Catastrophic climate 'doom loops' could start in just 15 years, new study warns
By Ben Turner published 2 days ago
Climate "tipping points," such as the loss of the Amazon rainforest or the collapse of the Greenland ice sheet, could come within a human lifetime, scientists have said.
Earth's ecosystems may be careering toward collapse much sooner than scientists thought, a new study of our planet's warming climate has warned.
According to the research, more than a fifth of the world's potentially catastrophic tipping points — such as the melting of the Arctic permafrost, the collapse of the Greenland ice sheet and the sudden transformation of the Amazon rainforest into savanna — could occur as soon as 2038.
In climatology, a "tipping point" is the threshold beyond which a localized climate system, or "tipping element," irreversibly changes. For instance, if the Greenland ice sheet were to collapse, it would also reduce snowfall in the northern part of the island, making large parts of the sheet irretrievable.

Why we must nationalize Big Oil
Excerpt:
Instead, it has used its influence and cash to sustain billions of dollars in annual taxpayer subsidies (nearly $6 trillion for fossil fuels in 2020) and cut-rate permits to extract oil and gas from public lands. For years, these practices suppressed the ability of clean substitutes like solar and wind energy to compete. More recently, the industry has opposed carbon pricing, which would correct market signals by better reflecting the actual social and environmental costs of carbon fuels.
