Current Rates of Ocean Acidification are Unparalleled in Earth's History
Mar 02, 2012 07:37 AM E
The study, based on an expert workshop led by Columbia University's Lamont-Doherty Earth Observatory and the University of Bristol, assessed in detail a number of climate change events in the planet's history, including the asteroid impact that made the dinosaurs go extinct and the Permian mass-extinction which wiped out around 95 per cent of all life on Earth.
Icelandic Dust
New Study links Dust to Increased Glacier Melting, Ocean Productivity
Mar 02, 2012 07:30 AM E
A University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study shows a link between large dust storms on Iceland and glacial melting. The dust is both accelerating glacial melting and contributing important nutrients to the surrounding North Atlantic Ocean. The results provide new insights on the role of dust in climate change and high-latitude ocean ecosystems.

Call for Tough New Targets on European Union Energy Reduction
Feb 27, 2012 08:28 AM E
Energy efficiency experts at the University of East Anglia (UEA) are calling for ambitious new targets to reduce energy demand across the European Union. In a report published today by the Build with CaRe consortium, the researchers propose a new EU target of a 40 per cent reduction in primary energy demand by 2050.
Sifrhippus Compared with a Modern Horse
Evolution of Earliest Horses Driven by Climate Change
Feb 24, 2012 11:08 AM E
When Sifrhippus sandae, the earliest known horse, first appeared in the forests of North America more than 50 million years ago, it would not have been mistaken for a Clydesdale. It weighed in at around 12 pounds--and it was destined to get much smaller over the ensuing millennia.

Protecting the Climate by Reducing Fluorinated Greenhouse Gas Emissions
Feb 24, 2012 10:29 AM E
Hydrofluorocarbons (HFCs), which have been used in recent years in increasing quantities as substitutes for CFCs, are also climatically very active and many are also extremely long-lived. In the renowned journal Science an international team of researchers recommends that the most potent of these gases also be regulated.

World Nourishment at Risk of Being Diminished: Wild Cereals Threatened by Global Warming
Feb 23, 2012 11:08 AM E
A 28-year comparative study of wild emmer wheat and wild barley populations has revealed that these progenitors of cultivated wheat and barley, which are the best hope for crop improvement, have undergone changes over this period of global warming. The changes present a real concern for their being a continued source of crop improvement.

Yosemite's Alpine Chipmunks Take Genetic Hit from Climate Change
Feb 20, 2012 11:53 AM E
Global warming has forced alpine chipmunks in Yosemite to higher ground, prompting a startling decline in the species' genetic diversity, according to a new study by researchers at the University of California, Berkeley.

Hidden in Plain Sight, Concrete Holds a Strange History
Feb 18, 2012 06:49 AM E
Concrete: We use it for our buildings, bridges, dams, and roads. We walk on it, drive on it, and many of us work within its walls. Yet very few of us know what it is. We take the substance that is the basis of this familiar landscape for granted; yet the story of its creation and development features a cast of fascinating characters and remarkable historical episodes.

Climate Change Threatens Tropical Birds
Feb 16, 2012 09:18 AM E
Climate change spells trouble for many tropical birds – especially those living in mountains, coastal forests and relatively small areas – and the damage will be compounded by other threats like habitat loss, disease and competition among species.

Quantifying Climate Impacts: New Comprehensive Model Comparison Launched
Feb 07, 2012 09:50 AM E
Climate change has impacts on forests, fields, rivers - and thereby on humans that breathe, eat and drink. To assess these impacts more accurately, a comprehensive comparison of computer-based simulations from all over the world will start this week. For the first time, sectors ranging from ecosystems to agriculture to water supplies and health will be scrutinized in a common framework.

Warming in the Tasman Sea a Global Warming Hot Spot
Jan 31, 2012 23:33 PM E
Oceanographers have identified a series of ocean hotspots around the world generated by strengthening wind systems that have driven oceanic currents, including the East Australian Current, polewards beyond their known boundaries.
