************************************************************
I wish to thank the House Committee on Science and Technology for the opportunity to present my views on the issue of climate change – or as it was once referred to: global warming.
The written testimony is, of course, far more detailed than my oral summary will be.
In the summary, I will simply try to clarify what the debate over climate change is really about.
It most certainly is not about whether climate is
changing: it always is.
It is not about whether CO2 is increasing: it clearly is. It is not about whether the increase in CO2, by itself, will
lead to some warming: it should.
The debate is simply over the matter of how much warming the increase in CO2 can lead to, and the connection of such warming to the innumerable claimed catastrophes.
The evidence is that the increase in CO2 will lead to very little warming, and that the connection of this minimal warming (or even significant warming) to the purported catastrophes is also minimal.
The arguments on which the catastrophic claims are made are extremely weak – and commonly acknowledged as such.
