Greenhouse Gases Causing More Frequent Extreme Summer Temps

Extreme summer temperatures are already occurring more frequently in the United States, and will become normal by mid-century if the world continues on a business as usual schedule of emitting greenhouse gases.

Time of Year Significant in Projections of Climate Change Effects

Does it matter whether long periods of hot weather happen in June or July, August or September? Scientists studying the subtle effects of heat waves and droughts say that when such events happen makes a big difference.

Effects of Sea Spray Geoengineering on Global Climate

Anthropogenic climate warming is leading to consideration of options for geoengineering to offset rising carbon dioxide levels. One potential technique involves injecting artificial sea spray into the atmosphere. The sea salt particles would affect Earth's radiation budget directly, by scattering incoming solar radiation, and indirectly, by acting as cloud condensation nuclei, which could lead to whiter clouds that reflect more radiation.

Biosphere Study at the University of Arizona

Scientists are preparing to launch a 10-year project to study water resources, gas exchange and carbon cycling in three man-made landscapes built in a half-acre laboratory at the University of Arizona’s Biosphere 2.

New Model Quantifies Climate Change

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.

New Research Reveals Plants Caused Ice Ages

New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages. Led by the Universities of Exeter and Oxford, the study is published in Nature Geoscience.

Climate Risk of Toxic Shock

The effects of climate change could expose Australians to greater risks from toxic contamination, a leading scientist has warned.

Ancient DNA Holds Clues to Climate Change Adaptation

Thirty-thousand-year-old bison bones discovered in permafrost at a Canadian goldmine are helping scientists unravel the mystery about how animals adapt to rapid environmental change.



Broadcast Study of Ocean Acidification to Date Helps Scientists Evaluate Effects on Marine Life

Might a penguin's next meal be affected by the exhaust from your tailpipe? The answer may be yes, when you add your exhaust fumes to the total amount of carbon dioxide lofted into the atmosphere by humans since the industrial revolution. One-third of that carbon dioxide is absorbed by the world's oceans, making them more acidic and affecting marine life.

Diverse Ecosystems are Crucial Climate Change Buffer

Preserving diverse plant life will be crucial to buffer the negative effects of climate change and desertification in in the world's drylands, according to a new landmark study.

One-third of Car Fuel Consumption is Due to Friction Loss

No less than one third of a car's fuel consumption is spent in overcoming friction. This friction loss has a direct impact on both fuel consumption and emissions. However, new technology can reduce friction from 10 to 80 percent in various components of a car, according to a joint study by VTT Technical Research Centre of Finland and Argonne National Laboratory in the United States.

The Case of the Missing Gas Mileage

Automakers have made great strides in fuel efficiency in recent decades — but the mileage numbers of individual vehicles have barely increased. An MIT economist explains the conundrum.

Weather Deserves Medal for Clean Air During 2008 Olympics

New research suggests that China's impressive feat of cutting Beijing's pollution up to 50 percent for the 2008 Summer Olympics had some help from Mother Nature.

California Proposes Rules to Spur Clean Car Growth

California's Air Resources Board (ARB) is proposing new rules to reduce greenhouse gas emissions from vehicles.

Bordo Poniente Landfill Closure Will Reduce Greenhouse Gas Emissions in Mexico City

A project to close one of the world's largest landfills, the 927-acre Bordo Poniente Landfill in Mexico City will stem the city's largest source of greenhouse gas (GHG) emissions, while creating renewable energy and local jobs.

Predicted Rise of Wildfires in Parts of Canada

Large forest regions in Canada are apparently about to experience rapid change. Based on models, scientists can now show that there are threshold values for wildfires just like there are for epidemics. Large areas of Canada are apparently approaching this threshold value and may in future exceed it due to climate change.

New Study Suggests Removing Sulfur from Jet Fuels Cools Climate

A Yale study examining the impact of aviation on climate change found that removing sulfur from jet fuel cools the atmosphere. The study was published in the Geophysical Research Letters.

As Climate Change Sets In, Plants and Bees Keep Pace

No laggards, those bees and plants. As warm temperatures due to climate change encroach winter, bees and plants keep pace.

Ottawa Cannot Legislate Climate Change Policy

Earlier this year the federal government introduced sector-by-sector emissions reduction regulations as its stand on climate change. However, according to Prof. Al Lucas and co-author Jenette Yearsley, the Constitution limits Ottawa's ability to enact climate change legislation limiting greenhouse gas emissions.

New Scientific Review Highlights Biodiversity and Climate Change

A major new scientific review, involving more than 30 scientists from Australia, New Zealand and the Pacific Islands sets out our current knowledge of the impacts of climate change on biodiversity in the latest special edition of the scientific journal Pacific Conservation Biology.
