Snowcapped mountains not only look majestic, they are vital to a delicate ecosystem that has existed for tens of thousands of years. Mountain water runoff and snowmelt flows down to streams, rivers, lakes, and oceans and today around a quarter of the world depends on these natural “water towers” to replenish downstream reservoirs and groundwater aquifers for urban water supplies, agricultural irrigation, and ecosystem support.
The world’s current climate pledges are insufficient to keep the goal of the 2015 Paris Agreement firmly within grasp. Global warming will likely surpass the 1.5-degree Celsius limit.
As climate change worsens water quality and threatens ecosystems, the famous dams of beavers may help lessen the damage.
The National Oceanic and Atmospheric Administration has awarded Oregon State University and its research partners $4.2 million to investigate how multiple climate change-related stressors are impacting marine ecosystems off the coast of Oregon, Washington and Northern California.
California state scientists have released a new report that shows how the impacts of climate change are rapidly accelerating in California. Key findings illustrate an exponential increase in wildfires and point to a hotter, drier environment driven by megadrought. Climate-influenced changes in freshwater and ocean conditions, says the report, are threatening the survival of Chinook salmon in Northern California rivers.
A UCLA-led study published this week reveals that migratory birds across North America are getting smaller, a change the researchers attribute to the rapidly warming climate.
Conservationists filed a formal notice this week of their intent to sue the U.S. Fish and Wildlife Service for once again denying Montana’s Arctic grayling population Endangered Species Act protections. Arctic grayling is a freshwater fish in the same family (Salmonidae) as salmon, trout, and whitefish.
The U.S. Fish and Wildlife Service has finalized protections for the emperor penguin, a flightless seabird endemic to Antarctica, under the Endangered Species Act. The emperor penguin is listed as a threatened species and includes a section 4(d) rule that tailors protections for the species. The impact of climate change on sea-ice habitat, where the species spends the majority of its life, is the primary threat to the penguin.
Narwhals are changing their migration patterns in response to pressure from changing Arctic climates, a new University of British Columbia report has found.
