California’s carbon mitigation efforts may be thwarted by climate change itself
Irvine, Calif., July 22, 2021 – To meet an ambitious goal of carbon neutrality by 2045, California’s policymakers are relying in part on forests and shrublands to remove CO2 from the atmosphere, but researchers at the University of California, Irvine warn that future climate change may limit the ecosystem’s ability to perform this service.

Climate change is driving plant die-offs in Southern California, UCI study finds
Irvine, Calif., June 21, 2021 – A shift is happening in Southern California, and this time it has nothing to do with earthquakes. According to a new study by scientists at the University of California, Irvine, climate change is altering the number of plants populating the region’s deserts and mountains. Using data from the Landsat satellite mission and focusing on an area of nearly 5,000 square miles surrounding Anza-Borrego Desert State Park, the research team found that between 1984 and 2017, vegetation cover in desert ecosystems decreased overall by about 35 percent, with mountains seeing a 13 percent vegetation decline.

UCI and international institutions link Southeast Asia megadrought to drying in Africa
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.

Greenhouse gas and particulate pollution emissions drive regional drying around the globe
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.

Know the risks of investing in forests
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.
