James Bay Approved, page-63

I don't normally engage with climate denial memes (this is one of them), but suffice to say that natural causes (they're complicated, but they have been shown through vast amounts of scientific evidence, in the largest academic endeavour in the history of humankind) were the cause of millions of years of glacial and interglacial periods, resulting in an approximately 10,000 year period of warm temperatures and stable climate, up to now, known as the Holocence, that has allowed humankind to develop agricultural and technology, leading to complex social structures and civilisation. The difference with the warming now is that it is unprecedented in its rapidity and it is due to human intervention rather than being due to natural causes.
