there was only one question and you answered it.

if one looks over the temperature charts from the past back to when they first started making them,there is a pattern.
every hundred years or so there is a 10 year period of higher and lower than normal temperatures.after these 10 years,the temperature levels out.

I read somewhere we were at the end of those 10 years,so wouldnt that mean that in your time the temperatures would be not as extreme?

also,what exactly is IT?
