SSDD,
Your graph doesn't show me anything I don't already know. On another graph it shows that global temperatures have been on a slight downswing since the Permain-Triassic period. This cooling really started to take off at about the mid Tertiary period. This no doubt had something to do with the breakup of the contenents. But though there has been generalized cooling, I wouldn't call it an "ice age." It just happens to be the type of place our planet happens to be in for the time being.
The fact that ice exists at both poles indicates that the earth is presently in an ice age whether you would call it an ice age or not. Google the term "present ice age" and you will get plenty of credible sources stating that the earth is in an ice age...we are experiencing an interglacial period at present but the ice age is not over and won't be for a good long time yet...the fact is that the earth is coming out of an ice age and as you can see by the graph of earth temperature history I provided, the temperature has a good long way to climb before the ice age ends....the fact that the temperature increases as the earth exits an ice age should come as no surprise to anyone..
You then ask me what would cause me to think that a warming isn't expected. Well first of all, right now it looks like CO2 is going up at a faster rate than it has ever done. That is without an asteroid strike or the massive and long lasting eruption of the Siberian traps. And where CO2 goes, temperatures are sure to follow. And as I pointed out to someone who showed me one graph, it appeared that in the past, CO2 followed temperatures. These days, it is CO2 leading the way. That can't be good.
You are making a lot of assumptions there...the first one is that CO2 has anything at all to do with climate other than the fact that it is a gas that follows temperature around...ice cores show us clearly that CO2 follows temperature...it doesn't lead...and paper after paper keep coming out finding ever smaller climate sensitivity to CO2 vs the IPCC and climate science propaganda....eventually, the climate sensitivity to CO2 will be found very close to zero....the only effect CO2 has on climate is its contribution to the actual weight of the atmosphere. As I pointed out...relative to earth history, the present 400ppm of CO2 is abnormally low....The average CO2 concentration on earth is in excess of 1000ppm and as the ice age drags on to its inevitable end, the same thing is going to happen again....CO2 will reach normal levels regardless of what we want.
Also as to what global warming could be expected, it is unlikely that things are naturally going to change much until something drastic happens to the positions of the contenents. Another point concerns something I was telling someone else around here. To get a true idea of what is going on, we need to go to a parallel universe and find an earth exactly like ours without humans. But as far as I'm concerned, doing something like that isn't necessary to grasp what is now going on.
Visit the paleomap project...there are some interesting maps of previous climate and the position of the continents...drastic climate shifts don't depend nearly as much on land movement around the globe as you seem to think.
For example, 14 million years ago, the land masses looked like this:
Not much has changed since then... note there was no ice at the north pole and little if any at the south...Coastlines were different due to the fact that there was much more water in the oceans due to less ice.
The land masses have not moved much since that time..and yet, here is what the earth looked like 18K years ago during the last glacial maximum.
Ocean currents would have still been running much as they are today and yet, antarctic ice was almost to south american...and ice sheets extended down south of the great lakes and covered much of europe. The land masses have shifted almost none since that time and this is what the earth looks like now..
Clearly there has been a major shift in climate since the last glacial maximum but the land masses haven't moved appreciably. If you go back into history, you see further evidence that drastic changes in climate happened without drastic land movement.
This is what the earth looked like during the late Carboniferous period...100 million years ago. During that time, extensive rain forests covered most of pangea which had northern and southern deserts...Ice covered the south pole.
The Permian period, 5 million years later didn't see much change in land position, ocean currents certainly wouldn't have altered in any drastic way and yet, the ice had extended from the south and most of the southern hemisphere was covered...the tropical rain forests started turning into coal at this time....by the end of the Permian period, again, not much land movement, the ice had melted from the south pole, the tropical rain forests had been replaced with temperate forests and much of the desert had greened...it was during this time that an ice cap began to form over the north pole...
So you see, climate can change drastically with or without appreciable land movement...human beings have seen that since our time on earth began...we have moved from glacial period to interglacial with practically no land movement...the only real differences humans have experienced has been due to melting ice which was not due to land movement.
You know what all this boils down to is what I said in my thread, "A Freedom of Speech Test." Which is that most people don't really care what happens. As long as it happens to someone else. I will say to you again what I have said to others. It's better to be safe than sorry. Or let me put it another way. It is not better to be sorry than safe. I don't care what happens to our economic system as it now stands. We must change things for many reasons. Human caused global warming just happens to be the most important reason for change.
Better safe than sorry is a terrible way to look at things....if you look at history, more often people have ended up being sorry that they tried to be safe. Acting on an imagined unknown opens the door wide for unintended consequences and human beings have seen plenty of them. If hard evidence existed that CO2 was changing the climate rather than the weak corroboratory evidence, data tampering, and complete rejection of the scientific method, I would be on board...I am not because there just isn't any evidence that anything at all is happening in the climate that is even approaching the limits of natural variability.
