Canadian permafrost thaws 70 years earlier than predicted

The fact is the IPCC is well aware of the political headwinds it faces and its reports are conservative -- they have always underestimated the likely outcome because it is hard enough to get sign-off on even that, plus the consequences of overstating it is harmed credibility.

It’s been a couple of weeks now since the IPCC report came out. You know what it says. If the whole damn species pulls together in a concerted effort “without historical precedent”— if we start right now, and never let up on the throttle— we just might be able to swing the needle back from Catastrophe to mere Disaster. If we cut carbon emissions by half over the next decade, eliminate them entirely by 2050; if the species cuts its meat and dairy consumption by 90%; if we invent new unicorn technologies for sucking carbon back out of the atmosphere (or scale up extant prototype tech by a factor of two million in two years) — if we commit to these and other equally Herculean tasks, then we might just barely be able to keep global temperature from rising more than 1.5°C.[1] We’ll only lose 70-90% of the word’s remaining coral reefs (which are already down by about 50%, let’s not forget). Only 350 million more urban dwellers will be exposed to severe drought and “deadly heat” events. Only 130-140 million will be inundated. Global fire frequency will only increase by 38%. Fish stocks in low latitudes will be irreparably hammered, but it might be possible to save the higher-latitude populations. We’ll only lose a third of the permafrost. You get the idea.

We have twelve years to show results.

Not enough. Some countries that had it even ran from it recently (like Germany).

The updraft tower depending on configuration can transport large amount of dust upwards helping to create clouds, or condensate the moisture in the air (which is particularly effective in arid regions near the sea).

The balloon-solar plants would also help to reduce the temperature.
