and one more point- there has been massive vegetation die offs- all around the globe- all through history-
Startign back with medieval times, when Greenland was producing vegetables because of mild climates back then- the ice ages hit, and there is massive die off of vegetation, then Africa it is said was once lush tropical lands- obviously we had massive veggie die off- more recently we have massive deforestations around the globe, man is clearing land all over, we had the dust bowl (not just I n this country, but others as well) where massive veggie die off occurred
You have massive wildfires all around the globe because the climate has wamred, and vegetation dries out making it a tinder bundle, you have massive amoutns of volcanos all around globe causing massive veggie die off, droughts, natural disasters, floods etc-
[[to include an explanation of how the venting started in earnest in 1950 and has been rising steadily in a steady curve:]]
No it wouldn’t- CO2 was higher than it is today, and went from low 100’s to higher 100’s rapidly caused by many different causes-
The following page shows that natural forcing’s far outweigh anything man is capable of, and likely are the causes of increases in CO2 (remember, the ‘man-caused climate changers’ love pointing out that as the earth warms, natural disasters will increase I intensity and numbers)- So as the earth was warming, naturally, it was causing more natural events to take place, causing more vegetation die off, causing further CO2 to be released, and causing the ocean sinks to release more CO2 into atmosphere many decades later as earth warmed further-

Earth has not warmed in over 20 years. Legitimate scientists are predicting MUCH COLDER WEATHER this winter; and we’re already having snow in Colorado.
The data they’re using to say the globe is warming is faulty .. because it’s BASED ON FAULTY DATA. A computer model is just that .. a model. It has been configured on false data.
Christopher Horner wrote several books on this subject and explained how it was a hoax in, “Red Hot Lies”.
If people really want to know the truth — it’s available; Christopher Horner is just one such book of truth.
What they are saying is volcanoes affect weather and weather controls climate. The sun also famously affects weather. I do not disagree with any go that and I have stressed all along that the prevailing weather controls the climate over the long run (weather is climate over the long run).
Some examples of that: Greenland used to be further south and had a lot less ice. Back then the climate was much warmer. The Isthmus of Panama was open, water and heat flowed from the Pacific into the Atlantic and the world as a whole was warmer. The closing of the isthmus was a fairly recent change. Antarctica is cut off from the rest of the world's weather and is exceptionally cold but that was not always the case.
All of those things are reasons we are in an ice age right now. We are not in full glaciation but an ice age nonetheless. Certain triggers such as increasing Antarctic sea ice can potentially bring us back into a full ice age.
None of those factors have anything to do with CO2. They are all geological. They are the opposite of the things you mention in that they all decrease temperature and thereby cause decreases in CO2. We were until recently in a CO2-starved mode. The C4 grasses developed as a result:
"The Earth has been in this `CO2-starved' mode, where C4 monocots make up a signi¢cant fraction of the Earth's total biomass, for some 7 Ma, a condition rarely (if ever) attained in the earlier history of the Earth's atmosphere"
C4 plants are Maize (corn), sorghum, pearl millet and sugarcane. Again this points out why CO2 is dropping. The factors you mention: decreased vegetation, fires, etc will increase CO2. But the natural factors mainly point to decreased CO2. Also the factors you mention like ocean sinks releasing CO2 can only release relatively small amounts. For example it takes 1 degree of warming to raise CO2 by 5-10 ppm at most. But we have 120ppm more CO2 and 2-3ppm rise per year. Obviously that cannot be from ocean warming because the ocean is not warming that much.
It also cannot be from decreases in vegetation because vegetation is not decreasing that much, see http://www.researchgate.net/.../0c9605375f15693d01000000.pdf
As for your "No it wouldn’t- CO2 was higher than it is today, and went from low 100’s to higher 100’s rapidly caused by many different causes" that is true, but that was mainly from full ice ages to interglacial and those changes took thousands of years.
