The year 2023 has been recorded as the hottest year on Earth in its 2,000 years history, researchers said.

The year 2023 has also been found to be the hottest summer in the Northern Hemisphere which is almost four degrees warmer than the coldest summer during the same time.

Scientists from University of Cambridge and Johannes Gutenberg University Mainz by using past climate information from annually resolved tree rings over two millennia have revealed how drastic the summer of 2023.

Exceeding the extremes of natural climate variability by half a degree Celsius, 2023 was still the hottest summer since the height of the Roman Empire even after allowing for natural climate variations over hundreds of years.

"When you look at the long sweep of history, you can see just how dramatic recent global warming is," said co-author Professor Ulf Büntgen, from Cambridge’s Department of Geography.

"2023 was an exceptionally hot year, and this trend will continue unless we reduce greenhouse gas emissions dramatically."

2022 was hottest in Italy, France

The Institute for Atmospheric Science at the country's National Research Council (NRC) had earlier claimed the year 2022 to be the hottest in Italy since records began in 1800.

Likewise, France witnessed 2022 as the second hottest summer since 1900, according to the country's meteorological service.

In the Northern Hemisphere, the 2015 Paris Agreement to limit warming to 1.5C above pre-industrial levels has already been breached, as per the results reported in the journal Nature.
