![]() Real-time data from specific locations show that levels of the three greenhouse gases continued to increase in 2023. Observed concentrations of the three main greenhouse gases – carbon dioxide, methane, and nitrous oxide – reached record high levels in 2022, the latest year for which consolidated global values are available. The final State of the Global Climate 2023 report, along with regional reports, will be published in the first half of 2024. The temperature figures are a consolidation of six leading international datasets. It combines input from National Meteorological and Hydrological Services, regional climate centres, UN partners and leading climate scientists. The WMO provisional State of the Global Climate report was published to inform negotiations at COP28 in Dubai. Renewable energy capacity grew nearly 10% in 2022, led by solar and wind power. But we need leaders to fire the starting gun at COP28 on a race to keep the 1.5 degree limit alive: By setting clear expectations for the next round of climate action plans and committing to the partnerships and finance to make them possible By committing to triple renewables and double energy efficiency And committing to phase out fossil fuels, with a clear time frame aligned to the 1.5-degree limit,” he said. ![]() “We have the roadmap to limit the rise in global temperature to 1.5 ☌ and avoid the worst of climate chaos. In a video message accompanying WMO’s climate report, Mr Guterres urges leaders to commit to urgent action at the UN Climate Change negotiations, COP28. Record global heat should send shivers down the spines of world leaders,” said United Nations Secretary-General António Guterres. “This year we have seen communities around the world pounded by fires, floods and searing temperatures. ![]() It provides a snapshot of socio-economic impacts, including on food security and population displacement. The report shows the global reach of climate change. Swiss glaciers have lost about 10 percent of their remaining volume in the past two years, according to the WMO report. Glaciers in North America and Europe once again suffered an extreme melt season. The maximum Antarctic sea-ice extent for the year was the lowest on record, a full 1 million km2 (more than the size of France and Germany combined) less than the previous record low, at the end of southern hemisphere winter. The rate of sea level rise from 2013-2022 is more than twice the rate of the first decade of the satellite record (1993-2002) because of continued ocean warming and melting of glaciers and ice sheets. The long lifetime of CO2 means that temperatures will continue to rise for many years to come. Taalas.Ĭarbon dioxide levels are 50 % higher than the pre-industrial era, trapping heat in the atmosphere. “Extreme weather is destroying lives and livelihoods on a daily basis – underlining the imperative need to ensure that everyone is protected by early warning services,” said Prof. ![]() We cannot return to the climate of the 20th century, but we must act now to limit the risks of an increasingly inhospitable climate in this and the coming centuries,” he said. We risk losing the race to save our glaciers and to rein in sea level rise. It’s a deafening cacophony of broken records,” said WMO Secretary-General Prof.
