Viewpoint: Get off warming bandwagon
Currents BBC
Changes in ocean currents may cause global warning
By Professor William M Gray of Colorado State University
As a boy, I remember seeing articles about the large global warming that 
had taken place between 1900 and 1945. No one understood or knew if this 
warming would continue. Then the warming abated and I heard little about 
such warming through the late 1940s and into the 1970s.

In fact, surface measurements showed a small global cooling between the 
mid-1940s and the early 1970s. During the 1970s, there was speculation 
concerning an increase in this cooling. Some speculated that a new ice 
age may not be far off.

Then in the 1980s, it all changed again. The current global warming 
bandwagon that US-European governments have been alarming us with is 
still in full swing.

Not our fault

Are we, the fossil-fuel-burning public, partially responsible for this 
recent warming trend? Almost assuredly not.

These small global temperature increases of the last 25 years and over 
the last century are likely natural changes that the globe has seen many 
times in the past.


Human kind has little or nothing to do with the recent temperature changes

This small warming is likely a result of the natural alterations in 
global ocean currents which are driven by ocean salinity variations. 
Ocean circulation variations are as yet little understood.

Human kind has little or nothing to do with the recent temperature 
changes. We are not that influential.

There is a negative or complementary nature to human-induced greenhouse 
gas increases in comparison with the dominant natural greenhouse gas of 
water vapour and its cloud derivatives.

It has been assumed by the human-induced global warming advocates that 
as anthropogenic greenhouse gases increase that water vapour and 
upper-level cloudiness will also rise and lead to accelerated warming - 
a positive feedback loop.

It is not the human-induced greenhouse gases themselves which cause 
significant warming but the assumed extra water vapour and cloudiness 
that some scientists hypothesise.

Negative feedback

The global general circulation models which simulate significant amounts 
of human-induced warming are incorrectly structured to give this 
positive feedback loop.

Their internal model assumptions are thus not realistic.


As human-induced greenhouse gases rise, global-averaged upper-level 
atmospheric water vapour and thin cirrus should be expected to decrease 
not increase.

Water vapour and cirrus cloudiness should be thought of as a negative 
rather than a positive feedback to human-induced - or anthropogenic 
greenhouse gas increases.

No significant human-induced greenhouse gas warming can occur with such 
a negative feedback loop.

Climate debate has 'life of its own'

Our global climate's temperature has always fluctuated back and forth 
and it will continue to do so, irrespective of how much or how little 
greenhouse gases we put into the atmosphere.

Although initially generated by honest scientific questions of how 
human-produced greenhouse gases might affect global climate, this topic 
has now taken on a life of its own.

It has been extended and grossly exaggerated and misused by those 
wishing to make gain from the exploitation of ignorance on this subject.

This includes the governments of developed countries, the media and 
scientists who are willing to bend their objectivity to obtain 
government grants for research on this topic.

I have closely followed the carbon dioxide warming arguments. From what 
I have learned of how the atmosphere ticks over 40 years of study, I 
have been unable to convince myself that a doubling of human-induced 
greenhouse gases can lead to anything but quite small and insignificant 
amounts of global warming.
