The world's mussel population could be under threat as rising CO2 levels in atmosphere and oceans makes their shells weaker and more brittle shells - making them more vulnerable to stormy seas, and predation.

Renewables Dominate New US Electrical Generating Capacity
According to the latest “Energy Infrastructure Update” report from the Federal Energy Regulatory Commission’s (FERC) Office of Energy Projects, wind energy and solar power combined provided over 70 percent (71.82%) of the 873 megawatts (MW) of new U.S. electrical generating capacity placed into service in November 2014. Specifically, three wind farms came on line last month, accounting for 333-MW of new generation in service. These included Stella Wind Farm’s 182-MW Panhandle Wind Farm Phase II expansion in Texas and the 150-MW Origin Wind Energy project in Oklahoma. New wind generating capacity this year thus far has more than doubled that for the same period in 2013 (2,525-MW vs. 1,112-MW).
How the Credit Card Industry is Contributing to Pollution
We all get far too much mail, especially from financial services companies. Credit card companies alone send billions of pieces of paper mail each year, and most of that gets thrown right into the trash can. Not only does this dynamic pose a threat from a fraud perspective – trash cans and mailboxes can be treasure troves for opportunistic fraudsters – but you have to figure the effect on the environment isn’t great either. Paper products aren’t as bad as most materials, according to North Carolina State University Professor Richard Venditti, because they’re renewable, recyclable and biodegradable and they motivate land owners to plant trees. However, Venditti says, “inefficient use of paper does consume resources and have an impact on the environment.” While credit card direct mail is on the rise after hitting a two-year low in April 2012, long-term trends suggest a declining role for traditional paper mail in the years to come. Not only are financial services companies increasingly offering paperless options to their account holders – even charging extra for paper statements, but they’re also learning how to better leverage digital means for marketing purposes. These changes are largely based on the shifting preferences of the modern consumer as well as the overall technicalization of modern commerce – not some newfound corporate altruism – but does it really matter?
Temperature rise in Finland outpaces global average
Over the past 166 years, the average temperature in Finland has risen by more than two degrees. During the observation period, the average increase was 0.14 degrees per decade, which is nearly twice as much as the global average.
According to a recent University of Eastern Finland and Finnish Meteorological Institute study, the rise in the temperature has been especially fast over the past 40 years, with the temperature rising by more than 0.2 degrees per decade. "The biggest temperature rise has coincided with November, December and January. Temperatures have also risen faster than the annual average in the spring months, i.e., March, April and May. In the summer months, however, the temperature rise has not been as significant," says Professor Ari Laaksonen of the University of Eastern Finland and the Finnish Meteorological Institute. As a result of the temperature rising, lakes in Finland get their ice cover later than before, and the ice cover also melts away earlier in the spring. Although the temperature rise in the actual growth season has been moderate, observations of Finnish trees beginning to blossom earlier than before have been made.
Southern Glaciers in China are Melting
Glaciers in China that are a critical source of water for drinking and irrigation in India are receding fast, according to a new comprehensive inventory. In the short term, retreating glaciers may release greater meltwater, “but it will be exhausted when glaciers disappear under a continuous warming,” says Liu Shiyin, who led the survey for the Cold and Arid Regions Environmental and Engineering Research Institute in Lanzhou.
Do Weddell Seals have an Internal GPS?
Weddell seals have biological adaptations that allow them to dive deep--as much as of hundreds of meters--while hunting, but also an uncanny ability to find the breathing holes they need on the surface of the ice. Now, researchers supported by the National Science Foundation (NSF) believe they have figured out how they do it--by using the Earth's magnetic field as a natural GPS. "This animal, we think, may be highly evolved with an ability to navigate using magnetic sense in order to find ice holes some distance apart and get back to them safely," explained Randall Davis of the Department of Marine Biology at Texas A&M University. If the hypothesis turns out to be true, it would represent the first evidence of such a trait in a marine mammal.
