The planet is warming at a pace not experienced within the past 1,000 years, at least, making it “very unlikely” that the world will stay within a crucial temperature limit agreed by nations just last year, according to Nasa’s top climate scientist.
“The data shows major reorganization of the cloud system… I consider this as the most singular of all the things that we have found, because many of us had been thinking the cloud changes might help us out, by having a strong feedback which is going the other way instead of amplifying it.” — climate scientist Veerabhadran Ramanathan
Here at the Energy and Environment blog, we cover, regularly, the tipping points of climate change — how, for instance, the glaciers of West Antarctica may already have passed a key threshold that leads to unstoppable melt.
At its annual meeting in Dallas, ExxonMobil shareholders rejected a series of resolutions Wednesday calling for climate action, including resolutions backed by CalPERS, the California Public Employees’ Retirement System, as well as New York state Comptroller Thomas DiNapoli and the Church of England. Shareholders did pass a measure to let minority shareholders nominate outsiders for seats on the board, raising the possibility that a climate activist could someday become a director at Exxon.
When it comes to climate change, it’s often difficult to convey an appropriate sense of urgency. After all, this is a problem that been building for decades, and will take decades of coordinated effort to solve.
An unusually intense May wildfire roared into Fort McMurray, Alberta, Canada, on Tuesday, forcing the largest wildfire evacuation in province history. The flames rode the back of hot, windy weather that will continue through Wednesday and could pick up again this weekend.
The number of climate refugees could increase dramatically in future. Researchers of the Max Planck Institute for Chemistry and the Cyprus Institute in Nicosia have calculated that the Middle East and North Africa could become so hot that human habitability is compromised. The goal of limiting global warming to less than two degrees Celsius, agreed at the recent UN climate summit in Paris, will not be sufficient to prevent this scenario.
