Researchers argue carbon offset hopefuls have jumped the gun in touting seaweed’s carbon-sucking potential.

Countries must urgently agree to a way of controlling and regulating attempts to geoengineer the climate, the former head of the World Trade Organization says.

Research published in the journal Science Advances on Wednesday found wildfires in North American boreal forests could represent about three per cent of global carbon dioxide emissions under the Paris Climate Agreement’s budget to limit warming below 1.5 C.

The federal natural resources minister said on Tuesday, April 26, 2022, that concerns from the auditor general’s office about government plans to move to a more hydrogen-powered economy don’t mean the goals aren’t achievable.

Official plans call for boosting coal production capacity by 300 million tons this year, according to news reports. That is equal to 7% of last year’s output of 4.1 billion tons, which was an increase of 5.7% over 2020.

President Joe Biden is taking steps to restore national forests that have been devastated by wildfires, drought and blight, using an Earth Day visit to Seattle to sign an executive order protecting some of the nation’s largest and oldest trees.

Last week, the federal government announced Canada’s 2020 greenhouse gas emissions dropped, in part thanks to trees removing carbon from the atmosphere. However, environmentalists are quick to point out this calculation excludes a huge chunk of emissions from the logging industry.

Companies want to build pipelines to capture and store carbon, but a new report warns that regulators aren’t prepared.

Climate scientists say plugging methane leaks and phasing out fossil fuels is necessary to avert catastrophic global heating.

"I am of the opinion that the project, as currently proposed, would likely cause unacceptable environmental effects within federal jurisdiction," Environment and Climate Change Minister Steven Guilbeault wrote.

Global atmospheric levels of the potent but short-lived greenhouse gas methane increased a record amount last year, the National Oceanic and Atmospheric Administration said on Thursday, February 7, 2022, worrying scientists because of the large role methane has in climate change.

An appeals court on Tuesday, March 15, 2022, overturned a groundbreaking ruling that Australia’s environment minister had a duty to protect younger people against climate change.

They say that carbon capture and storage has the potential to make a big dent in cutting pollution, while creating sustainable jobs and economic growth across the country.

Climate change is already killing people, but countries don’t have an easy way to count the true mortality cost of carbon. A new project might change that.

The Solid Carbon initiative aims to scrub vast amounts of carbon dioxide (CO2) from the air before pumping it into basalt reservoirs below the ocean floor, where it will transform into rock.
