This planet is an extremely complex and dynamic system of uncountable interacting elements.
There is a game called as "Life" which is most commonly implemented in C language. It basically creates a 2 dimensional array and "lights" up cells according to some few simple basic rules. However once the code is run, after some time extraordinarily complex patterns are seen and new patterns emerge. As if the code is living, the lit up cells are termed to be alive, hence the name Life.
Its the same with Earth, except that this planet is an infinite dimensional array, and a large number of incredibly complex rules govern interactions between the variables which light up the cells.
One feature of the game was that when the initial pattern changed the subsequent patterns changed drastically. Also the initial pattern decided whether the lit up cells will spread apart, dilute in concentration and die, or they will form other patterns which will be sustained.
Life appeared/arrived/started on this planet 3.2 billion years ago. Then around 2.4 billions years back photosynthesis appeared. And the sheer number of the cyanobacteria was enough to change the composition of the whole damn atmophere of this planet. The air turned poisonous with a new oxidising agent. Level of CO2 fell drastically, temperatures dropped. Climate Changed.
Present day Earth, same process is happening, inhabitants of the biosphere are playing with patterns and the outcome is bound to change the state of this planet and problem is we don't know where these changed pattern will lead to.
But my stand, as it has always been, on climate change is as follows: Cyanobacteria utilized the nutrients available to them to the fullest, in the process excreting Oxygen, which was at that time an extremely poisonous gas to other life forms, which were predominantly Anaerobes. This phenomena pushed anaerobes, which ruled the earth into such places such as seafloor, intestines and bottom of marshes. Today we are also utilizing the resources available to us to the fullest, and in the process we are excreting poisonous waste which is bound to affect the abiosphere and other life forms. However if cyanobacteria didn't stop why should we. This planet has always adjusted to whatever perturbations it encountered, that's how the system works, by simply following the rules. If the changed patterns cause some populations (maybe/hopefully Humans) to die off, well thats how this game of Life works. The rules just cant be changed.
P.s. This is my post as a contribution for the Blog Action Day cause of this year Climate Change. Cant say it furthers the cause, but i registered and so i blogged!! :)

@ sid -
i agree that any species does what it is programmed on this planet. Those changes may be undesirable for the planet or other life forms. But i wonder if cyanobacteria made the changes for iteslf? The answer is clearly a big YES. it did so coz it wanted to survive at the cost of others. Now when it comes to us things change a bit! The changes we bring about are not beneficial to us either...they pose equal harm to us or may be more. So this time its the question of our actions causing undesirable changes that would in turn question our need of survival..thus such changes are not acceptable for our existence on this dynamic planet!!
