David Bellamy refutes global warming

Article in the Daily Express by David Bellamy OBE Feb 3 2005.
I first heard about global warming in the eighties and right from the
start i didn't believe in it. I teach botany. i have researched and taught
plant anatomy, ecological physiology and the history of vegetation
at universities over a period of five decades. I know that carbon
dioxide is not a terrible gas,It is the most important fertiliser for
plants. if there is more CO2 plants grow faster and tack in more.
that achieves a balance in the atmosphere. in fact most plants could
do with more CO2.
If you have time to read the expert reports in the massive tomes,
which lack an index, produced by the IPCC the intergovernmental
panel on climate change you will have a surprise. there is no proof
that anything terrible is linked to carbon induced temperature rise.

The claims about "global warming" aren't based on any scientific evaluation of the data.

A recent NASA news release confirmed something I had long suspected about the way climatologists determine average or mean temperatures.

To determine if the Earth is warming or cooling, scientists look at average temperatures. To get an "average" temperature, scientists take the warmest and the coolest temperatures in a day, and calculate the temperature that is exactly in the middle of those high and low values. This provides an average temperature for a day. These average temperatures are then calculated for spots all over the Earth, over an entire year.

This approach would be the equivalent of trying to determine the "average" age of residents in a community by looking only at the ages of its youngest and oldest residents.

Any determination of average temperature should use temperatures taken no more than 10 minutes apart to insure adequate representation of the temperatures during the day. The high temperature might reflect a temperature that only existed for a few minutes while the low temperature was present for several hours or vice versa. Chinook winds along the eastern Rockies can raise air temperatures 20 F or more within minutes. Strong cold fronts can drop temperatures just as rapidly.

More accurate comparisons should probably involve comparing the areas under the curve for different periods with the temperature measured in degrees Kelvin.

Accurately determining the heat content of the atmosphere would require calculating the amount of heat energy held by the various components of the atmosphere. Gases other than water vapor can probably treated the same because of similar coefficients of heat. However, water vapor contains substantially more heat than the rest of the atmosphere. Its coefficient of heat is a high 1.0. Plus water vapor contains 540 calories of heat per gram that must be released before it can condense to a liquid form and another 80 calories per gram to freeze. Water is normally a liquid or solid at atmospheric temperatures.
