New insights into global ocean microbe-virus interactions, drivers of Earth's ecosystems
2015-05-21 12:00:00| LifeSciencesWorld
[NEWS] Hidden among Earth's vast oceans are some of the tiniest and most vital organisms to the health of delicate ecosystems. Ocean microbes produce half of the oxygen we breathe, and are important drivers in chemical reactions and energy transfers that fuel critical ecological processes. Much like other organisms, marine microbes are susceptible to viral infections that can alter their metabolic output, or even kill them. For example, certain ocean viruses invade algae and tak…

We're burning through the Earth's carbon budget
2015-05-12 16:38:00| Climate Ark Climate Change & Global Warming Newsfeed
CNN: Here's a recent headline that sends chills down your spine if you're a climate-news junkie -- and makes just about zero sense if you're any other normal person: "A Global Milestone: CO2 Passes 400 PPM" Translation: There's now an even more ridiculous amount of carbon dioxide in the atmosphere -- 400 parts carbon dioxide (CO2) for every million parts of something else atmospheric. That's warming the planet. And it's our fault since we're burning fossil fuels and clearing forests. But that's...

Earth's cloudy demeanour unveiled by NASA's Aqua satellite
2015-05-11 20:01:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: Waiting for the sun to come out? It might be unwise to hold your breath. Earth is generally a cloudy place, according to this map. NASA's Aqua satellite has built up this average view of Earth's surface by monitoring global cloud cover every day since 2002. Cloud-free areas are dark blue, lighter shades represent more cloud cover, and the most overcast areas are white. The map reveals three particularly cloudy bands. A white strip runs close to the equator while two wider bands run roughly...

Acidic oceans implicated in Earth's worst mass extinction
2015-04-09 20:20:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: It is one of science's enduring mysteries: what caused the worst mass extinction in Earth's history. And, no, it is not the one that wiped out the dinosaurs. Scientists said on Thursday that huge amounts of carbon dioxide spewed from colossal volcanic eruptions in Siberia may have turned the world's oceans dangerously acidic 252 million years ago, helping to drive a global environmental calamity that killed most land and sea creatures. The researchers studied rocks in the United Arab Emirates...
