President Trump is carrying out his pledge to give the U.S. a MAGA makeover by signing a slew of executive actions in his first week that walk back Biden-era policies and fulfill his campaign promises.

Experts say Trump’s moves to step away from global climate action, ramp up domestic oil and gas production and remove incentives for electric vehicles are worrisome as the planet continues to heat up. 2024 was Earth’s hottest year on record, and climate scientists say the rising heat is contributing to extreme weather affecting millions.
