For a long time, tropical forests have acted as a carbon sink, taking more carbon out of the air than they release into it, a process that has moderated the impact of climate change. But new research found that in 2015 -- 2016, when an El Niño climate event resulted in drought and the hottest temperatures ever recorded, South American forests were unable to function as a carbon sink.

Yet less than 20% of croplands are equipped for irrigation. A new study finds that by the middle of the 21st century under a moderate greenhouse gas emissions scenario, the benefits of expanded irrigation will outweigh the costs of installation and operation over an expanded portion of current U.S. croplands. The study maps where it makes the most sense to install irrigation for corn and soybeans and if there's enough water to do so.

These cloud-to-ground strikes during little to no rainfall were previously thought to pose wildfire danger only if occurring with less than 2.5 mm of rain in a day (about 0.10 inches). A new study of lightning-ignited wildfires in the U.S. West found the strikes caused wildfires despite up to 7.7 mm (about 0.3 inches) of precipitation. While still a low amount of rain, the more accurate estimation could help responders detect fires earlier, especially those known as 'holdovers,' which can smolder for many days before exploding into full-blown wildfires.

Overall, continental water volumes vary so much over time that global sea levels fluctuate significantly too. By combining the hydrological model WaterGAP with GRACE satellite data, a team of geodesists have come up with a new set of data that shows how the total distribution of water over the Earth's land surfaces has changed over the past 20 years more accurately than ever before.

This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.
