Scientists discovered an ancient river landscape preserved under the East Antarctic Ice Sheet

Global warming could reveal an ancient river landscape buried beneath the East Antarctic Ice Sheet for a million years, according to a study. The author of the study and who researches ice sheet behavior at Durham University in the UK, Stewart Jamieson, told ABC News that for about 34 million years, ice has covered Antarctica. Before that, the continent had a comparatively warm climate similar to modern-day southern South America, such as the Patagonia region in Argentina and Chile.

At least 100 elephants die in drought-stricken Zimbabwe park, a grim sign of El Nino, climate change

Image
Climate change and the El Nino weather phenomenon have caused the deaths of at least 100 elephants in Zimbabwe's Hwange National Park. The Zimbabwe National Parks and Wildlife Management Authority warns that more elephants could die due to the scarcity of rains and rising heat. The International Fund for Animal Welfare describes this situation as a crisis for elephants. Climate change may be making El Ninos stronger, leading to more extreme consequences. In 2019, over 200 elephants died in Hwange due to severe drought. from Environment News, Earth News, Global Warming, Wild Life, Carbon Trading, Climate Business, Climate Change & Pollution News https://ift.tt/UJnreu7 via IFTTT
