Weather data collected from ships at sea have been called into question as
ships usually monitored the temperature of the water, not air
temperatures. Scientists assumed that seawater temperatures had a direct
correlation with air temperatures and used the data on water temperatures to
support their theories on global warming.
Subsequently, however, data collected from stationery buoys show that sea
temperatures and air temperatures do not directly correspond to one
another. This error in reasoning has lead to a nearly 40 percent
over-estimate of global warming. Satellite data have also failed to show
any significant warming trends.
