Broad consistency between patterns of fossil fuel emissions and atmospheric CO2

by Guido van der Werf

The 200% increase in fossil fuel emissions Murry Salby claims is about 20% in reality, and the constant CO2 growth rate he found actually increased by roughly 20% as well over the same time period.

Are energy budget climate sensitivity values biased low?

by Nic Lewis

In a recently published paper (REA16),[i] Mark Richardson et al. claim that recent observation-based energy budget estimates of the Earth’s transient climate response (TCR) are biased substantially low, with the true value some 24% higher.
