The all encompassing Climate Change/AGW Thread..

[vr94ss]

That graph just goes to show that the best prediction for the next 50 - 100 years is that temperatures are going to start to go down, and along with it CO2 levels.

You read graphs as well as you use excel it seems.. How does it predict temperatures going down? It shows temperatures follow atmospheric CO2 levels. That predicts that as we add more CO2 the atmosphere temps will continue to rise. All evidence shows this and that is why there is a scientific consensus.

Are you for real?

This is an all topic AGW thread. Seeing as this tax is coming in because of the AGW alarmists, then it is a valid question in this thread.

Cmon mate, you can have it both ways, if you want to keep agw out of the "all political thread", keep politics out of the "all agw thread".

So at the end of the interglacial period, what will happen? Are you saying the co2 will keep rising so the temp will too? If that is the case, what has caused the temp drop at the end of each interglacial period? What has caused the co2 concentration to so rapidly drop? Why is it so different this time? Why will a carbon tax fix something that has fixed itself naturally every interglacial period?

So what it temperatures rise 1 degree in 50 years... in 500 they may drop 10. It's all about cycles, everything in nature is and so it the earths CO2 levels, temp, etc... see below.

Yes, there have been cycles before as your graphs show, I assume they are accurate.

Bid did you actually pay any attention to the magnitudes on both axis. Those cycles have a period of 100,000 years. Our current man induced cycle has a graph that looks like that but its time span is 100 years. Did you also notice the actual maximum ppm of CO2, about 300ppm, but right here now in 2011 we have 392ppm. Clearly those graphs you have chosen to show are not indicative of what is happening now or either the level of co2 or the time in which it took to happen, a different forcing factor is at work here, the answer is obvious, man has released extra co2 into the atmosphere very quickly by digging up fossiled carbon and burning it

no it doesnt, for the same reasons Ive listed above.

Haha. Cows are a bigger problem for the ozone layer than we are! But I guess you could still blame us for growing so many of them :hmmm:

shouldnt politics best be in the all things political thread?

touche'

Cmon mate, you can have it both ways, if you want to keep agw out of the "all political thread", keep politics out of the "all agw thread".

We can't isolate one from the other.

I suppose it was getting a bit difficult in that postings on different topics were being mixed and we're here now so: game on.

Its one of those chicken or the egg debates. If the earth was to warm due to some other factor, a higher rate of evaporation of the oceans would occur. This releases CO2 which enters the atmosphere. The links between Temperature and CO2 are definitely valid, but debate surrounds whether the warming causes atmospheric CO2, or CO2 causes warming.

Ive read a few papers on the correlation between increased solar activity and global temperatures and it makes for some interesting reading. The general jist of it is when the sun goes through periods of increased heat output the earth warms slightly, causing CO2 levels to rise regardless of what we humans do. When Solar activity decreases the earth cools slightly the Oceans will re-absorb the CO2 again.

Im not a scientist but it does make sense to me that the sun is the dominant factor in global temperature. After all, its quite hot.......

If you like I can close this thread, ban you for multiple user names and we can all move on? Or you can discuss AGW here and everything that goes with it. Your call commsirac.

So at the end of the interglacial period, what will happen? Are you saying the co2 will keep rising so the temp will too? If that is the case, what has caused the temp drop at the end of each interglacial period? What has caused the co2 concentration to so rapidly drop? Why is it so different this time? ?

Because in the past these cycles were largely caused by what is known as milankovitch cycles: changes in the aspects of the earth's orbits caused heating and release of co2as the temp dropped co2 was reasborbed by the oceans, it was not rapid(its 20,000 years on the graph), http://www.homepage.montana.edu/~geol445/hyperglac/time1/milankov.htm,

Rapid: is how we have increased co2 from 280ppm to 392ppm in less than a hundred years!


we are not in the middle of one of these malinkovitch extremes at the moment, hence why scientists will tell you the rise of co2 and temp that the earth is experiencing now is not part of a natural cycle
