‘The only uncertainty is how long we’ll last’: a worst case scenario for the climate in 2050 | Environment | The Guardian
Fewer people work outdoors and even indoors the air can taste slightly acidic, sometimes making you feel nauseated. The last coal furnaces closed 10 years ago, but that hasn’t made much difference in air quality around the world because you are still breathing dangerous exhaust fumes from millions of cars and buses everywhere. Our world is getting hotter. Over the next two decades, projections tell us that temperatures in some areas of the globe will rise even higher, an irreversible development now utterly beyond our control. Oceans, forests, plants, trees and soil had for many years absorbed half the carbon dioxide we spewed out. Now there are few forests left, most of them either logged or consumed by wildfire, and the permafrost is belching greenhouse gases into an already overburdened atmosphere. The increasing heat of the Earth is suffocating us and in five to 10 years, vast swaths of the planet will be increasingly inhospitable to humans. We don’t know how hospitable the arid regions of Australia, South Africa and the western United States will be by 2100. No one knows what the future holds for their children and grandchildren: tipping point after tipping point is being reached, casting doubt on the form of future civilisation. Some say that humans will be cast to the winds again, gathering in small tribes, hunkered down and living on whatever patch of land might sustain them.

One-third of plant and animal species could be gone in 50 years, study says
Previous studies have focused on dispersal—or migration to cooler habitats—as a means for species to "escape" from warming climates. However, the authors of the current study found that most species will not be able to disperse quickly enough to avoid extinction, based on their past rates of movement. Instead, they found that many species were able to tolerate some increases in maximum temperatures, but only up to a point. They found that about 50% of the species had local extinctions if maximum temperatures increased by more than 0.5 degrees Celsius, and 95% if temperatures increase by more than 2.9 degrees Celsius.

"Capitalism is at the heart of the climate challenge."
No, no, no.
(1) Look at the environmental record of the USSR, or of pre-Deng China. Soviet Earth would be facing ~ as big a climate crisis as Neoliberal Earth (only with Comrade Mann in the roll of Sakharov at best).
(2) Maintaining our _current_ sized economies _without current technologies_ would get us cooked, so it's not _economic growth_ that's the problem.

Purdy knows better.
