New data released by the Northeast Regional Climate Center at Cornell University shows the Northeast’s seven-month average (January through July) of 49.9 degrees was the warmest such period since 1895, the year such record keeping began.
The simple model of how plants handle climate change doesn't always explain what's going on.
When it comes to gnarly weather, tornadoes, blizzards and hurricanes seem to get most of our attention, perhaps because their destructive power makes for imagery the media can't ignore. But for sheer killing power, heat waves do in far more people than even the most devastating hurricane. Ask medical historian Richard Keller.
A University of Washington researcher and colleagues discovered the critically endangered bowhead whales singing like birds in the Fram Strait, indicating that the whales might be more populous than previously thought or that they sing a wide repertoire of songs, unlike other whales.
After Columbus’ voyage, burning of New World forests and fields diminished significantly – a phenomenon some have attributed to decimation of native populations. But a University of Utah-led study suggests global cooling resulted in fewer fires because both preceded Columbus in many regions worldwide.
The chronic drought that hit western North America from 2000 to 2004 left dying forests and depleted river basins in its wake and was the strongest in 800 years, but those conditions will become the “new normal” for most of the coming century. Such climatic extremes have increased as a result of global warming.
The volume of "green" advertising rises and falls in conjunction with key indicators of economic growth. That's the finding from a study of 30 years of environmental ads in National Geographic Magazine.

Jessica Rennells, a climatologist with the Northeast Regional Climate Center at Cornell University, comments on data released today confirming that the first six months of 2012 are drier than normal – and that those conditions are expected to persist in a band stretching from Lake Erie to Albany as well as western Pennsylvania. NOTE: An online drought monitor and seasonal drought outlooks are available at: www.droughtmonitor.unl.edu/forecast.html
Data released this week paints a grim picture for farmers throughout the United States. Almost everywhere, fruit, crop, livestock and dairy farmers are being choked by the driest growing season since 1956. Researchers in the College of Agriculture and Life Sciences at Cornell University are available to talk with the media about the impacts of the Drought of 2012.
An ice island twice the size of Manhattan has broken off from Greenland’s Petermann Glacier, according to researchers at the University of Delaware and the Canadian Ice Service. This marks the second massive break in two years.
A new study released by the Wildlife Conservation Society and partners says that the distribution of wolverines in the wild relates to the species’ ability to store and “refrigerate” their food supply through tough times. The cold caches play a particularly important role in wolverine reproductive success, as they provide a source of nutrition for lactating females while they are nursing young.
University of Washington researchers found that the decline in milk production due to climate change will vary across the U.S., since there are significant differences in humidity and how much the temperature swings between night and day across the country.
Jessica Rennells, a climatologist and extension support specialist at the Northeast Regional Climate Center at Cornell University, comments on data released today by the center that shows the region’s July heat wave broke records for longevity, and came close to all-time temperature records.
No matter how you drill it, using natural gas as an energy source is a smart move in the battle against global climate change and a good transition step on the road toward low-carbon energy, according to a new study by Cornell Professor Lawrence M. Cathles published in the most recent edition of the peer-reviewed journal Geochemistry, Geophysics and Geosystems.
Elevated levels of atmospheric carbon dioxide accelerate carbon cycling and soil carbon loss in forests, new research led by an Indiana University biologist has found. The new evidence supports an emerging view that although forests remove a substantial amount of carbon dioxide from the atmosphere, much of the carbon is being stored in living woody biomass rather than as dead organic matter in soils.
Kansas geologists are doing a comprehensive statewide study on using rocks for long-term storage of carbon dioxide.
A University of Saskchewan-led international research team has discovered that aerosols from relatively small volcanic eruptions can be boosted into the high atmosphere by weather systems such as monsoons, where they can affect global temperatures.
The recent heat wave baking much of the country has prompted many people to ask: Is this due to climate change?
Researchers have long believed that the longer days and calmer seas of spring set off an annual bloom of plants in the North Atlantic, but University of Washington scientists and collaborators discovered that warm eddies fuel the growth three weeks before the sun does.
Northern states could face longer outbreak seasons than the Southern region.
University of Adelaide researchers have discovered that recent climate change is causing leaves of some Australian plants to narrow in size.
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.
Climate change could exacerbate existing threats to critically endangered leatherback sea turtles and nearly wipe out the population in the eastern Pacific. Deaths of turtle eggs and hatchlings in nests buried at hotter, drier beaches are the leading projected cause of the potential climate-related decline, according to a new study in the journal Nature Climate Change by a research team from Drexel University, Princeton University, other institutions and government agencies.
American Society of Agronomy Provides Panel of Experts to Answer Questions Related to Heat and Dry Conditions
New research concludes that a one-two punch of drought and mountain pine beetle attacks are the primary forces that have killed more than 2.5 million acres of pinyon pine and juniper trees in the American Southwest during the past 15 years, setting the stage for more ecological disruption - including major soil erosion and further loss of water in the Colorado River basin.
Ice samples pulled from nearly a mile below the surface of Greenland glaciers have long served as a historical thermometer, adding temperature data to studies of the local conditions up to the Northern Hemisphere’s climate. But the method — comparing the ratio of oxygen isotopes buried as snow fell over millennia — may not be such a straightforward indicator of air temperature.
A decline in the population of emperor penguins appears likely this century as climate change reduces Antarctic sea ice, according to a detailed projection published this week. The study concludes that the number of breeding pairs in a much-observed penguin colony may drop by about 80 percent by 2100.
New research shows that substantial vegetation – including stunted trees – sprouted on the frozen continent 15 million years ago.
All of the methane escaping into the atmosphere causes more melting ice, oceanographer Jeff Chanton says, which causes sea levels to rise and could affect coastal real estate values — sooner rather than later.
A landmark book released by the Wildlife Conservation Society through Island Press shows that people in diverse environments around the world are moving from climate science to conservation action to ensure their natural systems, wildlife and livelihoods can withstand the pressures of global warming.
Some regions expected to have more wildfires while others will have fewer.
Jessica Rennells, a climatologist at the Northeast Regional Climate Center at Cornell University, comments on data released this week by the center that shows this spring ranks among the hottest on record throughout the region.
Compared to global seasonal norms, May 2012 was the fourth warmest in the 34-year satellite record, according to Dr. John Christy, a professor of atmospheric science and director of the Earth System Science Center at The University of Alabama in Huntsville.
Two analyses highlight the growing polarization of public attitudes toward climate change, as well as the role “psychological distance” plays in levels of concern.
A chance discovery of 80-year-old photo plates in a Danish basement is providing new insight into how Greenland glaciers are melting today.
When leatherback turtle hatchlings dig out of their nests buried in the sandy Playa Grande beach in northwest Costa Rica, they enter a world filled with dangers. This critically endangered species faces threats that include egg poaching and human fishing practices. Now, Drexel University researchers have found that the climate conditions at the nesting beach affect the early survival of turtle eggs and hatchlings. They predict, based on projections from multiple models, that egg and hatchling survival will drop by half in the next 100 years as a result of global climate change.
