“The potential role of anthropogenic carbon dioxide emissions from coal fired power plants and other industrial plants in global climate change is driving studies of sedimentary basins in Arizona for their carbon sequestration potential.” Quote from the Arizona Geological Survey Repository.
“The heat from warm river waters draining into the Arctic Ocean is contributing to the melting of Arctic sea ice each summer. [...] NASA used satellite data to measure the surface temperature of the waters discharging from a Canadian river into the icy Beaufort Sea during the summer of 2012. They observed a sudden influx of warm river waters into the sea that rapidly warmed the surface layers of the ocean, enhancing the melting of sea ice.”
A post on the Nature News Blog reports that by 2030 the Norther Sea Route through the Arctic Ocean above Eurasia is expected to be navigable for nine weeks per year. The Northwest Passage through the Canadian Arctic Archipelago is expected to be navigable for five weeks per year.
A review of more than 200 earlier studies confirms that U.S. emissions of methane are considerably higher than official estimates. Leaks from the nation’s natural gas system are an important part of the problem.
A Nature article reports how some researchers believe that climate change can be mitigated by crushing olivine-rich rocks and exposing them to weathering – to take advantage of olivine’s ability to sequester carbon.
“Los Angeles, a metropolis perched on the edge of a coast, can expect to experience sea level rise of as much as two feet due by 2050 due to climate change, according to current projections.” Quoted from the USC press release.
“Although few people live in the Western tropical Pacific Ocean region, the remote waters there affect billions of people by shaping climate and air chemistry worldwide.
Next week, scientists will head to the region to better understand its influence on the atmosphere–including how that influence may change in coming decades if storms over the Pacific become more powerful with rising global temperatures.” Quoted from the NSF press release.
“Researchers have discovered a new aquifer in the Greenland Ice Sheet that holds liquid water all year long in the otherwise perpetually frozen winter landscape. [...] The reservoir is known as a “perennial firn aquifer” because water persists within the firn – layers of snow and ice that don’t melt for at least one season.” Quoted from The University of Utah press release.
Messages in a bottle are usually found at beaches, however, one was recently found in a rock cairn on Ward Hunt Island, the closest land point in Canada to the North Pole. The message was dated 1959 and asked the finder to help document evidence of climate change.
“The United States is losing wetlands in coastal watersheds at a significant rate, according to a new report released today by the U.S. Fish and Wildlife Service and the National Oceanic and Atmospheric Administration. [...] It concludes that more than 80,000 acres of coastal wetlands are being lost on average each year, up from 60,000 acres lost per year during the previous study.” Quoted from the U.S. Fish and Wildlife Service press release.
“Communities and coastal habitats in the southern Chesapeake Bay region face increased flooding because, as seawater levels are rising in the bay, the land surface is also sinking. A USGS report concludes that intensive groundwater withdrawals are a major cause of the sinking land, or ‘land subsidence’, that contributes to flooding risks in the region.” Quoted from the USGS press release.
“Human activities, a changing climate and natural disasters are rapidly altering the face of our planet. Now, with NASA’s Images of Change iPad application, users can get an interactive before-and-after view of these changes.” Quoted from the NASA press release.
“The U.S. Geological Survey recently completed an evaluation of the technically accessible storage resource for carbon dioxide for 36 sedimentary basins in the onshore areas and State waters of the United States.” Quoted from the USGS press release.
Christina Figueres, Executive Director of the UN Framework Convention on Climate Change, said… “It is abundantly clear that further capital expenditures on coal can only go ahead if they are compatible with the 2 degree Celsius limit.” Quoted from the United Nations News Center.
“The ravages of deforestation, wildfires, windstorms and insects on global forests during this century are revealed in unprecedented detail in a new study based on data from the NASA-U.S. Geological Survey Landsat 7 satellite.” Quoted from the NASA press release.
“Rising global temperatures and changing human actions will significantly affect the behavior and distribution of mercury worldwide, according to a recent article by the U.S. Geological Survey and Harvard University.” Quoted from the USGS press release.
A number of coal-fired power plants are experimenting with adding wood to their fuel stream. It is viewed by some as a way to boost the use of renewable fuels, improve emissions and lower the carbon footprint of the coal plants. The problem: The supply of wood is not reliable!
We have posted views of Earth from NASA’s Suomi satellite that show night illumination and natural gas flaring for oil industry sites in the Bakken Formation, Eagle Ford Shale, Alaska North Slope, United States Gulf, Mexican Gulf, Venezuela Orinoco Field, Brazil offshore basins, North Sea, North Africa onshore, west Africa offshore, and Persian Gulf.
“Models used by the IPCC estimate global temperature and precipitation patterns will change throughout the 21st century given current rising greenhouse gas levels. This video depicts a scenario in which carbon dioxide concentrations reach 670 parts per million by 2100, up from around 400 ppm today.” Quoted from the NASA video release.
“The continued accumulation of sand within the iconic ring-shaped reefs inside Maldivian atolls could provide a foundation for future island development new research suggests. Islands like the Maldives are considered likely to be the first to feel the effects of climate change induced sea level rise, with future island growth essential to counter the threat of rising sea levels.” Quoted from the press release by the University of Exeter.
Four coal-fired power plants in Beijing will be replaced with natural gas units by the end of 2014. The $7.8 billion project will cut 10,000 tons of sulfur dioxide emissions. At the present time, natural gas has a much higher price in China than it does in the United States.
“United Nations officials called for a global response to combat climate change, following new findings by a scientific panel stating it is “extremely likely” that humans have been the dominant cause of unprecedented global warming since 1950.” Quoted from the United Nations press release.
“As public-health officials continue to fight malaria in sub-Saharan Africa, researchers are trying to predict how climate change will impact the disease, which infected an estimated 219 million people in 2010 and is the fifth leading cause of death worldwide among children under age 5.” Quoted from the MIT press release.
