Scientists at the US Department of Energy’s Lawrence Berkeley National Laboratory demonstrated the first direct observation of increased radiative forcing due to increased carbon dioxide levels in the atmosphere. This study, published in Nature , is the first to provide direct observational evidence linking rising carbon dioxide concentrations to the greenhouse effect.
Two previously unnoticed oceanic gateways of warm water have been linked to the extreme thinning of East Antarctica’s Totten Glacier according to new research from the University of Texas at Austin. This discovery raises concern for the state of the Antarctic ice sheet and rising sea levels.
Scientists at Florida State University are researching the fate of carbon released from during the thawing of long frozen permafrost soils in the arctic. According to their Geophysical Research Letter published this week, microorganisms are rapidly consuming the ancient carbon released from the permafrost, metabolizing it into carbon dioxide, and releasing it back into the environment. A dangerous cycle is underway whereby the regions of the Earth where permafrost is found continue to warm due to climate change and release more carbon which makes its way to the atmosphere as carbon dioxide via microorganisms and further contributes to climate change.
A new study from Dartmouth College suggests that the fate of the climate during the summer growing season in the U.S. Midwest remains uncertain as a potential consequence of climate change. The study was published in the journal Water Resources Research with collaboration from scientists at Columbia University, National University of Singapore, and Massachusetts Institute of Technology. The results are particularly alarming for the agricultural industry which is a critical component to the U.S. Economy and global food security.
Despite the widespread impression that in recent years there has been some respite and slowdown in climate change of the planet, in fact the aggravation of the problem continues uninterruptedly. This is the conclusion of a new US scientific research that challenges the estimates of the Intergovernmental Panel on Climate Change (IPCC), which, in 2013, had seen a "break" to climate change.
Satellites that monitor subtle changes in the Earth's gravitational field, show that the aquifers are over-pumped in many areas worldwide, without even knowing whether there are stocks or if water simply dries up.
