“Glaciers melting in Glacier National Park; Joshua trees dying in Joshua Tree National Park—and all these things are tied in to a changing climate,” according to Department of the Interior Secretary Sally Jewell. In an interview with USA Today, Jewell discusses how climate change is presenting challenges for managing national parks; can these national treasures be saved for future generations, or does limited money have to be spent elsewhere?
Annual precipitation and soil moisture in the Southwest U.S., and long-term variations such as drought, are largely driven by tropical Pacific and tropical North Atlantic sea-surface temperatures (SSTs), according to a new study published in Journal of Climate. Natural decadal variations in these SSTs have contributed to the dry regime the U.S. has experienced since early this century. The authors also found that naturally occurring droughts, mainly in the Southwest U.S., are becoming longer and more severe due to soil moisture depletion from human-induced climate change.
PLOS ONE has compiled several climate research articles from various disciplines, such as science policy and geoengineering, into a special collection focused on mitigating and adapting to the effects of climate change. The collection includes an article about climate change impacts on national parks in the U.S., in which the authors show the majority of parks have warmed significantly since 1901. Another article focuses on carbon offset projects, such as planting biodiverse native vegetation, and how they can benefit Indigenous Australian communities.
