Critics warn of climate danger as president in Texas claims change will save companies and consumers billions

Donald Trump said his administration is “terminating” Biden-era regulations holding oil and gas companies accountable for large leaks of planet-warming methane during a rally in Lubbock, Texas, on Tuesday evening.

“Tonight, I’m officially terminating Biden’s expensive and unnecessary methane regulations to save consumers and energy producers,” Trump said, lifting what he called “crippling regulations on methane that caused prices to skyrocket” for small oil and gas operators. The change would save consumers and energy producers $45bn and unlock 210m barrels of oil, he said, which is equivalent to about 10 days of US petroleum consumption.

Firms manage $7.3tn in assets and could afford to transition away from fossil fuels yet invest in natural gas and coal-fired plants to power datacenters

The energy portfolios of 20 private equity firms produce 1.5bn tons of greenhouse gases a year, more than the annual emissions of any country except China, the US, India and Russia, according to a new report.

Together, these firms manage $7.3tn in assets of all kinds, affording them the ability to shape the pace of the transition away from fossil fuels. However their energy investments include significant fossil fuel assets including natural gas and coal-fired power plants to provide electricity to datacenters.

Officials have had to remove thousands of tons of sargassum from Florida’s beaches amid the climate crisis

Dealing with seaweed is the bulk of Chris Bumpus’s job during the summer. As chief of conservation for Miami-Dade county’s parks, recreation and open spaces department, Bumpus is in charge of cleaning sargassum off 17 miles (27km) of county beaches. But some days, the odds are stacked against him and his team.

More and more sargassum, a kind of floating brown algae, has been washing up on the beaches of south Florida, west Africa, the Gulf of Mexico and the Caribbean.
