Immenent Peril

Posted by David Keelan on Monday, June 18, 2007

Who knows what to believe?  As reported here.

What special interests drive the authors of this report:

In a densely referenced scientific paper published in the Philosophical Transactions of the Royal Society A some of the world’s leading climate researchers describe in detail why they believe that humanity can no longer afford to ignore the “gravest threat” of climate change.

Courier Mail “High Price for Load of Hot Air”

Posted by David Keelan on Monday, June 18, 2007

Another skeptic…

The full article

The salient facts are these. First, the accepted global average temperature statistics used by the Intergovernmental Panel on Climate Change show that no ground-based warming has occurred since 1998. Oddly, this eight-year-long temperature stasis has occurred despite an increase over the same period of 15 parts per million (or 4 per cent) in atmospheric CO2.

Second, lower atmosphere satellite-based temperature measurements, if corrected for non-greenhouse influences such as El Nino events and large volcanic eruptions, show little if any global warming since 1979, a period over which atmospheric CO2 has increased by 55 ppm (17 per cent).

Howard officer dies after being hit by car

Posted by David Keelan on Monday, June 18, 2007

This is terrible news….

Howard officer dies after being hit by car

Wheeler was standing in the road to flag down cars that other officers using radar flagged for a traffic infraction. Investigators believe the driver — a 24-year-old woman whose name was not released — did not see Wheeler before he was struck. Charges against the driver have not been filed.

I have witnessed police in many jurisdictions using this tactic and always thought it was extremely dangerous.  One time I was driving during rush hour on I95 between Baltimore and Howard County when a State Police officer walked into the middle of the left lane and flagged down a car.  Traffic came to a screeching halt and almost caused a serious accident.  Not only does it put drivers at risk it certainly puts the officer at risk.

I certainly hope that this practice will now stop.

Let Us Talk About Kilimanjaro

Posted by David Keelan on Monday, June 18, 2007

The authoritative “climate change” web site Real Climate has a long and extensive article on tropical glacier retreats.  You can read it here.

One of the quesitons they ask is KILIMANJARO: ICON OR RED HERRING?  They basically believe the their is a cause and effect relative to global warming and glacier retreat. 

From The Guardian Newspaper global warming scare experts

The snows of Kilimanjaro, Tanzania

The white top of Africa’s highest mountain has become an icon, instantly recognisable, but Kilimanjaro’s snows are disappearing at an alarming rate. The 5,896m (19,340ft) mountain – its name, in the local Chagga tongue, means ‘that which cannot be conquered’ – is destined to lose all its snow within a decade, meteorologists predict. The great peak, which once glowed ‘unbelievably white in the sun’ according to Hemingway, will turn an uninspiring dirty brown, a victim of global warming caused by ever-increasing amounts of carbon dioxide being pumped into the atmosphere. At present, 10,000 people a year take the hike up ‘Kili’; how the loss of the snow will affect this tourist trade is uncertain. Far more worrying is the plight of the local people, whose way of life is now under threat because of drought.

Kilimanjaro’s shrinking snow not sign of warming

If we are now convinced the Kilimanjaro is not suffering the effect of man made climate change why are we still so sure about the glaciers?  What if we find a reasonable explanation for the glacier errosion – like the ice age is over (get a sense of humor). 

If the hysterics at The Guardian, and Barabara Streisand, are convinced that Kilimanjaro is loosing it’s snow cap because of human activity and then other evidence shows the loss of the snow cap is because of solar activity then what is a simple guy like me supposed to believe?

Don’t we need to know more?

Sahara desert frontiers turn green

Posted by David Keelan on Monday, June 18, 2007

Sahara desert frontiers turn green

Satellite pictures of northern Africa show that areas lost to the Sahara desert during decades of drought are turning green again.

Analysis of images show deserts retreating in a broad band stretching from Mauritania to Eritrea, according to research in British magazine New Scientist.

The driving force behind the retreat of the deserts is believed to be increased rainfall.

Compare that to this headline:

Climate change behind Darfur killing: UN’s Ban

UN Secretary General Ban Ki-moon said that the slaughter in Darfur was triggered by global climate change and that more such conflicts may be on the horizon, in an article published Saturday. “The Darfur conflict began as an ecological crisis, arising at least in part from climate change,” Ban said in a Washington Post opinion column.

What is a person to think. Are we expected to accept that global warming real when we are constantly presented with such conflicting information and reports?

Meanwhile trying to explain the behavior of deserts is just as difficult as explaining the behavior of a teenager.  Here is an article on the formation of the Sahara desert.

Sahara desert born 4,000 years ago

Using a new computer simulation of the Earth’s climate, German scientists say that the Sahara underwent a brutal climate change about 4,000 years ago.

Over a very short time scale – possibly as short as 300 years – it went from grasslands with low shrubs to the desert we are familiar with today. Summer temperatures increased rapidly and rainfall almost ceased. The change devastated many ancient cultures and caused those that did survive to migrate elsewhere.

Scientists at the Potsdam Institute for Climate Research say that the desertification of the Sahara was one of the most dramatic changes in climate over the past 11,000 years.

The loss of agricultural land to the desert may have been one of the reasons why early civilisations developed along the valleys of the Nile, the Tigris and the Euphrates.

Feedback mechanism

Slight climate alterations caused by subtle changes in the Earth’s orbit around the Sun were amplified by a climatic feedback mechanism.

Some 9,000 years ago the tilt of the Earth’s axis was 24.14 degrees; today it is 23.45 degrees. Today, the Earth is closest to the Sun in January. Nine thousand years ago, our planet was closest to the Sun at the end of July.

The changes in the tilt of the Earth occur gradually. However, the interplay of atmosphere, ocean and landmass can react to these changes in abrupt and severe ways.

The climate model suggests that land use by man was not an important factor in the creation of the Sahara.

What is my point?  The information is contridictary and we don’t know what is going on.  Of course the researchers could be wrong.  I have not seen their models and really have no idea if and when the earth’s axis changed.  So if you have these models please share them with us.
