UK PM claims there has been a turnaround since G20 summit as he urges China to make improved pledge
Boris Johnson has declared he is “cautiously optimistic” about a deal at Cop26 to keep global temperature rises below 1.5C as he urged China to commit to bringing emissions down by 2025.
The prime minister had previously said the world would be 5-1 down in a football match when it came to the 1.5C target but he said on Monday that the score was now more like 5-2 or 5-3.
