The argument that tries to belittle the current warming by pointing that in the past there have been times when it was warmer, does not have any value.

Besides the fact that a much lower temperature than in the past can do a lot of damage to the present-day beings that are not adapted to such temperatures, those higher temperatures from the past had been stable for long periods.

Now, when such a higher temperature from the past will be reached, there is no guarantee that the warming will stop there.

The greatest danger of the current warming is that, if we do not do anything about it, nobody can currently predict with any certainty that it would stop at a still acceptable temperature, matching a temperature from the distant past, instead of continuing towards even higher temperatures.
