Reasons Why Regulating CO2 Emissions Needs to be Reconsidered - Roy Spencer, PhD

Today, the Washington Post is reporting the EPA Administrator is considering recommending to the White House that the EPA’s 2009 CO2 Endangerment Finding be rescinded.  

Let’s look at a few of the reasons why this might be a good thing to consider.

• The Science

The science of human-caused climate change is much more uncertain that you have been led to believe. The globally-averaged surface temperature of Earth seems to have warmed by 1 deg. C or so in the last century...But whatever the level of warming, it might well be mostly human-caused.

• But we don’t really know.

As I keep pointing out, the global energy imbalance caused by increasing human-caused CO2 emissions (yes, I believe we are the cause) is smaller than the accuracy with which we know natural energy flows in the climate system. This means recent warming could be mostly natural and we would never know it.
I’m not claiming that is the case, only that there are uncertainties in climate science that are seldom if ever discussed...
