Topic: Temperature Data

The Climatic Research Unit (CRU) at the University of East Anglia is reported to have lost or destroyed the original raw data used for global temperature records. In response to Freedom of Information requests, the unit claimed it only possesses "homogenized" or manipulated data because it lacked storage resources in the 1980s. The hosts highlight this as a major blow to the credibility of the scientific consensus on warming.

The Royal Dutch Meteorological Institute (KNMI) is accused of manipulating historical temperature data to make modern heat waves appear more frequent. Critics point out that the institute lowered temperature readings from 100 years ago by two degrees Celsius, effectively changing the baseline for what constitutes a heat wave. The hosts discuss the historical accuracy of mercury thermometers compared to modern electronic sensors.

The National Oceanic and Atmospheric Administration (NOAA) reported July 2012 as the hottest month on record, but critics argue the data is flawed due to the placement of sensors near asphalt and changes in equipment paint. Additionally, heavy rains are being used by insurance companies as a justification to increase premiums.

The UK Met Office announced a plan to re-examine 160 years of temperature data following the "Climategate" email leak, which damaged public confidence in man-made global warming science. British Prime Minister Gordon Brown is criticized for comparing climate change skeptics to "flat earthers," arguing the analogy is historically reversed.
