GLOBAL WARMING MAN-MADE DISASTER OR NATURAL CHANGE?
[Sunday Telegraph-March 18-2007]
Most scientists concur that it's
getting hotter, but they can't agree
Richard Gray - Science correspondent
WITH QUESTIONS still hanging over
crucial issues around climate change, scientists are adamant about one
THE DEBATE IS FAR FROM FINISHED.
Few now dispute that the climate is
warming, but there remains a split over whether or not human beings are
THE CASE FOR MAN-KIND CLIMATE CHANGE.
According to most climate scientists,
the current period of global warming is being driven by man-made carbon
dioxide (CO2 ) emissions. A
green house gas, CO2 in the
atmosphere reflects heat given off by the Earth back to the surface. In
simple terms scientists believe human activities, such as burning fossil
fuels and deforestation have disrupted the natural balance of greenhouse
gases, causing temperatures to rise above normal levels.
Prof piers Forster, a lead author on the
Intergovernmental panel on Climate Change's (IPCC) fourth report and a
climate change researcher at the University of Leeds, admits that the
picture is complicated. However, he insists that greenhouse -gas
emissions are the only way to explain the temperature rises being
" Certainly the story is complex."
he said. "Since 1970, however, we
really start to see a big temperature rise and an increase in greenhouse
gases -it is hard to ignore."
Experts also claim that improved
understanding of the effects of other pollutants, such as aerosols, help
to explain anomalies in the data, such as a period of climate cooling
between 1940 and 1970.
They believe that soot particles and
aerosols masked the overall warming effect of carbon dioxide by
providing a protective blanket that acted like a sunscreen to reflect
the sun's rays.
BUT THEY ADMIT that there are many
questions THAT STILL NEED TO BE ANSWERED before the EARTH's climate and
the IMPACT of GLOBAL WARNING can be FULLY UNDERSTOOD.
Recent research has also focused on
natural systems that may be worsening or dampening the effects of
The role of water vapour, a greenhouse
gas, is one of the most poorly understood. Others include the effect of
the ocean's ability to absorb heat and carbon dioxide.
THE CASE AGAINST MAN-MADE GLOBAL
Scientists on the opposite side of the
argument insist that the warming of the PLANET is due to NATURAL CYCLES
that have been repeated THROUGHOUT HISTORY.
They seize upon one of the most
compelling uncertainties in the climate change
-the ROLE of the SUN.
It is widely accepted that historic ice
ages and subsequent warm periods were due to shifts in the Earth's orbit
in relation to the Sun or to the Sun's activity.
Sceptics claim that we are in a period
of high solar activity and that warming will end when that activity
falls. In the recent report by the IPCC, solar activity had the
largest error margins of all the influences on the climate.
VOLCANIC ACTIVITY IS ALSO BELIEVED TO
HAVE PLAYED A MAJOR ROLE IN HISTORIC SHIFTS.
Prof. Richard Lindzen, a prominent
climate-change sceptic and meteorologist at the Massachusetts Institute
of Technology said:
"The influence of volcanoes and
solar variability is essentially unknown. The issue is reduced to
essentially religious faith."
Another key objection of sceptics is
the apparent inability of climate -change computer models to accurately
explain the level of global warming that is occurring. Evidence from ice
and seabed cores also points to the cyclic nature
of the warming and cooling of the Earth.
Prof Bob Carter, a marine geophysicist
at James Cook University in Queensland, Australia, said:
"That climate changes frequently,
rapidly and sometimes unpredictability has been conventional knowledge
among Earth environmental scientists since the early days of ocean
drilling in the 1970s"
Prof Don Easterbrook, a geologist at
Western Washington University, believes the Earth is in the grip of a
30-year warming cycle. He said:
"Past climatic trends indicate that
global climates should begin to cool sometime between now and 2010."
[Anyone watching the programme-
Climate Change Swindle
would be aware that there were other
eminent scientists who supported the sceptic case. Obviously the
newspaper is restricted by space on either side of the question.
One point that was raised many times in
the programme was that if they could only agree with the other side of
the argument -then there would be more financial resources coming their
way in the way of grants etc.
WHAT MUST NOT HAPPEN
That the sceptic argument be ignored or
even staved of extra resources as the QUESTION of the CAUSES of GLOBAL
WARMING are much too IMPORTANT to be FULLY ANSWERED than to support one
side of an ISSUE which AFFECTS ALL MANKIND?]
