Though worries about “nuclear winter” have faded since the end of the Cold War, existing stockpiles of nuclear weapons still hold the potential for devastating global impacts.
Cyanobacterial populations have increased in recent decades and scientists suspect that global warming may be behind the phenomenon.
University of Adelaide researchers have discovered that recent climate change is causing leaves of some Australian plants to narrow in size.
For eastern Pacific populations of leatherback turtles, the 21st century could be the last. New research suggests that climate change could exacerbate existing threats and nearly wipe out the population.
The vagaries of South Asian summer monsoon rainfall impact the lives of more than one billion people.
The study is the first to give a comprehensive projection for this long perspective, based on observed sea-level rise over the past millennium, as well as on scenarios for future greenhouse-gas emissions.
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.
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.
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).
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.
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.
The globally-averaged temperature for May 2012 marked the second warmest May since record keeping began in 1880.
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.
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.
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.
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.
