Things I get in my email:
Hey troops;
As long as we're at it, let's go to www.accuweather.com, and get back into this issue of Global Climate Change. These guys have the statistics backed by ACTUAL records, showing that we are actually cooling. Let's see where they are wrong.

There is a story, possibly true, that if you put a frog in a pan of water on the stove and gradually heat up the water till it is boiling, the frog will just sit there and let himself be cooked. This seems a little unlikely to me, but it is a well known story. Either way, if you put a lid on the pan the temperature in the pan will go higher than if there is no lid. (In the water it will only go to 212F, but above the water the trapped steam will be a lot hotter than no trapped steam.)
For our purposes, you are a frog in a large, very complex, pan heated by the sun. And the pan is moving so nothing is constant at any one point. When it is heating up in the north it is cooling in the south, to name the most obvious of the variability factors. Happens every year. Up, down, lots of clouds over Montana, cooler there. Drought and no clouds over western Australia, warmer there. Lots of local variability.
On your particular pan there is a partially one way, mostly transparent, lid called The Atmosphere. Some heat does escape back out thru this special lid; the chemical composition of the gasses in The Atmosphere determines the percentage that escapes. This is pretty basic science and does not seem controversial to me. CO2 is one of the main gasses that determines how fast the heat escapes, there are others as well, but CO2 appears to be the main one.
Weather is interesting and looking backward from, say 10,000 years in the future, weather statistics will have painted a meaningful picture. But local weather statistics, for the less than 100 years of their existence, are almost meaningless. Interesting, but not much good for extrapolating the future. Feel free to learn what you need to know about statistics and science to become your own weather and climate expert. As for me, I have other things to do, but I can understand what the vast majority of weather experts have said, and that is that temperatures are rising and are destined to rise even faster.
Global warming is about the lid on the pan, not local weather variability. CO2 has been building up at an ever increasing rate all during the industrial age as we burned carbon at an ever increasing rate.
Weather variability does make it very difficult to prove that the atmosphere is heating up. What is not difficult is to see that glaciers are disappearing around the world and the polar ice caps are getting smaller. Is it the cooler weather that is doing it? Must be if we are actually cooling.
And it has also been shown conclusively that CO2 in the atmosphere has been building at an ever increasing rate. I do not find it difficult to understand that changing the atmosphere will result in changed weather. What is so hard about that?
Inconvenient as global warming is, I think we should do whatever is necessary to minimize the carbon buildup that is the source of the problem.
