IDEOLOGICAL DEBATE ON CLIMATE CHANGE

Climate has drastically changed over the last 30 years. Weather has become erratic with drought, cyclones, tsunamis that strike nations only to strike again in quick succession.

An ideological debate has arisen among the far left and right on the nature of fossil fuels in warming the climate and the sources of power generation to come. 

Will the day come when Australia has closed all coal powered stations and suffers from massive power shortage in homes, offices, schools, hospitals, water supply and defence? Is this an act of national sabotage among the opponents of an acceptable source of power generation? Is there a hidden agenda?

It is the burning of fossil fuels that has directed global warming. The planet has been covered with a blanket of carbon dioxide that is taken in by trees, grass lands and sea grasses across the world. But more seems to gather in the atmosphere.

We see rains and snows across the world that is taken as proof that global warming does not exist. We must not forget that carbon dioxide is used to make dry ice that may cause clouds high in the atmosphere to produce ice and snow.

A recent report advised that the snows in the Australian Alps are falling at higher altitudes every year. On the Kokoda Track the nights in 1977 were freezing cold. Now in 2019, the temperature is cold but mild. Mosquitoes have moved to the top of the Owen Stanley range.

The world TV weather reports shows the sweep of the ocean currents that traverse the planet bringing rain to land and sea.

Climate change makes us forget the lessons of geography from high school studies. We learned of the winter and summer solstices, monsoons, relief rains that were lifted by mountains, orographic rains and El Nino droughts.

Some countries with a broad ocean front receive regular rains. Rain clouds come up from the Antarctic and sweep across Australia, New Zealand and the Pacific. 

There are two major currents in the Northern and Southern Pacific that sweep around from Asia to America one clock-wise and the other anti-clockwise above and below the equator.

Currents carry rain to Africa and Western Europe but with little rain across the deserts of the Middle East.

Two weeks ago there was a report about India running out of water. Village wells were running dry. This week we see reports of people from India wading through water waist deep.

Australia can benefit from the rains from the Antarctic. Monsoons fill the northern rivers and promote a laissez faire attitude in Government to building dams for towns and farms in central Australia.

The United States suffers from the cold winds that blow across the continent to collide with the warm winds of the Gulf Stream. When the winds blow in circular motion, there is a hurricane on the way.

But we can not escape the reality that the burning of fossil fuels is the key to global warming. The billions of daily cooking fires in China and India are major causes of carbon dioxide emissions. Will the totalitarian Middle Kingdom destroy the planet until the end comes? China and India will die too.

Australia claims to be selling Adani coal that is clean. Does this mean it is free from carbon dioxide? Is this coal without toxic exhaust fumes? That is a strange phenomenon.

Nations are moving towards nuclear power with a decision by the Australian Government being postponed at all times. What happens when we have no power generation to keep the nation going 24/7 ?
