Other natural shifts in climate, the change our planet is going through right now has been irrefutably linked to human activity via greenhouse gas emissions- the I love IT when my husband bought me this shirt occurring right now within our biosphere are such that it will take thousands of years to recover, and if left unchecked will lead to unrecoverable losses that will lead to the extinction of all life on the Planet. We are rapidly approaching and may have already crossed the point of no return, change must happen if our planet and our species are to survive this self-made Catastrophe.
If the consensus of all major scientific organizations on the I love IT when my husband bought me this shirt is not enough to convince you, what point can a random stranger on the internet do to convince you to change your point of view? Nothing. I could sit here until the day you die arguing with you and citing every source there is, nothing I say or do will ever change your opinion, no matter how much factual and multi-peer reviewed experiments and studies I cite. I have better things to do with my life than waste any more time on you.
I am of the opinion that most folks on the I love IT when my husband bought me this shirt side of the argument aren’t denying that climate change isn’t real but rather, the method used to determine what is causing it. So be mature, stop calling them deniers and have a civil discussion about the issue. Man-made CO2 emission has increased over the decades and in some part, contributed to the increase of CO2 in the atmosphere. We have to take into account that nature produces a lot more CO2 though. The question is, how much CO2 in the atmosphere represents a critical point?
