How not to science

Real Climate

I had reason to be reviewing the history of MSU satellite retrievals for atmospheric temperatures recently. Remember ‘satellite cooling’?]. This was before Wentz and Schabel (1998) pointed out that orbital decay in the NOAA satellites was imparting a strong cooling bias (about 0.12 and RSS v3.3 and 0.08 +/- 0.05

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

The problems with the SPM are similar those from the previous fifth assessment report which prompted me to write a post in 2013. I think in hindsight that my concerns from 2013 to some extent were supported by the fact that the IPCC organised an Expert Meeting on Communication, Oslo, Norway, 9–10 February 2016.

Should the official Atlantic hurricane season be lengthened?

Real Climate

But it emphasizes an important point about the relationship between SST and hurricane behavior in general: The hurricane response to SST changes depends on what caused the SST changes ( Emanuel and Sobel 2013 ). The difference is due largely to the differences in the regional atmospheric response that occurs in concert with the SST warming.

As Soon as Possible

Real Climate

If the sun was driving the warming, we’d see it in the stratospheric temperatures (which are cooling in line with expectations from the impact of CO2, not warming due to the supposed increase in solar activity). 4171-4176, 2013.

A deep dive into the IPCC’s updated carbon budget numbers

Real Climate

And since the first IPCC estimates published in 2013, we have learned a lot and have gotten much better at estimating remaining carbon budgets. IPCC reported carbon budgets for the first time in 2013. in 2018, but they represent a significant update since AR5 in 2013. In the 2018 IPCC Special Report on Global Warming of 1.5°C

Why is future sea level rise still so uncertain?

Real Climate

Meanwhile, note that the factors listed above involve the whole Earth system: the oceans, the cryosphere, the atmosphere, the solid earth and lithosphere, and a full range of scales, from the city block and shoreline, to ice dynamics that change over kilometers, to GRD footprints, to the whole global ocean. 375-393, 2013.

Getting physical with the climate crisis

Physics World

As air sunk through the atmosphere, it got squeezed and heated. Extreme heat is not just an abstract notion: if we can’t cool our bodies enough, we’re in danger of neurological failure, organ failure and even death, with the risks highest for children and the elderly.
