The latest independent analysis of world climate data by acclaimed skeptic blogger ‘Chiefio’ (aka E. M. Smith) and his blog contributors confirm that the Global Historical Climatology Network (GHCN) has cynically dumped the world’s second oldest and reliable climate record at Prague in the Czech Republic for no scientific reason.
Climate skeptics claim the censoring of the Czech’s raw data has been perpetrated by climate scientists because the Prague records prove there has been no warming in Europe for over two hundred years.
Bloggers found that GHCN, based at Arizona State University, also cut out Prague’s warm 1940’s as it would make recent warming look unexceptional. This process of adjusting raw data by climatologists (almost always upwards) is known as ‘homogenization.’ Skeptics then found that climatologists had replaced the original Prague dataset from 1949 with a homogenized warmer series from another weather station in Praha/Ruzyne even though Prague had never stopped taking temperature readings.
In other words, when the global warming alarmists found data they didn’t like, they switched it with data they did like, and figured the rubes would never notice.
