue. When we come back, a look at what makes the lake so distinctly blue in the first place and how its color is shaping up for this summer. We started making San Francisco bay gray today. It is may gray season after all. Marine layer is back in this morning and its going to be more widespread tomorrow. Thats good news if you wanted to start cooling the temperatures down, particularly inland. Ill show you how were going to start doing that in this forecast coming up. The warm temperatures inland this weekend are giving us a little bit of a preview of summer. With that, theres a lot of anticipation for how blue lake tahoe will appear following two consecutive winters with above average snow pack. But there are a lot of factors at play that give the lake that pristine blue look its known for. And Andrew Haubner how sediments and tiny creatures called zooplankton give lake tahoe its iconic blue hue. Reporter one of the nations most pristine bodies of water. And for longtime residents zach and valerie, gazing out over the lake never gets old. Oh, it cant be beat. Ten out of ten. Its just a gem. People leave here and always come back. Reporter but what makes the watt sore blue . Experts say underneath the surface you have phytoplankton, which are plant, and zooplankton, which are animals. Both are tiny creatures but vital to the ecosystem. Zooplankton feed on phyto plankton and each other depending on size. Sometimes the phytoplankton, different types of phytoplankton flourish at different times. That will affect the color and clarity of the water. Reporter however, uc davis professor and interim direct fer Tahoe Environmental ResearchCenter Alexander forest says thats only one piece to a much larger puzzle. It depends on the sediments, the inorganic particles in the water. Reporter it comes down to balance, the color and clarity is dictated by factors including snow melt runoff, sediments carried down by stream, annual water temperature, and their collective impact on the various species of phyto and zooplankton. We as scientists really need to understand how they all link together to understand how to control the clarity, because claritys part of it, but also the color. Reporter last year the lake was the clearest its been in decades. Dr. Forest says it boils down to the quantity and quality of snow melt. Last year they were both high. This year the snow came in much later in the season, impacting the quality of the runoff. We are at the same water quantity but the quality, the water thats coming into the watershed is much warmer. Reporter it impacts growth, sediments from the mountain and roads will also play a big factor in the lakes clarity. It is too early to tell. Hoping for more clarity to continue. Reporter but for zach and valerie, the lake is already off to a good start. I think so because i think just the weather weve gotten, a lot of the precipitation and everything, so its been really helpful. And tahoes Environmental Research center says it will be conducting its First Official clarity test of the season in about two weeks. And darrens got something happening up in canada, i guess. Yeah, not the most pleasant reminder, but i got to start out with an image of todays satellite, which is going to bring back memories of last year and maybe even for us years before that. If you look at High Resolution satellite on here, can you see the big plume of smoke this afternoon coming out of British Columbia . Here we are, things look clear. A marine layer showing up. Theres that big plume of smoke. Several new fires burning in British Columbia. Its early, midmay, and theyve started wildfire season out there, after what was a warmer and drier than average winter. Were coming off our winter, which was pretty good, but British Columbia was not that way. It was warm and dry up there, and the forecasts coming out of canada for this summer are for another intense wildfire season. We saw so much smoke coming out of canada last year that its a little concerning to be in may and see it starting up all over again this early in the season. Its not the most fun thing to look at. Heres the forecast over the next few days. Doesnt look like that plume of smoke is going to turn into anything serious for the lower 48, but there are hazardous levels of air quality across the plains of canada, across alberta. Theyre breathing in unhealthy air today from that. Heres our story back at home. We were near 90 today for concord, livermore, san jose was 83. Santa rosa was 81. These numbers are about 11 degrees above average for this time of year. This is the top. Were going start coming down after this. Temperatures start cooling, and you can see part of the reason for that, obviously, time lapse of this morning into the afternoon as the marine layer was streaming in through the golden gate. Lets put it into the futurecast and watch it do that again tonight. Weve got it on slow motion here to pick out as much detail as we can considering you still have a chance tonight to see some of the aurora. Its less intense than it was last night. Last night it was a five on a scale from one to five, and a way to think of it would be for visibility for those of us that are this low latitude. Today its at a four on that scale. So one notch lower. Still a pretty good place to be, but it wasnt a super impressive show to the naked eye last night, but you could see it if the skies were clear and you got away from city lights. Probably the same way again tonight. So just watch where the marine layer is here in the overnight hours. It wouldnt matter because you dont want to be in the immediate bay. If you really want to see the Northern Lights tonight, youve got to get as far away from city lights as you can and anywhere the marine layer would be, obviously. Those daytime high, you still have areas of orange shading all of the interior valleys, showing you on the scale there that were still getting up to a moderate category for heatrelated health impacts. Scale goes a lot higher than this. Its not an overly concerning situation, but its something to raise the awareness on. Heres the good news, watch tomorrow. Less of it. Thats sunday. Heres monday. Less of it. So lets go to the sevenday forecast and ill show you what this looks like. San francisco and oakland, youre up. Your numbers for oakland stay around 70. Temperature, north bay, youre in the mid70s for the next few days and then near 80 for much of the early part of this week. San jose in the mid 80s for much of this sevenday forecast. And the inland east bay will stay right around 80 degrees as well. All right, brian, over to you. Thanks, darren. Coming up next, tougher than you think to recycle properly. How one bay area city is flipping the script to help the Community Find the right answers. Were in the middle of. Seizing the date in the middle of the perfect pairing. And parking it here for the night so come get away. Together. Illinois the middle of everything. Boy is that ever a typical summertime shot of fog. Tonight this weeks project earth report as californians, we have a reputation for being environmentally conscious. But in many way, the data tells a different story. 95 of californians have recycling bins, but only 30 of recyclables actually get recycled. Most ends up in landfills. In san jose, instead of flipping its lid, the city decided to flip yours. Anne makovec explains. Reporter Anthony Santa maria is a man on a mission. Early in the morning he flips the lids of dozens of recycling bins. Well, we see some nonrecyclable paper, plastic wrap. Reporter anthony is part of a new Pilot Program run by the city of san jose. The idea . To eyeball the contents of curbside bins on Collection Day to give residents a little feedback as to why now. We are seeing a lot of increase in unacceptable materials in the recycling carts that are nonrecyclable or either recyclable materials that are too dirty to recycle. Reporter contaminated bins are on the rise. The citys director of Environmental Sciences explains. So a recycling cart becomes contaminated when the wrong materials are in it, particularly liquids and food. Because then they spread out on the paper and other products in the cart that make it so we cant recycle it anymore. Reporter if they cant be repsychled, the item ends up in a landfill, where the food and drinks slowly rot, creating methane. It impacts rates. So the more that we have garbage in the recycling cart, the more the program costs, which means the more the rates go up for a community. Reporter back to the bins. Stickers get attached to each cart, either a green good job or a red oops with tips on how to do better. This is an oops, yeah. Oops is sort of semihumorous. Its not that negative. From my perspective, its far more effective the light touch than the negative touch. Reporter dr. David is an expert in Human Behavior at Stanford School of medicine, he applauds san joses approach, especially the added visual tips. If on top of that youd show people how to do it, you feel a part of the team rather than part of the problem. Reporter as for the locals i think its good. Reporter san jose resident dirk with his two kids benjamin and amelia. I think its a good way to help the citizens of san jose doing a better job. Reporter the family will soon move back to the netherlands where the recycling rate is 80 compared to san joses 57 . If you see a change, thats a perfect result of the project. Reporter it is a work in progress. Out of all the ones i tagged, i believe there were two good jobs out of i tagged 85. Reporter the hope . To make recycling as simple and easy as childs play.
