Link Between Extreme Weather and Climate Change
A decade ago, scientists could only speculate about the impact of climate change on specific weather events. Now, thanks to advancements in research and technology, we can more accurately pinpoint how climate change influences extreme weather phenomena1. Let’s explore some key points:
Climate Attribution: Connecting the Dots
Precise Attribution: Researchers are now able to calculate climate fingerprints for major weather events. These fingerprints help us understand the extent to which greenhouse gases from fossil fuel burning contribute to specific phenomena. For instance, last summer’s heat wave in the Southwestern United States was five or more times more likely due to climate change1.
Worsening Disasters: Warmer air and ocean surface temperatures exacerbate extreme weather events. Hurricanes, such as Katrina, Irma, and Harvey, have become four to 15 times more intense due to climate change. Similarly, last year’s unusually warm Midwestern Christmas week was at least twice as likely because of climate change1.
Recent Extreme Weather and Climate Change
2022: Extreme weather in 2022 showcased the global impact of climate change. Record-breaking temperatures, droughts, and wildfires highlighted the urgency of addressing climate-related challenges2.
2023: Researchers calculated the impact of human-induced climate change on daily air temperatures in 175 countries and 920 cities from November 2022 to October 2023. The results underscore the need for urgent action3.
Conclusion
Climate change is no longer an abstract concept—it directly affects the intensity and frequency of extreme weather events. As a society, we must transition away from fossil fuels to mitigate these effects and protect our planet.
Remember, we’re not saying climate change caused a specific event; we’re showing how it has modified the severity of these events. Let’s work together to create a sustainable future!
