Methane is a powerful greenhouse gas that is second only to carbon dioxide in driving up global temperatures. But it doesn’t linger in the atmosphere for long thanks to molecules called hydroxyl radicals, which are […]

A new data visualization illustrates how an experimental NASA technology can provide extra lead time to communities in the path of a tsunami. Called GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network), the […]

The field of solar geoengineering revolves around the idea of cooling the globe via the injection of aerosols to reflect sunlight or to thin clouds. One such strategy, stratospheric aerosol injection (SAI), aims to mimic […]

This winter was one of the warmest on record across the West. As a result, many snowy, alpine areas have seen bouts of winter rainfall where there would ordinarily only be snow. These unusual weather […]

Green clay tennis courts are able to absorb massive amounts of carbon dioxide via enhanced rock weathering, according to a new study in Applied Geochemistry. Enhanced rock weathering—the process of using silicate rocks like basalt […]

Arctic rivers wind through remote tundra and boreal forests, freezing solid in winter and surging each spring with snowmelt, eventually emptying into the ocean. Runoff—water that does not soak into the ground but instead flows […]

The soil beneath our feet is a huge carbon bank storing up to approximately three times more carbon than the entire atmosphere. That makes it a significant player in the future of our climate. If […]

In Science of The Total Environment, researchers demonstrate the broad distribution of particulate thiols in the western North Pacific and show that their main source is marine phytoplankton. The analysis indicates that differences in thiol […]

Alaska’s glaciers respond to climate change by melting for three additional weeks with every 1 degree Celsius increase in the average summer temperature, data from satellite-mounted radars show.This post was originally published on this site

For half the world’s population, the water in their drinking glasses comes from below them. Groundwater also supplies 40% of global irrigation projects. Alarmingly, more than a third of the planet’s aquifers, or groundwater basins, […]
