Repeal of Clean Energy Law Will Mean a Hotter Planet, Scientists Warn
When President Joseph R. Biden Jr. signed the 2022 Inflation Reduction Act, he called it 'the most aggressive action ever, ever, ever to confront the climate crisis.'
Now, Republicans are poised to undo the law, and scientists are warning the result would increase the likelihood that the Earth will heat up by an average of 3 degrees Celsius above preindustrial levels by the end of this century.
'We're already in an era now where climate change is going to be increasingly dangerous,' said Jonathan T. Overpeck, a climate scientist and the dean of the University of Michigan's School for Environment and Sustainability.
That amount of warming — 3 degrees Celsius (5.4 degrees Fahrenheit) over the course of a century — may sound small. But 2024, the hottest year on record, was the first calendar year where the global average temperature exceeded 1.5 degrees Celsius above preindustrial levels, and it delivered deadly heat, violent hurricanes, severe drought and devastating wildfires.
The Biden administration's strategy to fight climate change consisted of tax breaks to nudge the country toward clean energy and away from fossil fuels, the burning of which is heating the planet, paired with strict limits on pollution from smokestacks and tailpipes.
That would have put the United States on track to cut emissions about 40 percent below 2005 levels by 2035, closer to the goal that scientists say all industrialized nations must meet in order to keep global warming within relatively safe limits. The United States is currently the second biggest emitter of greenhouse gases, behind China. But it is the country that has pumped the most carbon dioxide and other greenhouse gases into the atmosphere since the Industrial Revolution.

Trump says Harvard agreement on international students may be announced within a week
President Donald Trump on Friday said a deal with Harvard University, related to its policies surrounding international students, may be announced within a week. "Many people have been asking what is going on with Harvard University and their largescale improprieties that we have been addressing, looking for a solution," Trump wrote on Truth Social. "We have been working closely with Harvard, and it is very possible that a Deal will be announced over the next week or so." The president noted the university "acted extremely appropriately" during negotiations, applauding leadership's apparent commitment to do "what is right." "If a Settlement is made on the basis that is currently being discussed, it will be "mindbogglingly" HISTORIC, and very good for our Country," Trump wrote. The announcement came as Federal Judge Allison Burroughs on Friday issued a preliminary injunction, allowing Harvard University to continue hosting international students, despite a Trump executive order. It is a major legal victory for the Ivy League school, which has been fighting a variety of restrictions imposed by the administration. The temporary court order stays in effect until the case is fully decided on the merits. Harvard University sued the Department of Homeland Security (DHS), challenging the revocation of Harvard's Student and Exchange Visitor Program (SEVP). Without the program, current and future international students would be barred from attending the university. Harvard alleged the revocation was the culmination of a retaliatory campaign by the Trump administration on academic freedom at Harvard. Attorneys argued the policy is an infringement of the university's Due Process and First Amendment rights, in particular Harvard's constitutional right to be free of retaliatory action for protected speech, as well as violating the Administrative Procedures Act (APA). The order states the revocation cannot be used to negatively affect visa applications, deny entry to the U.S., or be used as a reason to claim a visa holder has lost their non-immigrant status. Harvard University did not immediately respond to Fox News Digital's request for comment.
