Toxic Montana Lake's Extremophiles Might Be a Medical Treasure Trove

I find it so hard to even have an opinion about global warming because the questions and subject is so loaded.

First of all the global temperature doesn't stay the same, it's constantly rising and falling. Earth has ice ages which are defined as ice sheet existing on planet as is the case currently at our poles and we have glacial periods and interglacial periods which are defined as more extensive ice sheets and the times between them.

The earth naturally undergoes periods without any ice caps all at the poles. Volcanoes erupt all the time (in the geological sense) and put out way way more gases that change the atmosphere more profoundly than man. A bunch of small volcanoes can cause global warming in a few thousands of years and a large super volcano explosion can send us into an ice age and or glacial period overnight.

Earth weather does indeed change and that is the norm.

Human beings are unquestionably contributing to climate change. But how bad is it really vs the climate shifts that would occur anyways if we didn't exist? Where no one makes the distinction is calculating where the climate would be without humans. Global temperatures and been consistently rising since modern man appeared at the beginning of the decline of the last glacial period approximately 12,000 years ago. We probably didn't significantly effect climate until at the earliest 2000 years ago although I suspect is more like after 1200AD. But the earth was warming anyways...

Second they don't comment on possible benefits climate change can have in some areas vs the bad in others. No one seems to even notice that without ice caps we get a new continent to inhabit.

Further it seems to me we are overly focused on greenhouse gases and the atmosphere and temperature. I think a bigger issue of consequence is deforestation of unoccupied land and the over farming of the oceans. The more variety of life the quicker the adaptation rate.

And while we may be totally fuck up this planets current ecology I doubt we could destroy it completely even intentionally. Given our best shot to turn the earth into a desert I bet the earth would be teaming with life again 100 million years later.
