The Final Impact of Heatwaves Across the World

Have you heard the news? Climate change is impacting the way our world works. Whether you believe it is a human-made condition or a natural planetary cycle doesn’t matter at this point. 


We know the world is getting warmer. That means the impact of heatwaves globally can cause massive changes to how all of us approach life.

Record-Breaking Heat Struck the Pacific Northwest in June

When the first heat dome formed in 2021, it sent temperatures through the roof in places where air conditioning isn’t installed in homes by default. Portland and Seattle both reached more than 108 °F, with the former topping out at 116°F.

In July, another heat dome formed in Northern California, causing temperatures around Sacramento to soar above 120°F in localized spots.

Canada recorded its highest temperature ever in Lytton at 49.6°C, shattering the 45°C reading from 1957. It’s the highest temperature recorded above 50N latitude. 

Long-Term Drought Amplifies the Problem

If you take a trip to Lake Shasta or Lake Mead, you can see how much the water levels have shrunk in recent years. With the dry conditions amplifying the heat, water is becoming a scarce commodity.

Most heat waves last for about five days, although they can linger if high-pressure systems get blocked. 

It’s not just during the day that we need to worry about things. The overnight low temps since 1895 have been increasing at nearly twice the rate of afternoon highs, and the ten warmest minimum temperatures in the United States ever recorded have all happened since 2002.

What can we do to make changes? It starts by switching from the burning of fossil fuels. By reducing the amount of greenhouse gases in the atmosphere that reflects heat and sunlight, we can dissipate the heat more readily. 

We’re running out of time to act. Things will keep getting worse until changes are made. It will take all of us to battle this problem together.
