Global Climate Change


Climate Change Will Alter Risks of Wildfire Worldwide, Some Shifts Rapid, Extensive

A Texas Tech University climate scientist said climate change is widely expected to disrupt future fire patterns around the world, with some regions, such as the western United States, seeing more frequent fires within the next 30 years.

Article: Population Growth Leads to Environmental Stress

In an article published in the journal Nature Climate Change, researchers take a critical look at the various factors that have long been prime climate-change suspects. One in particular: The role of population growth.

Humans are Primary Cause of Global Ocean Warming Over Past 50 Years, Research Shows

The oceans have warmed in the past 50 years, but not by natural events alone. New research shows that the observed ocean warming over the last 50 years is consistent with climate models only if the models include the impacts of observed increases in greenhouse gas during the 20th century.

Global Warming Threat Seen in Fertile Soil of Northeastern U.S. Forests

Vast stores of carbon in U.S. forest soils could be released by rising global temperatures, according to a study by UC Irvine and other researchers in today's online Proceedings of the National Academy of Sciences in Washington, D.C.

Today's Climate More Sensitive to Carbon Dioxide Than in Past 12 Million Years

In the journal Nature, paleoclimate researchers reveal that about 12-5 million years ago climate was decoupled from atmospheric carbon dioxide concentrations. In the last five million years, changes in ocean circulation allowed Earth's climate to become more closely coupled to changes in carbon dioxide concentrations in the atmosphere.

Consumption Driving Environment Damage: UN

A group of scientists from around the world is warning that population growth, widespread destruction of natural ecosystems, and climate change may be driving Earth toward an irreversible change in the biosphere, a planet-wide tipping point that would have destructive consequences absent adequate preparation and mitigation.

Arctic Ice Melt is Setting Stage for Severe Winters

The dramatic meltoff of Arctic sea ice due to climate change is hitting closer to home than millions of Americans might think.

Divided Public: Climate Survey Shows Skepticism and Alarm Rising Over the Past Decade

Researchers have found that between 2002 and 2010 the images and emotions that the American public associates with global warming shifted significantly. Four consecutive nationwide surveys found both increasing skepticism and growing alarm among respondents.



What is RICE MACT Compliance?

The term RICE MACT refers to the National Emission Standards for Stationary Reciprocating Internal Combustion Engines (RICE), codified at 40 CFR Part 63, Subpart ZZZZ. The RICE MACT rules apply to any piece of equipment driven by a stationary RICE located at a major source or area source of hazardous air pollutants (HAP).

Energy Supplies Vulnerable to Climate Change

Higher water temperatures and reduced river flows in Europe and the United States in recent years have resulted in reduced production, or temporary shutdown, of several thermoelectric power plants, resulting in increased electricity prices and raising concerns about future energy security in a changing climate.

Warming Turns Tundra to Forest

In just a few decades shrubs in the Arctic tundra have turned into trees as a result of the warming Arctic climate, creating patches of forest which, if replicated across the tundra, would significantly accelerate global warming.

PBS NewsHour Reporting Friday on Rising Sea Levels in Coastal Louisiana

On Friday, PBS NewsHour reporter Hari Sreenivasan will report on how rising sea levels in coastal Louisiana are threatening Native Americans' tribal lands.

Highway Through Amazon Worsens Effects of Climate Change

Paving a highway across South America is providing lessons on the impact of road construction elsewhere.

More Plant Species Responding to Global Warming Than Previously Thought

Far more wild plant species may be responding to global warming than previous large-scale estimates have suggested.

Earth's Water Cycle Intensifying With Atmospheric Warming

A clear change in salinity has been detected in the world's oceans, signalling shifts and an acceleration in the global rainfall and evaporation cycle.

Humanmade Pollutants May Be Driving Earth's Tropical Belt Expansion

Black carbon aerosols and tropospheric ozone, both humanmade pollutants emitted predominantly in the Northern Hemisphere's low- to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in that hemisphere, new research by a team of scientists shows.

USGS Details Effects of Climate Change on Water Availability in 14 Local Basins Nationwide

Climate change projections indicate a steady increase in temperature progressing through the 21st century, generally resulting in snowpack reductions, changes to the timing of snowmelt, altered streamflows and reductions in soil moisture, which could affect water management, agriculture, recreation, hazard mitigation and ecosystems across the nation.

Nearly One Tenth of Western Hemisphere Mammals Unlikely to Outrun Climate Change

A safe haven could be out of reach for 9 percent of the Western Hemisphere's mammals, and as much as 40 percent in certain regions, because the animals just won't move swiftly enough to outpace climate change.

New Research Brings Satellite Measurements and Global Climate Models Closer

One popular climate record that shows a slower atmospheric warming trend than other studies contains a data calibration problem, and when the problem is corrected the results fall in line with other records and climate models, according to a new University of Washington study.

Warming Affects Ecosystems Not Just Biodiversity

Ecosystems perform important tasks – like nutrient cycling, breakdown of waste and carbon storage – on which humans depend, so it's important we understand how climate change might affect them.
