“How we confront the climate crisis will determine a lot about the next 250 years of American history, including if we make it that long,” one climate advocate said. “The revolution we need today is the clean energy revolution.”

COMMON DREAMS
The US reliance on and promotion of fossil fuels is interfering with its ability to celebrate its 250th birthday, as several July 4 events were canceled due to a dangerous, record-breaking heatwave in the Central and Eastern US that scientists say would have been “virtually impossible” without the climate emergency.
As millions of people sweltered under heat alerts, extreme heat and humidity led to the cancellation of both Washington, DC and Philadelphia’s Independence Day parades. Nearly 30 other events in states including Alabama, Delaware, New Jersey, New York, Pennsylvania, Maryland, and Virginia were modified, postponed, or canceled, according to USA Today.
“The US having to cancel major 4th of July celebrations because of extreme heat is almost too spot on as a metaphor for the country’s failure to combat global warming,” Fossil Free Media director Jamie Henn told Common Dreams. “How we confront the climate crisis will determine a lot about the next 250 years of American history, including if we make it that long. The revolution we need today is the clean energy revolution so we can finally declare our independence from fossil fuels.”
Temperature records were tied or broken in 22 locations on Thursday and 17 on Friday, according to CNN, with DC breaking a 120-year record on both days with temperatures above 102°F.
The heat forced the temporary closure Friday afternoon of the Great American State Fair on the National Mall, and seven attendees required “advanced life support,” probably due to heat exposure, according to CNN.
Matt Rein, the Democratic National Committee’s influencer and creative partnerships director, reported from the state fair on Saturday that local emergency workers said guests were “dropping like flies” due to the heat.
Meanwhile, one group who tried to draw attention to the climate emergency at a July 4 event was evicted for its efforts by the US Coast Guard, as the Times Union reported. The nonprofit Hudson River Sloop Clearwater had attempted to join Saturday’s Sail4th 250 parade of tall ships to New York Harbor when its sailboat was removed by the guard. The Coast Guard later said it was due to banners the boat was displaying reading, “Save the Clean Water Act” and “Indigenous rights, racial justice, climate solutions,” despite the fact that the group had the event organizer’s permission to participate.
The heat dome that has settled over the Central and Eastern US over the July 4 weekend is so dangerous in part because it includes high humidity along with high heat, with heat indexes of 105-115°F expected in some places. This corresponds with a Wet Bulb Global Temperature (WBGT)—a measurement that accounts for heat, humidity, and air flow—of 28-30°C, at which point it is dangerous for even healthy people to be physically active outdoors. According to World Weather Attribution, the current heatwave broke regional records for WBGT.
“It is still a relatively rare event even in today’s climate, that has warmed by 1.4°C due to the burning of fossil fuels. In a 1.4°C cooler climate, WBGTs as high as those forecast in early July 2026 would have been so extreme as to be virtually impossible,” the group wrote on Friday.
Friederike Otto, a professor of climate science at Imperial College London, told CNN, “When a historic 4th of July celebration is disrupted, and World Cup matches are played in conditions that are unsafe for players and fans, it shouldn’t take another scientific study to wake people up.”
Otto continued, “Climate change is here, it’s already impacting the things we enjoy in our everyday lives, and it will continue to get worse the longer we drag out the inevitable transition to net zero emissions.”
Climate scientist and communicator Katharine Hayhoe encouraged people to use this opportunity to talk about the climate emergency to their friends and family:
Heatwaves aren’t new. But I’m a climate scientist, and I can tell you heatwaves like this are virtually impossible without fossil fuel pollution. Not only that, but when extreme weather hits, research shows that connecting it to climate change helps people understand why it matters. And you know who the most trusted people to do that are? Not scientists. You! Yes, people we know are the most effective messengers to have these conversations. So if you’re worried about what’s happening and how extreme heat puts us at risk—talk about it!
While the US is the world’s leading historical emitter of greenhouse gas emissions, and its military is the No. 1 institutional climate polluter, the Trump administration in particular has taken steps to accelerate the climate emergency by increasing oil, gas, and coal production while hindering the development of renewable energy.
“Trump’s promotion of coal burning and cancellation of wind turbines make him the Benedict Arnold of America’s current struggle, not its George Washington.”
Just two days before the nation’s birthday, Energy Secretary and fracking CEO Chris Wright bragged on social media that the Trump administration would end subsidies for new wind and solar on July 4.
Climate scientist Rebekah Jones shot back: “During a record heatwave, no less. Fossil fuel industries have received $549 BILLION in direct subsidies, and $7 TRILLION in tax benefits. They average $30 billion per year in upfront taxpayer money. All of renewable energy recieved $400 million per year from 1994-2009.”
Tennessee state Sen. Heidi Campbell (D-20) also called out the move: “Talk about ‘slugs for salt’—it’s 119 degree heat index in the Eastern US this week—these guys are all in on the rapture.”
In a July 4 post, scholar Juan Cole argued that President Donald Trump’s climate policies were tantamount to treason.
“Since 2018, some 13,000 Americans have died from heat,” he said. “Trump’s promotion of coal burning and cancellation of wind turbines make him the Benedict Arnold of America’s current struggle, not its George Washington.”
Cole pointed out that the current heatwave was part of a pattern of hotter summers in the nation’s capital due to the climate emergency, noting that the last decade was its hottest on record.
He continued:
The bad news is that this is only the beginning. Summers in the capital are going to be more dangerous every decade unless we halt dangerous carbon emissions.
The average summer temperature in DC could be 97°F in the 2080s if we go on farting out CO2 at our current rate. Humidity will also increase, as the Atlantic heats up and puts more water vapor in the atmosphere. The ability of the atmosphere to hold water vapor increases 7% with every 1°C increase in temperature.
That combined with more frequent storms and sea-level rise opens up the possiblity that DC “will be unlivable in the summers within the lifetime of my younger readers,” he wrote.
“Trump is helping climate change accomplish what British military might could not, putting in question the future of America in places like Washington, DC and Baltimore, at least in the summers,” Cole said.
