What happened: The US Environmental Protection Agency, under the Trump administration, has overturned a landmark ruling that classified greenhouse gases as a threat to public health. This decision removes a major regulatory basis for climate change policies.
Why it matters:
- It weakens federal authority to regulate emissions contributing to global warming.
- It affects efforts to reduce pollution and protect public health across the US.
MNN Take: The EPA's reversal changes how greenhouse gases are legally viewed, potentially limiting future climate action under US law.
