There is no benefit to life from anthropogenic climate change anywhere on Earth. 350 ppm of CO2 was the perfect balance that life is made for.
We are up to about 420 ppm of CO2 now. We raised it 70 ppm in less than 200 years. Unreal.
- candiddevmike 3y agoAny interesting links around why 350 is the target? I searched and everyone keeps quoting the same climate guru without any reasoning behind why that number specifically was chosen.
- vbezhenar 3y agoCO2 was below 400 PPM for the last 5 million years and around 350 PPM was the last 100 000 years. It's just the number the nature stabilized at, before human civilization changed it. Historically life endured all kinds of PPM up to 2000 and above. So probably nature will adapt.
- oppositelock 3y agoWhy is 350ppm the perfect concentration? Higher is better for plants, because most are carbon limited, for example. The Carboniferous era, whose biosphere sequestered so much carbon, had far higher concentrations. I’m not disagreeing, but that seemed like a statement out of the blue.
- tzs 3y agoAre you sure you didn't mean 250 ppm? That's a lot closer to what it was 200 years ago. 350 ppm is around 1990 levels and it is hard to see how 1990 levels would be what life was made for.
