This is a contentious topic. No doubt. Here’s the truth all scientists agree on: Earth gets warmer and colder, goes in and out of Ice Ages. Even Ice Ages have warming trends. We are in a warming trend in the most recent Ice Age. Eventually (not in our life time), Earth will pass out of the warming trend, back to the coolness of a frigid Ice Age.
What people don’t agree on is why. What causes Global warming and Global cooling? Is it changes in the tilt of the planet on its access? Or our revolution around the Sun? CO2 gases? Man?
Another fact we know is that the press likes hyperbole and drama, so when fear of Global Cooling ends, fear of Global Warming begins. It sells books, newspapers, speeches.
I don’t have an answer. I’m simply an observer. Read this and let me know what you think.
The number of Americans who believe there is solid evidence that the Earth is warming because of pollution is at its lowest point in three years, according to a survey.
The poll of 1,500 adults by the Pew Research Center for the People & the Press found that only 57 per cent believe there is strong scientific evidence that the Earth has become warmer over the past few decades, and as a result, people are viewing the problem as less serious – down from 77 per cent in 2006.
The steepest drop occurred during the last year, as Congress and the Obama administration have taken steps to control heat-trapping emissions for the first time. The drop also was seen during a time of mounting scientific evidence of climate change – from melting ice caps to the world’s oceans hitting the highest monthly recorded temperatures this summer.
