International climate pledges remain far off track to limit temperature rises to 1.5 degrees Celsius, according to a UN report released on Wednesday, less than two weeks ahead of high-stakes negotiations to tackle global warming.

With the planet already battered by climate-enhanced heatwaves, storms and floods after just 1.2 degrees Celsius of warming, experts say the world is still failing to act with sufficient urgency.

When nations met in Glasgow last year for a previous round of climate negotiations, they agreed to speed up their climate pledges to cut carbon pollution this decade and increase financial flows to developing nations. But only 24 countries, of 193, had updated their plans at the time of the report.
