NASA making the earth warm through data manipulation?

NASA is now manipulating the data so that it complies with radical global warming theories. With James Hansen running the show I would not believe the revisions that NASA is now reporting. When their temperature data conflicts with the scientific data of others I certainly would not believe NASA. Frankly, when you consider the accuracy of the instruments, the recordings and the measuring station differences from 1889 until now a one degree change is about meaningless. The only reason these people are freaking is because of melting ice, rising CO2 levels and believing bad computer models. These models cannot even model past climate yet future. Higher CO2 levels historically did not mean lower earth temperatures and the ice melt may have nothing to do with overall warming of the earth. It may have more to do with natural cycles and changes in micro climates.

Does ‘climate change’ mean ‘changing data’?

NASA is not the only source of long-term temperature data used to evaluate climate change. Like NASA, the UK Meteorological Office’s Hadley Center for Climate Studies depends on a network of ground-based weather stations using thermometers. Both are limited by their number of stations, the heat-island effects on many of the sites located in urban areas, changes in thermometer types over time and the loss of station sites over the historical periods being measured. Data gathered from these systems often has to be adjusted to remove “noise” caused by the local environment so it can be standardized for analysis.

The University of Alabama at Huntsville and Remote Sensing Systems provide data gathered by Earth-observation satellites. Satellite temperature data has the advantage of being gathered across the entire surface of the Earth, except for regions near the two poles, but it is unavailable for the period prior to 1978.

How do these other data sources compare to NASA?

According to Hadley’s data, worldwide temperatures have declined since 1998 and the Earth is not much warmer now than it was than it was in 1878 or 1941.

Both the UAH and RSS satellite data agree with Hadley and show temperatures declining over the past decade with only a slight increase above the 30-year average between 1978 and 2008.

More recently, NASA temperatures indicated March 2008 was the third-warmest March in history. RSS and UAH showed the same month as only slightly above average globally and the second-coldest ever in the southern hemisphere.

As WND has previously reported James Hansen, head of NASA’s Goddard Institute for Space Studies, warned in 2006 “we have a very brief window of opportunity to deal with climate change … no longer than a decade, at the most” – the same week the National Oceanic and Atmospheric Administration issued a report saying the U.S.’s hottest year was in the past, 1936.
