The OP is a straw man.
Let's talk about the following:
During the 1000's to 1300's wine grapes in Europe grew 300 miles further north than they do today. Present wineries in Southern England are only 40 years old. A thriving wine industry existed until the last winery in England closed in 1317. It appears it was warmer during this period. Why was that?
There was also a warm period during the expansion of the Roman Empire.
There was also the Holocene High, as I recall 4000-7000 years ago. It was much warmer then. Why was that?
For about 90% of the time from the Cambrian to today the average Earth's temperature was 72 degrees F. It is presently about 58 degrees F.
Do you think we are warmer or colder than NORMAL?
Please compare the amount of CO2 emitted by man vs. its natural occurrence.
Please compare the CO2 today to all times past, to at least the Cambrian. Looks to me like the only other time CO2 was this low was during the glaciations during the Pennsylvanian
What is the biggest green house gas? (If you answer anything but H2O, you are a liar). So I have seen anything from 93%(EPA) to 97% of the green house gas effect attributed to H2O. Why is it you don't mention this? Don't you want to talk about something you can't do anything about?
Is global warming bad? Evidence shows people, animals and plants all do better if the average temperature is higher. Deserts shrink, agricultural production goes up, and in short everyone does better. Why are you against that?
If our CO2 production has kept us from returning to the last ice age, which I doubt, it's man's greatest accomplishment. In case you didn't notice, living during an ice age sucks.
Is there a plot? No! But I could point out that there is no money to be made by saying there is no problem. Problems need funding, non-problems do not.
Would you agree with that?
In case you missed it
1.) Explain why it was warmer in the past.
2.) Show that man's contribution of CO2 has been significant today in regards to TOTAL green house warming (that would include H2O) vs. the natural occurrence.
3.) Show that a warmer average temperature (say back to the Cambrian) is BAD.
