“Once you start doubting, just like you’re supposed to doubt. You ask me if the science is true and we say ‘No, no, we don’t know what’s true, we’re trying to find out, everything is possibly wrong’ … When you doubt and ask it gets a little harder to believe. I can live with doubt and uncertainty and not knowing. I think it’s much more interesting to live not knowing, than to have answers which might be wrong.” Richard Feynman (1981)

5.1 Introduction

The 1990s discovery of multidecadal variability (see Part IV) showed that the science of climate change is very immature. The answer to what was causing the observed warming was provided before the proper questions were asked. Once the answer was announced, questions were no longer welcome. Michael Mann said of a skeptical Judith Curry: “I don’t know what she thinks she’s doing, but it’s not helping the cause, or her professional credibility” (Mann 2008). But as Peter Medawar (1979) stated, “the intensity of a conviction that a hypothesis is true has no bearing over whether it is true or not.” Scientists’ opinions do not constitute science, and a scientific consensus is nothing more than a collective opinion based on group-thinking. When doubting a scientific consensus (“just like you’re supposed to doubt,” as Feynman said) becomes unwelcome, the collective opinion becomes dogma, and dogma is clearly not science.

“The atmospheric heat transport on Earth from the Equator to the poles is largely carried out by the mid-latitude storms. However, there is no satisfactory theory to describe this fundamental feature of the Earth’s climate.” Leon Barry, George C. Craig & John Thuburn (2002)

3.1 Introduction

Nearly all the energy that powers the climate system and life on Earth comes from the sun. Incoming solar radiation is estimated at 173,000 TW. By contrast geothermal heat flow from radiogenic decay and primordial heat is estimated at 47 TW, human production of heat at 18 TW, and tidal energy from the Moon and the Sun at 4 TW. Other sources of energy, like solar wind, solar particles, stellar light, moonlight, interplanetary dust, meteorites, or cosmic rays, are negligible. Solar irradiance, thus, constitutes over 99.9 % of the energy input to the climate system… [See the rest of the post on Climate Etc.]
