This summer, the world has been treated to a stark reminder of the devastating impact of climate change. From the eerie sepia skies of the northeastern US to the deadly wildfires in Canada and the flash floods in Texas, the signs of a changing climate are all around us. But what makes this summer particularly fascinating is how these events are compounding each other, creating a cascade of disasters that are both shocking and deeply concerning. In my opinion, this is a critical moment that demands our attention and action. Let's take a closer look at what's happening and why it matters.
The Summer of Compounding Disasters
The summer of 2026 has been a stark reminder of the dire warnings scientists have been issuing for decades. From torrid heat waves to deadly flash floods to raging wildfires, the signs of climate change are no longer just theoretical but very real and very present. This is not a future scenario but a current reality, and it's happening right before our eyes. What makes this particularly fascinating is how these events are compounding each other, creating a cascade of disasters that are both shocking and deeply concerning.
One of the most striking examples is the wildfire smoke that has engulfed cities from Washington, DC, to Boston. The air has smelled like smoke, even hundreds of miles downwind from the blazes. Sunsets have been transformed into an ethereal red, while the sun has been barely visible at noon through the pollution. This is not just a local issue; Midwestern cities like Chicago and Detroit have had some of the worst air quality in the world. At one point last week, at least 120 million Americans from Minnesota to Massachusetts were under air quality warnings due to the wildfire smoke.
The Science Behind the Disasters
For decades, scientists have been warning us about the calamitous consequences of climate change. These warnings have often come in scientific studies using seemingly far-off years such as 2050 and 2100. But this summer proves we don’t have to wait until the future for climate change to smack us in the face. The burning of fossil fuels is already having a clear and significant impact on communities, and we do not have to wait until 2050 or 2100 to see the consequences. This is a critical moment that demands our attention and action.
The extreme weather and climate events so far this summer read like an over-the-top disaster movie script, except this is reality. Parts of Texas are reeling from flash flooding after a deadly, 1,000-year rainfall event — the second in just two years. Such events have a 0.1% chance of occurring in any single year, under normal circumstances. But extreme rainfall is becoming more common as planet-warming pollution pushes temperatures higher because warmer air holds more moisture. In some parts of Texas Hill Country, nearly an entire year’s worth of rain fell last week, leading to dangerous flood waves coursing through the often-parched terrain.
The Heat Wave and Its Impact
Meanwhile, hundreds of millions of people in the US and Europe have sweltered beneath relentless heat domes that have resulted in thousands of excess deaths in Europe alone. These sprawling areas of strong high pressure act like a lid on the atmosphere, trapping heat underneath and squelching clouds and precipitation with their sinking air. In Western Europe, a succession of heat domes in May, June, and July turned verdant landscapes into tinderboxes, with deadly wildfires sweeping across Spain, France, the UK, and other countries where wildfires were once considered rare. Water shortages are emerging in the Netherlands and could soon manifest elsewhere.
America’s recent heat waves shattered a bevy of all-time, monthly, and daily high temperature and overnight minimum temperature records, some by large margins. Thermometers in normally cooler states such as Montana and Minnesota have registered temperatures so high that they blasted through longstanding all-time records, with triple-digit high temperatures in mid-July extending all the way to the Canadian border. Temperatures in parts of Montana climbed into the 110s.
The Compound Effect
Scientists long ago sounded the alarm that when climate disasters come, they won’t necessarily happen one at a time. Instead, there would be an uptick in compound disasters, as one extreme piles upon another. And that is exactly what has happened this summer. These overlapping hazards can lead to greater economic losses, more serious health impacts, added stress on infrastructure, and further damage to ecosystems. The heat, flooding, wildfires, and resulting smoke have coincided with the release of a new, authoritative report from the National Academy of Sciences on attributing extreme weather events to climate change, and how far that research has come in just the past few years.
The Political Landscape
It is possible that this cruel summer of floods, heat waves, and wildfires will cause people to reevaluate their stance on climate issues. Some polls have shown movement toward greater support for climate action among survivors of climate disasters. A 2025 Pew survey found that 74% of Americans said they’ve experienced at least one of five forms of extreme weather, such as heat waves and floods, in the past year. A majority of that 74% said they viewed climate change as a contributor to the extreme weather, and this was particularly the case for heat waves. However, the same poll found partisanship shapes people’s perceptions. Republicans tended to be less likely than Democrats to see a strong connection between an extreme weather event that they experienced and climate change.
The Way Forward
In short, while this summer’s disasters may make people more aware of climate change, they’re unlikely to move the political needle. But it’s just a preview of what’s to come if the burning of fossil fuels is not rapidly and drastically curtailed. We are indeed seeing the consequences of climate inaction. It would be a mistake to think that the climate crisis has reached a ‘new normal,’ since the world continues to warm as fossil fuel pollution piles up in the atmosphere. I prefer the term ‘new abnormal’ instead. It’s an ever-shifting baseline toward more extreme conditions as long as we continue to warm the planet with carbon pollution. We need to get off at the next possible exit before we crash.
In conclusion, this summer has been a stark reminder of the devastating impact of climate change. From the eerie sepia skies to the deadly wildfires and flash floods, the signs of a changing climate are all around us. It's time to take action and make a difference. The future of our planet depends on it.
