Solar a Better Investment Than Stocks in Most Large U.S. Cities, Study Says

Yale Environment 360: For homeowners in 46 of the 50 largest cities in the U.S., investing in a residential solar power system would yield better returns than putting money in the stock market, according to an analysis by the North Carolina Clean Energy Technology Center at North Carolina State University. For 21 million owners of single-family homes in the U.S., solar energy already costs less than current local utility rates, the report says, as long as the system can be purchased with low-cost financing of 5 percent...
The rate of sea-level rise is far worse previously thought, study says

Washington Post: Researchers have come up with a new and improved way of measuring the rise in the sea level, and the news is not good: The seas have risen dramatically faster over the last two decades than anyone had known. For hundreds of years, the seas were measured by more or less the equivalent of plopping a yard stick into the ocean and seeing if the ocean went up or down. But now, that method looks to be outdated. According to a new study published on Wednesday in Nature, the new method involves an...
Study says sea levels rising quicker than thought

Deutsche-Welle: US researchers have used probability theory to calculate that the global mean sea level rose slower throughout most of the 20th century than previously thought. But more recently, it may be rising faster. A new study helps clarify the mystery of why the sea levels seem to have risen faster than was expected during most of the 20th century. So far, researchers assumed that worldwide, the oceans have been rising constantly by 1.6 to 1.9 millimeters per year. But this was far more than could be...

Humans push planet beyond boundaries towards "danger zone"- study

Climate change, biodiversity loss, changes in land use, and altered biogeochemical cycles due in part to fertiliser use have fundamentally changed how the planet functions, the study said.

Ocean Life Faces Mass Extinction, Broad Study Says
2015-01-16 11:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: A team of scientists, in a groundbreaking analysis of data from hundreds of sources, has concluded that humans are on the verge of causing unprecedented damage to the oceans and the animals living in them. We may be sitting on a precipice of a major extinction event, said Douglas J. McCauley, an ecologist at the University of California, Santa Barbara, and an author of the new research, which was published on Thursday in the journal Science. But there is still time to avert catastrophe, Dr. McCauley...
