Doomsday Schedule in Tree Trunks
Jakarta, CNBC Indonesia – Researchers have found evidence that the ‘doomsday’ of global warming is getting worse. Summer 2023 has proven to be the hottest period in the last 2,000 years or since the birth of Jesus Christ.
To measure Earth’s temperature, humans currently rely on satellite data. However, temperature data taken from satellites has only been recorded for the past 50 years. Likewise, temperature records in certain areas. The oldest annual temperature record was in 1850.
Ulf Buntgen from the University of Cambridge and his team used a different approach to determine Earth’s temperature. The results of their analysis of tree rings, the ring-like lines visible from tree trunk sections, show that the 2023 period will be the hottest period in at least the last 2,000 years.
The size of the tree ring, according to IFLScience, describes the environmental conditions experienced by the tree in a particular year. In areas that have abundant water sources, temperature differences between one year and another are more visible. Buntgen relies on large amounts of data to build each year’s weather record.
“Looking very long at history, you can see how extraordinary global warming is in the current period. 2023 is a very hot year, this trend will continue if greenhouse gases are not reduced massively,” said Buntgen.
The results of Buntgen and his team’s analysis show several extreme years in the last 2,000 years. The coldest weather occurred in 536. Summer that year was 3.93 degrees Celsius lower than last year.
Research also finds that the temperature increase at the start of the industrial revolution was much lower than in the current period. Once again showing how serious the conditions are now. Based on Buntgen’s data, the summer of 2023 is 2.07 degrees Celsius hotter than the period 1850-1900.
The new data renders the temperature rise targets set by the 2015 Paris Agreement and measurements of the severity of “global warming” based on that agreement also imprecise.
Based on data agreed in Paris, 2023 will be 1.52 degrees Celsius hotter than the period 1850-1900. However, based on Buntgen’s data, the difference between last summer and the period before the industrial revolution was 2.2 degrees Celsius.
“It’s true that the climate is always changing, but warming in 2023, caused by greenhouse gases and exacerbated by El Nino, is causing heat waves and longer periods of drought. This shows it is very important to immediately reduce greenhouse gas emissions,” said Jan Esper of Johannes Gutenberg University Mainz.
Buntgen’s research illustrates that the summer of 2023 is the hottest season since the era of Jesus Christ and the timetable for a “climate change apocalypse” is much shorter than previously believed.
