to change more quickly. and that s going to cause quicker changes to the weather and temperatures we experience every day. well, you know, most residents would say that we should worry about those tipping points and those feedbacks, we should worry about if we trigger those in the climate system. we re probably not at the brink of triggering them at a rapid pace at the moment. we might have to worry about some of those thing there was a paper this week suggesting that some of the ocean circulation patterns may be disrupted as soon as the middle of the century, or even sooner. there are worries about some of the ice melting and that affects how much sun is absorbed in the higher latitude oceans, how much will be reflected back. that can make a difference in heating the planet up faster. but generally speaking, i would say the conventionalism, at this moment, 1.2, 1.3 degrees celsius
how our climate has evolved and we report on this data five days behind real time so we know from earlier in january, earlier injuly sorry, we had the hottest day ever recorded in our record which goes back to 1940. but if we go back to proxy records, it is the hottest day in human history. it was also the hottest three week period globally. that is also pretty warm heat waves, marine heatwaves in the north atlantic and extremely low sea ice in antarctica for this time of year. we are really seeing a huge number of extreme events in the climate system. find events in the climate system. and ou are events in the climate system. and you are seeing events in the climate system. and you are seeing a events in the climate system. and you are seeing a clear progression, i m going to put onto the screen a graph of 80 julys and the data you re from that and you can clearly see from the graph coming up where we are on the right hand side so you can seejust the we are on the right hand side
and parts of asia. well, now, leading scientists have told the bbc they are concerned by the recent run of new climate records being set, saying the speed and timing of them is unprecedented. some fear we re already witnessing worst case scenarios. georgina rannard explains. sweltering temperatures in spain and dangerous wildfires in greece. millions have struggled through powerful heatwaves around the world in recent days. now scientists are poring over a run of climate records that have not only been broken, but smashed, and alarm bells are ringing. it s true to say that the models, the climate models that we have, do a very good job of predicting the climate system, but in the kind of larger scale. so, the fact that we re seeing the world warming because of greenhouse gases is not unexpected. but seeing some of these records being broken, you know, these marine heatwaves in the north atlantic,
struggled through powerful heat waves around the world in recent days. now scientists are poring over a run of climate records that have not only been broken but smashed and alarm bells are ringing. it’s broken but smashed and alarm bells are ringing. bells are ringing. it s true to sa that bells are ringing. it s true to say that the bells are ringing. it s true to say that the models, - bells are ringing. it s true to say that the models, the - say that the models, the climate models that we have to a very good job of predicting the climate system but on a larger scale so the fact that we are seeing the world warming because of greenhouse gases is not unexpected but seeing some of these records being broken, you know, these marine heatwaves in the north atlantic, the severe decrease in antarctic sea ice was not expect it and it s something we re going to have to work to try to understand. find we re going to have to work to try to understand. try to understand. and this is why
