Climate skeptics hold their own Copenhagen conference

December 9, 2009

With the world’s eyes firmly fixed on the U.N. Climate Conference in Copenhagen it is easy to forget that there remains a significant group of scientists and politicians who do not accept that humanity’s emissions of greenhouse gases are the primary cause of climate change.

These climate skeptics are in Copenhagen too and they held their own two-day conference not far from the Bella Center, home of the main summit. The Copenhagen Climate Challenge brought together a cluster of scientists who believe the real causes of climate change are being overlooked, ignored and even purposefully distorted.

They presented their evidence and called on world leaders to recognise that there is in fact no scientific consensus on climate change and asked that their dissenting views are given a fair hearing.

We spoke to some of the attendees. Here is a video clip of Craig Rucker, Director of the Committee For a Constructive Tomorrow (CFACT), the organisers of the Climate Challenge Conference, and another of Professor Niklas Nils-Axel Mörner, an expert on world sea levels.

Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and out-going infrared (thermal) radiation that are part of Earth’s energy balance. Changing the atmospheric abundance or properties of these gases and particles can lead to a warming or cooling of the climate system. Since the start of the industrial era (about 1750), the overall effect of human activities on climate has been a warming influence. The human impact on climate during this era greatly exceeds that due to known changes in natural processes, such as solar changes and volcanic eruptions.

There is strong evidence that global sea level gradually rose in the 20th century and is currently rising at an increased rate, after a period of little change between AD 0 and AD 1900. Sea level is projected to rise at an even greater rate in this century. The two major causes of global sea level rise are thermal expansion of the oceans (water expands as it warms) and the loss of land-based ice due to increased melting.

Observations show a global-scale decline of snow and ice over many years, especially since 1980 and increasing during the past decade, despite growth in some places and little change in others. Most mountain glaciers are getting smaller. Snow cover is retreating earlier in the spring. Sea ice in the Arctic is shrinking in all seasons, most dramatically in summer. Reductions are reported in permafrost, seasonally frozen ground and river and lake ice. Important coastal regions of the ice sheets on Greenland and West Antarctica, and the glaciers of the Antarctic Peninsula, are thinning and contributing to sea level rise. The total contribution of glacier, ice cap and ice sheet melt to sea level rise is estimated as 1.2 ± 0.4 mm yr−1 for the period 1993 to 2003.

One may only hope the denialists are being well-paid by their oil-drilling corporate masters for their hard work.
