"Exceeding 1.5°C global warming could trigger multiple climate tipping points - Climate tipping points are conditions beyond which changes in a part of the climate system become self-perpetuating. These changes may lead to abrupt, irreversible, and dangerous impacts with serious implications for humanity. Armstrong McKay et al. present an updated assessment of the most important climate tipping elements and their potential tipping points, including their temperature thresholds, time scales, and impacts. Their analysis indicates that even global warming of 1°C, a threshold that we already have passed, puts us at risk by triggering some tipping points. This finding provides a compelling reason to limit additional warming as much as possible."

"Observations have revealed that parts of the West Antarctic ice sheet may have already passed a tipping point. Potential early warning signals of the Greenland ice sheet, Atlantic Meridional Overturning Circulation, and Amazon rainforest destabilization have been detected. Multiple abrupt shifts have been found in climate models. Recent work has suggested that up to 15 tipping elements are now active."

"As resistance grows to the fossil fuel regime, laws are springing up everywhere to suppress climate activists - The climate crisis accelerates. Anti-protest laws proliferate. - These developments are not unrelated.

Why, despite all the warnings, does the world keep hurtling towards destruction? Well, the environmental economist Aviel Verbruggen estimates that the fossil fuel industry generated profits of US$2.8bn each and every day for the last 50 years.

You might have seen the new report by the World Meteorological Society, the one warning about humanity entering what UN secretary general António Guterres calls ‘“uncharted territory of destruction”. As emissions exceed pre-pandemic levels, the planet is now as likely as not to face temperatures more than 1.5C above pre-industrial measurements (the limit the UN COP26 summit pledged to avert) within the next five years.

A separate study in Science speculates that key ecological tipping points (including ice sheet collapses and the disruption of a major north Atlantic ocean current) may have already been passed.

The stakes could not be higher for the planet and its people. But they’re also immense for the corporate polluters, with the biggest companies collectively projected to develop new oil and gas fields to the tune of US$932bn by the end of 2030 – and an eye-popping US$1.5tn by 2040."
