"Looking at the Vostok ice core data, I don't see anything particularly unusal about the present temperatures. Care to point out any major differences?"When you look at the ice core data, you see cycles of warming and cooling, which is in agreement with other data. At the end, you see the temperature AND the CO2 concentrations rising to near but not at recoprd levels. But the vostok data doesn't give fine resolution on what has occurred in the last 100+ years. When you look at the already established record for the current era, it shoots past all the temprature and CO2 data contained in the vostok ice core data. In other words, the ice core is great for long term data trends, but doesn't give us the fine data for the current time. What it does show clearly is that we've reached a point today that is above what has occurred in the last 400,000 years. And you wonder why so many scientists are alarmed?
