Yes: «For political leaders and business people, we think it is important for you to know that it’s extremely unlikely that scientists are exaggerating the threat of the climate crisis. It is far more likely that things are worse than scientists have said»
I am disappointed that Science has allowed an abstract of a, otherwise good, paper to say that planting trees is "our most effective climate change solution to date". This is factually wrong and certainly a distraction. 1/2

The Greenland ice sheet just lost 22 billion tonnes of ice by surface melt IN A DAY. Snowfall compensated less than half of it. This contributes to sea level rise…
#FaceTheClimateEmergency
This event has generated the 3rd highest ablation rate (-12 GT/day) in the recent ice sheet history (from 1950). For a record surface melt production of 22 GT/day, 10 GT was absorbed by the snowpack thanks to the recent heavy snowfall.

…And Belgium plans to build new fossil gas power plants, to replace existing nuclear ones! This is bad for climate and air quality, bad for fossil energy independence, and bad for energy security. Yes, nukes need to be replaced by renewables asap, but not now.
Non, le mot “effondrement” est mal choisi en français. La situation est très grave, mais l’humanité A les moyens, si elle en a la volonté suffisante, d’empêcher que la Terre devienne partiellement inhabitable. Il faut sortir des combustibles fossiles et arrêter la déforestation !
I'm sometimes called ”political". But I've never supported any political party, politician or ideology. I communicate the science and the risks of failing to act on it.
And the fact that the politics needed don't exist today, neither to the right, left nor center. ->

Air-conditioning is a climate killer. Its use should be minimised. Buildings need to be made or renovated so that they require as little AC as possible. Planting trees near buildings can help.
