Carbon dioxide wins the environmental battle …

A superb post by Ken Gregory on the economic impact of greenhouse gas emissions, where he points out the science around CO2 sensitivity proves that there is nothing to worry about, except for all the massive trillion dollar waste in trying to alleviate CO2 emissions.

Canada is one country that benefits the most from any warming and increased CO2 emissions,

The FUND model shows that Canada benefits from emissions by 1.9% of gross domestic product by 2100, equivalent to a benefit of $109 Billion annually in 2015 dollars when assuming an ECS of 3 °C. Anthropogenic climate change will have only positive impacts in Canada which increase throughout the 21st century..

but this information about Southern Hemisphere and Tropics data variability is lower, and  shows that Urban Heat Island, or UHIE shows the biggest changes in data over land:

[…] The southern hemisphere and tropics temperature variability is less than the northern extra-tropics due to the larger ocean area. Considering the coolest and warmest two-decade periods of the instrument record, the global temperatures vary by only 80% of the ETNH. The global natural recovery from the LIA is estimated at 0.084 °C/century, which account for the proxy bias and the global adjustment.

Numerous papers have shown that the UHIE contaminates the instrument temperature record. A study by McKitrick and Michaels 2007 showed that almost half of the warming over land since 1980 in instrument data sets is due to the UHIE. The UHIE over land is about 0.14 °C/decade, or 0.042 °C/decade on a global basis since 1979.

The millennium warming and UHIE corrections reduce the temperature change between the two periods of the analysis due to greenhouse gases from 0.72 °C to 0.51 °C The best estimate of ECS considering the millennium warming cycle and the UHIE is 1.02 °C and the best estimate of TCR is 0.85 °C. […]

Ken Gregory continues in a comment:

“How many 100s of $billions have they wasted?”

Bloomberg reports that the total renewable energy investment from 2004 to 2015 inclusive was US$ 2672 Billion. Graph:

Pew Energy Trust gives lower annual numbers. They report the total renewable energy investment from 2004 to 2014 inclusive was US$ 2189 Billion.

A new study by Ferroni and Hopkirk estimates the ERoEI (energy gathered/energy invested) of temperate latitude solar photovoltaic (PV) systems to be 0.83.

Wind energy is very expensive when considering the cost imposed on the electrical grid and backup systems due to the extreme variability and unreliability. So yes, most of that investment is wasted.

Yet more on the waste:
