A Cooler Future May Hinge on Removing CO2 From the Air

A Cooler Future May Hinge on Removing CO2 From the Air

Climate pollution equal to about 27 times humans’ 2015 carbon dioxide emissions may have to be removed from the atmosphere and locked underground forever in order to keep the globe from warming beyond 1.5°C (2.7°F) above preindustrial levels, according to a new study. The research, led by scientists at the International Institute for Applied … Read More

Harvard Scientists Taking Geoengineering Into the Field

Harvard Scientists Taking Geoengineering Into the Field

Geoengineering has been a topic on the fringe of climate discussions for more than a decade, but it’s been edging ever closer to the mainstream as carbon pollution rises. It’s slated to take a step closer still later this year, with a group of Harvard scientists planning a small scale experiment. Their test will redirect the sun’s rays back into s… Read More

Senate Mulls ‘Kill Switch’ for Obama Methane Rule

Senate Mulls ‘Kill Switch’ for Obama Methane Rule

The U.S. Senate is expected to vote soon on whether to use the Congressional Review Act to kill an Obama administration climate regulation that cuts methane emissions from oil and gas wells on federal land. The rule was designed to reduce oil and gas wells’ contribution to climate change and to stop energy companies from wasting natural gas. The… Read More

Public Climate Information Threatened Under Trump

Public Climate Information Threatened Under Trump

Websites maintained by the federal government are among the first online stops for the general public — from students, local policymakers and everyone else — to learn about climate change. There is rising concern among scientists and climate communications experts that those websites may be among the first to be deleted, politicized or degraded … 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

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

Artificial Leaf Turns CO2 Emissions Into Fuel

Artificial Leaf Turns CO2 Emissions Into Fuel

If humans could invent a leaf-like solar cell that could turn carbon dioxide pollution from the atmosphere into fuel for electric power plants, it could help reduce reliance on fossil fuels and cut emissions that contribute to global warming. That’s the goal of a new artificial leaf that a team of researchers led by the University of … Read More

Court Decision on Climate Plan Jolts Carbon Prices

Court Decision on Climate Plan Jolts Carbon Prices

A temporary halt to the federal government’s plan to cut electric power plant emissions has caused carbon prices in the Northeast’s only cap-and-trade program to plummet, according to the U.S. Department of Energy. Carbon prices in the Regional Greenhouse Gas Initiative, or RGGI, have fallen 40 percent since the Supreme Court’s decision in … Read More
