On Climate Change/Global Warming
When all this 'chatter' is going on about the pros and cons of Human impact on our biosphere, let's remember where we live. We live on the third planet from a medium sized sun. Our planet is 5 billion years old, and it has been changing constantly all that time. The Earth is on its 3rd atmosphere.
The 1st was helium and hydrogen, but that lasted only a short time early on, as the planet was so hot. Then as the planet cooled, volcanic eruptions created a 2nd atmosphere of steam and carbon dioxide. Time passed and the water vapour condensed, forming the oceans, that cover most of the planet. About 3 billion years ago, bacteria evolved to consume CO2 and excrete highly toxic Oxygen and Nitrogen. Concentration of these gases slowly increased and organisms that could not adapt, died out.
Meanwhile, the land masses, floating on tectonic plates, eventually came together in a configuration that interfered with the circulation of ocean currents, and the temperature began to get cold for the first time. The first ice appeared about 2 billion years ago.
For the last seven hundred thousand years, our planet has been in a geological ice age, characterized by advancing and retreating glacial ice cycles. No one knows why, but ice now covers the earth every hundred thousand years, with smaller advances every 20 thousand years or so. The last advance was about 20 thousand years ago, so we are due for another one.
Even today, after 5 billion years, our planet remains highly active, and we have 500 volcanoes, and an eruption every 2 weeks. Earthquakes are continuous: a million and a half every year, a moderate level 5 every 6 hours, a big quake every 10 days. Tsunamis race across the Pacific Ocean every 3 months.
Our atmosphere is as violent as the land beneath it. At any moment there are 1500 electrical storms across the planet, 11 lightning bolts hit the ground each second, and a tornado tears across the surface every 6 hours. And every 4 days, a giant cyclonic storm, hundreds of miles in diameter, spins over the ocean and wrecks 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 stabilize this atmosphere is arrogant beyond belief. They can't control the climate.
The reality is, they run from storms.
