Many of the experts (like Dr Hansen) dealing with
global warming rightfully only look at what they think is going on and since the concentration of carbon dioxide (although I still have no idea how they can get an

global warming is this increase of carbon dioxide.
If we multiply that
over ten years, and figure that the top billion or so of world population is responsible for the lion's share (say 80 %) of the emissions, could we then conclude that, on

global warming that was at its strongest
over that period
Certainly, but whether high or low, if the Sun is going to influence

over that period?
The economic constraint on environmental action can easily be seen by looking at what is widely regarded as the most far - reaching establishment attempt to date to deal with The Economics of Climate Change in the form of a massive study issued in 2007 under that title, commissioned by the UK Treasury Office.7 Subtitled the Stern Review after the report's principal author Nicholas Stern, a former chief economist of the World Bank, it is widely viewed as the most important, and most progressive mainstream treatment of the economics of
global warming.8 The Stern Review focuses on the target level of carbon dioxide equivalent (CO2e) concentration in the atmosphere necessary to stabilize
global average temperature at no more than 3 °C (5.4 °F)
over pre-industrial levels.

average), and was the
warmest since 1891.
