No Doubts Global Warming
Is Real Say US Experts
12-5-3
WASHINGTON (Reuters) - There can be no doubt that global warming is
real and is being caused by people, two top U.S. government climate
experts said.
Industrial emissions are a leading cause, they say -- contradicting
critics, already in the minority, who argue that climate change could
be caused by mostly natural forces.
"There is no doubt that the composition of the atmosphere is changing
because of human activities, and today greenhouse gases are the
largest human influence on global climate," wrote Thomas Karl,
director of the National Oceanic and Atmospheric Administration's
National Climatic Data Center, and Kevin Trenberth, head of the
Climate Analysis Section at the National Center for Atmospheric
Research.
"The likely result is more frequent heat waves, droughts, extreme
precipitation events, and related impacts, e.g., wildfires, heat
stress, vegetation changes, and sea-level rise," they added in a
commentary to be published in Friday's issue of the journal Science.
Karl and Trenberth estimate that, between 1990 and 2100, there is a 90
percent probability that average global temperatures will rise by
between 3.1 and 8.9 degrees Fahrenheit (1.7 and 4.9 degrees Celsius)
because of human influences on climate.
Such dramatic warming will further melt already crumbling glaciers,
inundating coastal areas. Many other groups have already shown that
ice in Greenland, the Arctic and Antarctica is melting quickly.
Karl and Trenberth noted that carbon dioxide levels in the atmosphere
have risen by 31 percent since preindustrial times.
Carbon dioxide is the No. 1 greenhouse gas, causing warming
temperatures by trapping the Sun's energy in the atmosphere.
Emissions of sulfate and soot particles have significant effects too,
but more localized, they said.
"Given what has happened to date and is projected in the future,
significant further climate change is guaranteed," they wrote.
The United States has balked at signing international treaties to
reduce climate-changing emissions, but the two experts said global
cooperation is key.
"Climate change is truly a global issue, one that may prove to be
humanity's greatest challenge," they wrote. "It is very unlikely to be
adequately addressed without greatly improved international
cooperation and action."

Melting Ice
'Will Swamp Capitals'
By Geoffrey Lean
Environment Editor
The Independent - UK
12-6-3
Measures to fight global warming will have to be at least four times
stronger than the Kyoto Protocol if they are to avoid the melting of
the polar ice caps, inundating central London and many of the world's
biggest cities, concludes a new official report.
The report, by a German government body, says that even if it is fully
implemented, the protocol will only have a "marginal attenuating
effect" on the climate change. But last week even this was thrown into
doubt amid contradictory signals from the Russian government as to
whether it will allow the treaty to come into effect.
Global warming already kills 150,000 people a year worldwide and the
rate of climate change is soon likely to exceed anything the planet
has seen "in the last million years" says the report, produced by the
German Advisory Council on Global Change for a meeting of the world's
environment ministers to consider the future of the treaty in Milan
this week.
It concludes that the protocol must urgently be brought into force,
but only as a first step, insisting that "catastrophic" climate change
"can now only be prevented if climate protection targets are set at
substantially higher levels than those agreed internationally until
now".
The report, written by eight leading German professors, says that
"dangerous climatic changes" will become "highly probable" if the
world's average temperature is allowed to increase to more than 2
degrees centigrade above what it was before the start of the
Industrial Revolution.
Beyond that level the West Antarctic ice sheet and the Greenland ice
cap would begin gradually to melt away, eventually raising sea levels
world wide by up to 30 feet, submerging vast areas of land and key
cities worldwide. London, New York, Miami, Bombay, Calcutta, Sydney,
Shanghai, Lagos and Tokyo would be among those largely submerged by
such a rise.
Above this mark too, other "devastating" and "irreversible" changes
would be likely to take place. These include a cessation of the Indian
monsoon and the ending of the Gulf Stream, which would dramatically
worsen the climate in Britain and western Europe, even as the world
warms. Another risk is the so-called "runaway greenhouse" where rising
temperatures lead to the release of huge reservoirs methane stored in
permafrost and the oceans, adding to global warming and starting a
self-reinforcing cycle that would eventually make the earth
uninhabitable.
To avoid such catastrophe, the report says that industrialised
countries will have to cut emissions of greenhouse gases like carbon
dioxide by at least 20 per cent by 2020, and by up to 60 per cent by
2050. The Kyoto Protocol would at best cut them by 5 per cent by 2012,
and probably less, even if it were brought into force and fully
implemented.
In the meantime the world looks as if it will greatly exceed the
targets. Writing in The Independent on Sunday today, Michael Meacher,
the former environment minister, calculates that global emissions of
greenhouse gases could increase by 75 per cent by 2020, "putting the
world well on the way to doomsday".

That is really funny. There is an ICE age coming! The "Green House gases"
won't stop it! |

'Prehistoric man began global warming'
Date: December 11 2003
Measurements of ancient air bubbles trapped in Antarctic ice offers
evidence that humans have been changing the global climate since
thousands of years before the industrial revolution.
From 8000 years ago, atmospheric levels of carbon dioxide began to
rise as humans started clearing forests, planting crops and raising
livestock, a scientist said on Tuesday. Methane levels started
increasing 3000 years later.

So the fault lies with the hand full of people 8000 years ago? A few modest
tribes did all that? GMAB!
But it didn't stop the ice age from arriving on time, did it? The earth has
some significant self regulation involved, WE can only make a tiny
influence!
Before we started raising cattle ( a major source of methane) there were
herds of buffalo and before that, mammoths! There are more trees now than
when Criss crossed the pond! And measuring temperatures near major cities
will not yield accurate data. But a weather satellite view makes all areas
available!
At Raytheon Remote Sensors (the weather satellite people) some of their
scientists predict that at their location the average temperature will rise
2 degrees F in approximately 9,680 years, but only after the next ice age
ends!
Citing some "professor" with a left leaning bent is not proof nor even
credible indication. The whole drive behind the "Global warming" hoax is
anti human and political!
There are many forces that have influence on the weather, including for
instance Volcano activity. More methane than all the cattle for a year on
the planet in a day! |

Clearly an error. Except for a bit of local impact in Europe and Africa,
humans have barely had any impact up to the last 500 years or so. |
