Copernicus Climate Change Service: 1.5°C could be exceeded as early as 2029, not 2045 as projected in 2015
Copernicus Climate Change Service said at COP31 that average global temperature could exceed 1.5°C above pre-industrial levels as early as 2029, 16 years earlier than estimated in 2015.
At the COP31 climate conference in Antalya, Turkey, the EU's Copernicus Climate Change Service said that the average global temperature could exceed the long-term threshold of 1.5°C above pre-industrial levels as early as 2029, ua.news reports, citing Ars Technica ua.news

The service's scientists noted that this shift indicates a noticeable acceleration of global warming in recent years. Researchers stressed that not all factors behind the recent sharp rise in global temperatures are fully understood. According to them, rising concentrations of greenhouse gases in the atmosphere caused by human activity remain the main driver of the trend.
Other estimates of warming by 2100
A separate analysis by the nonprofit group Climate Action Tracker found that, on the current trajectory, the world is still heading toward warming of nearly 5 degrees Fahrenheit by 2100 compared with pre-industrial levels. Under the most optimistic scenario, which assumes the full implementation of current policies and government pledges, temperatures could rise by 3.4 degrees Fahrenheit by the end of the century.
Fossil fuels and government action
Climate Analytics analyst Sarah Hek said that collective government action on climate has been at a standstill for the fifth consecutive year. According to her, efforts to accelerate the phaseout of fossil fuels are being offset by new oil and gas extraction projects, while some governments are delaying, weakening, or abandoning climate measures ua.news

New Climate Institute researcher Niklas Höhne said that the development of renewable energy has not yet made it possible to change the emissions trajectory quickly enough. He also noted that COP31 co-hosts Turkey and Australia had not presented specific plans for transitioning away from fossil fuels. Australia is one of the world's largest coal exporters, while Turkey's energy sector depends heavily on coal.
