We are worried about carbon-dioxide emissions poisoning our ozone which would lead to catastrophic events like ultra-violet and cosmic radiations slicing through us like butter. We think that the ozone being ether, it can only be de-stabilized by a gas. We forget that we are protected from the fatal cosmic radiations and ultra-violet rays by a carefully evolved carbon system.
Carbon dioxide doesn't affect Ozone. CFCs (Chloroflouocarbons) affect ozone. The way ozone helps is that it absorbs UV light, keeping (damaging) UV rays away from the earth, thus protecting humans. Carbon dioxide is a greenhouse gas, i.e. causes more infrared radiation ("heat") to stay trapped in the atmosphere, warming the earth.
The carbon system on our planet has evolved over billions of years to a stable state that has ways of re-asserting balance.
Plant life, which covers almost every inch of land has played a major role in absorbing un-imaginable amounts of carbon from the atmosphere and combined them with other elements to store them in solid forms that are not released to the atmosphere in millions of years.
Trillions upon trillions of marine organisms also collect carbon from the atmosphere and trap it in their shells and as they die and fall to the bottom of the oceans, they are packed into limestone by the pressure.
The plants and organisms thrive on high levels of carbon in the atmosphere and release oxygen and nitrogen into the atmosphere. This alone, reduces the carbon levels in the atmosphere by 76%.
True, but mankind has been adding on a lot of extra Carbon dioxide to the CO2 cycles, this is causing the CO2 cycle to destabilise. Before industrialisation the CO2 cycles were in equilibrium, but now we are releasing extra CO2, therefore getting an increase in CO2 concentration in the atmosphere, again leading to more warming.
The weather, which is basically the amount of water in the atmosphere, is controlled by our oceans. The water surface, which makes up most of the total earth’s surface, is responsible for the distribution of temperatures on earth plays an important role in keeping the balance that the carbon system needs. The ‘weather’ also controls the quantities of elements in the atmosphere by absorbing some and releasing others.
Sorry? Weather definitely isn't the same as air humidity. The rest is utter codswallop.
We have to also remember the fact that earth having a molten interior; has provided a magnetic field that protects us from the cosmic radiation by repulsion.
Not quite. The magnetic field is due to a combination of molten fluids, but also due to their electical conductivity and rotation, see
this. The magnetic field doesn't affect radiation though: Cosmic radiation is absorbed partly by the atmosphere and not repelled by the Earth's magnetic field. If radiation were completely repelled by the Earth's magnetic field, we wouldn't have any light on the Earth, since light is also electromagnetic radiation.
The moon which orbits the earth, gives our planet a gravitational stability without which our climate and weather patterns would be unstable (the planet would be wobbly about its orbit) and hence giving us an erratic atmosphere and irregular protection from the cosmic radiations.
Not particularly true either. The moon may affect the seas, but that's the limit of the gravitational force exerted by the moon upon the earth. Mercury and Venus have no moons, but still have a stable orbit
Conclusion
Our planet is alive and knows how to take care of itself. The human race has maximized its efforts to bring about the death of mother earth, but she has more important threats to worry about like the occasional reversal of her magnetic field, the gradual slipping away of the moon by 4cm a year, and her tectonic rumblings that at times increase the surface areas over which her waters (weather) is lost to the atmosphere and release millions of gases and particles that de-stabilise temperature retention and absorptions.
Planets aren't living beings, they don't worry about things either. And the atmosphere is being heavily destabilised all the time. True, the other things you list are happening, but that's just life as usual.
The age of development of the human race; the use of fossil fuels has not lasted long enough to cause an imbalance in a carbon system to which our contribution is comparable to a drop of water in a litre of milk a year.
Nope. Look at the top of
this page for a nice graph of CO2 concentrations. Actually, I recommend reading the whole page. And also, a drop of water in a liter of milk a year will make quite a difference in a few hundred years even. So you're image isn't particularly serving the purpose you gave it.
The earth is getting warmer because it’s that time in the earth’s cycle when preparations for an impending ice age say 30,000 years from now, are being made. Maybe, a reversal of the earth’s magnetic field is in progress. All in all, we haven’t been here long enough to have caused any harm to the carbon cycle. If poisoning the atmosphere with carbon were our mission, we wouldn’t even have the technology with which to pump the atmosphere with enough carbon to overwhelm the current levels. Not in even 1000 years. Yet, we have been using fuels for about only 300 years.
Preparations for an ice age? The earth doesn't actually control anything that happens on its surface. We might not have the technology to create a large change in CO2 concentrations, but even small changes will have large effects on us. Just so you know, the heating of the earth even now is causing positive feedback with CO2 release by thawing tundra where much CO2 is currently trapped, which will release more CO2, causing more warming etc.
However, all in all, humans are only a short episode in the story of the earth. If we happen to drive ourselves to extinction, then it just serves us right. The planet Earth will still survive fine, only the life forms upon it might change dramatically.
Oh, I just noticed this

A drama being played by some freaks. In case you haven't heard yet, global warming has been changed to 'global climate change'. It shows those freaks just can't make up their minds.
Te change from "global warming" to "global climate change" was an invention of politicians who are quite into euphemisms. For politicians "global warming" sounds too threatening, which is why they changed it. (Politicians are prone to this, think "collateral damage" instead of "civilian deaths/murders" when talking about war.)
And as usual, while the rich nations (USA, Europe) caused all this, it is poor countries that are suffering most. Some people from rich nations even have the cheek to deny that there is such a thing as global
warming.
(Please don't try saying nations such as India and China are terrible polluters, their CO2 release
per person is still considerably lower than that of USA, UK etc. Look at
this nice graph.)
