Hell on earth: weather anomaly confirming climate shift

Extreme weather events are one of the most tangible effects of climate change. Events such as the heatwave affecting northern India these days, where around 100 people died due to a mix of temperatures above 40 degrees and rapidly increasing humidity, which can be fatal to the most fragile strata of the population. Such conditions are hardly the norm, but are becoming more likely and therefore common due to global warming. Another example is Mexico and Texas, where a heat balloon positioned close to the south of the United States caused temperatures in excess of 40 degrees Fahrenheit (the perceived heat index used by American officials to give warnings). 50 is a value considered dangerous for human health.

Especially in Texas, the heat has broken several records in recent days. From the capital, where it hits 41 degrees, to San Antonio, the hottest-ever temperature of over 40 degrees, through smaller centers like Cotulla County, where thermometers hit 46 degrees, or through the Falcon Lake reserve in the south. The country where 47 degrees is reached.

Such an intense heatwave has hardly been recorded in the US state, where even high temperatures are certainly not uncommon. It’s impossible to say what the cause of such a meteorological event is, but almost all experts agree that such extreme events are more likely due to ongoing climate change. For example, meteorologist Jeff Berardelli recalls in a tweet that these days’ temperatures are a statistical anomaly in the country compared to the historical series recorded in June, such an existence would be practically impossible if the climate had changed. climate change due to human activities.

Even data processed by the American nonprofit Climate Center point in the same direction, given that it assigned a value of 5 (maximum) on the Climate Change Index, a parameter designed to assess how much heat can be attributed to global warming. to those recorded in Texas these days.

If the south of the American state is devastated by an anomalous heatwave, the consequences will be felt in the North as well: temperatures and humidity are actually fueling powerful storms and hurricanes that hit areas of the US directly north of the heat bubble. : Last week, a hurricane killed 3 people in the northern Texas city of Perryton, while damage from strong winds severely damaged energy infrastructure in the east of the country, leaving at least 40,000 without power. There is also fear across the state of Texas that the power grid will suffer due to heavy air conditioning use caused by these days’ very high temperatures, so much so that the network administrator had to ask for voluntary assistance from all citizens. rationing of electricity in hopes of preventing blackouts.

Conditions will remain stable throughout the weekend, with very high temperatures in the southeastern US and Mexico. However, this is not the first extreme heat wave of 2023. At the beginning of June, temperatures exceeding 40 degrees were recorded for days in Puerto Rico, and the heat index was above 51. It started multiple fires that covered New York with smoke and made the air in the Big Apple unbreathable for days. And as we remember at the beginning of the article, an abnormal heat wave that has also hit some states of northern India in the last days has already caused close to a hundred deaths due to very high temperatures and humidity.
