Lets Remember where we live. We live on the third planet from a medium-size sun. Our planet is 5 Billion years old, and it has been changing constantly all during this time. The is Earth is now on its third atmosphere.
The first atmosphere was helium and hydrogen. It dissipated early n, because the planet was so hot. Then, as the planet cooled, there were volcanic eruptions produced in the second atmosphere of steam and carbon dioxide. Later the water vapour condensed, forming the oceans that cover most of the planet. Then around three million years ago, some bacteria evolved to consume carbon dioxide and excrete a highly toxic gas, oxygen. Other bacteria released nitrogen. The atmospheric concentration of these gases slowly increased. Organisms that could not adapt died out.
Meanwhile the planet’s land masses, floating on huge tectonic plates, eventually came together in a configuration that inferred with the circulation of ocean currents. It began to get cold for the first time. The first ice appeared two billion years ago.
And for the last seven hundred thousand years, our planet has been in a geological ice age, characterised by advancing and retreating glacial ice. No one is entirely sure why, but ice now covers the planet every hundred thousand years, with smaller advances every twenty thousand or so. The last advance was twenty thousand years ago, so we’re due for the next one.
And even today, after five billion years, our planet remains amazingly active. We have five hundred volcanoes, and an eruption every two weeks. Earthquakes are continuous: a million and half a year, a moderate Richter 5 quake every six hours, a big earthquake every ten days. Tsunamis race across the
Our atmosphere is as violent as the land beneath it. At any moment there are one thousand five hundred electrical storms across the planet. Eleven lightening bolts strike the ground every second. A tornado teas across the surface every six hours. And every four days, a giant cyclonic storm, hundreds of miles in diameter, spins over the ocean and wreaks havoc on the land.
The nasty little apes that call themselves human beings can do nothing except run and hide. For these same apes to imagine they can stabilise this atmosphere is arrogant beyond belief. They cant control the climate.
The reality is, they run from the storms.
Conclusion:
- We know astonishingly little about every aspect of the environment, from its past history to its present state, to how to conserve and protect it.
- Natural warming trend began in the year 1850, as we emerged from a 400- year cold spell known as the “Little Ice Age”
- Nobody knows how much of the present warming trend might be a natural phenomenon.
- Nobody knows how much of the present warming trend might be man- made.
- Nobody know how much warming will occur in the next century.
We cant ‘assess’ the future, nor can we ‘predict’ it. These are euphemisms. We can only guess. An informed guess is just a guess.
