Groundwater that has lingered in Earth’s depths for more than 12,000 years is surprisingly vulnerable to modern pollution from human activities. Once in place, that pollution could stick around for thousands of years, researchers report online April 25 in Nature Geoscience. Scientists previously assumed such deep waters were largely immune to contamination from the surface.
The world’s oceans are sweltering. Over the last century, marine heat waves have become more common and are lasting longer. New research suggests the annual number of days that some part of the ocean is experiencing a heat wave has increased 54 percent from 1925 to 2016, researchers report April 10 in Nature Communications.
The California Air Resources Board just announced that greenhouse gas pollution in California fell below 1990 levels for the first time since emissions peaked in 2004—an achievement roughly equal to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.
