I agree. After adding all the uncertainties of the proxy data and our models (which we use to calculate temperature throughout Earth's history) it's not that sure change like this has never happened before, or that it is happening faster than ever before. There's no doubt we have impact, but it's not certain that it's the major driving force (though it may be, of course). Earth has several effects which periodically changes the climate. Those effects can coincide.
At least that's what paleobiologist on a lecture I visited said. His appeal was: hold on to strict facts and take uncertainties into account. Don't hop on the doomsday wagon. We simply don't know enough about complexities of the climate.
