A note about temperatures

WUWT
" I don’t believe that carbon dioxide is a major greenhouse gas and our use of fossil fuels is creating a climate crisis now and it will not do so in the future as well. I don’t see any evidence that there is a CO2 “tipping point” when temperatures will go out of the control. In fact, there is evidence that CO2 has been much higher in the historic past. I also point out that CO2 is fertilizing our crops producing a food supply significantly greater than it would be if we were not adding carbon dioxide to the atmosphere. I conclude the temperature data does not prove global warming. The alarmists are wrong. But the temperature data is so unreliable and garbled that neither alarmists or skeptics can use it to conclusively prove they are right."
