core, which is the warming of the planet due to carbon pollution, fossil fuel burning. so that s most important. we can prevent this from getting worse if we act on climate now. that having been said as you allude to, some of these impacts are now baked in. we are going to need to deal with this. that means greater resiliency. that means adaptive measures to help deal with the impacts of these destructive storms. so it s really both. it s adapting to the changes that we re already forced to deal with and preventing it most importantly from getting worse by acting on climate. michael mann, as always we really appreciate your expertise. thanks. as we try to get our heads and arms and hearts around this incredible disaster. and illinois is another state hit hard by the tornados. six people died at an amazon workplace, warehouse that took a direct hit from a really fast
the level of sophistication of the science now. we can do what s known as detection and attribution. it is a fancy way of saying we can do sort of a before/after comparison with the climate models. we run the climate models without the increase in carbon pollution from fossil fuel burning and run the models including the increase in car upon pollution. we see how often a particular extreme event happens in both cases. in many of the cases that you re talking about, what we see is that the event is observed to have been astronomically unlikely without the additional warming from human activity. and in the models that include that, we find that these sorts of events are likely to happen. here s the bad news. what we re seeing now, the models tell us, is baked in. that s what we re going to have to deal with now for years to come. it gets worse if we don t reduce carbon emissions dramatically in
and the world s smallest baby more than a year later, this little girl finally leaves hospital here in singapore. hello and welcome it s 8am in singapore and 1am in london. global warming is accelerating, and human influence is to blame that s the warning from a damning new report from the un and its secretary general. antonio guterres says the evidence can not be denied greenhouse gas emissions from fossil fuel burning and deforestation are choking the planet and putting billions of people at immediate risk. it s the most comprehensive climate change study ever and is produced by hundreds
all signed off on the findings. in short, greenhouse gas emissions from fossil fuel burning and deforestation are choking the planet, and putting billions of people at immediate risk. the report warns that the global average temperature rise could reach or exceed 1.5 degrees celsius in the next 20 years ten years sooner than expected. it said rising temperatures will cause more frequent, extreme weather events across the globe. and warned that irreversible changes are already ongoing in melting ice sheets, rising sea levels and increasing acidification of the oceans. but the report also stated that climate change could be slowed down, with rapid and sustained emission reductions. 0ur science editor david shukman has this report. as the world gets hotter, it s becoming more threatening. the terrifying scenes of mass escapes from greek islands, burning amid heatwaves, just as devastating fires
and 195 countries agree with him, as they have all signed off on the findings. in short, greenhouse gas emissions from fossil fuel burning and deforestation are choking the planet, and putting billions of people at immediate risk. the report warns that the global average temperature rise could reach or exceed 1.5 degrees celsius in the next 20 years ten years sooner than expected. it said rising temperatures will cause more frequent, extreme weather events across the globe. and warned that irreversible changes are already ongoing in melting ice sheets, rising sea levels and increasing acidification. but the report also stated that climate change could be slowed down with rapid and sustained emission reductions. our science editor david shukman has this report. as the world gets hotter, it s becoming more threatening.
