The average temperature today is six or seven tenths of a degree Celsius (about 1.2 degree Fahrenheit) warmer than it was a hundred years ago. Now admittedly, some years the average goes down, and some areas of the earth have actually cooled during that time, but overall, the earth is a bit warmer than it used to be.
So, is this a problem? If so, is it caused by man and his pollutants, or is it just a natural trend that will probably reverse itself over the next hundred years? What do you think?
And why am I sitting here writing when I should be preparing for houseguests? Well, now, there’s another good question. My son read about global warming this morning in his science lesson, and I got curious, so I did a bit of research. Anybody have any thoughts on it?
