| Antarctic ice-sheet destabilized within a decade Posted: 18 Nov 2021 05:37 PM PST After the natural warming that followed the last Ice Age, there were repeated periods when masses of icebergs broke off from Antarctica into the Southern Ocean. A new data-model study now shows that it took only a decade to initiate this tipping point in the climate system, and that ice mass loss then continued for many centuries. |
| Rivers play key role in destructive coastal flooding, new research shows Posted: 18 Nov 2021 05:37 PM PST Rising oceans get more attention in climate change discussions, but rivers are rising, too, according to new research by a University of South Carolina postdoctoral fellow. The research shows that rivers need more attention in policy management and disaster preparation, both at the coast and farther inland. |
| Speeding up the energy transition reduces climate risks Posted: 18 Nov 2021 05:37 PM PST The World Climate Conference in Glasgow has just ended, and the question is whether the goal of maximum global heating of 1.5°C can still be achieved. In a model calculation, researchers show how the energy transition could lead to the lowest possible cumulative emissions: Instead of slowly cutting back emissions, we should quickly push ahead with the conversion to solar energy and use fossil power plants at full capacity for one last time to do so. |
| Posted: 18 Nov 2021 05:37 PM PST The most comprehensive survey conducted of elephant numbers in the Central African nation of Gabon since the late 1980s has found elephants occurring in higher numbers than previously thought. |
| Macrogrid study: Big value in connecting America’s eastern and western power grids Posted: 18 Nov 2021 05:37 PM PST A 'macrogrid' that increases the electricity moving between America's Eastern and Western interconnections, two of the biggest power grids on the planet, would more than pay for itself, according to new research. |
| Bubbling up: Previously hidden environmental impact of bursting bubbles exposed in new study Posted: 18 Nov 2021 05:36 PM PST Bubbles are common in nature and can form when ocean waves break and when raindrops impact surfaces. When bubbles burst, they send tiny jets of water and other materials into the air. A new study examines how the interplay between bubble surfaces and water that contains organic materials contributes to the transport of aerosolized organic materials -- some of which are linked to the spread of disease or contamination -- into the atmosphere. |
| Extreme heat events jeopardize cardiovascular health, experts warn Posted: 18 Nov 2021 03:16 AM PST A consequence of global warming is a greater frequency and intensity of extreme heat events. This extreme heat is associated with a greater risk of adverse cardiovascular incidents, especially for adults with pre-existing cardiovascular diseases. |
| Woodland and hedgerow creation can play crucial role in action to reverse declines in pollinators Posted: 16 Nov 2021 05:15 PM PST The largest survey of pollinator abundance in Wales has found that woodland and hedgerow creation can play a crucial role in action to reverse declines in insects that are essential for crop yield and other wildlife. |
