New Scientist blog: CEO of “Good” Energy complains that sceptics are resorting to emotion rather than science

September 23, 2011

Juliet Davenport, founder and CEO of something carrying the subjective and emotive name “Good” Energy writes in the New Scientist blog today bemoaning the fact that climate sceptics are winning the argument by the use of emotion rather than science!!

Scientists – she believes – are not doing enough to help her cause. But she might carry a little more credibility if she attempted to use science rather than dogma and consensus. And of course if she did not have a vested interest in extorting subsidies from taxpayers. Clearly Al Gore has failed her in being “charismatic and campaigning”- but then he is no scientist and perhaps he does not count.

A charismatic campaigning voice from the scientific community would make a huge difference in helping to combat the small but vocal minority of sceptics who tend to resort to emotion rather than science to make their arguments. …….. 

…. I can’t help but think it would be better to see all government departments arguing more loudly about the long term benefits of tackling climate change and the transition to a low carbon economy. To do that convincingly, however, they need to have information at their fingertips. Scientists have a huge role to play here, debating and responding to claims made through the media and simplifying messages for the public. They need to make the case that a low-carbon economy is not only necessary for tackling climate change, but also that it is technologically possible.

If we are going to act in time on climate change, it is vital that we keep up the pressure on the government to form a policy framework that we can then deliver.

The coming gas glut and the availability of shale gas – now even in the UK – must be giving her nightmares. Without climate change alarmism and the demonisation of carbon dioxide, the cost of wind and solar power would make them non-starters.

But the tide is turning.

New Scientist: Climate change led to the “golden age” of human evolution

August 8, 2011

The New Scientist has been one of the high priests of the AGW doctrine and “global warming” has been a dirty word. It represents politically correct “establishment science” and generally shuns the scepticism and irreverence of the true scientist. It has been – and still is – extremely reluctant to admit to any weaknesses in AGW dogma or in any possible benefits of global warming. But as “global warming” has morphed to the less emotive “climate change” and it is becoming clearer that man-made emissions don’t even control global CO2 levels – let alone the climate – the “settled science” is being shown to be anything but settled. There are some slight signs that the New Scientist is positioning itself so that it can be found to be on the side of the good guys no matter what surprises the climate may have in store.

Change and variability in Plio-Pleistocene climates: Modelling the hominin response by Matt Grove is a new paper in the Journal of Archaeological Science.

  • The research expands a technique originally developed by theoretical biologists.
  • The technique distinguishes between climatic change and climatic variability.
  • Change results in directional selection; variability selects for plasticity.
  • Results suggest selection for plasticity increases c.2.3-2.5 mya.
  • This date range coincides with the evolution of Homo and the spread of the Oldowan.

Thank climate change for the rise of humans 05 August 2011 by Andy Coghlan

SOME claim climate change will destroy our species; now it seems it also helped forge it. The rapid fluctuations in temperature that characterised the global climate between 2 and 3 million years ago coincided with a golden age in human evolution.

Australopithecus africanus

The fossil record shows that eight distinct species emerged from one hominin species, Australopithecus africanus, alive 2.7 million years ago. The first members of our genus appeared between 2.4 and 2.5 million years ago, while Homo erectus, the first hominin to leave Africa, had evolved by 1.8 million years ago.

To work out whether climate had a hand in the speciation spurt, Matt Grove of the University of Liverpool in the UK turned to a global temperature data set compiled by Lorraine Lisiecki at the University of California, Santa Barbara. Lisiecki analysed oxygen isotopes in the shells of fossilised marine organisms called foraminifera. During glacial periods, the forams’ shells contain more of the heavier of two oxygen isotopes, as the lighter one is preferentially accumulated in snow and ice rather than the ocean.

Grove found that the mean temperature changed suddenly on three occasions during the last 5 million years. Each change was equivalent to the difference between glacial and interglacial temperatures – but none of these episodes coincided with the hominin “golden age”. What marked out this period was a greater range of recorded temperatures, suggesting it was a time of rapid but short-lived fluctuations in climate. Grove says such conditions would have favoured the evolution of adaptability that is a hallmark of the genus Homo (Journal of Archaeological ScienceDOI: 10.1016/j.jas.2011.07.002). Grove says the classic survival traits of H. erectus, forged during this period of change, include teeth suited for generalised diets and a large brain – both of which should have been advantageous at a time of swift climate change.

Oh dear ! Science in the service of totalitarianism

October 7, 2010

Fred Pearce in the New Scientist is at it again!

The world badly needs an independent carbon police to check the figures and catch the carbon frauds.

Can science deliver?

 

Carbon police?

 

Verifying national emissions requires both “bottom-up” independent oversight of the inventories, and better “top-down” monitoring of the atmosphere, says Matthias Jonas of the International Institute for Applied Systems Analysis in Laxenberg, Austria.

A new climate treaty will also need carbon sniffers in tropical forests, especially in countries that sign up to a part of the deal called REDD (Reduced Emissions from Deforestation and Forest Degradation). REDD would offer cash to countries that conserve their forests so they can soak up atmospheric CO2. This means knowing how much carbon is actually being absorbed by the forests. In August, a study of Peruvian forests by Greg Asner of Stanford University, California, found existing estimates of carbon stored and released could be out by as much as 50 per cent.

Enough said!

The Carbon Police mean business. Trees and plants not absorbing their required amount of carbon dioxide will be punished severely.
