radiative effect of CO2 has contributed, at most, only about 28% to the human-caused warming up to the present. The other 72% is still a result of human activities! Pielke has criticized the IPCC for its conclusions regarding CO2 and global warming and accused it of selectively choosing data to support a selective view of the science. In 2010 Pielke revisited a question provided by Andrew Revkin "Is most of the observed warming over the last 50 years likely to have been due to the increase in greenhouse gas concentrations", Pielke stated that "the 2010 answer ... remains NO", and that "The added greenhouse gases from human activity clearly have a role in increasing the heat content of the climate system from what it otherwise would be", but "there are other equally or even more important significant human climate forcings" and furthermore "We now know, however, that the natural variations of atmospheric and ocean circulation features within the climate system produces global average heat changes that are substantially larger than what was known in 2005. The IPCC models have failed to adequately simulate this effect." Family Pielke is married. He has two children. His son Roger A. Pielke Jr. is a political scientist and works in the field of climate policy. His daughter Tara Pielke is a web developer. Publications Pielke has published more than 300 scientific papers, 50 chapters in books, and co-edited 9 books. A listing of papers can be viewed at the Pielke Research Group website.
