I think the focus should be on understanding climate — and unfortunately you can't do that without a theory that predicts
substantial warming due to anthropogenic CO2.
Should you not have learned by now that no theory has yet been put forth which can account for the 20th / 21st century pattern without
a substantial warming due to GHG increase?

Similarly, in some countries in Southern Europe (Spain, Portugal, Greece) the initial increase in impacts at 1.5 °C turns into more uncertain projections for higher
warming levels,
due to a
substantial reduction in annual rainfall.
Just as many of the home runs hit by a baseball player on steroids were almost certainly
due to the taking of steroids — even if you can't prove that any one home run resulted from it — so too is it likely that the record - breaking heat we are seeing in the U.S. this summer of 2012 is very likely
due, in
substantial part, to the impact of human - caused climate change and global
warming.
This
warming is
due, to a
substantial extent to human activity, particularly emissions of greenhouse gases 3.
So, we can see that both the Unadjusted and the Partially adjusted datasets show a
substantial warming bias
due to poor station sitings.
Whilst economic growth is projected to significantly reduce childhood stunting, climate change is projected to reverse these gains in a number of regions:
substantial increases in stunting
due to malnutrition are projected to occur with
warming of 2 °C to 2.5 °C, especially in Sub-Saharan Africa and South Asia, and this is likely to get worse at 4 °C.
Tett SFB et al., JGR 2002 (Estimation of natural and anthropogenic contributions to twentieth century temperature change,) says «Our analysis suggests that the early twentieth century
warming can best be explained by a combination of
warming due to increases in greenhouse gases and natural forcing, some cooling
due to other anthropogenic forcings, and a
substantial, but not implausible, contribution from internal variability.
There is a
substantial case for linking anthropogenic impacts of Antarctic stratospheric ozone depletion (
due to CFCs) and greenhouse
warming on the southern hemisphere atmospheric circulations and Australian climate.
