westwall,Both of these points are factually incorrect. The rate of CO2 increase is far less than seen in Phanerozoic era. That Era saw a truly massive and rapid increase as a result of the earth warming and foliage growth.
The Phanerozoic is the current era, running from 549 MYA up to the present. I have been told by half a dozen deniers that the chronological resolution of proxy data of just 11,700 years of the Holocene Epoch was inadequate to support the contention that the rate of current CO2 and temperature increases were unprecedented. Yet now you claim to be able to identify higher rates in events hundreds of millions of years ago. Neat trick.
Within the last 65 million years, the most dramatic CO2 event was the Azolla event. This was a rapid reduction of CO2 which is given credit for the appearance of the Earth's iced poles. The event produced an 80% reduction in CO2 (3500 to 650 ppm) over a period of 800,000 years. The current event has produced a 43% increase (280 to 400 ppm) in 150 years.
Let's do the math: 3500 - 650 = 2850 ppm
2850 ppm / 800,000 = 0.00356 ppm / year
vs
120 ppm / 150 years = 0.8 ppm / year
So the current rate of change is 224 TIMES as fast as the fastest prior event in the last 65 million years
Lets do history. History says every claim you have made that increased temperatures will cause...didn't. Game, set, match.
The debate between Crick and Billy_Bob aside, I have to say again that we could possibly be facing changes that have never happened before. Is it really worth the risk? Also, there are graphs that say all types of things. But Billy_Bob showed one that charted both temperatures and CO2 levels. Across the whole chart, temperatures led the way. But these days, CO2 is leading the way. That's something different. On another chart I was looking at it showed that methane release was also going up. Which as you probably know is an even worse greenhouse gas. I don't think we can yet call this dangerous game.
Why? What is different now than back then? The Earth is physically no different now than when it was significantly warmer. Even in the period of time where we have written history it has been far warmer. Not one catastrophe that the progressive socialists claim will happen, ever did. Furthermore, the historical record shows that CO2 rise follows temperature rise so the hysteria about CO2 is just that....hysteria not borne out by fact. Methane is the newest gas to try and panic the savages, but anyone with a brain can look back eight thousand years ago to the Holocene Thermal Maximum and see that even when temps were 5 degrees centigrade warmer than today NOTHING happened.
Well, not nothing. Life prospered. That much is very clear. Life likes it warm. ALL life.
