Icecap is a blog that accepts the reality of global warming and the role of humans including greenhouse gas pollution. It promotes the idea of "a sudden climate shift that history tells us will occur again, very possibly soon." However, it argues that the threat of human-caused global warming is exaggerated. It was founded and run by Joseph D'Aleo. The name is a backronym of International Climate and Environmental Change Assessment Project. It was founded in 2006. They are a 501(c) tax-exempt, nonprofit corporation.
They describe themselves as: "Icecap is the portal to all things climate for elected officials and staffers, journalists, scientists, educators and the public. It provides access to a new and growing global society of respected scientists and journalists that are not deniers that our climate is dynamic (the only constant in nature is change) and that man plays a role in climate change through urbanization, land use changes and the introduction of greenhouse gases and aerosols, but who also believe that natural cycles such as those in the sun and oceans are also important contributors to the global changes in our climate and weather".
The blog disputes the scientific consensus on climate change that observed recent warming is very likely due primarily to human activities. The blog features the writings of:
- Joseph D'Aleo, a meteorologist
- Robert C. Balling, Jr., a professor of geography
- Sallie Baliunas, an astrophysicist
- Robert M. Carter, a paleontologist, stratigrapher and marine geologist
- and other individuals with varying levels of expertise in climatology.
In attributing recent climate change, ICECAP states that the effect of water vapor is much more significant than carbon dioxide; water vapor is a greenhouse gas, but has an expected lifetime of only ten days and makes less significant contributions to radiative forcing. On their FAQs and Myths page, ICECAP argues that limiting or reducing CO2 emissions could lead to mass extinctions, while continuing to increase emissions will protect plants and animals.
