Global warming slowdown probably due to natural cycles, study finds

Sorry folks [image credit: wikia]

The Guardian newspaper finally facing up to climate reality? Well, after a fashion. Their global warming can may have been kicked down the road for a while, that’s all.

The idea that natural variation could make temperatures go up as well as down is still not for discussion in their biased climate world.

Guardian report: Manmade global warming over the past decade has probably been partly offset by the cooling effect of natural variability in the Earth’s climate system, a team of climate researchers have concluded.

The finding could help explain the slowdown in temperature rises this century that climate sceptics have seized on as evidence climate change has stopped, even though 14 of the 15 hottest years on record have happened since 2000.

The authors of the new paper describe the slowdown, sometimes called a global warming hiatus or pause, as a “false pause”. They warn that the natural cycles in the Pacific and Atlantic that they found are currently having an overall cooling effect on temperatures will reverse in the coming decades – at which point warming will accelerate again.

AN OPEN LETTER TO THE PRIME MINISTER ABOUT CLIMATE CHANGE AND ENERGY POLICIES

Dear Prime Minister,

Like you I read PPE at Oxford and I was lucky enough to be taught Economics by Professor Wilfred Beckerman. He has an interest in the economics of environmentalism, having worked in that field with the World Bank in the 1960s, advised the Labour Party on it and he was a member of the Royal Commission on Environmental Pollution from 1970 to 1973. He wrote an excellent book in 1974 called “In Defence of Economic Growth” which was a rebuttal of the famous Club of Rome 1972 book “The Limits to Growth”.

In 2002, Prof. Beckerman published a book called “A Poverty of Reason: Economic Growth and Sustainable Development”. If you or your advisers on environmental policies haven’t read it before, I thoroughly recommend it as a succinct and massively sensible analysis of many environmentalists’ arguments by a brilliant economist and excellent teacher. He is still going strong at 87; he’s still teaching at UCL, mainly on ethical issues in Economics which he touches on in this book when addressing the mistakes made by many environmentalists about intergenerational ethics, rights and basic economics when considering issues like resource depletion, climate change and the precautionary principle.

Uncertainty: The origin of the increase in Atmospheric CO2

One of the ‘Tablets of Stone’ in the argument for ‘Anthropogenic Global Warming’ is that human emission of co2 through the burning of fossil fuel is responsible for the increase in the atmospheric level of this trace gas since pre-industrial times, which now constitutes 0.039% of Earth’s atmosphere. It is claimed that this can be logically deduced and calculated and  there is no doubt we are the guilty species.

But there’s a problem…

Roy Clark: A null hypothesis for CO2

Roy Clark phd has spent the last three years researching and writing this paper. It confirms my own research on the average sunspot number and the ocean equilibrium value, as well as extending my thoughts on the multi-decadal retention of heat energy in the worlds oceans into properly quantified analysis. This has enabled Roy to make much more detailed and definite statements about the relative importance of co2 in the atmosphere as an agent of climate change than I could. The paper is pay for, but at least the journal (Energy and Environment) has been consistently open minded about reviewing and publishing those scientists whose research findings are sometimes at odds with the so called mainstream consensus on this issue. The paper runs to 30 pages with many graphs and digrams and represents much better value and more bang for your buck than any other published paper on the subject I know of.  A version of the CA climate article should be published on the SSPI (Science and Public Policy Institute) website quite soon and I will revisit this paper after that has gone online.

Abstract:

Energy transfer at the Earth’s surface is examined from first principles. The effects on surface temperature of small changes in the solar constant caused by the sunspot cycle and small increases in downward long wave infrared (LWIR) flux due to a 100 ppm increase in atmospheric CO2 concentration are considered in detail. The changes in the solar constant are sufficient to change ocean temperatures and alter the Earth’s climate.

Figure 4

The surface temperature changes produced by an increase in downward LWIR flux are too small to be measured and cannot cause climate change. The assumptions underlying the use of radiative forcing in climate models are shown to be invalid. A null hypothesis for CO2 is proposed that it is impossible to show that changes in CO2 concentration have caused any climate change, at least since the current composition of the atmosphere was set by ocean photosynthesis about one billion years ago.
