Study: Weaker ocean circulation could enhance CO2 buildup in the atmosphere

As climate change advances, the ocean’s overturning circulation is predicted to weaken substantially. With such a slowdown, scientists estimate the ocean will pull down less carbon dioxide from the atmosphere. However, a slower circulation should also dredge up less carbon from the deep ocean that would otherwise be released back into the atmosphere. On balance, […]

Thawing permafrost: Not a climate tipping element, but nevertheless far-reaching impacts

June 3, 2024 - Permafrost soils store large quantities of organic carbon and are often portrayed as a critical tipping element in the Earth system, which, once global warming has reached a certain level, suddenly and globally collapses. Yet this image of a ticking timebomb, one that remains relatively quiet until, at a certain level […]

New animal study suggests potential long-term impact of global warming on sleep

The first of its kind study suggests that changing seasons and dramatic shifts in extreme weather conditions are likely to impact sleep patterns. Recent research indicates that the hotter summer temperatures potentially impair sleep quality, and therefore, overall health and wellbeing in wildlife. This research, published today in Proceedings of the Royal Society B, was […]

Understanding how wildfires change soil could aid recovery

Severe wildfires can drive chemical changes in soil that affect ecosystem recovery and risks to human health. A new study finds broader surveillance and modeling of these changes could inform strategies for protecting lives, property, and natural resources, and managing wildlife. The huge, long-lasting wildfires that have become increasingly common in recent years can cause […]

Overview article - Is the Atlantic Overturning Circulation Approaching a Tipping Point?

Studies show that the Atlantic Meridional Overturning Circulation (AMOC) has already weakened as a result of anthropogenic climate change and is possible moving towards a tipping point. This current has a significant influence on climate, particularly in Europe. Stefan Rahmstorf, head of the Earth System Analysis research department at the Potsdam Institute for Climate Impact […]

Discovery could end global amphibian pandemic

April 3, 2024 - A fungus devastating frogs and toads on nearly every continent may have an Achilles heel. Scientists have discovered a virus that infects the fungus, and that could be engineered to save the amphibians. The fungus, Batrachochytrium dendrobatidis or Bd, ravages the skin of frogs and toads, and eventually causes heart failure. To date […]

How NASA Spotted El Niño Changing the Saltiness of Coastal Waters

New findings have revealed a coastal realm highly sensitive to changes in runoff and rainfall on land. After helping stoke record heat in 2023 and drenching major swaths of the United States this winter, the current El Niño is losing steam this spring. Scientists have observed another way that the climate phenomenon can leave its mark on […]

A global map of how climate change is changing winegrowing regions

Grapes grown to make wine are sensitive to climate conditions such as temperature and extreme drought. These effects are already visible worldwide on yields, the composition of grapes and the quality of wines, with already and soon-to-be-observed consequences on the geography of wine production. Understanding shifts in wine production potential due to climate change is […]
