President Xi Jinping's special representative at the United Nations climate summit has called for a strengthening of early warning systems and enhancing climate adaptation capacity.

Vice Premier Ding Xuexiang was addressing a high-level meeting held by China on Tuesday, during COP29 in Baku, Azerbaijan.

Ding, who's also a Politburo Standing Committee member, said China attached great importance to international cooperation on meteorological early warnings and that President Xi had made specific requirements on this issue.

During the meeting, Ding proposed three points, including standardising climate risk assessments, building a global early warning network by sharing technology and enhancing interconnectivity, and establishing a climate adaptation partnership.

He said China would develop a South-South cooperation flagship project for early warning in response to climate change, and support developing countries with meteorological observation equipment, early warning systems, and training.

Elsewhere at the summit, scientists said global carbon dioxide emissions, including those from burning fossil fuels, would hit a record high this year, pulling the world further off course from averting more destructive climate extremes.

The Global Carbon Budget report, published during the climate summit, said global CO2 emissions are set to total 41.6 billion metric tons in 2024, up from 40.6 billion tons last year.

The report forecast that emissions in China would marginally increase by 0.2 percent.

The report's authors said China's emissions from oil use have likely peaked, as electric vehicles gain market share. (Agencies)
