Food becoming more calorific but less nutritious due to rising carbon dioxide

However, zinc in chickpeas would be expected to plummet by up to 37.5%, with a "significant" decrease in protein, zinc and iron in essential crops such as rice and wheat. The researchers warned of "devastating health consequences" including "hidden hunger, where people have sufficient food calorically but insufficient nutrients"...

EPA seeks to repeal finding that carbon dioxide emissions threaten public health

The Trump administration is seeking to repeal a landmark finding that greenhouse gas emissions pose a threat to public health, the head of the Environmental Protection Agency said Tuesday. 

"This has been referred to as basically driving a dagger into the heart of the climate change religion," EPA administrator Lee Zeldin told the conservative "Ruthless Podcast." "Repealing it will be the largest deregulatory action in the history of America," Zeldin said…

Interior Announces Funding for Much-Needed Cleanup of Orphaned Oil and Gas Wells

Orphaned wells have been abandoned by the oil and gas industry, spewing toxic chemicals into the air and water, threatening the health of nearby communities, and emitting large amounts of methane, a greenhouse gas more than 80 times as potent at driving the climate crisis as carbon dioxide...

Industry pushes back against Biden rules on climate disclosure - The Washington Post

If approved, the rules would affect government contractors, insurance firms and other companies and would enable the administration to better track and cap the carbon dioxide and methane emissions that contribute to climate change. It could also transform the purchasing practices of the federal government, which spends about $650 billion each year on goods and services, more than any other entity…

Tropical forests losing their ability to absorb carbon, study finds

Tropical forests are taking up less carbon dioxide from the air, reducing their ability to act as “carbon sinks” and bringing closer the prospect of accelerating climate breakdown. The Amazon could turn into a source of carbon in the atmosphere, instead of one of the biggest absorbers of the gas, as soon as the next decade, owing to the damage caused by loggers and farming interests and the impacts of the climate crisis, new research has found. ....
