Temperatures: Global temperatures have been flat since 1998
Global Cooling: 'Attention in the public debate seems to be moving away from the 15-17 year ‘pause’ to the cooling since 2002,” writes Dr. Judith Curry, the chair of the School of Earth and Atmospheric Sciences at Georgia Institute of Technology.
Extreme Weather: “It is misleading and just plain incorrect to claim that disasters associated with hurricanes, tornadoes, floods or droughts have increased on climate timescales either in the United States or globally,” Professor Roger Pielke Jr. said in his testimony before the Senate Environment and Public Works Committee.
Hurricanes: 'Hurricanes have not increased in frequency, intensity or normalized damage in the U.S. since 1900.
Tornadoes: Tornadoes and tropical cyclones have also not become more intense or frequent since 1950 and 1970, respectfully.
Floods: U.S. floods have not increased in frequency or intensity since 1950, according to Professor Roger Pielke Jr., and droughts have become shorter, less frequent, and smaller over the last century. Globally, floods have changed very little in the last 60 years.
Wildfires: Dr. Bjorn Lomborg, the “skeptical environmentalist,” writes: “Historical analysis of wildfires around the world shows that since 1950 their numbers have decreased globally by 15%… The world has not seen a general increase in drought. A study published in Nature in November shows globally that ‘there has been little change in drought over the past 60 years.’
Arctic Ice: Arctic sea ice coverage was 29 percent greater in September of this year compared to the same time last year — with ice covering 533,000 square miles of ocean more than last year.
Antarctic Ice: The south pole has also fared well, despite rising greenhouse gas emissions. Antarctic sea ice hit a 35-year record high in September — covering nearly 20 million square kilometers of ocean with ice. The previous sea ice coverage record was in 2012, meaning there have been two straight record high years.
Sea Level: National Oceanic and Atmospheric Administration data show the sea levels only rose 1.1 to 1.3 millimeters per year from 2005 to 2012. This is actually below the rate of sea level rise from 1954 to 2003.
