Latest Methane Stories
While we learned earlier this year that 2012 was the ninth warmest year since 1880, this week we were greeted with news that greenhouse gases, like carbon dioxide, methane and nitrous oxide, hit record highs in that same year.
While scientists have known for several years that some mammals became smaller during a period of warming known as the Paleocene-Eocene Thermal Maximum, researchers have found a second instance of mammalian “dwarfing” attributable to increasing temperatures.
Traces of past microbial life in sediments off the coast of Peru document how the microbial ecosystem under the seafloor has responded to climate change over hundreds of thousands of years.
A team of Scandinavian scientists is warning that the tundra could be a significant contributor to greenhouse gas emissions if temperatures in the Arctic continue to rise.
The bottom of the deep sea is largely deserted. Oases occur for example at cold seeps where water transports dissolved elements from the seabed: Specialized microbes convert methane and sulfate from sea water to hydrogen sulfide releasing carbon dioxide.
Hydroxyl (OH) radicals – known as the detergent of the atmosphere – decompose isoprene in the air.
Uranus' moon Umbriel -- Umbriel is a moon of Uranus discovered in 1851 by William Lassell. It was named after the 'dusky melancholy sprite' in Alexander Pope's The Rape of the Lock. Umbriel's surface is the darkest of the Uranian moons, and it is also the least geologically active. It is mostly composed of water ice, with the balance made up of silicate rock and methane ice. Most of its methane ice is on its surface. ----- Discovery Discovered by William Lassell...
Uranus' moon Ariel -- Ariel is a moon of Uranus discovered in 1851 by William Lassell. Its composition is roughly 50% water ice, 30% silicate rock, and 20% methane ice, and it appears to have regions of fresh frost in places. Largely devoid of impact craters, Ariel appears to have undergone a period of intense geological activity that has produced a huge network of fault canyons and liquid water outflows over its surface. ----- Discovery Discovered by William Lassell...
