New misguided interpretations of the greenhouse effect from William Kininmonth

Real Climate

When looking at the effect of changes in greenhouse gases, one must look at how their forcing corresponds to the energy balance at the top of the atmosphere. It is also important that such calculations and models are thoroughly evaluated (Benestad et al., 2015) , and this is also applies to Kininmonth’s calculations. References. Benestad, D.

The CO2 problem in six easy steps (2022 Update)

Real Climate

However, that was written in 2007 – 15 years ago! This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). Step 1: There is a natural greenhouse effect.

A CERES of fortunate events…

Real Climate

The CERES estimates of the top-of-atmosphere radiative fluxes are available from 2001 to the present. We can explore the issues and pitfalls of this using the ‘simple model’ of the greenhouse effect we explored back in 2007. The simplest model for the greenhouse effect. Two layers, albedo, and one LW absorber.

The Colorado River Basin’s Daunting New Math

Circle of Blue

Next week the federal government, for the first time, will likely declare a Tier 1 shortage on the lower Colorado River, opening a new chapter in the beleaguered river’s history and illustrating its vulnerability in a region that is drying because of the buildup of heat-trapping gases in the atmosphere.

A distraction due to errors, misunderstanding and misguided Norwegian statistics

Real Climate

are used all over the world, based on calculations that quantify the effects of physical mechanisms and the way different parts of the atmosphere are connected to each other. The physics-based models describe how energy flows through the atmosphere and ocean, as well as how the forces from different air masses push against each other.
