In the meantime, Weather Channel has used a simpler measure, called "feels like, " to express temperature in a temperature-like number, taking into account wind chill at low temperatures and humidity at high temperatures.
Climate sensitivity is how much will the temperature change over a doubling of atmospheric CO2 (more strictly, CO2-e, taking account of methane and all the other gasses and converting them to CO2 equivalents).
His book addresses the argument in cost-benefit terms, and concludes that spending 1-2% of global output to avoid a significant temperature rise is a bargain worth taking a similar conclusion to that in his original 2006 study.
The wind chill today will slice us up - it's taking the temperature down to below -50C, so we have decided to take a day's rest to recharge our batteries and soothe the aches and pains.
