The planet has evolved mechanisms over geological time (4.5 billion years of trial and error) to protect itself. Earth’s climate varies for a lot of extraterrestrial reasons. The shortest period has to do with the interplay of solar activity and cosmic radiation from the Milky Way. During quiet periods of solar activity, like now, cosmic radiation penetrates the atmosphere and creates clouds where conditions permit. Over long periods this cools the earth. Most of the time however, sun’s magnetic activity induces earth’s geomagnetic field. The geomagnetic shields are up during most of the 11 year sun spot cycle. Earth’s cooling (1940-1965) and earth’s heating (balance of the 20th century) is 95% correlated to sunspot peak frequency. Short cycles induce cooling and long cycles induce warming. This is a magnificently balanced system because the total solar irradiance varies very little. The subtlety is the correlation with sunspot peak frequency. During the Maunder Minimum there were no sunspots and the world suffered through the Little Ice Age.

CO2 has come out of the planet during 4.5 billion years of volcanic activity. Plants use CO2 to produce carbohydrates, oxygen and water vapour. Free oxygen is not produced by volcanoes. CO2 has the property of inverse solubility. Global warming from the sun forces CO2 out of the ocean in increasing quantities like warming beer. CO2 is the effect, not the cause of the warming. Moreover, the absorption wavelength for CO2 in the spectrum is filled. CO2 will not contribute any more heating. The analogy is adding a second Venetian blind to your window may not make the room any darker.

Sea level is said to be rising (ICPP) at 2 – 3 mm a year. Since the Pleistocene it has risen 125 metres (6 mm a year) and most of the coastal tribes of the earth have a Noah. The coral reefs of the oceans have kept pace because of a symbiotic relationship with algae that keep them thriving in the sunlit surface of the sea no matter how fast sea level rises. Barrier bars like the Atlantic longshore bar are dynamic features that are fed sand by Piedmont rivers and maintain themselves in the surf zone. A summer beach is wide and fine and a winter beach is coarse and steep. Common sense needs to be applied.

By the way modern coal-fired power plants produce electricity, water vapour and CO2; plant food not pollution. The US has enough coal and oil shale to support itself for 1,000 years. This AGW piece is political, not scientific, and is coming out on party lines.

“With a well-managed mutation program and a little luck from Mother Nature, you might be able to kick-start your personal genetic development. These results won’t be perfect — you’ll have to take the adaptations you get — but on an aggressive regimen of morning irradiation and afternoon mutagen shakes, you’re sure to sprout something useful sooner or later.”

It then lists things such as photosynthetic skin (to create energy), scaly skin (to keep you moist), giant ears (to keep you cool) and a host of other useful genetic screw-ups.

Have you been drinking your mutagen shakes?
