The scientists who study climate are convinced that this warming is man-made. There are a few who disagree, but the vast majority are in agreement. They can use computers to build climate models that can tell them what a one third increase in CO2 will do. And don't be fooled. This is just the beginning. We are actually increasing our output of CO2.
We melted the North Pole in 50 short years for Christ's sake! |
So we should build public policy on something that can't be proven or disproven.
Well....
The average temperature of the Earth has varied within a range of
about 3°C during the past 3,000 years. It is currently increasing as the
Earth recovers from a period that is known as the Little Ice Age, as
shown in Figure 1. George Washington and his army were at Valley
Forge during the coldest era in 1,500 years, but even then the temperature
was only about 1° Centigrade below the 3,000-year average.
The most recent part of this warming period is reflected by shortening
of world glaciers, as shown in Figure 2. Glaciers regularly
lengthen and shorten in delayed correlation with cooling and warming
trends. Shortening lags temperature by about 20 years, so the cur -
rent warming trend began in about 1800.
