CO2, Climate Change Seen As Waste Disposal Challenge

CO2, Climate Change Seen As Waste Disposal Challenge

When it comes to carbon dioxide, what goes up doesn’t come down. It stays in the atmosphere for thousands of years after plumes of pollution have been released from tailpipes and power plants, trapping heat and warming the planet. That’s why some scientists are increasingly looking at global warming as a waste disposal problem. They say that think… Read More

Michigan Scientists See Urgency for Negative Emissions

Michigan Scientists See Urgency for Negative Emissions

Beyond Carbon Neutral at the University of Michigan is one of several university programs across the country investigating potential ways of taking large-scale negative emissions out of the theoretical realm and into the real.… Read More

North American Forests Not a Climate Change Remedy

North American Forests Not a Climate Change Remedy

North American forests will not fight climate change by absorbing carbon dioxide at levels once hoped for because the trees may not grow big enough, a study said. The new research challenges previous studies that said trees could grow larger due to higher temperatures brought on by global warming, said the authors of the study published in the… Read More

Negative Emissions Key to Meeting 2°C Threshold

Negative Emissions Key to Meeting 2°C Threshold

Humans will have to not only stop emitting greenhouse gases by 2085, but also develop technology that will result in negative emissions — the removal of 15 billion tons of carbon dioxide from the atmosphere each year by the end of the century — in order to prevent global warming from exceeding 2°C (3.6°F), according to a new study. … Read More

‘Water Windfall’ Found in Drought-Stricken California

‘Water Windfall’ Found in Drought-Stricken California

California’s Central Valley has three times more freshwater in underground aquifers than previously thought, drinking water that could help the state weather future drought and fortify itself against a changing climate, according to a new Stanford University study. But tapping that water, locked thousands of feet beneath the ground, will be … Read More

Scientists Turn Carbon Dioxide Emissions to Stone

Scientists Turn Carbon Dioxide Emissions to Stone

For the first time, carbon dioxide emissions from an electric power plant have been captured, pumped underground and solidified — the first step toward safe carbon capture and storage, according to a paper published Thursday in the journal Science. “This opens another door for getting rid of carbon dioxide or storing carbon dioxide in the … Read More

Spike in Alaska Wildfires is Worsening Global Warming

Spike in Alaska Wildfires is Worsening Global Warming

The devastating rise in Alaska’s wildfires is making global warming even worse than scientists expected, U.S. government researchers said. The sharp spike in Alaska’s wildfires, where more than 5 million acres burned last year, are destroying a main buffer against climate change: the carbon-rich boreal forests, tundra and permafrost that have… Read More

Warming Could Boost Carbon Storage in Alaska Forests

Warming Could Boost Carbon Storage in Alaska Forests

Climate change may dramatically increase carbon storage in Alaska’s temperate forests, possibly offsetting the climate impacts of melting permafrost and wildfires, new research from the U.S. Geological Survey shows. But there’s an asterisk: the study’s authors said their projections could be skewed by a lack of data on methane emissions from lakes… Read More
