Heat, Flooding, and Smoke: The U.S. is in the Midst of a Summer of Extremes

Discover the extreme summer weather in the U.S., from flooding and heatwaves to smoke. Explore the impact of climate change and the urgent need for action.

The summer of [current year] has brought a series of unprecedented and extreme weather events to the United States. From widespread flooding to scorching heatwaves and suffocating smoke, the country is experiencing a summer like never before. Scientists have long warned about the impacts of climate change, and now, we are witnessing their predictions come to life. This article explores the various extreme events occurring across the nation, the link to climate change, and the need for urgent action.

1. Earth’s Hottest Recorded Days

Earlier this month, the Earth experienced its hottest recorded days for average global temperatures. This alarming trend suggests that the influence of climate change, combined with the potential effects of El Niño, is intensifying the background warming.

2. Prolonged Marine Heat Wave

Since mid-March, sea surface temperatures have been exceptionally high, particularly off the coast of Florida. A prolonged marine heat wave has pushed ocean temperatures 5-7 degrees Fahrenheit above normal. This phenomenon has adverse implications for marine ecosystems and contributes to extreme weather events.

3. Unprecedented Wildfires in Canada

Canada has witnessed an unprecedented number of wildfires this year. A record-breaking heatwave in the spring set the stage for these fires, which have already scorched over 37,000 square miles of land. Rising temperatures and changes in fire behavior are predicted to increase the frequency and intensity of wildfires in North America.

4. Smoke Pouring into the U.S.

The wildfires in Canada have sent plumes of smoke into the United States, resulting in the worst year of wildfire smoke exposure per resident since 2006. The presence of smoke poses severe health risks and calls for immediate attention to mitigate the impacts of these catastrophic fires.

5. Severe Heat Wave in Texas

South Texas endured a relentless heatwave that persisted for over two weeks. Locations like Del Rio experienced 18 consecutive days with temperatures exceeding 100°F. These extended heatwaves, fueled by climate change, have become more frequent and intense due to shifting baseline temperatures.

6. Heavy Precipitation and Flooding in the Northeast

The Northeastern region recently faced heavy precipitation, leading to widespread flooding. Cities in Vermont received up to 9 inches of rain in just two days, causing significant damage and disruption. A warmer atmosphere can hold more moisture, increasing the likelihood of extreme rainfall events.

7. The Big Melt of California’s Snowpack

California experienced the melting of its snowpack, resulting in severe flooding across more than 110,000 acres of valuable farmland. The increased water vapor absorption capacity of a warmer atmosphere has contributed to the strength of atmospheric river storms, which can lead to such devastating consequences.

8. Frightening Heat in Phoenix

Phoenix, Arizona, has faced a prolonged heatwave, with temperatures exceeding 110°F for extended periods. Unsheltered residents and vulnerable populations are at significant risk during these extreme heat events. The rising temperatures are a clear indication of the urgent need to address climate change and protect communities.

9. Scientists’ Attribution Studies

Scientists have conducted attribution studies to determine the probability of specific weather events in a cooler climate. These studies have revealed that the heatwave experienced in the Pacific Northwest in June 2021 would have been virtually impossible without the influence of climate change. Such studies highlight the undeniable link between extreme events and the changing climate.

10. Intensifying Pattern of Extremes

The series of extreme weather events witnessed this year is part of a larger pattern that is intensifying over time. While individual events cannot be solely attributed to climate change, the consistency and frequency of these extremes align with scientists’ expectations. The need to address climate change and its impacts is becoming increasingly urgent.

11. Heat Records Falling Outside North America

Extreme heat is not limited to North America. The “Cerberus” heatwave recently gripped Europe, with temperatures in Greece nearing 110°F. The European Space Agency warns that Europe’s all-time high temperature of 120°F could be surpassed in the near future. These records highlight the global nature of extreme weather events.

12. The Global Impact of Extreme Heat

Extreme heatwaves have devastating consequences worldwide. Heat-related deaths in Europe exceeded 61,000 last summer, emphasizing the urgency to address climate change. Japan also experienced new daily rainfall records, further highlighting the global reach of extreme weather phenomena.

13. New Daily Rainfall Records in Japan

Japan’s Kyushu region recently set new daily rainfall records, underscoring the increased frequency of extreme precipitation events. These records serve as a wake-up call to the global community to take immediate action in combating climate change.

14. The Widespread Nature of Record-Breaking Events

Record-breaking events are not isolated occurrences. Many parts of the world are simultaneously experiencing extreme weather and broken records. These prolonged episodes of extreme weather require comprehensive strategies and international cooperation to mitigate their impact and build resilience.

15. The Urgent Need for Climate Action

The pace of climate change has outpaced society’s ability to adapt. The increasing frequency and severity of extreme weather events demand immediate action to reduce greenhouse gas emissions, transition to renewable energy sources, and implement robust adaptation measures. The world must come together to address the root causes of climate change and protect the planet for future generations.


The U.S. summer of extremes serves as a stark reminder of the urgent need to address climate change. Extreme flooding, heatwaves, and smoke events are becoming more frequent and severe, impacting communities across the country. The scientific consensus on the role of climate change in these events is clear, demanding swift action to reduce emissions and build resilience. By prioritizing climate action, we can mitigate the devastating consequences of extreme weather events and ensure a safer and more sustainable future for all.


How are extreme weather events linked to climate change?

Extreme weather events, such as heatwaves, floods, and wildfires, are becoming more frequent and intense due to climate change. Rising global temperatures disrupt weather patterns, leading to more severe and prolonged periods of extreme weather.

Are these extreme events happening only in the United States?

No, extreme weather events are occurring worldwide. The impacts of climate change are felt globally, with record-breaking events observed in various regions, including Europe, Asia, and North America.

What is the significance of attribution studies?

Attribution studies help scientists determine the likelihood of a specific weather event occurring in a cooler climate. They provide valuable insights into the influence of climate change on extreme weather, highlighting the urgent need to address its underlying causes.

How can individuals contribute to addressing climate change?

Individuals can contribute to addressing climate change by reducing their carbon footprint through actions such as conserving energy, using public transportation, and supporting renewable energy sources. Additionally, advocating for sustainable practices and policies can drive broader change.

What is the role of international cooperation in tackling climate change?

International cooperation is crucial in tackling climate change. By sharing knowledge, resources, and best practices, countries can work together to develop effective strategies, reduce emissions, and adapt to the changing climate. Collaboration at a global scale is necessary to address this pressing challenge.
