Is More Late-Summer Heat to Come? | Climate Friday

Back-to-back Heat Waves Scorch Northern Hemisphere

With the Northern Hemisphere officially into astronomical autumn, many are wondering if the brutal heat waves that have scorched the globe all summer will finally give way to fall's cooler temperatures. Unfortunately, the answer seems to be no, and more late-summer heat is likely on the way.

Climate Change and Extreme Heat

Experts say that climate change is the primary driver of these extreme heat events. As the planet warms, the atmosphere can hold more moisture, leading to more frequent and intense heat waves. Additionally, human activities such as deforestation and urbanization contribute to the formation of heat islands, exacerbating the effects of heat waves in cities.

Is There Any Relief in Sight?

While it's impossible to say for certain when the heat waves will end, there are some signs that relief may be on the horizon. In the United States, a shift in the jet stream is expected to bring cooler temperatures to the eastern half of the country by the end of the week. However, the western half of the country is likely to remain under a heat dome for at least another week.

What to Do During a Heat Wave

If you're experiencing a heat wave, it's important to take precautions to stay cool and hydrated. Here are some tips:

• Stay indoors as much as possible. If you must go outside, wear loose-fitting, light-colored clothing and sunscreen.
• Drink plenty of fluids, even if you don't feel thirsty.
• Avoid strenuous activity during the hottest hours of the day.
• Take cool showers or baths to cool down.
• Check on elderly or vulnerable neighbors and family members.

Conclusion

While the heat waves of summer 2023 have been brutal, there is hope that relief is on the way. However, it's important to remember that climate change is making extreme heat events more frequent and intense. We must all do our part to reduce our greenhouse gas emissions and mitigate the effects of climate change.
