Climate change a cyclical pattern
Dear editor: The following is a mix of conjecture and reality.
A ball of molten lava upon cooling became planet earth. As the hot planet radiated heat to space the earth formed a thin crust and formed an 1,800-mile-thick mantle. Oil well drillers have found the earth temperature at 100 feet to be about 60 F
Eventually 70 per cent of the earth’s surface was covered in colossal amounts of water. It is not known from whence earth’s water originated. Likely billions of years ago space was heavily laden with water.
The hydrogen oxygen clouds and the composition of earth’s atmosphere is 78 per cent nitrogen, 21 per cent oxygen, 0.9 per cent argon and trace gasses making up the other 0.1 per cent. This small number includes carbon dioxide at 1 per cent of 0.1 per cent total trace gases.
In addition to space water retention, the earth now retains massive amounts of water. It is estimated Lake Superior alone has enough water to cover North America with one foot-plus of water. As in the past, our planet has cooling and warming cycles.
Strong solar wavelength radiation heats exposed objects including earth and water surfaces. Solar wavelength heating is similar to micro wavelength cooking ovens. The radiation agitates the food and liquid molecules. Boiling water allows us to witness molecular agitation. Alternatively the earth's long wavelength radiates heat to space.
The recent Mali volcano, like many other volcanoes, spewed tremendous amounts of gasses and ashes without causing permanent environmental degradation. Likewise forest fires, fossil fuel burning have no obvious degradation effects.
Our planet does not have abnormal accumulated amounts of heat trapping gases. Bruce Alton McGillis Penticton
For the period covering Aug. 1 through October 31, 50 per cent of cases were completed within 27 weeks. Ninety per cent of cases were complete in 55 weeks.
My Christmas present, knee replacement surgery on Dec. 22, 2018, works out to 56 weeks on the waitlist. My mother would be proud I achieved by falling in the 90th percentile!
Personally the 50th percentile, or lower, would have made me physically and psychologically happier. Karen Hutchinson
