The United Nations climate agency on Wednesday published a first draft of the political decision countries will issue at the end of the COP26 summit.

Negotiators from nearly 200 countries will work from the draft to strike a final deal before the summit ends on Friday.

The "COP cover decision" is being closely watched for what it might commit countries to do to bridge the gap between their current climate targets and the more ambitious action scientists say is needed to avert disastrous levels of warming.
