Climate science is not verifiable

Professor P.D.Jones has said that "He will not divulge the data on
which he bases his conclusions about climate because Skeptics might
seek to prove him wrong".
To me this is tantamount to saying that he has little confidence that
the data sup****ts his conclusions
Added to this is the fact that his colleague D.E. Parker has yet( after
25years) to publish the reasons why he modified the crude Sea Surface
Temperatures (which show that the SSTs in1870s were as high as those in
the 1970s)  to yield those presently accepted.
These two are Britain's leading climatologists and their conclusions
have influenced the GW  debate fundamentally.Because of their attitude,
we have been unable to verify their conclusions which have been treated
by other climatologists and environmentalists as infallible.
This is not the way true science should work
