As predicted in 1967 by Manabe and Wetherald , the stratosphere has been cooling. The dominant factors are changes in CO2 (a cooling), ozone depletion (a cooling), warming from big volcanoes, and oscillations related to the solar cycle. Thompson et al. We are using the NOAA-STAR version 3.0 of these products (Zou et al.,

I had reason to be reviewing the history of MSU satellite retrievals for atmospheric temperatures recently. McNider and Christy, Feb 19th 2014, Wall Street Journal Most of the op-ed is a rather tired rehash of faux outrage based on a comment made by John Kerry (the then Secretary of State) and we can skip right past that.

Since this is a somewhat differently designed ensemble, I’ll plot that similarly (45 simulations), and note too that these are global means, again, for the corrected-TMT product (for the historical and SSP2-45 scenarios after 2014).

Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

This, astronomers believe, allowed the cloud to cool and condense into dust that blocked some of Betelgeuse’s light. The satellite was launched in 2014 and is in geostationary orbit 35,786 km above the western Pacific. The satellite revealed that the star itself cooled by 140 °C. Stellar background.

The observed reduction in surface warming trend over the period 1998 to 2012 as compared to the period 1951 to 2012, is due in roughly equal measure to a reduced trend in radiative forcing and a cooling contribution from natural internal variability, which includes a possible redistribution of heat within the ocean ( medium confidence ).
