A Global Warming Primer


If you haven’t read the Global Warming Primer yet, you should.  It is an excellent, high-level discussion regarding global warming and many of its pertinent issues. You won’t be over-inundated with a lot of technical jargon.

There is also a blog associated with the Primer, and after you read my posts every day, you may want to read those posts.

It?s natural for non-scientists to become overwhelmed by the shouting and contradictions. It?s easy to bury your head in the sand with thoughts of, ?I like warm weather anyway?.

Controversy does exist; this is natural for such a complex science. Science evolves; it is, and should be, open to debate. The debate in climatology is leading to a consensus that tells a tale of a world already experiencing the first signals of global warming.

The greenhouse effect is a naturally occurring phenomenon of Earth?s environment, and is essential to the climate on Earth as we know it. With the natural greenhouse effect the average temperature on Earth is 15 degrees Celsius (59 degrees Fahrenheit). Without it, the average temperature would be about minus 18 degrees Celsius (or 0 degrees Fahrenheit).

Around 1750, the concentration of CO2 in the atmosphere was about 275 parts per million. Today, the concentration is 350 parts per million, or a 30% increase, and rising. Since the last half of the twentieth century, the rate of this increase has risen sharply.

As we have seen, climatology is a complex endeavor. We surely cannot know all there is to know in the workings of our planet. But the growing body of evidence would suggest that prudence and caution are called for.

These are only a few samples, you should go to the site and read the entire Primer.
