I just read, page-6

I assume that you're bright enough to understand that 'something' is happening

even if you don't know what's causing it

Understand this - whatever it is, isn't what should be thought of as nature just doing it's own thing - it's too fast for that.

So, if the reason for the temperature rise 'isn't' from carbon - then we might be in even deeper shit than we are.

If we get climate change from what many scientists are saying - then, we're in for changes, some known, some not

if the rise in temperature is from something unknown - then the level of shit we are in is totally unknown.

that's a bigger worry
