Last year was warmer than ever in the Northern Hemisphere

The summer of 2023 was exceptionally hot, and according to a new study, it will get even hotter.

For more than two thousand years, the average summer temperature in the northern hemisphere of our Earth has not been as high as it was in 2023 – this is what a recent study claims, the authors of which write that since the zero year of our time calculation, the period was between June and August of last year. She is the hottest. Scientists from the University of Cambridge and the University of Mainz examined the annual rings of 10,000 trees in order to infer temperature values ​​from centuries or even millennia ago.

They found that in the indicated period the weather was 2.2 degrees Celsius warmer on average than in the years between 1 and 1890 according to the time calculation. According to researchers, this very well shows the extent of global warming today. They say it will get worse if we don't significantly reduce greenhouse gas emissions.

The trees examined came from fifteen different regions of the Northern Hemisphere in order to get the most complete picture possible. Their observations also extended to the Southern Hemisphere, but they did not have enough data from there to reach a similarly well-founded conclusion. The study published in Nature is not the first recently to call for immediate action, as the United Nations World Meteorological Organization and the European Union's Copernicus Program recently reported that the rate of temperature rise in Europe is faster than the global average.
