Changes

Akasofu asserts that at least some of the contribution to global [[climate change]] comes from the natural effect of "recovery from the [[Little Ice Age]]," rather than from human activity. <ref>[http://people.iarc.uaf.edu/~sakasofu/climate.php "Response to Readers: Notes on Climate Change"], April 2007.</ref> He has criticized the [[Intergovernmental Panel on Climate Change]] (IPCC), asserting that they have failed to show "definite scientific proof that 'most' of the present warming is caused by the greenhouse effect," as the IPCC's 2007 report states. <ref>[http://people.iarc.uaf.edu/~sakasofu/misleading.php "Misleading Information on Global Warming"], IARC website, accessed February 2009.</ref> He does admit that global warming is occurring, especially in the Arctic, and that this climate change "consists of both natural change and the greenhouse effect." <ref>[http://www.iarc.uaf.edu/news/news_shorts/akasofu_4_26_06/written_testimony.php "TESTIMONY OF DR. SYUN-ICHI AKASOFU BEFORE THE UNITED STATES SENATE COMMITTEE ON COMMERCE, SCIENCE, AND TRANSPORTATION SUBCOMMITTEE ON GLOBAL CLIMATE CHANGE AND IMPACTS HEARING ON THE PROJECTED AND PAST EFFECTS OF CLIMATE CHANGE: A FOCUS ON MARINE AND TERRESTRIAL SYSTEMS"], IARC website, April 2006.</ref> His critics respond that the [[Little Ice Age ]] is somewhat of a climate change myth. The warming after the so-called [[Little Ice Age ]] "may reflect both an increase in solar activity and a redistribution of heat around the planet. In particular, " but the increase in global temperature in the first half of the 20th century may have been largely due to an increase in solar activity. The "continued warming in recent decades, however, cannot be explained by increases in solar radiation alone." <ref> [http://www.newscientist.com/article/dn11645 "Climate Myths"] New Scientists Online, accessed March 2009. </ref>
