Uncle Al,

Your Wildfire math doesn't show the whole story.

"Fire can countermand certain greenhouse effects, and may, in the future, be a thermostat for global climate. If free-burning fires release greenhouse gases, they also deposit elemental carbon as a residue. The biota recapture the gases, while the carbon persists, in partial compensation for the exhumation of ancient hydrocarbons burned as fossil fuels. Proper burning in forest and shrubland can improve long-term productivity and net carbon storage. Aerosols and sulphur emissions reflect incident radiation, thus enhancing cooling. Fire effluents often serve as nuclei for clouds, further altering the radiation balance."


And from the 'United Nations Environment Programme - World Meteorological Organization'

This is how they see greenhouse gases added to atmosphere as a result of human activity:

CO2 RELEASE

"Carbon dioxide is produced when coal, oil, and natural gas (fossil fuels) are burned to produce energy used for transportation, manufacturing, heating, cooling, electricity generation, and other applications. The use of fossil fuel currently accounts for 80 to 85% of the carbon dioxide being added to the atmosphere."

(I presume the 80-85% figure is a result of their understanding that wildfires probably produce no net CO2 increase over a period).

LAND USE CHANGES

"Land use changes, e.g., clearing land for logging, ranching, and agriculture, also lead to carbon dioxide emissions. Vegetation contains carbon that is released as carbon dioxide when the vegetation decays or burns. Normally, lost vegetation would be replaced by re-growth with little or no net emission of carbon dioxide. However, over the past several hundred years, deforestation and other land use changes in many countries have contributed substantially to atmospheric carbon dioxide increases. Although deforestation is still occurring in some parts of the northern hemisphere, on the whole, re-growth of vegetation in the north appears to be taking some carbon dioxide out of the atmosphere. Most of the net carbon dioxide emissions from deforestation are currently occurring in tropical regions. Land use changes are responsible for 15 to 20% of current carbon dioxide emissions."

METHANE

"Methane (natural gas) is the second most important of the greenhouse gases resulting from human activities. It is produced by rice cultivation, cattle and sheep ranching, and by decaying material in landfills. Methane is also emitted during coal mining and oil drilling, and by leaky gas pipelines. Human activities have increased the concentration of methane in the atmosphere by about 145% above what would be present naturally."

(And if human activity has caused this current warming cycle then we can add all of the Clathrates that are being released from permafrosts etc.)

NITROUS OXIDE

"Nitrous oxide is produced by various agricultural and industrial practices. Human activities have increased the concentration of nitrous oxide in the atmosphere by about 15% above what would be present naturally."

CHLOROFLUOROCARBONS

"Chlorofluorocarbons (CFCs) have been used in refrigeration, air conditioning, and as solvents. However, the production of these gases is being eliminated under existing international agreements because they deplete the stratospheric ozone layer. Other fluorocarbons that are also greenhouse gases are being used as substitutes for CFCs in some applications, for example in refrigeration and air conditioning. Although currently very small, their contributions to climate change are expected to rise."

OZONE

"Ozone in the troposphere, that is, in the lower part of the atmosphere, is another important greenhouse gas resulting from industrial activities. It is created naturally and also by reactions in the atmosphere involving gases resulting from human activities, including nitrogen oxides from motor vehicles and power plants. Based on current data, tropospheric ozone is an important contributor to the enhanced greenhouse effect. However, in part because ozone is also produced naturally, and because of its relatively short atmospheric lifetime, the magnitude of this contribution is uncertain."

----------------------------------------------------------------

The only thing left for the Flat Earthers - oops I meant 'Anti Human Induced Global Warming Advocates' to show is that none of the above extra greenhouse gases are actually behaving like greenhouse gases.

Maybe if RicS can show us how all of the scientists should be analysing their data he might be able to demonstrate that the greenhouse gases are actually cooling the planet.
