Over the decades I've learned to not get too worked up over any gloom and doom being pushed by scientists, especially relating to climate and health claims. It never comes true and frequently is exactly the opposite of what they predict.
This recent one is a perfect example...

Besides, if I'm wrong and we do bite the dust in 30 years, I have no doubt some life form more worthy of this great planet will take our place. Until then, I plan to rock on.
I recall an environmental studies class in the 8th grade. Teacher was convinced we would see an ice age during our lifetime.
I recall those warnings in school that an ice age was coming. "The Scientists" said so. I have become far more skeptical since then.

I have also learned that "journalists" have very little ability to understand grammar let alone science. Science is not a popularity contest; consensus means nothing. If you start from a non-falsifiable hypothesis, if you don't outline what evidence would change your conclusion, if you can't accurately make predictions from your hypothesis, you are not doing science.
