A new study is claiming that as many as three out of every four days of extremely hot weather can be attributed to mankind’s effects on the environment.

And the news gets worse — the percentage of very hot days caused by us pumping greenhouse gases into the atmosphere will increase to 95 percent around the midcentury mark, states the study, which was published in the journal Nature Climate Change this week by scientists in Switzerland.

The scientists calculate that there is an 18 percent chance that any extreme rain event is caused by global warming, a much lower percentage than the hot days, but if the world keeps getting warmer and crosses the 2 degrees Fahrenheit threshold, that figure could grow to 39 percent.

The study could help scientists better understand human influence on the environment and what it practically means in terms of the weather we experience every day. It might help spell out in practical terms to average citizens the importance of taking action to reduce emissions of carbon dioxide from burning oil, gas, and coal.

To make the findings, the researchers looked at the very hottest days, and used 25 computer models to simulate what the world would look like without the heavy greenhouse gas emissions. They determined that such extremely hot days would happen only once in a three-year time period.

When the greenhouse gases are taken into account, the number of extremely hot days in three years is four days, meaning that the extra three days are from manmade effects.

It gets worse: when the scientists increase greenhouse gases based on the current expected pollution rates to where it would be midcentury, that figure increased to a stunning 26 very hot days.

Some areas of the world are more heavily impacted than others. Africa and South America saw percentages of about 89 and 88 percent based on the computer models, whereas Europe was at 63 percent and North America at 67 percent.
