The Paris Climate Challenge

In association with the
Independent Committee on Geoethics www. www.geoethic.com
and the Collectif des Climato Réalistes www.www.skyfall.fr
Summary Statement
Over thirty years of intense (and extremely expensive) research has totally failed to produce any evidence that human emissions of CO2 are driving climate. CO2 is not a danger to but a benefit for all life on our planet.
We call on governments, NGOs and universities to stop pursuing policy and dogma based ‘evidence’ gathering.
• That they stop scaremongering.
• That they dissolve the IPCC and the UNFCCC.
• That governments focus instead on encouraging means of ensuring that under-developed and developing nations have full access to the cheapest reliable energy (particularly electricity), regardless of whether fossil fuels are used, so as to improve their access to clean water, low pollution cooking facilities and good medical services.
• That once respected academic institutions and scientific publications put their own houses in order and once again allow the free exchange of scientific ideas and results without prejudice.
• That those involved in alleged cases of scientific fraud, which have resulted in huge financial costs, causing greater poverty and many deaths among the poorest, be brought before the relevant Court of Law.

In 2009 we laid down the Copenhagen Climate Challenge, when we asked UN Secretary-General Ban Ki-Moon to answer 10 questions about climate. We’re back to ask the same and more questions, and challenge the climate ‘consensus’ in Paris at COP 21 with alternative climate hypotheses. If you have something to say in Paris, we still have places for a few more speakers. Take some time to navigate our pages, you can leave a comment if you’d like to say something in response to the articles backing up our 10 questions to Ban Ki-Moon below.


His Excellency Ban-Ki Moon,
Secretary-General, United Nations,

Dear Secretary-General,

Climate change science is in a period of ‘negative discovery’ – the more we learn about this exceptionally complex and rapidly evolving field the more we realize how little we know. Truly, the science is NOT settled.

Therefore, there is no sound reason to impose expensive and restrictive public policy decisions on the peoples of the Earth without first providing convincing evidence that human activities are causing dangerous climate change beyond that resulting from natural causes. Before any precipitate action is taken, we must have solid observational data demonstrating that recent changes in climate differ substantially from changes observed in the past and are well in excess of normal variations caused by solar cycles, ocean currents, changes in the Earth’s orbital parameters and other natural phenomena.

We the undersigned, being qualified in climate-related scientific disciplines, challenge the UNFCCC and supporters of the United Nations Climate Change Conference to produce convincing OBSERVATIONAL EVIDENCE for their claims of dangerous human-caused global warming and other changes in climate.Projections of possible future scenarios from unproven computer models of climate are not acceptable substitutes for real world data obtained through unbiased and rigorous scientific investigation.

Specifically, we challenge supporters of the hypothesis of dangerous human-caused climate change to demonstrate that:

  1. Variations in global climate in the last hundred years are significantly outside the natural range experienced in previous centuries;
  2. Humanity’s emissions of carbon dioxide and other ‘greenhouse gases’ (GHG) are having a dangerous impact on global climate;
  3. Computer-based models can meaningfully replicate the impact of all of the natural factors that may significantly influence climate;
  4. Sea levels are rising dangerously at a rate that has accelerated with increasing human GHG emissions, thereby threatening small islands and coastal communities;
  5. The incidence of malaria is increasing due to recent climate changes;
  6. Human society and natural ecosystems cannot adapt to foreseeable climate change as they have done in the past;
  7. Worldwide glacier retreat, and sea ice melting in Polar Regions , is unusual and related to increases in human GHG emissions;
  8. Polar bears and other Arctic and Antarctic wildlife are unable to adapt to anticipated local climate change effects, independent of the causes of those changes;
  9. Hurricanes, other tropical cyclones and associated extreme weather events are increasing in severity and frequency;
  10. Data recorded by ground-based stations are a reliable indicator of surface temperature trends.

It is not the responsibility of ‘climate realist’ scientists to prove that dangerous human-caused climate change is not happening. Rather, it is those who propose that it is, and promote the allocation of massive investments to solve the supposed ‘problem’, who have the obligation to convincingly demonstrate that recent climate change is not of mostly natural origin and, if we do nothing, catastrophic change will ensue. To date, this they have utterly failed to do.
