At the brink of what may be the hottest summer on record, the Texas oil and gas industry is pumping out planet-heating fuels at record levels, a new report has found.

Estimates from the Texas Oil and Gas Association (TXOGA) released Monday found the state umped out a record 5.7 million barrels per day of crude oil in May, and it sold a record 32 billion cubic feet of gas.

Those record numbers come out as much of the U.S. experiences its longest heat wave in decades, with more than 135 million Americans at risk from extreme heat. Climate change caused by the burning of fossil fuels is making heat waves longer and hotter, according to conservative climate advocacy group C-Change Conversations. 

The May TXOGA estimates come on top of official oil and gas production numbers out this week from the U.S. Energy Information Agency (EIA).

The EIA found that Texas produced 28.2 billion cubic feet of methane gas per day in March — less than half of which was used by the state’s consumers.

Texas-based industry and the state power grid used 12.5 billion cubic feet — 44 percent — of the total gas produced in March, with most of the rest going to export. 

Those exports netted the industry an estimated $56.8 billion from January to March, according to the EIA.

Because it burns cleaner than coal, natural gas’s supporters have for decades touted it as a greener alternative to other fossil fuels and argued it is a more climate-friendly energy source to lean on amid the transition to renewables. But it has raised concerns from environmentalists and communities near terminals, largely due to leaks at the wellhead and along pipelines.
