Could this be a result of climate change? June 2021 was the hottest June on record for 48 states.
The average June temperature in the United States was 72.6 degrees, 4.2 degrees higher than the average monthly temperature. This record-breaking warmth allowed June 2021 to surpass the record set in June 2016 by 0.9 degrees Fahrenheit. Much of the heatwaves occurred in the western side of the United States. These most commonly occur when high atmospheric pressure moves into one area, one of the major effects of global warming.
2021 brought 8 climate disasters in the first six months of 2021. 4 severe storms, 2 floods, 1 winter storm, and 1 drought. These disasters each caused damages that exceeded 1 billion USD. For example, the infamous winter storm that froze Texas and its power sector caused over 20 billion dollars of damage. The last time that a winter storm did this much damage was in 1993, where hundreds of people died in the snowstorm and supermarkets were all out of stock. People were left to resist for themselves, lacking heat, and some had to resort to sleeping inside cars due to the frigid weather.
It is obvious that the natural disasters that are occurring in 2021 are a result of pollution and human activity, which is likely to have been the cause of the heatwave earlier this month.
As a direct consequence of climate change, sudden changes in the weather and climate are inevitable and will increase their threat on humanity under the scenario where we leave greenhouse gas emissions as well as environmental damage unchecked.
Heatwaves themselves will likely increase in frequency and will bring higher, deadly temperatures to our lives. This is an extremely important implication of climate change for the economy: Increases in temperature will likely bring about extensive losses in people's working capacity, together with a significant increase in deaths caused by heat strokes. These effects make part of the social cost of greenhouse gas emissions, arising from the negative externality created by fossil fuel-intensive activities. Therefore, as the rate of global warming increases, the costs arising from the negative externality are magnified, which detracts from the world's social welfare, making humanity as a whole worse off.
