greenhouse gas bulletin
2014-09-09 07:28:44

Chuck Bednar for redOrbit.com - Your Universe Online Propelled by the largest single-year increase in carbon dioxide in three decades, the amount of greenhouse gases in the atmosphere reached record highs in 2013, the World Meteorological Organization (WMO) reported on Tuesday. According to the agency’s annual Greenhouse Gas Bulletin, there was a 34 percent increase in radiative forcing (the warming effect on our climate) due to CO2, methane and nitrous oxide. The report found that...

earth atmosphere ozone layer mystery
2014-09-08 05:20:11

Dr. Tony Phillips, Science@NASA High above Earth, more than 20 miles above sea level, a diaphanous layer of ozone surrounds our planet, absorbing energetic UV rays from the sun. It is, essentially, sunscreen for planet Earth. Without the ozone layer, we would be bathed in dangerous radiation on a daily basis, with side effects ranging from cataracts to cancer. People were understandably alarmed, then, in the 1980s when scientists noticed that manmade chemicals in the atmosphere were...

arctic permafrost
2014-08-25 03:00:15

Bernie DeGroat, University of Michigan Just how much Arctic permafrost will thaw in the future and how fast heat-trapping carbon dioxide will be released from those warming soils is a topic of lively debate among climate scientists. To answer those questions, scientists need to understand the mechanisms that control the conversion of organic soil carbon into carbon dioxide gas. Until now, researchers believed that bacteria were largely responsible. But in a study published in Science...

Stanford School of Engineering New study quantifies the degree of contribution to global climate caused by slash-and-burn agriculture and wildfires, and finds bigger than expected impact It has long been known that biomass burning – burning forests to create agricultural lands, burning savannah as a ritual , slash-and-burn agriculture and wildfires – figures into both climate change and public health. But until the release of a new study by Stanford University Civil and...

Gina Hebert, Marine Biological Laboratory What do mollusks, starfish, and corals have in common? Aside from their shared marine habitat, they are all calcifiers — organisms that use calcium from their environment to create hard carbonate skeletons and shells for stability and protection. The June issue of the Biological Bulletin, published by the Marine Biological Laboratory, addresses the challenges faced by these species as ocean composition changes worldwide. As atmospheric...

Carol Rasmussen, NASA Earth Science News Team NASA's Orbiting Carbon Observatory-2, which launched on July 2, will soon be providing about 100,000 high-quality measurements each day of carbon dioxide concentrations from around the globe. Atmospheric scientists are excited about that. But to understand the processes that control the amount of the greenhouse gas in the atmosphere, they need to know more than just where carbon dioxide is now. They need to know where it has been. It takes more...

OSU The oxygen-rich surface waters of the world’s major oceans are supersaturated with methane – a powerful greenhouse gas that is roughly 20 times more potent than carbon dioxide – yet little is known about the source of this methane. Now a new study by researchers at Oregon State University demonstrates the ability of some strains of the oceans’ most abundant organism – SAR11 – to generate methane as a byproduct of breaking down a compound for its phosphorus. Results...

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...
