Earth will overshoot the critical warming threshold of 1.5 degrees Celsius above preindustrial levels within the next decade, the United Nations Environment Programme (UNEP) said Tuesday (Nov. 4).
To stay below this threshold, the world needs to slash annual greenhouse gas emissions by 55%, compared with 2019 levels, by 2035. But given countries' inadequate actions so far, there's little to no chance that will happen, according to the 2025 Emissions Gap report.
