"As emissions continue to rise albeit more slowly the authors said the world was on track to overshoot the 1.5 C threshold, "at least temporarily." Signatories to the 2015 Paris climate accord agreed to try and limit temperatures from rising more than 2 degrees above pre-industrialization levels, with efforts to cap the increase at 1.5 C. Even if countries were to do everything to reach their self-set national climate targets, the world would still be heading for warming of between 2.3 and 2.5 degrees Celsius by the end of the century."
"This is a slight improvement on last year's predictions, but under current policies, the study says, the world is actually on track for 2.8 degrees of warming by 2100. That temperature rise would be "difficult to reverse" and would require much faster additional reductions in the greenhouse gas emissions generated by burning oil, gas and coal."
""while national climate plans have delivered some progress, it is nowhere near fast enough," adding that proven solutions already exist. "From the rapid growth in cheap renewable energy to tackling methane emissions, we know what needs to be done," she said. "We still need emissions cuts in an increasingly tight window, with an increasingly challenging geopolitical backdrop.""
Global temperatures in 2024 reached record highs, marking the hottest year ever recorded. Predicted global temperature increase this century has decreased only slightly, leaving the world headed for serious escalation of climate risks. Emissions continue to rise, albeit more slowly, keeping the world on track to overshoot the 1.5°C threshold at least temporarily. Even with full implementation of current national targets, projected end-of-century warming falls between 2.3°C and 2.5°C. Under existing policies, warming could reach about 2.8°C by 2100. Reversing such temperature rise would be difficult and requires much faster reductions in greenhouse gas emissions from fossil fuels. Rapid expansion of cheap renewable energy and methane cuts are identified as proven mitigation options.
