organisation says: there is a 66% chance that we will break the 1.5 degree temperature threshold for at least a year. there is a 98% chance of the warmest year on record before 2027. arctic heating will likely be three times higher than the global average. and the reason for these worrying predictions? temperatures being driven up by ongoing carbon emissions plus the likely onset of a naturally occurring el nino event which can trigger more extreme weather and climate events, including severe rainfall and drought, depending on the region. laurie goering is the climate change editor at the thomson reuters foundation. i asked her to explain the significance of these figures. i think the real message from this is that these climate change impacts are coming much faster than scientists had predicted. scientists are inherently conservative and what we are seeing is that a lot of different things from hate to sea level rise are probably going to happen a lot faster than we had
need to advance a lot, not only our efforts to quickly cut emissions so this doesn t get any worse, but also to adapt to some of what is coming and make plans for a quite a changed world that may be coming up. these are serious problems like losses of more and more clocks around the world if we see temperature extremes because in many places they won t do as well. if we see extreme weather, which is already causing huge problems everywhere, that s likely to get worse, and he waves in themselves are a huge risk that is under recognised and a real threat to human health. you under recognised and a real threat to human health. under recognised and a real threat to human health. you heard laurie goerin: to human health. you heard laurie goering talk to human health. you heard laurie goering talk about to human health. you heard laurie goering talk about extreme - to human health. you heard laurie. goering talk about extreme weather events. it would appear that is what is happening in
uncertain future. we missed christmas and nears coming up, we have a big fear. we are trying to clear out beds but there are quite literally no beds in this hospital. it s just as easy as getting vaccinated, being wise about who you re around. at this point, i m just asking for your help. reporter: and we also learned tonight the white house lifted a temporary ban on travel from eight south african countries nears day, a decision the world health organization has been urging, jamie. reporter: and the the world health organization also said today santa is immune from covid so we have good news ahead of christmas. nancy chen, thank you. a. yuccas: a powerful winter storm could bring five to eight feet of snow to the sierra nevada, while other parts of the country could be in store for a record warm christmas day. cbs s lonnie quinn joins us now with the latest forecast. talk about extreme, lonnie.
