Earth Day is tomorrow one of the key events in the environmental movement.

It comes as a federal judge has temporarily blocked the EPA from canceling $14 billion in climate grants approved by the Biden administration,

marking a setback to President Trump's agenda to freeze climate spending across the government.

As part of our tipping point series, William Brangham

spoke recently with the leading environmentalist about the opposition to Mr. Trump's plan for the

climate.

2024 was the hottest year on record, capping a decade where almost every year broke the previous

year's record high. Carbon emissions, which helped drive that

warming, are also at record levels. President Trump and his administration argue that this is not a

problem, and that trying to address it only hurts the economy and puts the U.S. at a competitive

disadvantage. On his first day in office, President Trump withdrew the U.S. from the Paris Climate Accord.

He's tried to freeze billions in funding for clean energy projects, wants to boost coal production,

and declared a, quote, national energy emergency to increase domestic fossil fuels.

While Trump's actions face legal challenges,

environmentalists are sounding the alarm.

And among them is Bill McKibben.

He's the author of several books on climate change,

the founder of the grassroots climate campaign called 350.org,

and Third Act, which organizes older Americans

to work on climate justice.

Bill McKibbin, great to have you on the program.

What are some of your greatest immediate concerns about the Trump administration?
