When the Last Cooling Trend Ended|
April 24, 2013 | National Science Foundation
“The most comprehensive evaluation of temperature change on Earth’s continents over the past 1,000 to 2,000 years indicates that a long-term cooling trend–caused by factors including fluctuations in the amount and distribution of heat from the sun, and increases in volcanic activity–ended late in the 19th century.” Quoted from the National Science Foundation press release.
Fast Cycling Pollutants and Sea Level Rise|
April 17, 2013 | National Science Foundation
“Scientists found that reductions in four pollutants that cycle comparatively quickly through the atmosphere could temporarily forestall the rate of sea level rise by roughly 25 to 50 percent: [...] methane, tropospheric ozone, hydrofluorocarbons and black carbon.” Quoted from the National Science Foundation press release.
Ecosystems of Africa Map|

Global Land Warming Confirmed|
April 9, 2013 | Cooperative Institute for Research in Environmental Sciences
“A new observational study that did not use temperature recordings from land stations has confirmed global land warming, according to a scientist at NOAA’s Cooperative Institute for Research in Environmental Sciences. The finding refutes concerns that artifacts in land-based observing systems have led to an artificial global land warming trend.” Quoted from the CIRES press release.
The Last Hot Spell|
April 7, 2013 | National Science Foundation
“Temperature patterns during Earth’s last prolonged global “hot spell”–the Pliocene, some 5.3 to 2.6 million years ago–differed dramatically from those of modern times.” Quoted from the NSF press release.
Extreme Algal Blooms|
April 5, 2013 | National Science Foundation
“A 2011 record-breaking algae bloom in Lake Erie was triggered by long-term agricultural practices coupled with extreme precipitation, followed by weak lake circulation and warm temperatures, scientists have discovered.” Quoted from the National Science Foundation press release.

NORM from the Marcellus Shale|
March 12, 2013 | Pennsylvania Department of Environmental Protection
“Drill cuttings and other materials associated with oil and gas have occasionally triggered radiation monitors at landfills. DEP’s data indicates that less than half a percent of all drill cuttings produced by the Marcellus Shale industry in 2012 that were disposed of in landfills triggered radiation monitors. The cuttings did not contain levels of radioactivity that would be harmful to the public, and they were safely disposed of in the landfills.” Quoted from the DEP announcement.
