World warming at an accelerated rate, scientists report

Scientific agencies report that global warming has accelerated since the mid‑2010s, with 2025 among the three hottest years on record and greenhouse gases at record levels.

New climate datasets show the world is warming at an accelerating pace a decade after the Paris Agreement took effect. Scientists reported that 2025 ranked among the three hottest years on record and noted rising ocean heat and sea levels. Agencies including the World Meteorological Organization said concentrations of carbon dioxide, methane and nitrous oxide have reached record highs. The newsletter also highlights differing policy paths, with some governments expanding clean energy while others have rolled back environmental rules. Key findings: - Scientific agencies report accelerated global warming since the mid‑2010s, with 2025 among the three hottest years on record. - The WMO's Global Atmosphere Watch and related datasets show record concentrations of carbon dioxide, methane and nitrous oxide. - The Global Carbon Budget projected global fossil-fuel CO2 emissions at about 38.1 billion metric tons in 2025. - Reporting notes substantial growth in renewables in some regions, including wind and solar producing more electricity than fossil fuels in the EU last year and China drawing roughly half of its energy from clean sources, according to cited data. Summary: The reporting indicates faster warming alongside rising greenhouse gas concentrations and higher global emissions, even as some regions expand clean energy and others change regulations. Undetermined at this time.
