I've worked with and listened to enough scientists that I've become skeptical of certain branches of science; particularly those that try to make general predictions based on incredibly complex data which encompasses an almost infinite number of variables.
Several things which make me doubt:
- Having worked on extremely complex software projects, I don't believe that any human being is capable of understanding or simulating something as complex as the earth, they will almost certainly exclude the vast majority of variables; many of which may not seem relevant to our primitive human minds but which may in fact be critical once you factor them in combinations with all other variables.
- The earth was hotter at several points in the not-so-distant history. The Earth's climate has been constantly fluctuating.
- Humans only produce 3% of the total CO2 released in the atmosphere each year. I wouldn't be surprised if the annual average fluctuation in CO2 produced by geothermal activity alone is higher than 3%.
- Scientists acknowledge that more CO2 means a greener earth because plants strive on CO2 but they fail to acknowledge the possibility that more plants would take out more CO2 from the atmosphere so even with these primitive models it's looking more like some kind of equilibrium will be reached rather than a 'point of no return' as climate scientists keep advertising.
- Life on earth has always been evolving and can continue to evolve to handle changes in temperatures. The species which don't adapt will die out and this is fine, it has always been like this.
- If the Earth can go from being a burning ball of magma (as it was millions of years ago) to what it is today, then surely it can recover from a few degrees higher than normal. Without hindsight, nobody could have predicted that this burning ball of magma would become the lush planet that we have today and yet scientists are claiming that they can make predictions from an initial state which is much more complex and less predictable than that relatively simple ball of magma.
- Climate scientists need jobs and they wouldn't have any if they didn't continuously create fear to keep public funding coming their way. At some point in the past, for reasons unknown to us, some powerful people decided to give climate scientists a platform and a voice on the world stage and now they make heavy use of it.
