You talk as if you know but in reality you are going on a hunch and simply guessing because to you it doesn't seem possible? While you may not be a global warming denier, your comment shows exactly the same charcteristic of non scientific guesswork as we hear from skeptics. The 'I dunno but it doesn't feel like it' pseudo-scientific opinion but not one based on actual scientific analysis.
You made a statement and typically you offer NO scientific data to support your view nor do you even cite scietists or reports that might share this opinion.
The statement is based on the cumulative stress factors that are occurring all at once. In particular the astoundingly rapid rate of change which exacerbates the deleterious effects of all the other stress factors but it is not the solitary stress factor which is what I think you believe..
In other words, the Earth has never undergone anything like what it is undergoing now. Not only the unparalled rapid rate of change but also ocean acidification, catastrophic warming, ozone depletion, unparalleled amounts of pollution including billions of tons of carbon every year plus pollution by nitrous oxide, methane, CFCs, mercury, pesticides, chemical contamination by tens of thousands of chemicals, GMOs, nuclear radiation and a host of other environmentally damaging practices that range from deforestation to the introduction of invassive species.
The planet Earth has never experienced anything at all like what it is experiencing now. Never! For example There have been times when the polar ice cap has melted but the process took thousands of years. However, we are doing it in roughly thirty years once the initial tipping point was reached.
If the deniers and skeptics don't know enough and usually don't want to learn about the true state of things, that doesn't excuse you bowing to their disbelief by adding your own. You should stop hurrying to be first to comment just to be first and instead do some adult level research to fact check your post before you post it. You treat commenting like it is a kid's game but fact checking your stuff...
...would be WISER.
