There is a lot that could start a political disagreement, if only due to the "jokes" made at the expense of the people concerned about climate change.
One thing I picked up on which I think anyone who feels that the speaker was speaking truth should investigate, is his citing that the UK is responsible for just 2% of world CO2 emissions. Citing in such a way that it sounds like the UK is a tiny player and can have almost no impact.
Now I don't know what the truth is, I haven't done full research, but I have seen enough to be suspicious whether such low figures include the off-shoring of our manufacturing. If you buy a Kia, or a Samsung, is the CO2 involved in its production attributed to the UK, or Korea? In the past, people wanting to make it sound like the UK was doing more to cut emissions glossed over the fact that shifting manufacturing (and pollution) to Asia wasn't the same as the UK being responsible for fewer emissions. Also, 2% of world total for a country our size and population... Before you can really conclude what that 2% means you need to know how that compares with other countries, both total and per capita.
