NASAs Mars 2020 rover will hunt for signs of alien life, produce oxygen from Mars atmosphere
2014-08-01 13:48:42| Extremetech
NASA has announced that the next Mars rover -- currently codenamed Mars 2020 -- will be outfitted with an array of sophisticated, upgraded scientific instruments that will let it delve deeper and farther than Curiosity, with the hope that it will be able to uncover signs of life on Mars. Perhaps even more excitingly, Mars 2020 will also be equipped with a new instrument that can convert the carbon dioxide in Mars' atmosphere into oxygen -- this is of utmost importance if humanity ever colonizes Mars -- and another instrument that will gather and store Martian rock samples for eventual return to Earth.
Earth's breathable atmosphere tied to plate tectonics?

PhysOrg: The rise of oxygen is one of the biggest puzzle in Earth's history. Our planet's atmosphere started out oxygen-free. Then, around 3.5 billion years ago, tiny microbes called cyanobacteria (or blue-green algae) learned out to carry out photosynthesis. They began using energy from sunlight to make their food from carbon dioxide and water, giving off oxygen as waste. But it took another 3 billion years for oxygen levels to climb from trace amounts to at least 20 percent of the atmosphere, or high...

How Do Pollen Particles In The Atmosphere Influence Climate?

RedOrbit: Researchers study water cycle and cloud formation and design computer algorithm models to understand impact In the past, many atmospheric scientists believed that pollen particles probably had a negligible effect on climate because they were so big. In recent years, however, as they began to realize that pollen particles were not as sturdy as they once thought, they have been rethinking their old assumptions. Pollen can rupture and generate a lot of small, tiny particles, says Allison Steiner,...

Frackers are flooding the atmosphere with climate-warming methane
2014-05-13 01:47:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: The free pass that frackers and natural-gas handlers have gotten on their climate-changing methane emissions is really starting to stink to high hell. We told you in February about the results of a meta-analysis of 20 years worth of scientific studies, which concluded that the EPA underestimates the natural-gas industry`s climate impacts by 25 to 75 percent, due to methane leakage from its gas drilling operations and pipelines. Methane, the main component of natural gas, is a potent greenhouse...
