yet since paris, it has rained for the first time on greenland summit. the amount of c02 in the atmosphere has reached record levels. heat waves have scorched countries around the world. droughts, storms, forest fires and floods have all become more intense, more recurrent and more intense, more recurrent and more commonplace. and sea levels are rising threatening small island states and bigger countries alike. we have the science and resources and the urgency, what then is holding us back? my dearfriends, only one variable remains and it is us. we have to make the choice to address this. we have to choose but necessary actions. we have to listen to the science and increasingly the global population who are demanding action. my dear, dearfriends, we have run out of excuses. it is time to do the right thing. in the words of frankie the dinosaur who addressed the general assembly, let us not choose extinction let's work together as one global family and use the capacities... you together as one global family and use the capacities. . ._ use the capacities.
when it first went to get was mentioned in 80 the west coast of greenland but had not been accessible. the ice was too thick and they tried to walk out they all died. now 40 years later cruise ships go up into that area. and then in this south in antarctica the species who had been living there for 5000 years have been supported by both species of penguins slurs of bones and stuff like that you can carbon date to get an idea of which species for the last 5000 years we've been there. these are visible changes. we had a lot less kelp burning kelp coverage is really, really diminished in southern california. okay that's fine the whole ecosystem but certainly massively overstretched remember their heat waves in the ocean also. these are all in the ocean are getting stressed during these heat. these people live on land they've never been to see. i went swimming two days ago in the ocean it was great after this interview i'm going again. it's great for swimming. >> anyone who lives in san diego knows the beaches have been warmer as of late. samantha, just tell me you detailed so many disast
the jet stream first — some big patterns here, big peaks and troughs, you can see a peak going over greenland there, trough in the north atlantic, then peaking again across western parts of europe. and when we see this sort of pattern, that gives us an indication there'll be a lot of mixing in the atmosphere between the northern and southern climes — so pulses of cooler air pushed up ahead, then back to cooler air again. lots of low pressures forming in the north atlantic as a result of these temperature contrasts as well, and towards the end of the week it looks like it will turn a little bit colder. so let's summarise what the next few days will look like — bouts of heavy rain particularly across western areas with low pressures approaching, that also means gale force winds, but we will also see a lot of mild air, very mild air, in fact, streaming in from the azores. now this is the weather map for monday — and a big low pressure with winds blowing around it like so, that low pressure is also scooping up that mild air from the south. see, the mild south—westerlies here. so outbreaks
