Several studies in recent years have suggested the crucial system — the Atlantic Meridional Overturning Circulation, or AMOC — could be on course for collapse, weakened by warmer ocean temperatures and disrupted saltiness caused by human-induced climate change. But the new research, which is being peer-reviewed and hasn’t yet been published in a journal, uses a state-of-the-art model to estimate when it could collapse, suggesting a shutdown could happen between 2037 and 2064.

Overexploitation and habitat loss pose extinction threats for migratory fish, birds and others, worldwide

The UN Secretary-General’s Early Warnings for All Initiative (EW4All) is rapidly gaining ground. Action plans are being rolled out around the world to ensure that people know when dangerous weather is headed their way. Tajikistan has held a two-day national consultation, co-chaired by the Deputy Prime Minister and the UN Resident Coordinator in Tajikistan, and bringing together key stakeholders from state and international organizations, media and civil society. Ethiopia also held an inception workshop.

A collapse would bring catastrophic climate impacts but scientists disagree over the new analysis

We investigate the potential implications of large language models (LLMs), such as Generative Pretrained Transformers (GPTs), on the U.S. labor market, focusing on the increased capabilities arising from LLM-powered software compared to LLMs on their own. Using a new rubric, we assess occupations based on their alignment with LLM capabilities, integrating both human expertise and GPT-4 classifications. Our findings reveal that around 80% of the U.S. workforce could have at least 10% of their work tasks affected by the introduction of LLMs, while approximately 19% of workers may see at least 50% of their tasks impacted. We do not make predictions about the development or adoption timeline of such LLMs. The projected effects span all wage levels, with higher-income jobs potentially facing greater exposure to LLM capabilities and LLM-powered software. Significantly, these impacts are not restricted to industries with higher recent productivity growth. Our analysis suggests that, with access to an LLM, about 15%

The Earth is approximately 1.1℃ warmer than it was at the start of the industrial revolution. That warming has not been uniform, with some regions warming at a far greater pace. One such region is the Arctic. A new study shows that the Arctic has warmed nearly four times faster than the rest of the world over the past 43 years. This means the Arctic is on average around 3℃ warmer than it was in 1980.

Since the beginning of March, India and Pakistan and large parts of South Asia experienced prolonged heat, that at the time of writing, May 2022, still hasn’t subsided.

A new survey from YouGov asked Americans for their thoughts on climate change, including what they believe its potential impacts could be and whether they believe they and their country are doing enough to tackle climate change. The findings suggest that most Americans anticipate dire consequences to climate change, but many believe there are still ways to avoid the worst of it.

Climate change has turbocharged severe storms, fires, hurricanes, coastal storms and floods — threatening millions

The Atlantic Meridional Overturning Circulation (AMOC), a major ocean current system transporting warm surface waters toward the northern Atlantic, has been suggested to exhibit two distinct modes of operation. A collapse from the currently attained strong to the weak mode would have severe impacts on the global climate system and further multi-stable Earth system components. Observations and recently suggested fingerprints of AMOC variability indicate a gradual weakening during the last decades, but estimates of the critical transition point remain uncertain.

In our latest study, scientists from France, Germany, Netherlands, and the UK collaborated to examine whether and to what extent human-induced climate change had a part to play in the cold early April following a very warm March 2021 that led to large scale frost damages in grapevines and fruit trees in central France.
