Uh oh: Antarctica might melt much faster than we thought

Slate: Sea level rise--perhaps the most consequential effect of climate change--just got a whole lot more urgent. If you live near the coast, this is your wakeup call. In a study released Wednesday, a new estimate of how much Antarctic ice would melt in a warmer world nearly doubles previous projections of sea level rise by the end of the century. And it might be even worse than that: The study did not explore the true worst-case scenario, and its lead author said the work is still incomplete. Taken...
Barrier Reef at greater risk than thought: study

Agence France-Presse: Australia`s Great Barrier Reef, the world`s largest coral bank, is at greater risk than previously thought of dissolving as climate change renders the oceans more acidic, researchers warned recently. A decline in aragonite - the mineral that corals use to build their skeletons - is likely to accelerate, they found, as oceans absorb carbon dioxide spewed by mankind`s burning of fossil fuels. This disturbs ocean chemistry, leading to a drop in the pH level and less aragonite, a crystal form of...

Photosynthesis more ancient than thought, and most living things could do it
2016-03-16 04:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Photosynthesis is the process by which plants, algae and cyanobacteria use the energy from the Sun to make sugar from water and carbon dioxide, releasing oxygen as a waste product. But a few groups of bacteria carry out a simpler form of photosynthesis that does not produce oxygen, which evolved first. A new study by an Imperial researcher suggests that this more primitive form of photosynthesis evolved in much more ancient bacteria than scientists had imagined, more than 3.5 billion years ago....

This 2006 photo provided by the Centers for Disease Control and Prevention shows a female Aedes aegypti mosquito in the process of acquiring a blood meal from a human host. On Friday, Feb. 26, 2015, the U.S. government said Zika infections have been confirmed in nine pregnant women in the United States.
