Last summer was identified as the hottest in at least 2,000 years based on new research.
Scientists used tree ring data to compare last year's extreme heat with temperatures over the past two millennia.
The average temperature from June through August was 2.2 degrees Celsius warmer than the average summer temperature between 1 and 1890 in the Northern Hemisphere.
The Paris Agreement aims to keep global warming below 2.7 degrees Fahrenheit (1.5 degrees Celsius), but the Northern Hemisphere has already breached this threshold.
Last summer, marked by deadly extreme heat and devastating wildfires, was identified as the hottest in at least 2,000 years based on new research. The findings offer a stark insight into the unparalleled warming the world is experiencing today due to human-induced greenhouse gas emissions from burning fossil fuels. According to studies published in Nature, last summer's average temperature from June through August was 2.2 degrees Celsius warmer than the average summer temperature between 1 and 1890 in the Northern Hemisphere.
Scientists used tree ring data to compare last year's extreme heat with temperatures over the past two millennia, revealing that it surpassed all previous records. The researchers attributed most of the recent increases in Earth's temperature to human-caused climate change and other factors such as El Niño, undersea volcanic eruptions, and a reduction in sulfur dioxide aerosol pollution from container ships.
The Paris Agreement aims to keep global warming below 2.7 degrees Fahrenheit (1.5 degrees Celsius), but the Northern Hemisphere has already breached this threshold according to the study.
Jan Esper, a climatologist at Johannes Gutenberg University in Mainz, Germany and lead author of one of the studies, emphasized that recent global warming is dramatically evident when looking at long-term history. The extreme heat during summer 2023 was described as unparalleled across much of the Northern Hemisphere.
The summer of 2023 was the hottest in the Northern Hemisphere in the last 2,000 years, according to a new study published in the journal Nature.
The average temperature from June through August 2023 was 2.2 degrees Celsius warmer than the average summer temperature between 1 and 1890.
Scientists attribute most of the recent increases in Earth’s temperature to extra greenhouse gases in the atmosphere from burning fossil fuels, but other factors such as El Niño, an undersea volcanic eruption, and a reduction in sulfur dioxide aerosol pollution from container ships may have contributed to the extremity of the heat last year.
Accuracy
The summer of 2023 was the hottest in the Northern Hemisphere in the last 2,000 years.
Last summer was at least 0.5 degrees Celsius warmer than any other summer over the past 2,000 years.
Last summer was the warmest in at least 2,000 years according to new research.
Using tree ring data, scientists found the summer of 2023 was warmer than any other summer between the years 1 and 1849.
The study calculated that the summer of 2023 was 2.2 degrees Celsius hotter than the long-term pre-industrial average.
A report published in November found humanity lived through the hottest 12-month period in at least 125,000 years.

The author uses an appeal to authority fallacy when stating that the findings offer a 'stark insight into the unparalleled warming the world is experiencing today' and that 'some scientists warn 2024 is on track to be even hotter still.' While it is true that scientists have made these claims, it does not mean they are automatically correct. The author also uses an inflammatory rhetoric fallacy when describing last summer as 'deadly extreme' and the warming as 'unparalleled.' Additionally, the author makes a hasty generalization when stating that 'Global warming is currently tracked by comparing temperatures to the pre-industrial era,' implying that this is the only way to measure global warming.
]The findings offer a stark insight into the unparalleled warming the world is experiencing today[
Some scientists warn 2024 is on track to be even hotter still.
The summer of 2023 was the hottest in 2,000 years in the Northern Hemisphere.
The difference between last summer’s temperatures and those of a cold period in 536 CE was 3.93 degrees Celsius.
Pre-industrial temperatures were cooler than previously thought, making the temperature rise even greater.
Accuracy
Last summer was at least 0.5 degrees Celsius warmer than the warmest summer identified in this study, which occurred in the year 246.
Summer 2023 was nearly 4 degrees Celsius warmer than the coldest summer identified, which occurred in the year 536.

The author makes an appeal to authority by quoting scientists and the U.N. head stating that last summer was the hottest in 2,000 years in some parts of the world. However, they do not explicitly state that this is a fallacy or provide any counterevidence.
Parts of U.S. scorched by September heat wave
U.N. head says climate breakdown has begun as scorching September heat hits U.S.
In what they call an ‘alarming finding,’ scientists say that in the Northern Hemisphere, the summer of 2023 was the hottest in 2,000 years.
Summer 2023 was the hottest in the past 2,000 years based on tree ring analysis in a new study.
Study authors described the warmth during summer 2023 as ‘unparalleled’ across much of the Northern Hemisphere.
Jan Esper, lead author from Johannes Gutenberg University, stated that recent global warming is dramatically evident when looking at long-term history.
The Paris Agreement to keep warming below 2.7 degrees Fahrenheit (1.5 degrees Celsius) has already been breached in the Northern Hemisphere according to the study.

The article contains an appeal to authority fallacy when the authors of the study are described as describing the summer of 2023 as 'unparalleled' and Jan Esper is quoted saying 'It's true that the climate is always changing, but when you look at the long sweep of history, you can see just how dramatic recent global warming is.' This implies that because these experts have made such a statement, it must be true. However, an appeal to authority does not make an argument or claim logically valid on its own. Additionally, there is a use of inflammatory rhetoric when the summer of 2023 is described as 'the hottest in the past 2,000 years' and 'exceptional warmth.' This language creates an emotional response rather than a logical one.
The authors described the warmth during the summer of 2023 across much of the Northern Hemisphere as ‘unparalleled.’
It’s true that the climate is always changing, but when you look at the long sweep of history, you can see just how dramatic recent global warming is.
Last summer was 4 degrees warmer than the estimated average temperatures for the years 1 to 1890, based on these tree ring proxies.
The authors are analyzing midlatitude summer temperatures in the Northern Hemisphere (which are warming much faster than the annual global ocean plus land average), so it’s a thoroughly improper measure of how close we are to the actual thresholds of 1.5C and 2C that have been defined in terms of global annual warming.
