The author, Robert M Carter argues against Anthropogenic Global Warning and his book is called Climate: the counter consensus. In it he makes two related claims: that the cumulative funding on climate research bureaucracy and advocacy by western governments exceeds $100 billion and the current rate of spending is in excess of $10 billion per year. In his words (I'd quote the page but I can't fathom how to extract it from my Mac Kindle app):
...global warming alarmism is fuelled by an estimated worldwide expenditure on related research and greenhouse bureaucracy of more than US$10 billion annually.
...an estimated expenditure since 1990 of around $100 billion ($79 billion in the USA alone)...
Have western governments spent $100bn on climate change and are they spending $10bn a year?
