If despair is the most unforgivable sin, then hope is surely the most abused virtue. That observation feels particularly apposite as we enter the Cop season, that time of United Nations megaconferences at the end of every year, when national leaders feel obliged to convince us the future will be better, despite growing evidence to the contrary.
Small increase in temperature of intruding water could lead to very big increase in loss of ice, scientists say
The Global Tipping Points Report was launched at COP28 on 6 December 2023. The report is an authoritative assessment of the risks and opportunities of both negative and positive tipping points in the Earth system and society. Global Tipping Points is led by Professor Tim Lenton from the University of Exeter’s Global Systems Institute with the support of more than 200 researchers from over 90 organisations in 26 countries.
Collapse in system of currents that helps regulate global climate would be at such speed that adaptation would be impossible
Scientists now have a better understanding of the risks ahead and a new early warning signal to watch for.
This year's heat and drought in the Amazon intensify worries that it is approaching a tipping point.
Amazon rainforest and other ecosystems could collapse ‘very soon’, researchers warn
By replacing thousands of equations with just one, ecology modelers can more accurately assess how close fragile environments are to a disastrous “tipping point.”
Three “super-tipping points” for climate action could trigger a cascade of decarbonisation across the global economy, according to a report. Relatively small policy interventions on electric cars, plant-based alternatives to meat and green fertilisers would lead to unstoppable growth in those sectors, the experts said. But the boost this would give to battery and hydrogen production would mean crucial knock-on benefits for other sectors including energy storage and aviation.
Governments and businesses failing to change fast enough, says United in Science report, as weather gets increasingly extreme. Despite intensifying warnings in recent years, governments and businesses have not been changing fast enough, according to the United in Science report published on Tuesday. The consequences are already being seen in increasingly extreme weather around the world, and we are in danger of provoking “tipping points” in the climate system that will mean more rapid and in some cases irreversible shifts.
The Politics of the Anthropocene' is a sophisticated yet accessible treatment of how human institutions, practices, and principles need to be re-thought in response to the challenges of the Anthropocene, the emerging epoch of human-induced instability in the Earth system and its life-support capacities. The world remains stuck with practices and modes of thinking that were developed in the Holocene - the epoch of around 12,000 years of unusual stability in the Earth system, toward the end of which modern institutions such as states and capitalist markets arose....
