By Jessica Corbett As the Trump administration charges forward with its war on science by canceling a “crucial” carbon monitoring system at NASA, scientists and climate experts are sounding alarms over atmospheric concentrations of carbon dioxide (CO2) that just surpassed a “troubling” threshold for the first time in human history. “The reading from the Mauna […]
Concentrations of atmospheric carbon dioxide (CO2) increased at “record-breaking” speed last year, according to the World Meteorological Organization’s (WMO) annual Greenhouse Gas Bulletin released Monday. According to the report, concentrations of CO2 reached 403.3 parts per million in 2016, up from 400.00 parts per million the year prior. This acceleration was due to a strong […]
By Alex Kirby Humanity has now entered a new climate reality era, with carbon dioxide concentrations expected to remain above the level of 400 parts per million throughout 2016 and for many generations to come, the World Meteorological Organization (WMO) said. The WMO—the United Nations system’s leading agency on weather, climate and water—said the globally […]
Life evolved to live within limits. It’s a delicate balance. Humans need oxygen, but too much can kill us. Plants need nitrogen, but excess nitrogen harms them and pollutes rivers, lakes and oceans. Ecosystems are complex. Our health and survival depend on intricate interactions that ensure we get the right amounts of clean air, water, […]
Carbon dioxide concentration in the atmosphere stayed above 400 parts per million (ppm) during September—a time when CO2 levels typically hit the yearly low—raising fears that the planet has reached a point of no return.

Fifteen mysterious bubbles have been discovered in Siberia. The mysterious bubbles produce a natural waterbed-like reaction when stepped on. Photo credit: Giphy Researchers Alexander Sokolov and Dorothee Ehrich, working on the island of Belyy, first spotted a mysterious bubble last year. While the exact reason for these spots hasn’t been determined, environmental researchers think they […]
Geographers in the U.S. have found a new factor in the carbon cycle, and—all too ominously—a new potential source of the greenhouse gas carbon dioxide (CO2). They have identified huge deposits of fossil soils, rich in organic carbon, buried beneath the Great Plains of America. Hidden menace: a vast store of organic carbon lies beneath the […]
