Thick, impenetrable ice slabs are expanding rapidly on the interior of Greenland’s ice sheet, where the ice is normally porous and able to reabsorb meltwater. These slabs are instead sending meltwater spilling into the ocean, according to a new CIRES-led assessment, threatening to increase the country’s contribution to sea level rise by as much as … Read more
A new study has estimated for the first time how the eruption of Mount Tambora changed the probability of the cold and wet European ‘year without a summer’ of 1816. It found that the observed cold conditions were almost impossible without the eruption, and the wet conditions would have been less likely. 1816 recorded exceptionally … Read more
Communities across the United States are working with scientists to respond to climate change impacts, shows a new report and multimedia resources developed by the American Association for the Advancement of Science (AAAS). How We Respond shares details and perspectives from 18 communities using scientific information to adapt to climate change impacts and/or reduce greenhouse gas emissions. … Read more
Researchers from the University of Rennes 1 / CNRS (France), the University of Washington (USA) and the Universities of Yangon and Shwebo (Myanmar) have obtained new paleomagnetic evidence that the Burma Microplate was located close to the equator between 95 and 40 million years ago. These results, published in Nature Geoscience, support a double collision … Read more
The supply of dense Antarctic water from the bottom of the ocean to the Atlantic has declined in recent years. However, a new study explains for the first time how since 2014 this has stabilized and slightly recovered due to the variability in upstream dense waters, with implications for the global climate. The study, led … Read more
Newly digitized vintage film has doubled how far back scientists can peer into the history of underground ice in Antarctica, and revealed that an ice shelf on Thwaites Glacier in West Antarctica is being thawed by a warming ocean more quickly than previously thought. This finding contributes to predictions for sea-level rise that would impact … Read more
A new Columbia Engineering study indicates that the world will experience more frequent and more extreme drought and aridity than currently experienced in the coming century, exacerbated by both climate change and land-atmosphere processes. The researchers demonstrate that concurrent soil drought and atmospheric aridity are largely driven by a series of land-atmosphere processes and feedback … Read more
Elevated atmospheric carbon dioxide concentration increases land carbon sink, partially offsetting carbon dioxide emissions from human activities such as fossil fuel, cement production, and land-use change. This process is known as carbon dioxide fertilization, playing a key role in climate change mitigation and sustainable development of human society. Quantifying the carbon dioxide fertilization on the … Read more
The earliest large animal fossils lived in deep marine, oxygenated environments, now in central England (Leicestershire) and Newfoundland, following a cold spell about 575 million years ago, but within about 30-40 million years, the strange lifeforms gave way to more recognisable animals (worms, coral-like animals, sponges, etc.). What drove this change? A new UCL-led study … Read more
A day is the time for Earth to make one complete rotation on its axis, a year is the time for Earth to make one revolution around the Sun – reminders that basic units of time and periods on Earth are intimately linked to our planet’s motion in space relative to the Sun. In fact, … Read more
