New NASA research on natural ozone cycles suggests ozone levels in the lowest part of Earth's atmosphere probably won't be affected much by projected future strengthening of the circulating winds that transport ozone between Earth's two lowest atmospheric layers.
A new analysis of NASA satellite data shows Africa's Congo rainforest, the second-largest tropical rainforest in the world, has undergone a large-scale decline in greenness over the past decade.
Researchers led by a Washington State University biologist have found that arid areas, among the biggest ecosystems on the planet, take up an unexpectedly large amount of carbon as levels of carbon dioxide increase in the atmosphere. The findings give scientists a better handle on the earth's carbon budget—how much carbon remains in the atmosphere as CO2, contributing to global warming, and how much gets stored in the land or ocean in other carbon-containing forms.
For the first time in more than a decade, five NASA Earth-observing missions will be launched into space in a single year. To celebrate this milestone, NASA is inviting people all around the world to step outside on Earth Day, April 22, take a "selfie," and share it with the world on social media.
Simply by breathing, humans have played a small part in the planet-wide balancing act called the carbon cycle throughout our existence. However, in the last few hundred years, we have taken a larger role. Our activities, such as fossil fuel burning and deforestation, are pushing the cycle out of its natural balance, adding more and more carbon dioxide to the atmosphere.
Verne Global, an innovative, UK-based developer of energy efficient data center campuses, today announced that the Proof of Concept (PoC) study they participated in with the Open Data Center Alliance (ODCA) has been recognized with an Environmental Leader Award for Top Project of the Year 2014.
While carbon dioxide is typically painted as the bad boy of greenhouse gases, methane is roughly 30 times more potent as a heat-trapping gas. New research in the journal Nature indicates that for each degree that the Earth's temperature rises, the amount of methane entering the atmosphere from microorganisms dwelling in lake sediment and freshwater wetlands — the primary sources of the gas — will increase several times.
Greenhouse gas (GHG) emissions must be reduced by 50-80 percent by 2050 to limit a global temperature increase of 2 degrees Celsius (or 3.6 degrees Fahrenheit). With vehicles as one of the prime producers, how can the transportation sector address that hurdle?
Results from a new study co-authored by Netra Chhetri, a faculty member at the Consortium for Science, Policy & Outcomes at Arizona State University, show global warming of only 2 degrees Celsius will be detrimental to three essential food crops in temperate and tropical regions. And beginning in the 2030s, yields from those crops will start to decline significantly.
New research led by the University of Exeter suggests that rising global temperatures will increase the quantity of the key greenhouse gas methane emitted from freshwater ecosystems to the Earth's atmosphere – which could in turn lead to further warming.
