I remember summers being hot for a while in the Midwest. We used to put up a shade awning on the deck. But it's been at least 5 years since we've needed it. The past few years there's been such a cool breeze from the north that I rarely eat dinner out on the deck.
The earth seems to have tilted on it's axis so that the sun is far north during the summer. More than previously. Ice core samples taken from Antarctica show the last 800,000 years ice, which scientist can tell what the climate was like in the past. They found its a cycle of ice ages lasting about 100,000 years with warming up periods between the ice ages lasting about 10,000 years. The last ice age ended about 10,000 years ago. 17 major league baseball games were cancelled today because of snow.
Yeah, I live in Portland and have no problem with the changes. But it's usually pretty mild regardless of the season, what with it basically being a coastal climate. I have a friend who lived in Phoenix for many years and jumped at the chance to come up here to get away from it. 100+ degrees by mid-spring is not a way to live. :P
