According to NOAA, heat waves were nevertheless exacerbated by global warming. Of course, any amplification in heat waves is counterbalanced by extreme cold events becoming 30 times less likely. Importantly, global warming’s reduction of extreme cold events provides more human health and welfare benefits than any harm caused by an increase in heat waves. Official government mortality statistics show people are much more likely to die during winter months and extreme cold events than during summer months and heat waves.
