A rush to extract methane from the depths of Africa’s Lake Kivu could trigger a huge upwelling of suffocating gas, potentially affecting over 2 million people By Shanta Barley BENEATH the shimmering surface of Africa’s Lake Kivu, a deadly time bomb awaits. A “gold rush” to extract valuable methane from the lake’s depths might trigger […]
By Nina Chestney LONDON (Reuters) – People want to save the planet but are unwilling to make radical lifestyle changes like giving up air travel or red meat to reduce the effects of climate change, a straw poll by Reuters showed. As leaders gear up for another round of climate change talks later this month […]
KODIAK ISLAND, Alaska, August 24, 2009 (ENS) – Billions of tons of carbon are buried in the frozen Arctic tundra, now heating up because of human-caused climate change. To measure which greenhouse gases are being released and in what quantities, government scientists are flying instrument-laden planes over the tundra from now through November. They say […]
The graphs show Iceland Sea winter surface water changes in pH, and the saturation state of aragonite. The anthropogenic increase of atmospheric carbon dioxide affects the Nordic Seas both at the surface and at depth. In the surface, the pH has decreased from 8.13 to 8.08 between 1985 and 2008, and the aragonite saturation, which […]
By Nora Schultz You may have thought that the silver lining of rising carbon dioxide levels would be a boost in crop yields. But evidence is mounting that we may trade quantity for quality. The discovery that staple crops like wheat have less protein when grown in high concentrations of CO2 has already caused concern, […]
At least 45% of Indian land is environmentally “degraded”, air pollution is rising and flora and fauna is diminishing, according to a report. The State of Environment Report is the first to be published for eight years and is the first to use satellite imagery to support its findings. It focuses on water, energy, food, […]
Climate change is speeding up the release of carbon dioxide from frigid peatlands in the sub-Arctic, fuelling a vicious circle of global warming, according to a recently published study. An increase of just 1°C over current average temperatures would more than double the CO2 escaping from the peatlands. Northern peatlands contain one-third of the planet’s […]
By now I’m sure you know that deforestation is a major source of carbon emissions — in fact more than all the fuel burned for transportation — which would be enough to worry about, except that when it comes to emissions from chopping down trees in the Amazon, those emissions are actually increasing as […]
By Art Chimes, Washington, D.C. Rising levels of carbon dioxide in the atmosphere are a major contributor to climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry, potentially threatening marine life. Montana State University scientist Robert Dore has been taking samples of water in the Pacific […]
