Mountain Thermostats
March 17, 2014 08:10 AM - Dominic Rowland, MONGABAY.COM

What do mountains have to do with climate change? More than you'd expect: new research shows that the weathering rates of mountains caused by vegetation growth plays a major role in controlling global temperatures. Scientists from the University of Oxford and the University of Sheffield have shown how tree roots in certain mountains "acted like a thermostat" for the global climate. In warmer climates, tree roots grow faster and deeper (aided by the decomposition of leaf litter), breaking up rock that combines with carbon dioxide. This weathering process removes carbon dioxide from the atmosphere, lowering the global temperature and decreasing the growth rate of vegetation.

A global climate change directive?
March 14, 2014 04:11 PM - Editor, ENN

Could another climate change deal be in the works? World leaders are meeting in Brussels this month to discuss climate change. While environmentalists are calling for urgent action to cut greenhouse gas emissions, diplomatic language presented in the introductory document is most likely not ambitious enough.

Can Penguins Cope with Climate Change?

Human-caused climate change is altering the habitat of Adélie penguins (Pygoscelis adeliae). In an article recently published in PLOS ONE, a team of researchers led by Amélie LescroĆ«l from the Centre d'Ecologie Fonctionnelle et Evolutive (CNRS) in France, found that changes in sea-ice content and newly formed icebergs significantly impacted Adélie penguin communities in the Ross Sea.

Antarctic ecosystem due to change radically with climate change

According to researchers the Ross Sea will "be extensively modified by future climate change" in the coming decades creating longer periods of ice-free open water and affecting life cycles of all components of the ecosystem in a paper published and funded by the National Science Foundation (NSF). The researchers have drawn their information from the Regional Ocean Modeling System, a computer model that evaluates sea-ice, ocean, atmosphere and sea-shelf.

Warmer years linked to more malaria in tropical highlands

[BOGOTA] People in densely populated highlands of Africa and South America — who have so far been protected from malaria by cooler temperatures — may be seeing more of the disease as the climate changes, according to a study in Science (6 March).

Rooftop considerations amidst climate change
March 13, 2014 11:54 AM - Robin Blackstone, ENN

As the realities of climate change set in, so too are realizations that building technologies impact both internal and external environments. The percentage increase of asphalt and blacktopped roofs create urban heat islands. Resultantly cities have become earth's newest desserts exhibiting high temperatures and arid conditions with little vegetation. Urban expansion as a stand-alone factor (omitting greenhouse gas-induced climate change considerations) is expected to raise temperatures by roughly six degrees. Because of this, scientists are now exploring new technologies to cope with the new reality.

Big Ben May Get a Solar Face Lift

In an effort by the U.K. Parliament to reach the ambitious goal of reducing greenhouse gas emission by 34 percent by 2020, the House of Commons is now looking to the parliamentary estate and considering installing solar panels on the face of Big Ben in London. Parliamentary passholders were submitting ideas for reducing carbon emissions and boosting energy efficiency on the estate, when the solar idea was suggested.

Renewable energy helps Scotland become one of the world's wealthiest nations
March 11, 2014 03:32 PM - ClickGreen Staff, ClickGreen

Scotland’s control over a quarter of Europe’s offshore wind and marine energy has helped it become one of the world’s wealthiest nations, according to new analysis released today. The new figures from the Scottish Government show that Scotland with its broad base of economic strengths would be ranked as the 14th wealthiest nation per head within the OECD, the grouping of the world’s richest countries.

Many small glaciers make up the whole in Greenland
March 11, 2014 09:59 AM - George Hale, NASA

Research using NASA data is giving new insight into one of the processes causing Greenland's ice sheet to lose mass. A team of scientists used satellite observations and ice thickness measurements gathered by NASA's Operation IceBridge to calculate the rate at which ice flows through Greenland's glaciers into the ocean. The findings of this research give a clearer picture of how glacier flow affects the Greenland Ice Sheet and shows that this dynamic process is dominated by a small number of glaciers.

COLLEGIATE CORNER: Trash talk: Ocean Dumping
March 10, 2014 11:01 AM - McKaylee Reavis, Class of 2015, Wakefield High School, Arlington, VA

Remember the excitement that filled your body when your parents told you the family was going to go to the beach? Remember the excitement slowly leaving your body when you witnessed the trash that covered the beach for miles? Ocean dumping has become a major problem for marine life and the people who enjoy its many benefits. Many marine animals have suffered from the trash in the water and people have suffered from the sight of trash filling the ocean and cluttering the beaches ruining their supposed beautiful day. Industries, cities, and militaries have been dumping their waste into the ocean for years now. One solution to prevent this problem is to impose stricter restrictions on ocean dumping that range from pedestrian waste to toxic nuclear hazard.
