Certainly we are in the midst of Global Warming
The current reports do remind one of Chicken Little and the sky is falling. A report that we will have to canoe to the Legislative Building in Victoria, British Columbia, we shall have to swim to our bus stop, what garbage. The facts remain that we are in a period of warming.

Certainly we are in the midst of Global Warming
The current reports do remind one of Chicken Little and the sky is falling. A report that we will have to canoe to the Legislative Building in Victoria, British Columbia, we shall have to swim to our bus stop, what garbage. The facts remain that we are in a period of warming.
The Milankovitch cycle apparently shows there is a period of about 100,000 years. It does appear that there are three basic cycles that we must endure. The earth does cycle around the sun there is a high eccentricity and a low eccentricity from a more elliptical to a more circular orbit. This period is about 400,000 and 100,000 years.
The earth as it charges about the sun is on an axis that tilts variable from 24.5 degrees to 21.5 degrees thus the effect of the suns rays vary substantially. This period is about 41,000 years. We now add to this the wobble of the earth with a period of 23,000 years. These three variables in total should have a far greater influence on our life than many of our feeble efforts.
A look at our small spot in the Universe as it hurdles through space, (expanding?) at the equator moving at 1,000 miles per hour endlessly. One must consider that there is probably one molecule in the very center that does not move. We have tides that slosh about on definite cycles relative to the moon. There are reports that the tides are also measurable on earth by rising and falling as in the oceans.
Krakatoa blew its top in 1883 and the climate was altered for years, about 35,000 people died and 300 towns destroyed. Vesuvius did in 79 AD destroy Pompeii (today a tourist spot), Mount St Helens blew 1200 feet from the mountain. In about 1500 BC Thera probably wiped out a lot of early European civilization.
It is reported that there are great under ice rivers in Antarctica with a fear that they could break out from under the ice. Do not forget that there is volcanic action on the continent. The water flows are reported to be greater than the Thames (must be a UK report)
The point being that we cannot control most of the great tragedies in the world. Global warming is one. Look at World War 2 we put more carbon dioxide into the air than one could proper calculate and we survived.
The greatest pollution problem we face today is people. We have seen the population in a lifetime go from 4 billion to a currently reported 6.5 billion and climbing. Canada from under 8 million during WW1 to well over 30 million today. These people need to eat sleep, be heated and transported about. We must halt the virtually uncontrolled growth of population. The World Health people have done a great job relative to infant death, and extending the life, we must control the growth as Malthus warned. Healthy people will enjoy sex but they will reproduce.
What has caused the magnetic north pole to take a fast scamper towards Russia?
No I will not get a canoe if I chose to visit Victoria, British Columbia.
