In 1948, just before I was born, pictures were taken of our home just east of Riverside, in southern California. The snow was 4 feet deep. We had cold and cool weather in the 1950s, and in 1966 we have another round of snow ... I recall the clamor that we were entering another ice age. I can recall that we had so much rain in S. California that we would be allowed to stay home from school. The current warming trend is welcome to me.
About a 1,000 years ago the earth entered what we call the Little Ice Age. The sun's energy output lowered, and we had a rash of volcanoes go off at times, which further made the situation worse. There was a lot of suffering in Europe. The Little Ice Age was still going on up through the early beginnings of the United States. The reason I welcome the current warming trend is that 1,000 years ago and beyond, the earth was at its natural level of heat, which allowed farming of remote northern places, like Greenland by the Vikings, and other land far north which cannot be used today for food and growth.
While the earth is warming, I do not believe that it is harmful, nor do I believe that human activity is the prime cause. Recently, I heard it announced on the radio that the sun is back to its normal energy output and is shunning brighter than it has for 1,000 years ... and that this is the prime cause of global warming. Having a science and engineering background, I have not found anything which shows that human activity is a prime factor in warming trends. Former VP Al Gore stated in a speech in California that human activity caused the El Nino' effect, which brings warming weather up north, along with flooding rains instead of snow. The problem is, science discovered the El Nino' effect well over 300-years ago, before human activity accounted for much.
I strongly believe that the average person needs to do a lot more study, keep an open mind, and cool their jets with respect to the strong rhetoric being bantied about. Some of the stuff I read may as well be in a Watchtower magazine, as it is so lacking in facts, and so filled with feelings based on unproven beliefs. Humans need to understand these natural warming and cooling cycles and prepare to meet them head on and survive them, rather than moaning about big corporate conspiracies.
