The United Nations isn't the only group hosting a climate change conference in Paris next week.

An ensemble of scientists called the International Climate Science Coalition is holding its own event to challenge the climate "consensus."

The purpose of the meeting, scheduled for Dec. 1-3, is to assert to world that the climate change debate is not settled, even as many scientists today contend greenhouse gases emitted from the burning of manmade fossil fuels are driving climate change. On the conference website, a list of 10 questions are posed to the U.N. Framework Convention on Climate Change and its supporters, asking them to produce "observational evidence" on manmade climate change-related issues including sea level rise, glacier retreat and increased severity in hurricanes and other extreme weather events.

Tom Harris, the executive director of ICSC, said the questions were previously issued as a challenge in 2009 as the U.N. held a climate conference in Copenhagen, Denmark.

"Endorsed by 161 science and technology experts well qualified in climate science, the challenge was presented as an open letter submitted to U.N. Secretary General Ban Ki-moon and reported on by prominent media across the world," said Harris. "Mr. Ban never responded or even acknowledged the scientists' open letter."

The event will feature prominent scientists and climate change skeptics including Bob Carter, professor and former head of James Cook University's Department of Earth Sciences in Australia, and Nils-Axel Morner, emeritus professor of paleogeophysics and geodynamics at Stockholm University in Sweden.

Also slated to speak is Patrick Moore, co-founder and ex-director of Greenpeace, an environmental organization that subscribes to the belief that manmade emissions drive climate change. Moore says he left Greenpeace in 1986 because the group "took a sharp turn to the political left." Greenpeace claims that since leaving the organization, Moore speaks against climate change and for "financial gain" and "often misrepresents himself in the media as an environmental 'expert' or even an 'environmentalist,' while offering anti-environmental opinions on a wide range of issues and taking a distinctly anti-environmental stance."

The ICSC has been accused of being more of a public relations organization than one promoting science. But in its mission statement, the ICSC says it is a "non-partisan group of independent scientists, economists and energy and policy experts" that aims to move the debate "away from implementation of costly and ineffectual 'climate control' measures" and assist "vulnerable peoples to adapt to climate variability and continuing scientific research into the causes and impacts of climate change."

"We are back this year to ask the same and more questions, and challenge the climate 'consensus' in Paris at [The U.N. Climate Change Conference] with alternative, more realistic climate hypotheses," said Rev. Philip Foster, lead coordinator of the ISSC conference.

"Across the world hundreds of billions of pounds are diverted from important humanitarian and other concerns to futile attempts to control the world's climate," Foster continued. "As will be demonstrated at the [ICSC] conference, this climate scare has become the greatest scandal in the history of science."
