Current conditions: A heat wave triggered power cuts in Kuwait as electricity demand exceeded capacity • Australia just rounded out its 12 hottest months ever recorded • Temperatures in New York City are forecast to reach 73 degrees Fahrenheit today, nearly 30 degrees higher than yesterday.

THE TOP FIVE

1. Severe storms threaten millions with ‘generational’ flooding

Powerful thunderstorms are tearing across the Midwest and Mississippi Valley in what the National Weather Service has warned will be a “multi-day catastrophic and potentially historic” event. Destructive and deadly tornadoes were reported overnight in multiple states including Missouri, Arkansas, Kentucky, and Indiana. The system also brought a threat of once-in-a-lifetime flooding caused by heavy rainfall. More than 1.4 million people were under flash flood warnings. “This isn’t routine,” the National Weather Service in Memphis, Tennessee, warned. “This is a rare, high-impact, and potentially devastating event.” The storm is expected to stall over the region and continue to dump heavy rain – up to 12 inches in some areas – through the rest of the week.

As Heatmap’s Jeva Lange has reported, the Intergovernmental Panel on Climate Change is highly confident in the attributable influence of climate change on extreme rain, and “everything we know about thunderstorms suggests that a warmer, wetter atmosphere will mean severe convection storms become both more frequent and more intense.” These historic spring storms are hitting as the Trump administration slashes jobs at the National Oceanic and Atmospheric Administration and the Federal Emergency Management Agency, hampering the government’s ability to effectively forecast and respond to weather emergencies.

2. Trump rolls out reciprocal tariffs

President Trump on Wednesday announced sweeping 10% baseline tariffs on imported goods, as well as higher “reciprocal” tariffs against about 60 countries that impose charges and other trade barriers on U.S. products. China will be hit with a 34% reciprocal fee, on top of Trump’s existing 20% tariffs on Chinese goods, bringing the overall rate to 54%. The European Union will be hit with 20% reciprocal tariffs; India 26%; South Korea 25%; Japan 24%, and Vietnam 46%. The full list is here.

The newly announced levies exclude imported energy commodities such as crude oil, natural gas, and refined products. “The exemption will come as a relief to the U.S. oil industry, which had expressed concerns that new levies could disrupt flows and raise costs,” Reutersnoted. Meanwhile, high reciprocal tariffs on goods from southeast Asia mean higher prices for solar panels, “another potential dent to the clean energy buildout by a president keen to boost fossil fuels,” according toBloomberg. Trump’s 25% tariffs on auto imports also come into effect today, a move expected to hike car prices for American consumers.

3. Tesla shares rebound on rumor of Musk’s White House departure

Tesla’s shares have been on a rollercoaster ride over the last 24 hours, falling by about 6% on weak quarterly EV sales, then rebounding on a report that CEO Elon Musk plans to step away from his role within the Trump administration. The electric vehicle company delivered 336,681 cars in the first quarter of 2025, far below analyst expectations of 390,000. The results are the company’s weakest since 2022, a further sign of curdling consumer sentiment as Musk spearheads unpopular mass firings across multiple federal agencies as head of the Department of Government Efficiency. On Wednesday, Politicoreported that President Trump has been telling his Cabinet that Musk will soon “return to his businesses and take on a supporting role” within the administration. The White House denied the report, but the rumor seemed to buoy Tesla’s stock market position, with pre-market shares up about 5% on Thursday.

4. Republican state lawmakers urge Wright not to cut hydrogen hub funding

A group of 16 Republican state legislators on Wednesday sent a letter to Energy Secretary Chris Wright asking him not to pull the plug on funding for seven nascent hydrogen hubs dotted across the country. The Department of Energy is reportedly thinking about cutting $4 billion in funding for the hubs, which were approved under the Biden administration in an effort to turn hydrogen into a viable fossil fuel alternative. The GOP lawmakers urge Wright to preserve funding for the Pacific Northwest Hydrogen Hub in particular, pitching it as a boost to manufacturing, energy independence, and domestic economic growth. Senate Democrats sent their own letter to Wright on Wednesday slamming the contemplated hydrogen hub defunding. “Indiscriminately canceling program funding and executed contracts, and refusing to execute on the funding directives Congress enacted, neither honors existing agreements nor is consistent with the spending laws that have appropriated funding for specific purposes,” the Democrats wrote.

