Christopher Landsea, formerly a research meteorologist with Hurricane Research Division of Atlantic Oceanographic & Meteorological Laboratory at NOAA, is now the Science and Operations Officer at the National Hurricane Center. Meteorology (from Greek grc μετέωρος metéōros, "high in the sky" and grc -λογία -logia) is the Interdisciplinary The National Oceanic and Atmospheric Administration ( NOAA) is a scientific agency within the United States Department of Commerce focused on the conditions of the The US National Hurricane Center, located at Florida International University in Miami Florida, is the division of National Weather Service He is a member of the American Geophysical Union and the American Meteorological Society. The American Geophysical Union (or AGU) is a nonprofit organization of Geophysicists consisting of over 50000 members from over 135 countries The American Meteorological Society ( AMS) promotes the development and dissemination of information and education on the atmospheric and related oceanic He earned his doctoral degree in Atmospheric Science at Colorado State University. Colorado State University is a public institution of higher learning located in Fort Collins, Colorado in the United States. Over the years, his work has involved the general hurricane FAQ currently on the National Hurricane Center website and the Atlantic hurricane reanalysis. Atlantic hurricane reanalysis is an ongoing project within the National Oceanic and Atmospheric Administration which seeks to correct and add new information about past He has been focal on the link between global warming and hurricane intensity change. Global warming is the increase in the average measured temperature of the
Landsea has published a number of research papers on cyclones and hurricanes. In Meteorology, a cyclone refers to an area of closed circular fluid motion rotating in the same direction as the Earth. A tropical cyclone is a storm system characterized by a low pressure center and numerous Thunderstorms that produce strong winds and Flooding He is the author of Hurricanes, Typhoons, and Tropical Cyclones: FAQ.  He also has been the lead scientist in the Atlantic hurricane reanalysis since 1997. Atlantic hurricane reanalysis is an ongoing project within the National Oceanic and Atmospheric Administration which seeks to correct and add new information about past Year 1997 ( MCMXCVII) was a Common year starting on Wednesday (link will display full 1997 Gregorian calendar
In January, 2005, Landsea withdrew from his participation in the IPCC Fourth Assessment Report. Climate Change 2007, the Fourth Assessment Report (AR4 of the United Nations Intergovernmental Panel on Climate Change ( IPCC) is the fourth Landsea claimed the IPCC had become politicized and the leadership ignored his concerns.  Landsea does not believe that global warming has a strong influence on hurricanes: "global warming might be enhancing hurricane winds, but only by 1 percent or 2 percent". Global warming is the increase in the average measured temperature of the He strongly questions the accuracy of the historical global hurricane database for comparisons with current observations, citing an uncounted, catastrophic 1970 storm as an example.  According to agency emails gathered by Salon and later released by Rep. Saloncom, part of Salon Media Group ( often just called Salon, is an online Henry Waxman, Republican administrators chose Landsea over another scientist in the NOAA to speak to the media about the link between hurricanes and climate change after Hurricane Katrina devastated New Orleans. Henry Arnold Waxman (born September 12, 1939 in Los Angeles California) is an American politician. Hurricane Katrina of the 2005 Atlantic hurricane season was the costliest hurricane, as well as one of the five deadliest in the history of the United States New Orleans (nʲuːˈɔrliənz nʲuːˈɔrlənz French: La Nouvelle-Orléans) is a major United States port city and the largest city in Louisiana 
In an interview on PBS, Christopher Landsea said "we certainly see substantial warming in the ocean and atmosphere over the last several decades on the order of a degree Fahrenheit, and I have no doubt a portion of that, at least, is due to greenhouse warming. The question is whether we're seeing any real increases in the hurricane activity. " He went on to say "with the Atlantic hurricanes in particular, they're due to changes both in the ocean as well as the atmosphere. Just changing the ocean where it's a little bit warmer isn't sufficient. " As for climate change affecting hurricane strength, Landsea said that global warming theories and numerical modeling suggest only that "hurricanes like Katrina and Rita may have been stronger due to global warming but maybe by one or two miles per hour. "
Roger A. Pielke (Jr), who originally published Landsea's letter, expressed his opinion that the actual IPCC report "maintain[s] consistency with the actual balance of opinion(s) in the community of relevant experts. " Regarding IPCC politics, Pielke suggested that anyone who fails to see that the IPCC talks had political elements "isn't paying attention. "
