I'm not sure we have enough information to make a really informed

going
through considering its apparent age.

From my time on this planet, heat waves during the summer are
normal.
Don't see how global warming will affect that. It'll be 90 one week
and
100 the next, that's just movement of the jet stream. If the jet
stream
shifts to bring air down from Canada, it'll cool down again.

Core samples have documented a thermal foot print that goes back
several hundred years.

The last 10 years have shown a continuing increase in annual
temperatures.