5. Report: Global coal use is up, especially in India and China

Global coal-fired power capacity additions in 2024 were at their lowest level in 20 years, according to a new report from the Global Energy Monitor. The drop signals an ongoing slowdown in coal use as renewables come online, but the fleet is still growing, especially in China and India. China’s 30.5 gigawatts of newly commissioned coal power capacity last year accounted for 70% of the global total. Meanwhile, India recorded more new coal proposals than ever before. Coal is one of the dirtiest fossil fuels, accounting for 40% to 45% of global energy-related carbon dioxide emissions.

THE KICKER

Montana’s Colstrip power plant, which produces more fine particulate emissions than any other coal-burning plant in the United States, has asked President Trump for an exemption from the Environmental Protection Agency’s air pollution standards.

The Climate Election You Missed Last Night

While you were watching Florida and Wisconsin, voters in Naperville, Illinois were showing up to fight coal.

It’s probably fair to say that not that many people paid close attention to last night’s city council election in Naperville, Illinois. A far western suburb of Chicago, the city is known for its good schools, small-town charm, and lovely brick-paved path along the DuPage River. Its residents tend to vote for Democrats. It’s not what you would consider a national bellwether.

Instead, much of the nation’s attention on Tuesday night focused on the outcomes of races in Wisconsin and Florida — considered the first electoral tests of President Donald Trump and Elon Musk’s popularity. Outside of the 80,000 or so voters who cast ballots in Naperville, there weren’t likely many outsiders watching the suburb’s returns.

The Department of Energy is moving ahead with plans to allow companies to build AI data centers and new power plants on federal land — and it has put together a list of more than a dozen sites nationwide that could receive the industrial-scale facilities, according to an internal memo obtained by Heatmap News.

The memo lists sites in Texas, Illinois, New Jersey, Colorado, and other locations. The government could even allow new power plants — including nuclear reactors and carbon-capture operations — to be built on the same sites to generate enough electricity to power the data centers, the memo says.

Current conditions: A rare wildfire alert has been issued for London this week due to strong winds and unseasonably high temperatures • Schools are closed on the Greek islands of Mykonos and Paros after a storm caused intense flooding • Nearly 50 million people in the central U.S. are at risk of tornadoes, hail, and historic levels of rain today as a severe weather system barrels across the country.

THE TOP FIVE

1. Trump to roll out broad new tariffs

President Trump today will outline sweeping new tariffs on foreign imports during a “Liberation Day” speech in the White House Rose Garden scheduled for 4 p.m. EST. Details on the levies remain scarce. Trump has floated the idea that they will be “reciprocal” against countries that impose fees on U.S. goods, though the predominant rumor is that he could impose an across-the-board 20% tariff. The tariffs will be in addition to those already announced on Chinese goods, steel and aluminum, energy imports from Canada, and a 25% fee on imported vehicles, the latter of which comes into effect Thursday. “The tariffs are expected to disrupt the global trade in clean technologies, from electric cars to the materials used to build wind turbines,” explained Josh Gabbatiss at Carbon Brief. “And as clean technology becomes more expensive to manufacture in the U.S., other nations – particularly China – are likely to step up to fill in any gaps.” The trade turbulence will also disrupt the U.S. natural gas market, with domestic supply expected to tighten, and utility prices to rise. This could “accelerate the uptake of coal instead of gas, and result in a swell in U.S. power emissions that could accelerate climate change,” Reutersreported.
