If emissions are slashed in the next decade, average temperatures could still be up 1.5C by 2040 and possibly 1.6C by 2060 before stabilising.ДЄnd if, instead the world continues on its the current trajectory, the rise could be 2.0C by 2060 and 2.7C by the centuryвЂ™s end. вЂњBut the more we limit warming, the more we can avoid or slow down those changes.вЂќД«ut even to slow climate change, the report says, the world is running out of time. вЂњWe are now committed to some aspects of climate change, some of which are irreversible for hundreds to thousands of years,вЂќ said IPCC co-author Tamsin Edwards, a climate scientist at KingвЂ™s College London. GreenlandвЂ™s sheet of land-ice is 'virtually certain' to continue melting, and raising the sea level, which will continue to rise for centuries to come as the oceans warm and expand. the greater the odds we cross thresholds that we can only poorly project,' said IPCC co-author Bob Kopp, a climate scientist at Rutgers University. West, releasing record carbon dioxide emissions from Siberian forests, and driving Greeks to flee their homes by ferry.ДЇurther warming could mean that in some places, people could die just from going outside. Wildfires fuelled by heat and drought are sweeping away entire towns in the U.S. This year, heat waves killed hundreds in the Pacific Northwest and smashed records around the world. The 1.1C warming already recorded has been enough to unleash disastrous weather. That means that, even as societies move away from fossil fuels, temperatures will be pushed up again by the loss of the airborne pollutants that come with them and currently reflect away some of the sun's heat.ДЄ rise of 1.5C is generally seen as the most that humanity could cope with without suffering widespread economic and social upheaval. The report says emissions 'unequivocally caused by human activities' have already pushed the average global temperature up 1.1C from its pre-industrial average - and would have raised it 0.5C further without the tempering effect of pollution in the atmosphere. And the cost of inaction keeps mounting.' President Joe Biden tweeted Monday: 'We canвЂ™t wait to tackle the climate crisis. British Prime Minister Boris Johnson said he hoped the report would be 'a wake-up call for the world to take action now, before we meet in Glasgow'.
