The cause of global warming is still under debate.” – Choi and Manousiouthakis, 2022

The time span of 20 years is still too short to be able to decide conclusively whether the current heating phase is a temporary or permanent development...

How much of a change in cloudiness would it take to account for the 0.53 W/m2 increase in TOA radiative forcing since 2003?

Guest essay by Roger A. Pielke Sr. Main Points 1. The difference in ocean heat content at two different time periods provides the global average radiative imbalance over that time [within the uncertainty of the ocean heat...

The new RCPs are not projections, probabilities, prophecies or pathways – they might possibly be potentialities. Guest essay by Barry Brill The IPCC begins with science: “In sum, a strategy must recognise what is possible....

Guest essay by Nic Lewis The Otto et al. paper has received a great deal of attention in recent days. While the paper’s estimate of transient climate response was low, the equilibrium/effective climate sensitivity figure...

Guest Post by Willis Eschenbach Anthony put up a post titled “Why the new Otto et al climate sensitivity paper is important – it’s a sea change for some IPCC authors” The paper in question is “Energy...

The political target of limiting the effect of Man-made global warming to only +2⁰C can never be attained. Guest essay by Ed Hoskins According to well understood physical parameters, the effectiveness of CO2 as a greenhouse...

CO2 did not drive the rapid warming of the 20th century. Story submitted by Stan Robertson The difference between a good idea and a bad idea is often a quantitative matter. For example, many people would think it a good …...

Global warming less extreme than feared? Policymakers are attempting to contain global warming at less than 2°C. New estimates from a Norwegian project on climate calculations indicate this target may be more attainable...

Guest post by David M. Hoffer IPCC reports AR1 through 4 were published in relative obscurity. ClimateGate and the emergence of the blogosphere as the primary forum for debate of the science and public policy intersection...

Guest Post by Willis Eschenbach. For all of its faults, the IPCC (Intergovernmental Panel on Climate Change) lays out their idea of the climate paradigm pretty clearly. A fundamental part of this paradigm is that the long-term...

Dr. Roger Pielke Sr. sends word of this new paper now in early release at the Journal of Climate. The paper suggests humans have strong impacts on the local climate, but not always through the pathways commonly touted as...

While my favorite tweet this morning called climate “the third rail” (i.e. don’t touch the electrified rail or it will kill your presidential bid, there’s even a Wiki entry on it) the reality seems...

Guest post by Reed Coray The following example illustrates the issues I have with reasoning often used to argue that increasing the amount of CO2 in the Earth’s atmosphere will increase both the Earth’s surface temperature...
