warmer climate within our planet made this likelihood 80 to 90% more likely than before manmade climate change was even in existence. so let s talk about the elements that put that in together. you can see on this latest satellite imagery that is a cut-off low-pressure system. that is a telltale sign of climate change. slowing down the movement of the easterlies across the planet. and that, of course, allows for systems to bring rainfall into the same locations, for long periods of time. and become more frequent, as well. you can see the rainfall totals starting to pile up, now, into the region. so that is our next area of concern. michael. all right. keeping an eye for us, derek van dam. and also, journalist chris burns in belgium. thanks to you, both. now, the u.s. centers for disease control and prevention is now warning those who have a compromised-immune system. the covid-19 vaccine may not be effective for you.
a record number of fires this year. it s still not even the middle of summer. all the signs for disaster are there, and yet what i don t understand is there s still a resistance p. what really needs to happen to avert something much worse? that is the multi-million-dollar question, ana. there s not going to be a pearl harbor of climate change where everybody feels it all at the same file. we adapt to the awe solve quickly. you saw what happened during the pandemic. you can normalize the pain right there. the conversation is shifting not from mitigation stopping the root of the problem, which is burning fossil fuels. that s the core of this. it s adapting to the new normal and strengthening the communities. they re raising the streets in miami, putting in bigger pumps, changing the zoning in california around fires, and
of u.s. last week was 150 times more likely because of manmade climate change and they say more lives will be be p llost. (upbeat music) - [narrator] this is kate. she always wanted her smile to shine. now, she uses a capful of therabreath healthy smile oral rinse to give her the healthy, sparkly smile she always wanted. (crowd cheering) therabreath, it s a better mouthwash. at walmart, target and other fine stores. look, this isn t my first rodeo and let me tell you something, i wouldn t be here if i thought reverse mortgages took advantage of any american senior, or worse, that it was some way to take your home. it s just a loan designed for older homeowners, and, it s helped over a million americans.
a group of scientists have a sobering detail for us. this disaster was not merely an act of nature but also manmade. it would have been virtually impossible without the influence of human-caused climate change. that is the consensus of an international team of 27 scientists. their study from world weather attribution also fiend that climate change made the heatwave at least 150 times more likely. now the western u.s. is bracing for another heatwave, and it could be the most brutal one yet. we have a reporter in las vegas, which could see a record high. when i was there a few days ago, it was 100 degrees at 9:00 at night after the sun went down. how much hotter is it supposed to get, and how is the city coping? reporter: well, look, anarks it can be 100 degrees at 1:00 or
terrible drought is raising the wildfire risks. and the northeast also very steamy, records were set yesterday in new york, boston could hit 100 degrees today for the first teaime in ten years. and studies show severe heat is three to five degrees hotter than it used to be because of manmade climate change. pedram javaheri explains for us. yes, when looking at this sort of a heatwave, this ridge of high pressure is often responsible and we talk about the heat dome that develops. and you have to keep in mind that with an area of high pressure, you get sinking air, when it sinks, it warms by compression. like when you pull in a bicycle tire, you see the bike pump itself warms up because you are compressing air within that pump into the tire and that is essentially what is happening on the broader scale and the
