Ars Technica reported on November 13, 2026, that scientists warn the 1.5C global warming threshold could arrive by 2029. The report said climate action has stalled for five years while fossil fuel development keeps growing. Copernicus, the European Union's climate change service, said global warming has accelerated since the 2015 Paris agreement and is now projected to cross the pact's 2.7 degrees Fahrenheit threshold as soon as 2029, rather than around 2045 as first projected. Climate Action Tracker found the planet still on track to warm nearly 5 degrees Fahrenheit by 2100. Climate Analytics' Sarah Heck said collective government action has stalled for a fifth consecutive year, and even the most optimistic scenario would bring about 3.4 degrees Fahrenheit of warming by 2100. The reports were released at the COP31 climate conference in Antalya, Turkey, where Greta Thunberg said the current warming has already caused deadly floods, wildfires and glacier collapses. Niklas Höhne of The New Climate Institute said renewables progress has not yet bent the curve fast enough, and he criticized co-hosts Turkey and Australia for opposing the word "clean" in electrification targets. Turkey and Australia have not offered specific plans to transition away from fossil fuels, according to the article. Bill Hare of Climate Analytics criticized wealthy countries for lacking climate leadership, noting that European Commission President Ursula von der Leyen did not mention transitioning away from fossil fuels in her COP31 speech.
