Irvine, Calif., Aug. 21, 2020 – Physical evidence found in caves in Laos helps tell a story about a connection between the end of the Green Sahara – when once heavily vegetated Northern Africa became a hyper-arid landscape – and a previously unknown megadrought that crippled Southeast Asia 4,000 to 5,000 years ago. In a paper published today in Nature Communications, scientists at the University of California, Irvine, the University of Pennsylvania, William Paterson University of New Jersey and other international institutions explain how this major climate transformation led to a shift in human settlement patterns in Southeast Asia, which is now inhabited by more than 600 million people.

Despite devastating impacts of drought on human and natural systems, the reasons why long-term regional drying occurs remain poorly understood.
Research led by Lawrence Livermore National Laboratory (LLNL) scientists have identified two signatures or “fingerprints” that explain why arid conditions are spreading worldwide, and why the Western United States has tended towards drought conditions since the 1980s while the African Sahel has recovered from its prolonged drought. The research appears in the July 6 edition of Nature Climate Change.
Using technology is essential for predicting tuber crop yields in drought-heavy regions
Some governments are counting on planted forests as offsets for greenhouse gas emissions—a sort of climate investment. But as with any investment, it’s important to understand the risks. If a forest goes bust, researchers say, much of that stored carbon could go up in smoke.
Forests can be best deployed in the fight against climate change with a proper understanding of the risks to that forest that climate change itself imposes.
