The hallmark of good science is the testing of a plausible hypothesis that is then either supported or rejected by the evidence.

Changes in solar activity have influenced what has been called the "conveyor-belt" circulation of the great Atlantic Ocean currents over the past 240 years.

I am a scientist. I go where the facts take me.

There is no experimental data that exists that supports the view that the Earth's climate is changing in any dangerous way.

Changes in clouds and rainfall can overwhelm what little effect CO2-water vapour has on temperature.

I don't like to claim that I am an expert on anything, but I have enough knowledge about climate science and climate system to be able to write scientific papers and go to meetings and talk about monsoon systems and talk about any other things that you want to discuss about climate science issues. I'm as qualified as anybody that you know on this planet on this topic.
