Art Horn is a meteorologist and runs a website called the “Art” of Weather .
Stance on Climate Change
“At times the temperature has gone up and at times it has gone down. Even with carbon dioxide levels increasing there has been no rise in global temperature for 10 years.” 
“A very important component of our future energy development direction and production will come not necessarily from the truth but what is perceived to be the truth. Make no mistake, what today’s young people are being taught in school about energy and its relationship to global warming will determine what direction we go in developing the critical energy resources we need.” 
On Horn's website, he advertises his weather program for high school students titled “Understanding Global Warming .” If you invite Horn to your school, he will demonstrate “clearly with vivid graphics how computer model forecasts are not able to predict the climate 50 to 100 years in the future.”
His PowerPoint presentations explain how “long term changes in solar activity have a strong relationship to global temperature,” how “the earth is now in it's eighth year of global cooling” and why “changes in the sun and the oceans are causing this.”
Horn believes his programs are vital in educating students to make the right decisions on political issues:
“Today's students will soon be tomorrow's voters and they will need to know the science, not the politics of this major issue to make educated choices. My program will give them that.”
Horn also hosts  another program, “How the Weather Works,” in elementary and middle schools where he has recently added a section on global warming “towards the end.”
Not all schools received Horn's global warming presentations favorably, however. He has received complaints from parents, and a principal once called his presentation “very one sided.” Out of 160 schools Horn proposed his program to, “only two responded favourably.” 
March 2 - 4, 2008
Horn attended  the Heartland Institute's 2008 International Conference on Climate Change and signed the subsequent Manhattan Declaration on Climate Change. 
The Manhattan Declaration  declares that “'Global warming' is not a global crisis,” and 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.”
The Declaration argues that adaptation is “massively more cost-effective than any attempted mitigation,” asks world leaders to reject the views of the IPCC, and demands that “all taxes, regulations, and other interventions intended to reduce emissions of CO2 be abandoned forthwith.”
Co-sponsors for the 2008 International Conference on Climate Change included prominent climate change denial groups (many funded by the oil industry) including the Committee For a Constructive Tomorrow (CFACT ), the Competitive Enterprise Institute (CEI ), the Frontiers of Freedom Institute , The International Climate Science Coalition (ICSC ), the George C. Marshall Institute , the Science and Environmental Policy Project (SEPP ), The Science and Public Policy Institute (SPPI ) and numerous others.
2007 - Ongoing
Horn provides public presentations where he argues that global warming is a myth. According to a 2007 Hartford Advocate news  article, “Horn has been giving the presentation Global Warming: Fact or Fiction, since last fall, at libraries and other public meeting places throughout Connecticut, Massachusetts and Florida.” 
Art Horn hosts a one-hour long PowerPoint presentation titled “Global Warming Exposed! ” where he says “I will expose the myths and the lies of those who say carbon dioxide is a dangerous pollutant. You will see how changes in the sun and ocean temperatures have ruled the climate in the past and continue to do so today.”
