Tropical forests in South America lose their ability to absorb carbon from the atmosphere when conditions become exceptionally hot and dry, according to new research. For a long time, tropical forests have acted as a carbon sink, taking more carbon out of the air than they release into it, a process that has moderated the...
Giant dust storms in the Gulf of Alaska can last for many days and send tonnes of fine sediment or silt into the atmosphere, and it is having an impact on the global climate system, say scientists. The storms are so extensive they can be seen by satellites orbiting the Earth. An image captured by...
One of the biggest obstacles to the uptake of plant-based alternatives to meat is their dry and astringent feel when they are eaten. Scientists, led by Professor Anwesha Sarkar at the University of Leeds, are revolutionising the sensation of plant proteins, transforming them from a substance that can be experienced as gloopy and dry to...
Mountain treelines, which mark the upper limit for tree growth in high-altitude areas, are shifting as a result of climate change, say researchers. The researchers, led by a scientist at the University of Leeds, used satellite images to develop an algorithm that detects nearly one million kilometres of closed-loop treelines across 243 mountain ranges. Closed-loop...
With world attention on recent wildfires and floods in North America, Europe and China, people should not overlook the devastating impact of climate change in Antarctica, scientists have warned. Antarctica, a cold and remote continent in the southern hemisphere, is composed of “fragile and vulnerable environments” which may be subject to considerable stress and damage...
