"Shrinking goats" another indicator that climate change affects animal size
October 29, 2014 06:36 AM - Durham University

Alpine goats appear to be shrinking in size as they react to changes in climate, according to new research from Durham University. The researchers studied the impacts of changes in temperature on the body size of Alpine Chamois, a species of mountain goat, over the past 30 years.  To their surprise, they discovered that young Chamois now weigh about 25 per cent less than animals of the same age in the 1980s.

Adélie penguin chick weights correlated to temperatures

Oceanographers have reported a connection between local weather conditions and the weight of Adélie penguin chicks. Adélie penguins are an indigenous species of the West Antarctic Peninsula (WAP), one of the most rapidly warming areas on Earth. Since 1950, the average annual temperature in the Antarctic Peninsula has increased 2 degrees Celsius on average, and 6 degrees Celsius during winter.

As the WAP climate warms, it is changing from a dry, polar system to a warmer, sub-polar system with more rain.

MIT finds switching to higher octane fuel would reduce carbon emissions
October 28, 2014 07:15 AM - MIT News

If the majority of light-duty vehicles in the United States ran on higher-octane gasoline, the automotive industry as a whole would reduce its carbon dioxide emissions by 35 million tons per year, saving up to $6 billion in fuel costs, according to a new analysis by MIT researchers.

 

In a study published in the journal Environmental Science & Technology, the team considered a scenario in which fuel is manufactured under a redefined octane rating — the measure of a gasoline’s ability to resist engine knocking during combustion.

World losing 2,000 hectares of farm soil daily to salt damage
October 28, 2014 06:25 AM - United Nations University

Salt-spoiled soils worldwide: 20% of all irrigated lands — an area equal to size of France; Extensive costs include $27 billion+ in lost crop value / year. UNU study identifies ways to reverse damage, says every hectare needed to feed world’s fast-growing population. Every day for more than 20 years, an average of 2,000 hectares of irrigated land in arid and semi-arid areas across 75 countries have been degraded by salt, according to a new study — Economics of Salt-induced Land Degradation and Restoration — published today by the UNU Institute for Water, Environment and Health (UNU-INWEH).

Ocean Plays Important Role in Past Climate Change
October 27, 2014 08:35 AM - Rutgers University

Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. But in a new study published in Science, a group of Rutgers researchers have found that circulation of the ocean plays an equally important role in regulating the earth’s climate.

Abundant natural gas will not slow climate change according to new study
October 16, 2014 06:22 AM - Pacific Northwest National Laboratory

A new analysis of global energy use, economics and the climate shows that without new climate policies, expanding the current bounty of inexpensive natural gas alone would not slow the growth of global greenhouse gas emissions worldwide over the long term, according to a study appearing today in Nature Advanced Online Publication. Because natural gas emits half the carbon dioxide of coal, many people hoped the recent natural gas boom could help slow climate change — and according to government analyses, natural gas did contribute partially to a decline in U.S. carbon dioxide emissions between 2007 and 2012.

Could California Be Facing A Mega-Drought?
October 15, 2014 09:29 AM - Sonia Gadiaga, MONGABAY.COM

Agriculture, one of California’s strongest pillars, has taken the biggest hit: the drought will cost at least $2.2 billion in agricultural losses this year alone. Fields of dead almond trees and dried-out crops are a common sight in central California these days. Central Valley towns are also growing desperate. Many have been forced to install porta-potties in their backyards or even steal water from fire hydrants.
