International Climate Science Coalition (ICSC)
The International Climate Science Coalition (ICSC) describes itself  as “a non-partisan group of independent scientists, economists and energy and policy experts who are working to promote better understanding of climate science and policy worldwide.”
ICSC was launched in 2007 by the New Zealand Climate Science Coalition  when the group “received such positive feedback from around the world … that they decided they needed an international group.” Their aim is “moving the debate away from implementation of costly and ineffectual 'climate control' measures.”
According to their website, “ICSC also focuses on publicizing the repercussions of misguided plans to solve the 'climate crisis'. This includes, but is not be limited to, the dangerous impacts of attempts to replace conventional energy sources with wind turbines, solar power, biofuels and other ineffective and expensive energy sources.”
ICSC describes its purpose as providing a “international response to what has become a very international, heavily funded climate alarmist effort around the world.” ICSC has created the Australian Climate Coalition  as well as the Climate Science Coalition of America whose executive director is Steve Goreham . 
Stance on Climate Change
ICSC lists the following as their “core principles ” regarding climate science:
1. Global climate is always changing in accordance with natural causes and recent changes are not unusual.
2. Science is rapidly evolving away from the view that humanity's emissions of carbon dioxide and other 'greenhouse gases' are a cause of dangerous climate change.
3. Climate models used by the IPCC* fail to reproduce known past climates without manipulation and therefore lack the scientific integrity needed for use in climate prediction and related policy decision-making.
4. The UN IPCC Summary for Policymakers and the assertions of IPCC executives too often seriously mis-represent the conclusions of their own scientific reports.
5. Claims that ‘consensus’ exists among climate experts regarding the causes of the modest warming of the past century are contradicted by thousands of independent scientists.
6. Carbon dioxide is not a pollutant - it is a necessary reactant in plant photosynthesis and so is essential for life on Earth.
7. Research that identifies the Sun as a major driver of global climate change must be taken more seriously.
8. Global cooling has presented serious problems for human society and the environment throughout history while global warming has generally been highly beneficial.
9. It is not possible to reliably predict how climate will change in the future, beyond the certainty that multi-decadal warming and cooling trends, and abrupt changes, will all continue, underscoring a need for effective adaptation.
10. Since science and observation have failed to substantiate the human-caused climate change hypothesis, it is premature to damage national economies with carbon taxes, emissions trading or other schemes to control 'greenhouse gas' emissions.
According to ICSC , “Since its formation in 2007, ICSC has never received financial support from corporations, foundations or governments. 99% of all donations have come from private individuals in the United Kingdom, New Zealand, United States and Canada.”

The ICSC is listed as an official Co-sponsor  of the Heartland Institute's Seventh International Conferenece on Climate Change (ICCC7).
ICSC was a sponsor  of the Heartland Institute's 2009 International Conference on Climate Change.
Collectively sponsors for the conference received over $47 million from oil companies and right-wing organizations.
December 8, 2009
ICSC hosted the “Copenhagen Climate Challenge ”  which was signed  by numerous prominent climate change skeptics. 
See the video  (hosted by CFACT ) of Tom Harris presented the Climate Challenge.
March 4, 2008
ICSC promotes the “Manhattan Declaration ,” a document that was presented at the Heartland Institute's 2008 International Conference on Climate Change.
The Declaration states that “That there is no convincing evidence that CO2 emissions from modern industrial activity has in the past, is now, or will in the future cause catastrophic climate change” and “That human-caused climate change is not a global crisis.”
It concludes “That all taxes, regulations, and other interventions intended to reduce emissions of CO2 be abandoned forthwith.” 
At the 2008 International Conference on Climate Change” hosted by the Heartland Institute, ICSC Executive Director Tom Harris gave a speech in which he discussed what he called “information sharing” and “coordinated local activism”: (Archived mp3 )
”[…] We need regular high-impact media coverage of the findings of leading scientists — not just one or two publications, but we need to have hundreds all over the world. We need to have a high degree of information sharing and cooperation between groups, so that when Vincent Gray for example has an article published in New Zealand, we can take the same piece and we can (say) submit it to newspapers all over North America and Europe.
“Then we have a nicely well-coordinated response, where letters to the editor and phone calls are made. “Congratulations on publishing that article!” You know, it's interesting because I've had many of my articles opposed so strongly, by environmentalists through phone calls and letters to the editor, that they just simply dry up, they just won't publish us again. So this does have feedback, I mean, these are people that run these newspapers, and they're scared, and impressed, and encouraged, depending on the feedback they get.
We have to have grassroots organizations doing exactly that kind of thing: coordinated local activism.”
