Brown reported from Billings, Mont.Friday, June 18, 2010, 7:12 AM NEW ORLEANS — It is an overlooked danger in oil spill crisis: The crude gushing from the well contains vast amounts of natural gas that could pose a serious threat to the Gulf of […]
Global atmospheric concentrations of carbon dioxide, methane, nitrous oxide, and certain manufactured greenhouse gases have all risen substantially in recent years. • Before the industrial era began around 1780, carbon dioxide concentrations measured approximately 270–290 ppm. Concentrations have risen steadily since then, reaching 387 ppm in 2009—a 38 percent increase. Almost all of this increase […]
(AFP) Recently a team from Russia, the US, and Sweden found that the East Siberian Arctic Shelf (ESAS) is releasing around 8 teragrams of methane from subsea sediments each year. Now team member Natalia Shakhova and colleague Dmitry Nicolsky have come up with a new model for the Dmitry Laptev Strait region of the shelf […]
28 Mar 2010, 0101 hrs IST, PTI BANGALORE: Himalayan glaciers retreated by 16% in the last nearly five decades due to climate change, investigations by India’s scientists in selected basins in four states has revealed. The retreat of Himalayan glaciers and loss in a real extent were monitored in selected basins in J&K, Himachal […]
Global meat production has tripled in the past three decades and could double its present level by 2050, according to a new report on the livestock industry by an international team of scientists and policy experts. The impact of this “livestock revolution” is likely to have significant consequences for human health, the environment and the […]
CO2 is the single most important human-emitted greenhouse gas in the atmosphere, contributing 63.5 %(2) to the overall global radiative forcing. However, it is responsible for 85% of the increase in radiative forcing over the past decade and 86% over the last five years. For about 10,000 years before the industrial revolution, the atmospheric abundance […]
Reporting by Timothy Gardner; Editing by Eric WalshWASHINGTONFri Feb 5, 2010 6:08pm EST (Reuters) – Arctic ice melting could cost global agriculture, real estate and insurance anywhere from $2.4 trillion to $24 trillion by 2050 in damage from rising sea levels, floods and heat waves, according to a report released on Friday. “Everybody around the […]
Summertime observations of dissolved CH4 in the East Siberian Arctic Shelf (ESAS) (21). … (D) Fluxes of CH4 venting to the atmosphere over the ESAS. Remobilization to the atmosphere of only a small fraction of the methane held in East Siberian Arctic Shelf (ESAS) sediments could trigger abrupt climate warming, yet it is believed that […]
By David A. FahrentholdWashington Post Staff WriterMonday, March 1, 2010 Nearly 40 years after the first Earth Day, this is irony: The United States has reduced the manmade pollutants that left its waterways dead, discolored and occasionally flammable. But now, it has managed to smother the same waters with the most natural stuff in the […]
By Michael FitzpatrickScience reporter, BBC News Scientists have uncovered what appears to be a further dramatic increase in the leakage of methane gas that is seeping from the Arctic seabed. Methane is about 20 times more potent than CO2 in trapping solar heat. The findings come from measurements of carbon fluxes around the north of […]
