Unusual: not usual or common or ordinary The climate of the past 25 years is usual common and ordinary.

The graph is distorted to support the "hockey stick" theory of temperature. In fact few scientists today--even those that believe in man-made global warming--believe that the current temperatures exceed that of the Medieval Climate Optimum (which is why the are currently saying "past 400 years".) However, my point still stands; to label the current climate as "unusual" is clearly false. Even IF the MCO did not have as drastic upward temperature climb, it demonstrates that rapid change is possible. The "Little Ice Age" also points out that an even more drastic decline happened--if the temperature can go down that quickly, why can't it go up even faster? The conceit of the global warmists is that the earth is static and unchanging and that there is some sort of optimum temperature. ALL the evidence is to the contrary--over its history the temperature of the earth has changed drastically and will continue to change. One problem is statistical and quite annoying; 1977 was a very cool year. This is why 25 years has been chosen as the range of increase, rather than 30 or 20. You pick either of the latter and suddenly the temperature change isn't so drastic after all. This is scientific cherry picking at the worse. By the way, if you examine the Medieval Climate Optimum, you'll find it coincided with a peak in solar intensity. Such a peak is happening right now as well. (Temperatures at the north pole in Mars have also risen, giving more evidence to a strong solar cause of recent global warming.) (http://www.fathersforlife.org/REA/warming4.htm[^].)

It doesn't matter. The geologic evidence points to higher temperatures than exist today.

Ok, so if you can't prove it its meaningless? They can't prove that these methods for guessing what the temperature was 1000 years ago are absolutely 100% correct so its meaningless. You just typed it. They are confident, but that's not proof. And by the way, I think global warming is very real and not desirable, and that is only my opinion because we don't have absolute proof.

Good point. If you can't prove it you can't call it fact. But I'm not hung up on facts. I don't need to prove a creator's existence, I'll find out when the time comes, good enough for me, some have experience which they call fact, that's subjective. But if you can't prove those things, just like they can't prove that their confident data is fact, then it isn't fact. Its assumption, its guessing. And since you bring up quantum randomness, remember that the observed behaves according to the intent of the observer. So this data could very well be meaningless except to those who are seeking it. I would accept as fact that they measured an old tree. I would not accept as fact the inference they make based on that tree about the age in which it existed. I might trust their findings, but they aren't facts. This statement is false.

what "25 years"?
25 years is the oft quoted time frame used by proponents of man-made global warming.

it certainly does. you can't see 50-100 year changes on a graph like that, and it's doubtful the measurements used to create it have the kind of resolution needed to produce anything you can compare with the kind of records we have for the last 150 or so years.
Now you're just making a fool of yourself. You argue that the rate of change in the past x years exceeds all that in history, but then dismiss any data that is previous that the "last 150 or so years." You can't have it both ways. But it doesn't matter in geologic terms. We know that temperatures were lower during the past ice age. To believe otherwise, is to be deliberately ignorant. We know temperatures were significantly higher about 7000 years ago; hence the formation of peat bogs in northern climes. To argue that since we don't know the exact temperature, therefore the preponderance of evidence for frequent climate change must be dismissed is silly. It's also hypocritical since by point of fact, we don't have really good climate data going back more than few decades at the most.

O. M. G. i have never, ever, not once, in this thread, said anything about the "average" temperature. i'm gonna say it one last time: rate of change.
Likewise, the rate of change now is NOT unusual. The rate of change leading into and out of the Little Ice Age vastly exceeded the rate of change today which is why very few legitimate scientists even argue that point.

maybe something similar to what's happening now happened thousands of years ago. but we do not have the data to show it.
YES WE DO. Please read up on ice cores and tree ring data. Read up on fossils. NO legitimate scientist is arguing with rate of change since they would look very foolis
