Is climate change man-made or natural? In this video, I discuss how we can tell the difference between human-induced climate change and natural climate change, specifically regarding the modern climate trend.
0:00 How do we know it’s us?
1:18 Timing is not a coincidence
2:01 Tracking how much C we burn
2:32 C isotope signatures don’t lie
6:28 Associated oxygen depletion
8:20 Models (not the kind you think)
9:31 ‘Small amount’ of C emissions = misleading
