US EditionScientists detect a sudden acceleration in global warming
- A newly published paper in Geophysical Research Letters shows a clear acceleration in global warming since around 2015, with Potsdam Institute for Climate Impact Research researchers reporting over 98% statistical certainty, co-author Grant Foster said.
- Using noise-reduction across five datasets, the team filtered nonhuman influences in NASA, NOAA, HadCRUT, Berkeley Earth, and ERA5, applying quadratic trend analysis and a piecewise linear model to detect warming shifts since the 1970s.
- The study found about 0.35°C per decade in the past 10 years, compared with about 0.2°C per decade earlier, and adjusted results show over 98% confidence in this acceleration.
- Escalating extreme weather — heat, floods, snow and fires — reflects shifting climate patterns that produce unprecedented extremes affecting communities and ecosystems.
- While not attributing a single cause, the study indicated that greenhouse gas emissions are a likely explanation, warning that zero CO2 is needed to prevent exceeding the Paris Agreement 1.5 limit.

As temperature records have been broken over the past three years, scientists are investigating whether global warming is accelerating, and if so, why. According to a new study, the rate of global warming has accelerated sharply since 2015 and is now almost twice as fast as in the 1970s, according to Nature.
The Earth’s atmosphere warms up at a speed never before recorded. Although the global temperature has been rising for 150 years, the alarms went up shortly after the middle of the last century, when a great acceleration occurred. But this increase was small compared to the one that took place in the last ten years. If just over 40 years ago, the rate at which the temperature climbed was 0.20°C for every decade, from 2015 the interval became 0.35…
New study reveals humans are accelerating global crisis faster than ever before: 'Pretty widespread’
New research determined that the rate at which the planet is heating has increased, the Guardian reported. What's happening? It's not "new news" that average temperatures are climbing. However, a newly published entry in Geophysical Research Letters carried an alarming finding about how that warming is accelerating. Scientists had previously observed an ongoing uptick in "extreme heat," with several of the past few years breaking heat records. …

Global warming has picked up speed in the past decade, according to a new analysis from the Potsdam Institute for Climate Impact Research (PIK). By removing short term natural influences such as El Niño, volcanic eruptions, and solar cycles from temperature records, researchers uncovered a clear acceleration in the planet’s long term warming trend beginning around 2015.
