Morning mail: Obama urges stronger climate action, Morrison approval drops, environmental photos

Tuesday: Barack Obama singles out China and Russia for failing to cut emissions quickly enough. Plus: environmental photographer of the year

Good morning. Poorer countries are demanding richer nations do more to cut emissions. Voter approval of the prime minister is at its lowest since before the pandemic began. And bushfire survivors fear they have been abandoned.

Barack Obama has called on world leaders at Cop26 to step up and step up now" to avert climate breakdown, singling out China and Russia for being foremost among countries that are failing to cut planet-heating emissions quickly enough, and saying most nations have failed to be as ambitious as they need to be". Chinese officials say they are sceptical of claims that Cop26 commitments will keep global heating below 2C, and want other countries to focus on concrete actions rather than distant targets in the final week of the talks. Meanwhile, poor countries say that nations that have failed to come up with national plans on cutting greenhouse gas emissions in line with limiting temperature rises to 1.5C must be forced back to the negotiating table every year from now on.
