Salt Marsh Carbon May Play Role in Slowing Climate Warming
Carbon dioxide is the predominant so-called “greenhouse gas” that acts as sort of an atmospheric blanket, trapping the Earth’s heat. Over time, an abundance of…
New Nature study illuminates 55 million years of the carbon cycle and climate history
Over this time period, when the Earth is known to have transitioned from “hothouse” to “icehouse” conditions, the oceans also experienced a dramatic shift in…
Tropical climate in the Antarctic: Palm trees thrived on today’s icy coasts 52 million years ago
Knowledge of past episodes of global warmth can be used to better understand the relationship between climate change, variations in atmospheric carbon dioxide…
Ancient Global Warming Allowed Greening of Antarctica
By examining the remnants of plant leaf wax found in sediment cores taken below the Ross Ice Shelf, scientists from the University of Southern California,…
Researchers Find Link Between the Input of Iron and Biological Productivity in the Ancient Pacific Ocean
The oceans are the world's largest inventory of reactive carbon. Over time, oceanic carbon exchanges with the atmospheric reservoir of carbon in the form of…
Injecting sulfate particles into stratosphere won't fully offset climate change
New University of Washington research demonstrates that one suggested method, injecting sulfate particles into the stratosphere, would likely achieve only part…
