Neanderthals died out after Earth s magnetic poles flipped, causing a climate crisis 42,000 years ago, a study says

An exhibit shows a Neanderthal family at the Neanderthal Museum in Krapina, Croatia, in February 2010. Earth’s magnetic poles flipped 42,000 years ago, which may have triggered a global climate crisis, a new study found. The resulting changes in temperatures and radiation levels may have killed off many large mammals. The event may have ultimately contributed to the extinction of Neanderthals. Earth saw a lot of commotion when its magnetic poles flipped 42,000 years ago. Scientists have known about the flip since the late 1960s. Earth’s magnetic poles aren’t static – they’re generated by electric currents from the planet’s liquid outer core, which is constantly in motion. As of late, Earth’s magnetic North pole has wandered considerably on a path toward northern Russia.

New African groundwater maps reveal widespread resilience to climate change

19 February 2021 Reserves of groundwater in much of the populated parts of Africa are being replenished at rates that could help to protect communities against the damaging effects of climate change, finds a new study co-authored by UCL. Published in the journal Environmental Research Letters, the study has revealed that the long-term groundwater recharge (the rate at which groundwater is replenished) in Africa is approximately 15,000 cubic km per decade - enough to sustain widespread groundwater pumping for drinking water and irrigatation for farming. Made up of scientists from UCL, the British Geological Survey (BSG), and universities in Nigeria and South Africa, the research team found that recharge occurs even in drylands where groundwater is commonly the only perennial source of freshwater.
