Simple-Simon question stumps the Warmists

There is a site here which claims to have all the answers to "climate denier" arguments

But there is one question that was put to them 3 days ago now that they still have not even attempted to answer. It is a question perfectly well-grounded in fact but pushes them right off their mental tramtracks. The question reads as follows:

Hey guys!

I gather that the global temperature has risen by less than one degree Celsius in the last 150 years

That sounds to me like we live in an era of exceptional climate stability

What am I missing?
