Scientists express worsening concerns over climate change, as global temperatures exceeded 1.5C above pre-industrial levels for 21 of the last 22 months, with the average for the past year at 1.58C above. The COP29 climate summit in Copenhagen highlighted a warning from UN climate chief Simon Stiell that the world is on a path to a 3C rise, urging immediate action to mitigate emissions, particularly methane. Despite the Paris accord’s goal to limit increases to 1.5C, current trends suggest rapid climate extremes and a need for significant greenhouse gas reductions across all sectors.
