Study Suggests Drastic Changes Needed to Curb Most Potent Greenhouse Gas

Meat consumption in the developed world needs to be cut by 50 percent per person by 2050 if we are to meet the most aggressive strategy, set out by the Intergovernmental Panel on Climate Change (IPCC), to reduce one of the most important greenhouse gases, nitrous oxide (N2O).

Rapid Climate Change Threatens Asia's Rice Bowl

As Asia's monsoon season begins, leading climate specialists and agricultural scientists warned today that rapid climate change and its potential to intensify droughts and floods could threaten Asia's rice production and pose a significant threat to millions of people across the region.

New Forage Plant Prepares Farmers for Climate Changes

Researchers, including plant researchers from the University of Copenhagen, have developed a new type of the corn-like crop sorghum, which may become very significant for food supplies in drought-prone areas.

Ecologist Simulates Climate Change with Infrared Heaters

Climate change is leading to higher temperatures around the world, forcing plants, trees and animals to adapt to new conditions or relocate, often to higher elevations. But the process is gradual, and the effects of climate warming can usually only be observed over the course of years and decades.

Many Forests Feeling the Heat from Climate Change

Greenhouse Gas Can Find a Home Underground

A new study by researchers at MIT shows that there is enough capacity in deep saline aquifers in the United States to store at least a century's worth of carbon dioxide emissions from the nation's coal-fired powerplants. Though questions remain about the economics of systems to capture and store such gases, this study addresses a major issue that has overshadowed such proposals.

Lung Doctors Expect Respiratory Diseases will Worsen with Global Climate Change

Worldwide increases in the incidences of asthma, allergies, infectious and cardiovascular diseases will result from a variety of impacts of global climate change, including rising temperatures, worsening ozone levels in urban areas, the spread of desertification, and expansions of the ranges of communicable diseases as the planet heats up, the professional organization representing respiratory and airway physicians stated in a new position paper.

With Climate Change U.S. Could Face Risk From Chagas Disease

Chagas disease, a parasite-borne illness carried by kissing bugs afflicts millions of people in Central and South America today.



Study Suggests Asian Emissions Contribute to Air Pollution in Western United States

As Asian countries develop, they are emitting more ozone precursors that pollute surface level air. Many studies have documented this pollution being carried by air currents to the western United States.

EPA Proposes to Keep Greenhouse Gas Permitting Requirements Focused on Largest Emitters

The U.S. Environmental Protection Agency (EPA) is proposing not to change the greenhouse gas (GHG) permitting thresholds for the Prevention of Significant Deterioration (PSD) and Title V Operating Permit programs.

Reduction in U.S. Carbon Emissions Attributed to Cheaper Natural Gas

In 2009, when the United States fell into economic recession, greenhouse gas emissions also fell, by 6.59 percent relative to 2008.

Arctic Sea Ice Decline May Be Driving Snowy Winters Seen in Recent Years

A new study led by the Georgia Institute of Technology provides further evidence of a relationship between melting ice in the Arctic regions and widespread cold outbreaks in the Northern Hemisphere. The study’s findings could be used to improve seasonal forecasting of snow and temperature anomalies across northern continents.

Study Suggests Nation's Urban Forests Losing Ground

National results indicate that tree cover in urban areas of the United States is declining at a rate of about four million trees per year, according to a U.S. Forest Service study published recently in Urban Forestry & Urban Greening.

Human Evolution Linked to Climate Change?

It’s not a take on climate change we often hear about. However, one man believes the two are connected.

Indigenous People's Water Supply Polluted by Climate Change Effects

Indigenous people around the world are among the most vulnerable to climate change and are increasingly susceptible to the pathogen loads found in potable water after heavy rainfall or rapid snow melt.

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.
