NASA maps CO2 emissions over the entire planet
December 25, 2014 11:39 AM - BRIAN KAHN, CLIMATE CENTRAL, via DiscoveryNews

It’s been a busy five months for NASA’s newest carbon dioxide-monitoring satellite, snapping up to 1 million measurements a day of how carbon dioxide moves across the planet. Now NASA scientists have shared the first global maps created using that data, showing one of the most detailed views of CO2 ever created.

The satellite — known as OCO-2 — has been in orbit since July. While it’s returned some preliminary data, NASA showed off its global reach for the first time on Thursday at the annual American Geophysical Union meeting.

Carbon Dioxide Threat To Mussels' Shells

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
December 24, 2014 10:01 AM - Clean Techies Staff, Clean Techies

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).

Temperature rise in Finland outpaces global average
December 24, 2014 09:13 AM - University of Eastern Finland via ScienceDaily

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.

Do Weddell Seals have an Internal GPS?
December 23, 2014 01:15 PM - National Science Foundation

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.

Southern Glaciers in China are Melting
December 23, 2014 09:14 AM - Christina Larson, Science/AAAS

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.

Fireplace and wood stove tips for a cleaner burn from EPA
December 23, 2014 08:23 AM - US Environmental Protection Agency

Across the country this holiday season, families and friends will gather around fires in woodstoves or fireplaces. But how you build that fire – and what you burn – can have a significant impact on air quality and health, both inside your home and out.

Whether you’re using a woodstove, pellet stove, or your fireplace, seeing smoke from your chimney means your fire isn’t burning efficiently or cleanly as it could. 

Woodsmoke contains fine particles – also called fine particle pollution or PM2.5 -- which can harm the lungs, blood vessels and heart. People with heart, vascular or lung disease, and older adults and children are more at risk. 

Here are some simple tips for building cleaner-burning fires this holiday season:
