Carbon Dioxide in U.S. Rivers and Streams
February 10, 2012 | USGS
“Rivers and streams in the United States are releasing substantially more carbon dioxide into the atmosphere than previously thought. These findings could change the way scientists model the movement of carbon between land, water, and the atmosphere.” Quoted from the USGS press release. |

Evaluation of Geologic Carbon Dioxide Storage
February 9, 2012 | USGS
“This methodology is designed to assess the storage resources in mappable subsurface bodies of rock into which CO2 is injected and trapped; in this methodology, these mappable subsurface bodies of rock are referred to as storage assessment units (SAUs). The total volume of pore space within a SAU can be described as the total in-place resource.” Quoted from the USGS report. |

Heat and Cold Damage Coral in Different Ways
February 9, 2012 | UC San Diego
“Around the world coral reefs are facing threats brought by climate change and dramatic shifts in sea temperatures. While warming has been the primary focus for scientists and ocean policy managers, cold can also cause significant damage.” Quoted from the NSF press release. |

Melting Land Ice and Sea Level Rise
February 8, 2012 | NASA
“In the first comprehensive satellite study of its kind, a University of Colorado at Boulder-led team used NASA data to calculate how much Earth’s melting land ice is adding to global sea level rise.” Quoted from the NASA press release. |

Tree Rings for Measuring Climate Response to Volcanic Eruptions
February 8, 2012 | National Science Foundation
“Some climate cooling caused by past volcanic eruptions may not be evident in tree-ring reconstructions of temperature change because large enough temperature drops lead to greatly shortened or even absent growing seasons, according to climate researchers, who compared tree-ring temperature reconstructions with model simulations of past temperature changes.” |

2011: A Year of Climate Extremes
February 2, 2012 | NOAA
“According to NOAA scientists, 2011 was a record-breaking year for climate extremes, as much of the United States faced historic levels of heat, precipitation, flooding and severe weather, while La Niña events at both ends of the year impacted weather patterns at home and around the world.” Quoted from the NOAA press release. |

Fountain Stream and a Retreating Glacier
January 25, 2012 | Ground Truth Trekking
“Fountain Stream is one of the largest rivers draining Malaspina Glacier. The changes in this river over the past 120 years provides an example of how glacial retreat can starve rivers of sediment and lead to erosion downstream, and an example of the complex changes that can result from climate change.” |

Drilling Report from the Iberian Coast
January 24, 2012 | National Science Foundation
“Mediterranean bottom currents and the sediment deposits they leave behind offer new insights into global climate change, the opening and closing of ocean circulation gateways and locations where hydrocarbon deposits may lie buried under the sea.” |

Global Warming and Coastal Erosion – Alaska Case Study
January 23, 2012 | Ground Truth Trekking
” The storm we watched eroded 10 feet of forest floor. Beneath the tree roots, we could see the remains of beaches formed only a few decades ago, when a surplus of sand was still flowing from the glacier.” Quoted from the case study.

ESA: Arctic Fresh Water Dome Could Spill into the Atlantic
January 23, 2012 | European Space Agency
“ESA satellites show that a large dome of fresh water has been building up in the Arctic Ocean over the last 15 years. A change in wind direction could cause the water to spill into the north Atlantic, cooling Europe.” Quote from the ESA website. |

Climate Clues from Glacial Cores
January 11, 2012 | Ohio State University
“Researchers are beginning their analysis of what are probably the first successful ice cores drilled to bedrock from a glacier in the eastern European Alps.” Quoted from the Ohio State University press release. |

Global Risks 2012
January 11, 2012 | World Economic Forum
The World Economic Forum just released their annual report, Global Risks 2012, that describes 50 global risks grouped into economic, environmental, geopolitical, societal and technological categories. Some of these risks are geoscience based and include rising greenhouse gas emissions, volatility in energy prices and more. |

Reaction of Plants to Human-Induced Climate Change
December 19, 2011 | NASA
NASA researchers “investigated how Earth’s plant life is likely to react over the next three centuries as Earth’s climate changes in response to rising levels of human-produced greenhouse gases.” Quote from the NASA press release. |

The Consequences of Permafrost Melting
December 16, 2011 | University of Alaska Fairbanks
“As the Arctic warms, greenhouse gases will be released from thawing permafrost faster and at significantly higher levels than previous estimates. This thawing will release approximately the same amount of carbon as deforestation. However, the effect of thawing permafrost on climate will be 2.5 times greater because emissions include methane.” Quoted from the University of Alaska Fairbanks press release. |

Climate Change Evidence from Dead Sea Evaporites
December 16, 2011 | University of Minnesota
“An international team of scientists drilling deep under the bed of the Dead Sea has found evidence that the sea may have dried up during a past warm period similar to predicted scenarios for climate change in coming decades.” Quoted from the University of Minnesota press release. |

Greenland Lost 430 Gigatons of Ice in 2011
December 12, 2011 | NOAA
“According to the Arctic Report Card, ice mass loss from Greenland in 2011 was about 430 gigatons—enough ice to raise global sea level by just over 1 millimeter.” Quoted from NASA’s Earth Observatory.
* Data for 2011 is available before the end of the calendar year because the melt season is over. |

Greenland’s 2011 Melt Season
December 11, 2011 | NASA Earth Observatory
Depending on the data analysis approach, 2011 was either the third most extensive or the sixth most extensive melting year since satellite records began in 1979.
* Data for 2011 is available before the end of the calendar year because the melt season is over. |

Flood Threat to Bangkok is Rising
November 14, 2011 | Discovery News
The land beneath Bangkok is subsiding, sea level is rising and that means flood risk for the Thai capital is rapidly increasing. An article in Discovery News explores the threat of flooding for the citizens, businesses and government of Thailand. |

Sea Ice Melting and Ocean Circulation
November 7, 2011 | NASA Earth Observatory
Fresh water produced by the melting of sea ice in the Arctic could produce ocean water density imbalances that could alter global ocean circulation. |

A Diversity of Underground Life
October 26, 2011 | National Science Foundation
For surface life, the greatest biodiversity is generally found in the tropics. However, researchers are finding that biodiversity levels of underground life can be very high at almost any latitude.
