I have doubts about AGW not because I borrowed other people's opinions but instead I went to an original data source - the Global Historical Climatology Network - and plotted the raw (version 2) temperature data, both for different countries and also as a global average. The results show that there are a range of trends going on. Some, like that for Sri Lanka, are clearly related to geothermal activity. Temperatures for Countries such as the UK and Germany have neither increased nor decreased significantly over the last 150 years, and Canada, Russia (Asian sector) and China have been getting colder. I know from examining the raw data that the global temperature graphs typically shown in the media contain significant distortions, which are due to missing temperature data within the series for particular locations. For example, Turkey only has reliable temperatures for the last 50 years or so, and when you add patchy series into the global average it appears to increase or decrease suddenly. If I only plot temperature series which are more than 98% complete over the last 150 years the overall trend looks like a very linear increase in temperature of around 1-2 degrees. It certainly not obvious that there is a significant anthropogenic component.
