The Dog Ate my Data

This blog is a about Anthropogenic Global Warming(AGW) which is global warming caused by the activities of man. The core issues are:

- Is the climate warming,
- Is the warming outside of historic norms
- Is it caused by anthropogenic CO2
- Will it result in global disaster as the IPCC insists

Only the first has been satisfactorily answered in part and the qualification is that the data upon which the IPCC claims are based has not been made available for full scrutiny as yet. The average terrestrial land temperature experienced slight warming this century. In some regions such as Antarctica it has cooled. The earth has been recovering from the Little Ice Age since 1650 (see Akasofu 2007 & 2009) which is one reason this warming trend is expected. It appears that this is not outside of historic norms (see Medieval Warm Period) and that the IPCC and some scientists have attempted to downplay the Medieval Warm Period and the effects of the Little Ice Age. The later two issues are not settled despite UN and government spin towards the contrary. For some excellent background from a real climatologist not implicated in the recent CRU revelations see the links to Dr Roy Spencer's blog below who discusses these issues as a professional.
