Adapting to climate change requires the further development and use of fossil fuels

The single thing that differentiates the human species from every other known species on earth has been the control and use of fire.The step change then from primitive to modern humans has been due not least to the control and development of the combustion process and the utilisation of fossil fuels. This in turn has multiplied many times the intensity of energy available to be harnessed by man. I would suggest that the human capability of handling change is largely a function of the power intensity available.

Fossil fuels have been demonised (by association with carbon dioxide emissions) for the last 30 years. In spite of that most  of the growth in the developing world has been – and continues to be – powered by fossil fuels. Fortunately the lack of evidence of any significant linkage between man-made carbon dioxide and global warming  (which is still the politically correct ideology) is beginning to be realised. The unnecessary, misplaced and ineffective increase of electricity prices in countries which have curtailed their use of fossil fuels has prolonged the recession and has cost many millions of jobs.

We have now had almost 20 years with the highest level ever of fossil fuel utilisation but “global temperature” has remained stubbornly static. In the last decade global temperatures have declined slightly. The hypothesised link between man-made carbon dioxide (which constitutes only about 3% of carbon dioxide emissions) and global temperature is well and truly broken. All the various climate computer models – which build on this link being amplified – have failed miserably.

The indicators of a global cooling cycle having started are piling up.

  1. There is more ice in the antarctic than has ever been measured
  2. There is more ice in the arctic than about a decade ago
  3. Total ice cover is higher now than has ever been measured
  4. Ice cover on the Great Lakes reached levels not seen for over 50 years and has persisted into the spring (even summer) later than has been observed for at least 40 years.
  5. The expected super El Nino forecast for this year has been dampened by a cooling Pacific and only a mild El Nino event – if at all – is now to be expected
  6. Sea level rises are no different to the long term average for sea level recovery since the last glacial minimum and may even have slowed.
  7. The deep oceans are cooling and are no repository of “hidden heat”
  8. The net cooling effect of clouds has been underestimated in nearly all models and cloud cover over the world is increasing (slightly).
  9. Man made water vapour is of greater significance than man made carbon dioxide for climate effects. But man made water vapour is almost insignificant compared to the water vapour flux due to evaporation and respiration.
  10. Solar effects are virtually ignored by all climate models but the sun does not much care for models and is reaching a low level of activity comparable to the Dalton or Maunder Minima.

Crying wolf about global warming has been the politically correct thing to do for 3 decades. Before that it was politically correct to be alarmist about the coming ice age. No doubt all the old fears about an ice age can be dusted off and recycled.

Climate change has been the most powerful force which has shaped human evolution and expansion. Sea level changes and patterns of precipitation and desertification have driven both evolution and migrations. Sea level during an ice age is about 120 m lower than it is today. More land is exposed in equatorial and tropical regions during a glacial period while land is rendered uninhabitable by the ice sheets of the north. But even primitive humanity survived during the glacials.

It is the global cooling cycles and not global warming cycles which will place the greatest demands on farming and energy. The greatest sea level change that humanity has had to – and will have to – adapt to  is the 120 m difference between glacial and interglacial conditions. During an ice age precipitation will drop sharply and river water flows will decline. Hydro power will all but dry up. It is the inevitable coming of the next ice age that will pose the real challenge – not the 1 m sea level rise that may come with another warming cycle. And when the ice age comes again it will be fossil fuels which will keep the home fires burning. It is the further exploitation of nuclear energy and fossil fuels in all its forms – coal, oil, natural gas, shale gas, gas from methane hydrates – that will be needed. It is the availability of power at the intensities provided by nuclear power and fossil fuel combustion which is what will provide humans with the wherewithal to cope with climate change, whether warming or cooling, but especially when the next ice age begins.

Whatever the alarmists would have us do in the short term, reality will eventually bite. The use of fossil fuels will – thankfully – continue as will the exploration for new sources of gas. The next generation of nuclear power plant will be developed – even though nuclear alarmism has led to a dearth of nuclear engineers. No doubt some market niches will be filled by wind and solar power but that will not be very significant in the large picture.
