Piers Corbyn says: "Prof Joanna Haigh, head of Physics of Imperial College and a leading Bishop of the CO2 warmistas religion, has made misleading statememts in the Telegraph (link below) which are easily refutable by any student in Imperial College Physics1.

One might find it curious (but I don't) that she finds the time to attack a politician for seeking a more open approach on the issue yet was unable to find the time to walk 100 yards to actually debate by invitation the matters at our WeatherAction - Climate Realists conference which included international speakers by video links and was attended by the BBC, in Imperial College October 2009 (the first Climate Fools Day event).

In The Telegraph she misleadingly implies Boris Johnson believes in a direct correspondence between solar activity amounts and London weather and then says he should be wary of drawing such conclusions - which he has never drawn. [There is of course a complex yet predictable relationship between modulated solar activity and weather patterns]. She knows and Telegraph readers (whom she takes for stupid) know that Boris made it clear he cannot comment on science details but has seen WeatherAction forecasts, which he receives on a regular basis, succeed again and again and again and is simply saying WeatherAction should be listened to, especially because of the economic implications of any coming mini ice age.

WeatherAction being listened to is the Co2 warmistas great fear because it would bring in a new age of enlightenment of evidence-based science and poltics and would end the corruption of science expressed by the stranglehold of CO2 warmistas on UK schools and academia from year one in Primary schools to the Royal Society (a door upon which Prof Haigh is knocking).

She claims Greenhouse gases are driving world warming and "We dont need to invoke mysterious solar particles to understand long term trends". As any student in IC Physics1 (and I along with Brian May was such in 1965) will point out her CO2 claims are negated by observational fact and it is only solar activity including magnetic sun-earth connection that can explain the ~22yr - the strongest of all - variation in world temperatures and other climate parameters. Further the longer term observed correlation between smoothed solar activity and world temperatures is well known and has never been refuted.

I challenge Joanna Haigh to:

1. Produce observational evidence with real observed data (or accepted proxies thereof) from the last hundreds, thousands or million years that CO2 changes in the real atmosphere drive world temperature changes.

2. Produce observational evidence and physics-based argument that refute our knowledge that the ~22yr cycle of variation in World temperatures is driven by the ~22yr magnetic ('Hale') cycle of the Sun
