Quote of the Week: “It is one thing to impose drastic measures and harsh economic penalties when an environmental problem is clear-cut and severe. It is quite another to do so when the environmental problem is largely hypothetical and not substantiated by careful observations. This is definitely the case with global warming.” – Frederick Seitz, Introduction to Fred Singer’s Hot Talk, Cold Science (1999)

NO TWTW NEXT WEEK: There will be no TWTW the week of September 26. TWTW will resume the weekend of October 3.
Greenhouse Effect – Critical for Life: Last week, TWTW discussed that in 1859, physicist John Tyndall began experiments on gases that interfere with the loss of electromagnetic energy (heat) from the surface of the earth to space. These gases, known as greenhouse gases, keep the earth warmer than it would be otherwise, particularly at night. Tyndall recognized that water vapor is the dominant greenhouse gas, and without it land masses would freeze at night, making vegetative growth virtually impossible.
