[asa] "Intellectually honest" scientist on Global Warming

 Janice quoted Wallace Broecker: You cherry-pick and quote the
arrogant "scientists" who attempt to BS the uninitiated into
swallowing the lie that "consensus" = "science", and I'll cherry-pick
the intellectually honest, humble ones, to quote:

Since Janice considers Broecker an intellectually honest scientist, it
is helpful and even educational to explore the position of this
scientist

In 1975 Broecker published a paper

Broecker, Wallace S. Climatic Change: Are We on the Brink of a
Pronounced Global Warming? Science, Volume 189, Issue 4201, pp.
460-463

If man-made dust is unimportant as a major cause of climatic change,
then a strong case can be made that the present cooling trend will,
within a decade or so, give way to a pronounced warming induced by
carbon dioxide. By analogy with similar events in the past, the
natural climatic cooling which, since 1940, has more than compensated
for the carbon dioxide effect, will soon bottom out. Once this
happens, the exponential rise in the atmospheric carbon dioxide
content will tend to become a significant factor and by early in the
next century will have driven the mean planetary temperature beyond
the limits experienced during the last 1000 years.</quote>

A powerful prediction indeed.

Broecker also proposed the conveyor belt hypothesis which transports
warm water from the pacific equitorial regions via the Indian and
Southern Atlantic ocean to the northern reachers of the Greenland
Iceland Norwegian Basin.

He argues that small changes in forcing can lead to large and abrupt
changes in climate and weather patterns, strengthening the need to
reduce human forcings.

Broecker argues that
<quote>The ongoing accumulation of heat-trapping industrial gases
blanketing the Earth threatens to raise global temperatures, he said,
but such a rise would occur gradually. Far more worrisome is the
buildup's potential to stress the climate system past a crucial
threshold that would disrupt the Conveyor and set off a rapid
reconfiguration of Earth's climate, predicted by existing computer
models.</quote>

Broecker underlines the urgency

<quote>"Action on global warming cannot be delayed," said Wallace S
Broecker, a professor at Columbia University who is joining Iceland
scientists in the study.</quote>

Surely these wise words from this "intellectually honest and humble"
scientist should raise a certain level of concern in Janice?

In Christ
