A History Of Scientific Uncertainties (on their way to policymaking oblivion)

I know this story well about climate science. I am pretty sure it happens all the time in every scientific field that has social implications.

  1. The scientific paper details the uncertainties
  2. The IPCC chapter mentions the uncertainties
  3. The IPCC SPM (summary for policymakers) contains some indication of the uncertainties inside one item in the bibliography
  4. The Press Release doesn’t have space for the uncertainties apart from a side remark in the middle of the text
  5. The interviewed scientist is not asked about the uncertainties
  6. The journalistic article isn’t interested in the uncertainties
  7. The policymaker either doesn’t know the uncertainties exist, or pivots all his/her career about some of the uncertainties as reported to him/her third- or fourth-hand.

Broken telephones all around…

THIS IS The #Climate Question

Everything else, is a corollary….

From Bishop Hill’s “Nobel laureate on temperatures” (Feb 2012):

The question is not whether temperatures have risen or whether mankind has affected the climate. Temperatures have always risen and fallen and mankind has always affected the climate. The question is whether we have a problem on our hands. The poor performance of the climate models suggests that the problem is much less than we have been led to believe.

Missing Heat 3 – Implications For Policymaking

Trenberth’s “missing heat” should be a problem of physics, only it’s handled by amateur homeo-climate-paths.

Actually, it’s much more than a problem of physics. It has vast policy implications.

If models are not useful in a decadal timescale, such as they can predict a strong warming for a period of minimal or even no warning, then what use is there for models? What government (apart from North Korea…) would make it difficult for people to heat up their homes in the next decade with the explanation that is going to be warm in 2070 anyway?

People do not average-out their lives across decades or centuries: each and every one of us have to go through each and every day first.

If I freeze to death today at -10C, I will not enjoy the warmth of July at +30C even if the average is +10C, perfectly compatible with human life. The same can be said of plants and animals. If I plant an olive tree in my London garden, it will die of cold in February even if the yearly average is in theory just enough to make olive trees survive in the open. If a nasty mosquito species migrates from warmer places during an August heatwave, still if that species cannot survive the following winter it will not be around until next migration opportunity during a future heatwave.

A purely statistical, multi-year approach to modelling the climate is in theory useless for policymaking (similar considerations could be made for non-regional projections, but that is too long a story here – read “How Space-Time Digested AGW” if interested). And if we end up with 15 years of incorrect projections without even a volcano for an excuse, then whatever physical explanation there is, policymakers would be much wiser in keeping climate scientists at arm’s length.
