A new university-led study with NASA participation finds ancient Antarctica was much warmer and wetter than previously suspected.
The hidden impact of sea-level rise: current projections may be underestimating the consequences of global climate change on habitat loss.
A study in the Journal of Hydrometeorology now outlines significant differences of global models and measurement data sets. As the network of measurement stations worldwide is shrinking dramatically, uncertainties are increased.
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.
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.
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.
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.
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.
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.
The dramatic meltoff of Arctic sea ice due to climate change is hitting closer to home than millions of Americans might think.
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.
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).
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.
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.
On Friday, PBS NewsHour reporter Hari Sreenivasan will report on how rising sea levels in coastal Louisiana are threatening Native Americans' tribal lands.
Paving a highway across South America is providing lessons on the impact of road construction elsewhere.
Far more wild plant species may be responding to global warming than previous large-scale estimates have suggested.
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.
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.
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.
