Global Warming...fact or global conspiracy

We have since learned that, due to man's intervention, we have inadvertently reversed the prevailing trend towards a Glacial Period in our planets' climate. We are now facing a contrary situation. Earth's climate, we are told, is becoming warmer.
Furthermore, we are told that this course cannot be reversed (again. sic). This impending age of increasing temperatures, melting glaciers and polar ice caps cannot be stopped. Climate Change can, however, be somehow delayed or mitigated.
Now we find ourselves, as a planet, promoting efforts that, when viewed with a different paradigm, can easily be deemed as being ludicrous as a bulwark against the inevitable. Through the Kyoto Accord, we see one side of the planet sacrificing their economies in an effort to stem their greenhouse gas emissions while the other side of the world is given, literally, a ca rte Blanche as to their emission levels. Speaking in realistic terms, this is an unrealistic approach.
The we find ourselves, collectively, assuaging our supposed guilt about our extravacances; airplane travel, SUV use, home and business power usage , by purchasing carbon offsets. A means to counter-balance our personal and collective greenhouse gas emissions through the funding of what amounts to 'planting a tree to receive a social indulgence for taking a flight to Hawaii'. Does this really do anything to delay the, as they put it the inevitable?
Could there be forces that have recognized a genuine global disaster afoot and, recognizing it's inevitability, are seeking to gain profit from the situation? By profit, I mean to gain from this Global Warming Alarm to position themselves to survive whatever might be coming; on a personal level for the short term or ,collectively, on a national or societal level?
