How is earth hour connected to global climate change?

Answer 1

It isn't. During "Earth Hour", people are encouraged to turn off all lights and electrical devices, as some sort of symbolic gesture about the need to conserve. It accomplishes next to nothing.

"Global climate change" is a meaningless phrase concerning the paranoia about changing weather. Back in the 1970's, people feared "global cooling"; more recently, the worry was "global warming". Since neither one was happening, the new buzzphrase is "climate change".

However, "change" is what the climate DOES. There are natural climate cycles of warming and cooling; the annual cycle of winter and summer, but also 100 year cycles and 1000 year cycles, which are entirely natural in origin. In Roman days, London was a fairly warm city; then it got quite cold during the Dark Ages, when the Vikings sailed south. By the year 900, the world was warming and the Vikings went west to Greenland (because it was a "green land") and settled the coastline with dairy farms. By 1300, the temperature was falling again. In the 1700s, children were skating on the frozen canals of the Netherlands, and George Washington's army dragged cannons across the frozen Hudson river. The temperature started to warm in the early 1800s, and we're probably approaching the high point of this long cycle. We didn't cause this warming - and we won't be responsible for the cooling which will probably follow by 2050 or so.

No matter what Al "Chicken Little" Gore says, the sky is NOT falling.
