Climate: Fighting change might prove difficult

For the past few weeks, the news has been dominated by the climate change summit in Europe. Big changes are expected to come about as a result of international agreements made at the summit.

While it may be true that global temperatures are rising, that habitat for certain species is declining, and that our concern over intensified weather events and expanding deserts is valid, it is not at all certain that humans have the ability to change any of that. The history of the Earth clearly indicates that our climate has gone through a number of warming and cooling cycles.

An example of this in “recent” history may be observed through archeological research in Greenland. Vikings settled parts of Greenland in the 10th century. They carried out extensive farming and ranching activities until a cooling climate (Little Ice Age) drove them out about 1400. Recently the climate has appeared to be returning to a warmer condition.

Humans may think they know what is best for the planet and attempt to control the climate, but there is no assurance that they will succeed or even that it would be good if we were successful.
