This letter is to those extremely few people who have decided that they know more than a fifth grader. (It was a TV show about first to fifth grade questions.)

When I “go shopping” with my wife, I usually stay in the vehicle reading or talking on my flip-phone. Most days I end up rolling down the windows to cool off. Even a fifth grader knows that the sun’s rays come into the vehicle’s cabin and warms the seats and trim. The air gets hot because the sun’s rays can come through the glass but the heat rays can’t go back out.

Why? In the nineteenth century, a physicist discovered that extremely minute amount of carbon dioxide will block infra-red heat rays from escaping a confined area. We live in a confined area called Earth.

Earth is surrounded by an atmosphere with a very small amount of carbon dioxide. For life to survive on this planet we need a tiny amount. Just a few parts in a million less means Joliet is under thousands of feet of ice or a few more gives us Venus’ atmosphere. Glacial ice in Greenland indicates the air in 1744 had 277 parts per million. That period was before the industrial age started. The amount in 2017 was 407 ppm. Major volcanic activity can have a temporary cooling period such as the Little Ice Age but as CO₂ has increased so has the temperature.

Now almost every year is hotter than the previous one, the world’s glaciers and ice caps are melting, oceans are expanding from heat, and the world is changing fast. For a week last winter Antarctica was warmer than Disney World!

Even fools can realize the truth by wading coastal cities’ streets during king tides each month. It is stupid and foolish to deny facts you can see.
