'Devastating' melt of Greenland, Antarctic ice sheets found

The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago

the planet has accumulated as much heat in the past 15 years as it did in the previous 45 years, the majority of the excess heat has been absorbed by the oceans

A technical chart in a chapter of the latest UN climate assessment laid out the unfathomable heat gain. Between 1971 and 2018, the ocean had gained 396 zettajoules of heat.

How much heat is that? Scientists have calculated it is the equivalent energy of more than 25bn Hiroshima atomic bombs. And that heat gain is accelerating.

A study in January found the ocean gained 10 ZJ more in 2022 than the year before – enough heat to boil 700m kettles every second.

"I conducted a data update to Limits to Growth (LtG), best known from the 1972 bestseller that forecasted a scenario of global societal collapse occurring around the present time if humanity did not alter its priorities. Empirical data comparisons since then indicated that the world was still heading for collapse. ... I found that the scenarios aligned closely with observed global data, which is a testament to the LtG work done decades ago. The two scenarios aligning most closely indicate a halt in growth over the next decade or so, which puts into question the usability of continuous growth as humanity’s goal in the 21st century. Both scenarios also indicate subsequent declines, but only one—the scenario in which declines are caused by pollution, including greenhouse gas pollution—depicts a collapse pattern. The scenario with the smallest declines aligned least with empirical data, however, absolute differences were rarely big and sometimes insignificant. This suggests that it’s almost, but not yet, too late for society to change course."

"We unravel the arguments that have raged for forty years in its aftermath and explore more recent findings which relate to the original hypothesis. There is unsettling evidence that society is still following the ‘standard run’ of the original study – in which overshoot leads to an eventual collapse of production and living standards. Detailed recent studies suggests that production of some key resources may only be decades away. Certain other limits to growth – less visible in the 1972 report – present equally pressing challenges to modern society. We highlight, in particular, recent work on our proximity to ‘planetary boundaries’ and illustrate this through the challenge of meeting the Paris Agreement on climate change. We also explore the economic challenge of a ‘secular stagnation’. If the Club of Rome is right, the next few decades are decisive."
