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.
