The 2023 summer recorded the hottest in over two millennia, according to recent research. The unprecedented heat wave caused wildfires in the Mediterranean, buckled roads in Texas, and strained power grids in China.

This conclusion comes from one of two studies released on May 14th. It highlights the escalating global temperatures and increasing climate-warming emissions.

2023 Summer recorded the hottest

Scientists had already declared the June to August period of last year as the warmest since record-keeping began in the 1940s. However, a study published in the journal Nature now suggests that the 2023 heatwave eclipsed temperatures spanning a far longer timeline.

This finding was established by analyzing meteorological records dating back to the mid-1800s. It was done after examining tree rings from nine northern sites.

When you look at the long sweep of history, you can see just how dramatic recent global warming is,” said Jan Esper. He’s a climate scientist at Johannes Gutenberg University in Germany and a co-author of the study.

The study highlighted that the summer season temperatures on lands between 30 and 90 degrees north latitude were 2.07 degrees Celsius (3.73 degrees Fahrenheit) higher than pre-industrial averages.

Based on tree ring data, the summer months in 2023 were, on average, 2.2 degrees Celsius (4 degrees Fahrenheit) warmer than the estimated average temperature from the years 1 to 1890.

This finding, while stark, was not entirely unexpected. In January, scientists from the European Union’s Copernicus Climate Change Service had predicted that 2023 was “very likely” to be the warmest year in some 100,000 years.

However, proving such a long record is challenging. Esper and two other European scientists argued that year-by-year comparisons over such vast time scales are not feasible with current scientific methods. Those methods include analyzing marine sediments and peat bogs.

The extreme heat of 2023 was exacerbated by the El Nino climate pattern. It’s known for causing warmer global temperatures and leading to longer and more severe heat waves and extended periods of drought.

This intense heat is already taking a toll on people’s health. According to a second study published on Tuesday in the journal PLOS Medicine, more than 150,000 deaths in 43 countries each year between 1990 and 2019 were linked to heat waves.

This accounts for about 1% of global deaths, a figure comparable to the impact of the COVID-19 pandemic. More than half of these heatwave-related deaths occurred in populous Asia.

When adjusted for population size, Europe had the highest per capita toll, with an average of 655 heat-related deaths per year per 10 million residents. Within Europe, Greece, Malta, and Italy registered the highest excess deaths.

As the 2023 summer recorded the hottest, it’s a concerning situation. Extreme heat can cause significant health issues, including heart problems, breathing difficulties, and heat stroke. As global temperatures continue to rise, the frequency and severity of such health impacts are expected to increase. This underscores the urgent need for climate action and adaptation strategies.
