The outdoor temperature and RH data that served as input parameters to the above equations were obtained from the 1961 to 1990 Global Climate Normals produced by the National Climatic Data Center
(World Meteorological Organization 1998).
And on the website of the National Climatic Data Center
, which he directs, Karl endorses the view that global warming does indeed exist.
Daily temperature data (for 1 April through 1 September) were acquired from the Midwest climate center, while 500 hPa heights were obtained from the Missouri Climate Center and the National Climatic Data Center
(Asheville, NC) webpage archives.
In March, researchers at the National Climatic Data Center
also published alarming findings: Until the mid-1970s, the planet had been warming by one degree F per century--a rate at which most ecosystems can adapt.

By mid-March, Iowa was in the "extreme drought" category, according to the index of the National Climatic Data Center
in Asheville, North Carolina.
According to the National Oceanic and Atmospheric Administration's (NOAA) National Climatic Data Center
, the 2011-2012 winter ranked as the fourth-warmest winter season on record for the contiguous U.
The storms en masse are migrating out of the tropics," James Kossin of the National Climatic Data Center
and the University of Wisconsin as well as study lead author said.
Researchers also had daily climate data down to the county level from the National Climatic Data Center
for 2010 and 2011.
Those longer trends show the world has seen "fairly dramatic warming" since the 1960s with "a smaller rate of warming over the last decade or so," said Thomas Karl, director of NOAA's National Climatic Data Center

The warmth of 2010 is "not surprising, considering that global surface temperatures have been climbing," says Deke Arndt of NOAA's National Climatic Data Center
in Asheville, N.
The resulting temperature record closely matches others independently produced by the Met Office Hadley Centre in the United Kingdom and the National Oceanic and Atmospheric Administration's National Climatic Data Center
Jay Lawrimore of NOAA's National Climatic Data Center
in North Carolina told Reuters that while "we don't say this winter is evidence of the influence of greenhouse gases," the Intergovernmental Panel on Climate Change, with which NOAA works, has found that climate chance is happening and that the actions of humans affect that.
Cities in Wisconsin, Mississippi, Texas and Illinois all posted new record low temperatures in August, according to national Climatic Data Center
