UK Leads from the Back?

It's somewhat embarrassing that the UK reportedly pushed to host COP26 (the climate change conference scheduled for Glasgow) but now appears to spend more time arguing about who should head the meeting than advocating (and showing?) sensible and timely commitments (https://www.theguardian.com/environment/2020/feb/07/mary-robinson-attacks-unhelpful-uk-over-cop-26-climate-talks). It does not appear that anything other than warm words and distant (well after the current actors have stepped down) undertakings are on offer from politicians.
