A Climate Denier is Leading the NASA Transition

A Climate Denier is Leading the NASA Transition

Scientists and policy watchers have been sounding the alarm bell that NASA’s climate work could be in jeopardy ever since Donald Trump’s election last month. That’s due in large part to some of his advisors saying the agency should be focused on space exploration and not wasting money observing the earth. But the alarm started ringing louder last … Read More

Scientists Take Big Step Toward Safely Burying CO2

Scientists Take Big Step Toward Safely Burying CO2

For the first time, scientists have injected carbon dioxide into ancient lava flows and watched it solidify, demonstrating that capturing carbon dioxide from the atmosphere or a power plant smokestack and safely storing it underground may be a realistic way to help reduce greenhouse gas emissions to tackle climate change.… Read More

Sewage Plants Overlooked Source of CO2

Sewage Plants Overlooked Source of CO2

Wastewater treatment plants may be responsible for emitting up to 23 percent more greenhouse gas than previously thought because of fossil fuels in detergent-laden water from residential showers, household washing machines and industrial sites, new research shows. Treatment plants emit greenhouse gases such as methane and nitrous oxide when they… Read More

Drought, Climate Impact Fall Foliage in Complex Ways

Drought, Climate Impact Fall Foliage in Complex Ways

The riot of colors that erupts on trees each fall drives billions of dollars in tourism and remains a key way for people to connect with nature. But that simple transition from summer’s lush greens to fall’s brilliant reds, oranges and yellows can be impacted in surprisingly complex ways by weather and climate, and those effects may be even more… Read More

Carbon Dioxide Passed Critical Threshold in 2015

Carbon Dioxide Passed Critical Threshold in 2015

On Monday, the World Meteorological Organization released another reminder of the planetary predicament we’re in: The earth’s atmosphere officially passed the 400 parts per million (ppm) threshold permanently last year. It’s the first year in human history where carbon dioxide levels have reached the symbolic milestone for an entire year. But it … Read More

Scientists Warn Negative Emissions Are a ‘Moral Hazard’

Scientists Warn Negative Emissions Are a ‘Moral Hazard’

Removing carbon dioxide emissions from the atmosphere to prevent global warming from becoming catastrophic may be a fool’s game amounting to a “moral hazard par excellence,” according to a paper published Thursday in the journal Science. Nobody knows if atmospheric carbon removal — known as negative emissions — will work, and it could delay … Read More

Record Warmth Helps Shrink U.S. Carbon Emissions

Record Warmth Helps Shrink U.S. Carbon Emissions

Energy related carbon dioxide emissions hit their lowest point since 1991 during the first six months of 2016 because of mild weather, declining coal use and increased use of wind, solar and hydropower. By the end of the year, 2016 is expected to see the lowest level of energy related carbon emissions of any full year since 1992.… Read More

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
