Radiative energy flux variations from 2000 – 2020
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. In the former…
A pertinent climate question
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?
Radiative Forcing, Radiative Feedbacks and Radiative Imbalance – The 2013 WG1 IPCC Report Failed to Properly Report on this Issue

The effectiveness of CO2 as a greenhouse gas becomes ever more marginal with greater concentration
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…
Dispelling myths about global warming
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…
Yet another study shows lower climate sensitivity
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…
IPCC Chapter 11 – Bankruptcy Protection

The Forcing Conundrum
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…
Inconvenient conclusions in a new climate and land use paper
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,…
No wonder 'climate' wasn't mentioned in the presidential debate
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…
Some thoughts on radiative transfer and GHG's
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…
Important New Paper on the Nocturnal Boundary Layer, Mixing, and Radiative Forcing as it applies to GHCN weather stations
From Dr. Roger Pielke Sr. comes word of an important new paper that shows how the air near the ground (boundary layer) is highly affected by sensitive nighttime dynamics, which…
