If you haven’t noticed, it’s abnormally hot outside. For several weeks, much of the southern United States has been under a severe heat wave, with record temperatures and heat indexes of 110 degrees or more. Making matters worse is a cranky “heat dome” that refuses to lift.

Along with the increasing temperatures, we’ve seen a wave of discussions about the causes of such brutal heat, with many pointing to climate change as the culprit. Environmental activists are calling on us to reduce our carbon footprint and help protect our planet. And most consumers are familiar with the usual remedies: driving less, recycling, and reducing our use of plastics.
