As this blog has discussed before, NO ONE CAN PREDICT THE FUTURE. No one. Not the psychic you may see on television, the person reading tarot cards, no one. Not the people who write apocalyptic books like "The Population Bomb" (totally discredited now), no scientist and no computer. People can speculate and occasionally guess right, but never reliably. Which makes all this "climate emergency" completely bogus.
I'm not sure where the timeline originated. An American freshman congressperson may have started the recent hysteria and everyone just jumped on the bandwagon. There have been many such predictions in the past:
None, of course, have come true and there is zero reason to think current predictions will either, with the occasional lucky guess. All this is scare tactics.
Sadly, children are very often the targets of such fear tactics. There are reports of children having nightmares about climate change. Yet, it's all fabricated fear. The 2° rise the IPCC set as a limit? As far as one can tell, they pulled the number out of thin air. They have zero evidence that a two-degree rise in a "global average" can cause catastrophic warming. Sea level rise is not increasing, the ocean is not acidifying.
Could things get worse? Sure. There's no way to know. Things have an equal probably of getting better or not changing much at all. Things could get better or worse due to many factors that have nothing to do with CO2 or human beings. History is full of foolish, evil and wrong things humans did to themselves without involving nature. Gullibility and apathy are can kill or make one's life very, very depressing. Fight these, not an invisible, mathematically created enemy.
There is no reason to fear future climate, to skip school to protest (learning is what the job of a child is, not protesting), none of those things. Few things steal the future: death, illness and malevolent governments do. Climate cannot steal the future. It can only require adaptations.
The proper response is to learn as much about living and dealing with reality as much as possible. Humans have adapted to many different environments for centuries. There's no reason humans can't continue to unless they chose to fail. Let's not choose to throw away the future on the ridiculous fear-mongering of the global warming politics.
A word on the deification of Greta: If ever there was PROOF beyond a doubt that global warming is nothing but politics and religion, the Church of Sweden has declared Greta "the successor to Jesus Christ". First there is no successor to Jesus Christ. That's absolutely fictitious. Second, this is RELIGION, pure and simple. It is NOT about science at all, no matter how many times the Greta one may pretend to believe that or repeat the lie that it is science. Now, if you want to swear allegiance to a religion dead set on destroying humanity and your futures, that is your choice. However, please do not try and blame science for "stealing your childhood". Adults stole your childhood and you went along with the lie of global warming out of religious or political need, NOT because you're scientific. Please do not blame the thinking, scientific people for your despair. While living miserably never really made sense, humans do have that choice. One would hope you would choose to enjoy the wonderful, incredible times in which you live and celebrate humanity, rather than cower in fear.
