Global Warming and Climate Change} Let's run some numbers by you.

Around 2.5 million years ago, the planet was just starting to run low on the life blood of the plant life, carbon dioxide in the atmosphere! The levels were probably around 190 parts per million, or put it another way, .019% ! The good thing was that there was almost no ice on the planet, and very few arid or semi-arid area's on the planet. So around this time, the temperature was slowly lowing, both due to what later would became know as the "Milankovitch oscillations" and the very low amount of the greenhouse co2. And the planet enter into the first ice age for Almost 12 million years, and before that around 245 million years! The good part of all this was that at that time there was very very large reserves of carbon in the great oceans of the planet. However the only way that this carbon would become available to enter the atmosphere, was as a gas, when the ice on the planet had lowered the oceans by hundreds of feet around the whole planet. (There were other gases at work, such as methane) This is why the cycles of more ice on the planet and less ice on the planet, is so out of balance. It takes 10's of thousands of years to create enough ice to be staged on the planet to release the necessary carbon dioxide back into the atmosphere, but the carbon sequestration of that same carbon is much quicker to occur, The inter glacier periods would be even shorter, if the sizes of the arid and semi-arid area's did not keep increasing around the whole planet at this same time. Carbon sequestration, is fairly consistent year in and year out, of taking around 10 Gt/c out of the cycle of plant life. And volcanic action is somewhat more unstable year in and year out, but is estimated to return on average only around 3 Gt/c each years. Now jump ahead that 2.5 million years, and the great reserves of the oceans are almost gone. Arid and semi-arid area's have increased to around 1/4 of the land area, of the planet, and getting larger ever year! Add up all of the available carbon left and you get app. 45,860 Gt/c not even close, to let the planet survive another ice age cycle!

Global Warming and Climate Change} Lost of available carbon vs. too much C02 in atmosphere!

Global Warming and "The life cycle of a planet" By Daniel Kadavy  402-890-7946  Cortland Nebraska                                                                                                                                                                                                                The planet is running out of carbon, which is the mainstay of all life on the planet! Something has to be done to mitigate this. And yet Global Warming is changing ...

503 DIII Humanity is the only species that have to pay to live and survive. while there are a few exceptions to this rule, they are few and far between!

What does that say about how we live? It means that we have very little say in most aspects of our lives if we wish to live in a house, we must pay for that privilege with taxes, energy, insurance, maintenance, and keeping the standards that each place puts upon the owners, cutting grass, moving snow, and so many other requirements to fall within acceptable parameters of society! We must obey laws we may disagree with, nor have any input in their adoption or application! While there are many different arrangements of governments around the world, even the ones that are voted in or out of power by the masses are never truly fair in explaining to their constituents what they are going to attempt to do if elected! Yet this is the world we live in while we attempt to understand what 3.5 billion years of carbon sequestration have forced our planet to go through, including almost every single extinction event that has occurred in the history of our planet!  So the problem that we face is...

CCLXXIV Global Warming and Climate Change} Let's talk more, about the 50,000 gigatonnes of available carbon, that is left for all life on the planet!

First, how do scientist's come up with around 50,000 gigatonnes of available carbon left on the planet? Some of the amounts can be directly measured, how much there is in the atmosphere is one of the most researched numbers on the planet! That figure of 415 parts per million equals around 800 gigatonnes of carbon, in the form of carbon dioxide. 560 gigatonnes in plant and animal life are based on both satellite images for how much plant life is on the planet during the year and measurements that were taken by hundreds of people every year all around the planet. How much soil carbon, is taken by averaging soil carbon from all over the globe this amount is said to be 1,500 gigatonnes. The amount of "fossil Fuels" is the amount of "known" reserves found by mainly oil accompanying who has been looking as far and fast as they can, that amount is estimated at 4,000 gigatonnes (The carbon sequestrated in fossil fuels would only become available if mankind continues to ...
