No, it’s not reasonable at all.
I believe that climate change is real, and that human activity contributes. However, humanity is part of nature and the climate has always changed throughout the who history of the planet.
I also believe that despite climate change being real, and a threat, climate scaremongering has become an industry, with vested interests.
The timescales and extent of the impact is exaggerated and used to spread fear and alarm. As usual though, people are making money out of it.
The environment should be cared for and protected simply because it is the right thing to do, not because of fear of fabricated apocalypse.
It is sad OP to see you in such a state of fear and alarm over something you can’t control and over which there is such hysterical hyperbole.
All the efforts of humanity to control the climate could be undone tomorrow if the super volcano under Yellowstone explodes. That probably won’t happen though, and neither will the catastrophes predicted by the climate industry through their media partners.
