Philippines may lose 167,000 hectares to global warming
More than 167,000 hectares of coastland — about 0.6% of the country's total area — are projected to go underwater in the Philippines, especially in low-lying island communities, according to research by the University of the Philippines.Low-lying countries with an abundance of coastlines are at significant risk from rising sea levels resulting from global warming.…

Some Ice Sheets in Greenland slowing their movement
In the face of decades of increasing temperatures and surface melting, the movement of the southwest portion of the Greenland Ice Sheet that terminates on land has been slowing down, according to a new study being published by the journal Nature on Oct. 29.Researchers derived their results by tracking ice sheet movement through Landsat satellite images taken…

California's Isla Rasa being abandoned by seabirds
Isla Rasa, in the Gulf of California, is renowned for its massive aggregations of nesting seabirds. Over 95 percent of the world populations of Elegant Terns and Heerman's Gulls concentrate unfailingly every year on this tiny island to nest. Ever since the phenomenon was described by L. W. Walker in 1953 the island has been…

Action to limit CO2 emissions IS needed now!
Carbon dioxide emissions continue to track the high end of emission scenarios, eroding the chances to keep global warming below 2°C, and placing increased pressure on world leaders ahead of the United Nations Climate Summit on the 23rd September. Global carbon dioxide emissions from fossil fuel combustion and cement production grew 2.3 per cent to…

How plants respond to climate change
Swiss plants, butterflies and birds have moved 8 to 42 meters uphill between 2003 and 2010, as scientists from the University of Basel write in the online journal PLoS One. Climate warming is changing the distribution of plants and animals worldwide. Recently it was shown that in the past two decades, European bird and butterfly…

A challenge in assessing the impacts of climate change on the oceans
Assessing the effect of climate change on upwelling ecosystems is essential to be able to predict the future of marine resources. The zones concerned by this upwelling of cold deep water, which is very rich in nutrients, provide up to 20 % of global production of fish. Since the 1990s, the theory adopted by the…

Wheat production would be reduced by rising temperatures
Any producer will tell you, growing a healthy, high-yielding wheat crop takes skill and hard work. Quality drought-tolerant varieties that are resistant to pests and disease are important. And cooperation from Mother Nature in terms of temperature and precipitation doesn’t hurt, either. To quantify the impact of genetic improvement in wheat, disease and climate change…

Sea Levels dropped in 2010 -2011, why?
In 2011, scientists at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., and the University of Colorado at Boulder reported that between early 2010 and summer 2011, global sea level fell sharply, by about a quarter of an inch, or half a centimeter. Using data from the NASA/German Aerospace Center’s Gravity Recovery and Climate Experiment (GRACE)…

Global Warming Down Under
Green spaces, trees and bodies of water are must-have design features for future development in Sydney’s suburbs after researchers found that by 2050 global warming combined with Sydney’s urban heat island effect could increase temperatures by up to 3.7°C. The researchers from the ARC Centre of Excellence for Climate System Science found new urban developments,…

Which emits more CO2, corn fields or home lawns?
More carbon dioxide is released from residential lawns than corn fields according to a new study. And much of the difference can likely be attributed to soil temperature. The data, from researchers at Elizabethtown College, suggest that urban heat islands may be working at smaller scales than previously thought. These findings provide a better understanding…
