If you are going to use science to argue religion, you have to have hard data.
The skeptics need to create a basic data table to refute the MMGW crowd. Each data set must have a source reference from a major scientific organization or journal. It must also be organized to include the various measurement standards and conversion factors, such and Gigatons and Pentagrams (roughly equivalent).
The table should start with total CO2 in the atmosphere, about 800 Gigatons.
Then it should have amount of natural CO2 sourced annually, and amount of natural CO2 sunk annually. With a breakdown of major sources and sinks.
Then it should have amount of man made CO2 sourced annually, and amount of man made CO2 sunk annually. With a breakdown of major sources and sinks.
Then, the cumulative amount of post-industrialism man made CO2 in the atmosphere, as a percentage of the total (determined by isotopic differences between natural and man made CO2). And association with what is believed to be the increase in atmospheric concentrations in that time (now said to be about 100ppm).
Much of the data used to support MMGW is both dated and cherry-picked. Therefore, disproving their theories needs current data in both a distilled and raw form.
The data list should have a list of the greenhouse *factors* (to include things like cloud cover and soot, not just gases and water vapor), and the greenhouse gases percentage of influence within them. And man made all greenhouse gases percentage of that percentage.
Then it should have a list of the greenhouse gases, broken down by gas type and its individual percentage of influence among the gases, both natural and man made. And man made CO2’s percentage of that.
Finally, it needs to include and quantify external factors influencing planetary warming, such as cosmic radiation and solar intensity.
Creating such a data table will aid immeasurably in refuting the MMGW crowd. And the sources will be cross examined, so need to be available online.
Good intentions. IMHO however, you cannot use science to defeat or even correct political science, which is similar to religious philosophy. Political science is a belief system ruled by consensus. As Professor Carter stated, the number 1 rule of the AGW Religion when confronted with science that is incompatible with one of its tenets or underlying philosophies, is to Never discuss the science. Attack the man - Repeat the mantra.
The way I look at the situation is this, solar scientists are predicting severe cooling. Past historic trends suggest massive cooling should occur sometime in the near future. We have an advantage. It is like playing headsup Texas Holdem Poker and you know you have the best hand possible, while your opponent has no clue and is betting blindly. Use this tremendous advantage. If the cooling trend occurs, warming human habitats will be big business. Outer temperate areas might turn arctic. Outer tropical areas might turn temperate. Sea levels will fall. The AGW warming crowd is going to be on the wrong side of every issue. We own the future. Use the advantage. Spread liberty. Improve the conditions of the worlds poor, potential warming be damned. Help them get cheap power and clean water.
