Economic damages from carbon emissions could be up to four times higher than previously estimated, while global sea level rise is already locked in for centuries, according to a new report. The report, 10 New Insights in Climate Science 2026/2027 by Future Earth, The Earth League and the World Climate Research Programme (WCRP), also finds that 2025 was about 1.43°C warmer than the pre-industrial baseline, while human activities released a record 38.1 billion tonnes of CO2 from fossil fuels and cement production. The report draws on scientific evidence published between January 2025 and June 2026 and identifies 10 developments spanning physical climate change, water security, food systems, carbon economics, climate accountability, trade and geopolitics. It noted that the 2015 to 2025 period constituted the 11 warmest years on record, according to the World Meteorological Organization (WMO). Global atmospheric CO2 concentration reached approximately 425.6 parts per million (ppm) in 2025, 53 per cent above its pre-industrial level. The latest nationally determined contributions imply only a 12 per cent reduction in global emissions by 2035 from 2019 levels, compared with the approximately 55 per cent required for a pathway consistent with limiting warming to 1.5°C. “The evidence is unequivocal: 1.5°C is a...
