That memory . With that, its very simple. Whenever i feel sad, depressed, worried, i think of that day and the courage of those First Responders and it lifts me up and it works every time. Really . When you have witnessed so much courage and heroism, there is no way you can complain about life. Not wanting to find a solution. Thats a pretty remark annual thing if thats what you take away from it. Yes. Not all of the loss and the pain and the horror but you saw the beauty and resolve of people to save others. Yes.

path and we are seeing what s left behind, what is the flooding looking forward? this is the result of that 10 inches plus of rain, debris flows, mudslides, you saw it in stephanie s live shot a moment ago. they are so dangerous. zoom into what s some of the best video we have had come into cnn, look at the debris caught up in this. there are boulders, there are rocks, there are entire tree trunks, sometimes homes and vehicles can get swept away in this torrent of mud and debris that can travel over 30 to 40 miles per hour. we talk about burn scars quite often and they are so dangerous for the mountainous terrain of southern california. these burns, the forest fires can occur several years prior to this event, but when we see the burn scars lasting effect on the landscape, it s when we get these heavy rain events in the middle of summer when it s its driest when we have the biggest impacts.
i guess the question is what can we do now if anything to reverse some of this damage? well, let me put it this way, erica, if we don t stop burning fossil fuels rapidly, our summer of heat hell will be considered a cool summer in the future. now, scientists for decades have been able to attribute weather events like coastal flooding, heavy rain events as well as these extreme heat events to climate change. but now the world weather attribution initiative, the report we re talking about has the ability to compare our current climate, which is 1.2 degrees celsius above post industrial averages to that of the past. what it s finding is the role of climate change is absolutely overwhelming. take, for instance, the current heat wave this month of july across north america with man-made climate change and actually 2 degrees sels rouse warmer than what it would be without these heat-trapping gases that we release into the atmosphere and they re becoming
the last handful of decades, since the industrial revolution, katie. chris, i wanted your expertise, though. let s talk about how extreme the weather has been. what is this connection, though, who this insane heat that s going on across parts of the united states, but simultaneously the amounts of rain and flooding that we re seeing at the same time? it s a pretty easy formula. for every degree of warming that the atmosphere warms, there s about 7% more moisture in it. it manifests in heavy rains. what we ve seen in recent years, a lot of research shows that we ll see increase in his heavy rain events, but it s more than just that. the ocean s water is also very warm. look what s going on in the florida degrees. it s about two degrees cooler than a hot tub.
