Global warming accelerated significantly since 2015: Study

NEw new delhi, world-wide warming has accelerated significantly since 2015, according to a consider that accounts for cancel fluctuations in warming value and influences of El Nino events, volcanic eruptions and solar cycle variation on temperature data.Researchers, including those from Germany's Potsdam Institute for Climate Impact Research, said short-term natural fluctuations in global temperature caused by El Nino, volcanic eruptions, and solar cycles can mask changes in the long-term rate of warming.The study published in the journal Geophysical Research Letters analysed five global temperature datasets, including those managed by NASA and the National Oceanic and Atmospheric Administration ."We filter out known natural influences in the observational data, so that the 'noise' is reduced, making the underlying long-term warming signal more clearly visible," co-author Grant Foster, a US statistics expert, said."The resulting adjusted and thus less "noisy" data show that there has been acceleration with over 98 per cent confidence, with faster warming in last 10 years than during any previous decade," the authors wrote.Statistical confidence is the chance that a specific statistical method will correctly capture the true population value upon repeated sampling.Subtracting the estimated influence of El Nino events, volcanic eruptions and solar variations from the datasets makes the global temperature curve less variable, which "then shows a statistically significant acceleration of global warming since about the year 2015," the team said.They also found that the years 2023 and 2024, which were exceptionally warm, become somewhat cooler, but remain the two warmest years since the beginning of instrumental records.They added that while an accelerated warming is not unexpected, it is a cause of concern and shows that efforts directed at slowing and eventually stopping global warming under the Paris Agreement have so far been insufficient."If the warming rate of the past 10 years continues, it would lead to a long-term exceedance of the 1.5 degrees Celsius limit of the Paris Agreement before 2030," lead author Stefan Rahmstorf, a researcher at the Potsdam Institute for Climate Impact Research, said."How quickly the Earth continues to warm ultimately depends on how rapidly we reduce global emissions from fossil fuels to zero," Rahmstorf said.This article was generated from an automated news agency feed without modifications to text.
