15. What assessment he has made of British Antarctic Survey research on the effects of historic industrialisation on global carbon dioxide levels.

Ice core measurements by the British Antarctic Survey reveal that over the last 800,000 years, global carbon dioxide levels varied between 180 and 300 parts per million. Those peer-reviewed results provide crucial data on past natural levels for climate science research. Observations show that global atmospheric carbon dioxide levels are currently increasing at about two parts per million per year, and are now at 391 parts per million, as a result of emissions from industrial and other human sources.

I can certainly point to one conclusion of the research that I think is absolutely crucial: measurements of current carbon dioxide levels show that they have increased by nearly 40% since pre-industrial times, and carbon isotope information shows that this has largely been caused by the burning of fossil fuels. Drilling down into ice cores is a fascinating way of finding out what was happening in prehistory, and it thoroughly underlines the importance in the science of our addressing those issues. One thing that as politicians we cannot do is negotiate with scientific conclusions as robustly supported as these.
