Okay... The baseline in different and the time span has greatly expanded - the so-called Medieval Warm Period doesn't disappear, but it does get put into a bigger context, so it looks less dramatic. Also, maybe it was warm in Europe, but not on other places around the globe? That's what new data does sometimes.
The overall pattern is not in question. The physics of the situation are accepted by virtually everyone. Carbon dioxide is now rising for a different reason that it has risen in the past.
We are currently at 395ppm which is higher than in the past 15 Million years. And the temperature is rising faster than in a very long time.
The next decade or two are the most important time for humankind. Are we gonna' go into the dustbin of time with a whimper, or are we going to try to do what we think is best, based on our best understanding of reality?
