Mountains warming faster than expected
April 24, 2015 03:28 PM - Janet Lathrop, UMassAmherst

High elevation environments around the world may be warming much faster than previously thought, according to members of an international research team including Raymond Bradley, director of the Climate System Research Center at the University of Massachusetts Amherst. They call for more aggressive monitoring of temperature changes in mountain regions and more attention to the potential consequences of warming.

What's worse for polar bears- Global Warming or Pollution?
April 24, 2015 02:44 PM - Tim Radford, The Ecologist

As if melting ice in Polar bears' Arctic habitat was not enough, Norwegian scientists have found that organic pollutants such as pesticide residues are disrupting their thyroid and endocrine systems, adding a further threat to the species' survival.

Microbes have major effect on climate change

Carbon, held in frozen permafrost soils for tens of thousands of years, is being released as Arctic regions of the Earth warm and is further fueling global climate change, according to a Florida State University researcher.

Putting a value on our Oceans
April 23, 2015 06:56 AM - World Wildlife Fund, Justmeans

The ocean’s wealth rivals those of the world’s leading economies, but its resources are rapidly eroding, according to a new World Wildlife Fund (WWF) report. The analysis, Reviving the Ocean Economy: The Case for Action, conservatively estimates the value of key ocean assets to be at least $24 trillion. If compared to the world’s top 10 economies, the ocean would rank as the seventh largest, with an annual value of goods and services of $2.5 trillion.

The report, produced in association with The Global Change Institute at the University of Queensland and The Boston Consulting Group (BCG), combines scientific evidence of environmental degradation with an economic case for urgent conservation action. Using an innovative economic analysis, the ocean’s value is quantified based on assessments of goods and services ranging from fisheries to coastal storm protection, resulting in an overall asset value and an annual dividend output (comparable to a GDP).

A brief history of Earth Day
April 22, 2015 09:59 PM - Earth Day Network

Each year, Earth Day -- April 22 -- marks the anniversary of what many consider the birth of the modern environmental movement in 1970.

The height of hippie and flower-child culture in the United States, 1970 brought the death of Jimi Hendrix, the last Beatles album, and Simon & Garfunkel’s “Bridge Over Troubled Water”. Protest was the order of the day, but saving the planet was not the cause. War raged in Vietnam, and students nationwide increasingly opposed it.

 

US leads the world in EV adoption
April 21, 2015 03:38 PM - ClickGreen Staff, ClickGreen

The United States currently leads the world in the number of plug-in electric vehicles on the road, capturing 41% of the global market. Though the market can be traced back to the early-to-mid 1990s with the release of the Chrysler TEVan and the General Motors EV1, it wasn’t until the second wave of vehicles such as the Nissan Leaf and the Chevrolet Volt, both introduced in 2010, that plug-in electric cars started to become a success in the US.

It was Tesla Motors with its Roadster series which first entered production in 2008 that reignited this interest in the market though. The small company was founded by Martin Eberhard and Marc Tarpenning in 2003 before current CEO Elon Musk joined the company the following year and led the business to new heights with links to new battery technologies that made plug-in electrical vehicles a more viable option for everyday journeys.

Limited nutrients may keep plants from growing as fast as scientists thought
April 21, 2015 09:00 AM - Tim Wogan, Science/AAAS

Plants are one of the last bulwarks against climate change. They feed on carbon dioxide, growing faster and absorbing more of the greenhouse gas as humans produce it. But a new study finds that limited nutrients may keep plants from growing as fast as scientists thought, leading to more global warming than some climate models had predicted by 2100.

US energy-related CO2 emissions increase for second year in a row

For the second year in a row, energy-related carbon dioxide (CO2) emissions in the United States have increased, according to the latest official figures. However, unlike 2013, when emissions and gross domestic product (GDP) grew at similar rates (2.5% and 2.2%, respectively), 2014's CO2 emissions growth rate of 0.7% was much smaller than the 2014 GDP growth rate of 2.4%.

Electric vehicle sales booming in France, Germany, UK

France is leading Europe’s electric vehicle revolution with the nation now accounting for more than a quarter of EV sales across the EU, new figures reveal.

Data released by the European Environment Agency shows around 38 000 electric vehicles were registered in 2014, up by 57 % compared to 2013. 

Lake Mead water levels continuing to drop
April 19, 2015 07:45 AM - Kirk Siegler/NPR

The historic four-year drought in California has been grabbing the headlines lately, but there's a much bigger problem facing the West: the now 14-year drought gripping the Colorado River basin.

One of the most stunning places to see its impact is at the nation's largest reservoir, Lake Mead, near Las Vegas. At about 40 percent of capacity, it's the lowest it's been since it was built in the 1930s.
