“When I began my scientific career I was told I could only focus on one field, one discipline. That felt like having a library, but being allowed to read only half of the books. Why? I don't like to be limited. How about I give you 10 independent records from multiple disciplines that all say climate change is happening and we caused it? How about I show you how it's affecting our health, in 15 different ways. That's called consilience.”
