Global Climate Change


Arctic Climate More Vulnerable Than Previously Thought

First analyses of the longest sediment core ever collected on land in the Arctic, published this week in Science, provide dramatic, "astonishing" documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million years.

Top Predators Key to Extinctions as Planet Warms

Global warming may cause more extinctions than predicted if scientists fail to account for interactions among species in their models, Yale and UConn researchers argue in Science.

Melting Sea Ice Threatens Emperor Penguins

If global temperatures continue to rise, the Emperor penguins in Terre Adélie, in East Antarctica, may eventually disappear, according to a new study by led by researchers from the Woods Hole Oceanographic Institution (WHOI).

Hot Weather for Southern New England Means Poor Air Quality

Unhealthy air quality is predicted for the southern portions of Connecticut and Rhode Island, and the south coast of Massachusetts, including Cape Cod and the Islands, on Wednesday due to ground-level ozone.

Expansion of Forests in the European Arctic Could Result in the Release of Carbon Dioxide

Carbon stored in Arctic tundra could be released into the atmosphere by new trees growing in the warmer region, exacerbating climate change, scientists have revealed.

May 2012 Global Temperatures Second Warmest On Record

The globally-averaged temperature for May 2012 marked the second warmest May since record keeping began in 1880.

As World Warms, Conservation Evolves

Climate and Conservation offers a glimpse of climate change beyond images of melting Arctic ice—illustrating that landscapes and seascapes in places like the coastal Caribbean, mountainous eastern Australia, and the Brazilian Amazon are all susceptible to climate related impacts.

Ancient Warming Greened Antarctica, Study Finds

A new university-led study with NASA participation finds ancient Antarctica was much warmer and wetter than previously suspected.



Global Climate Change: Underestimated Impact of Sea Level Rise on Habitat Loss?

The hidden impact of sea-level rise: current projections may be underestimating the consequences of global climate change on habitat loss.

Big Uncertainties in the Global Water Budget

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.

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.

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.

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).
