New study shows Arctic Ocean rapidly becoming more corrosive to marine species
New research by NOAA, University of Alaska, and Woods Hole Oceanographic Institution in the journal Oceanography shows that surface waters of the Chukchi and Beaufort seas could reach levels of acidity that t ...
Researchers predict gradual, prolonged release of greenhouse gases from thawing permafrost
There's qualified good news about one contributor to climate change, say researchers who have crunched data from a series of recent studies.
Researchers find less expensive way to convert carbon dioxide
With an abundance of carbon dioxide being produced worldwide, scientists and engineers are looking for inexpensive ways to turn it into something useful, such as hydrocarbon fuels.
Plowing prairies for grains: Biofuel crops replace grasslands nationwide
Clearing grasslands to make way for biofuels may seem counterproductive, but University of Wisconsin-Madison researchers show in a study today (April 2, 2015) that crops, including the corn and soy commonly ...
Optics, nanotechnology combined to create low-cost sensor for gases
Engineers have combined innovative optical technology with nanocomposite thin-films to create a new type of sensor that is inexpensive, fast, highly sensitive and able to detect and analyze a wide range of ...
Greatest mass extinction driven by acidic oceans, study finds
Changes to the Earth's oceans, caused by extreme volcanic activity, triggered the greatest extinction of all time, a study suggests.
Climate scientists find elusive tropospheric hot spot
Researchers have published results in Environmental Research Letters confirming strong warming in the upper troposphere, known colloquially as the tropospheric hotspot. The hot has been long expected as par ...
Global carbon dioxide levels reach new monthly record (Update)
In another ominous sign of human-caused climate change, US government scientists said Wednesday that global carbon dioxide concentrations have reached a new monthly record of 400 parts per million.
Startup turns old shipping containers into farms
The food tech startup Freight Farms is giving new life to old shipping containers, and at the same time giving impetus to locally grown food.
Human security at risk as depletion of soil accelerates, scientists warn
Steadily and alarmingly, humans have been depleting Earth's soil resources faster than the nutrients can be replenished. If this trajectory does not change, soil erosion, combined with the effects of climate ...
Anesthetic gases raise Earth's temperature (a little) while you sleep
The gases used to knock out surgery patients are accumulating in the Earth's atmosphere, where they make a small contribution to climate change, report scientists who have detected the compounds as far afield ...
Photosynthesis hack needed to feed the world by 2050, report says
Using high-performance computing and genetic engineering to boost the photosynthetic efficiency of plants offers the best hope of increasing crop yields enough to feed a planet expected to have 9.5 billion ...
Rising carbon dioxide levels stunt sea shell growth
Scientists have discovered that stunted growth can be a genetic response to ocean acidification, enabling some sea creatures to survive high carbon dioxide levels, both in the future and during past mass ...
Study backs seaweed's carbon capturing potential
There are great hopes for the potential of coastal plants and seaweeds to store carbon and help counter the effects of climate change and a new study is backing that potential.
