There were three sentences. Which one exactly was hyperbolic?

- "We are leaving the conditions that work for humans and other animals". We're outside the envelope (the historical range) of biotic and abiotic conditions that defined our species' existence on earth for the duration of our time as a species. We are seeing climate extremes never before experienced by the genus homo, let alone homo sapiens. This is a matter of climatic record, absolutely no controversy here.

- "3 billion climate refugees in the next 30 years"? That's a future prediction so obviously we can't confirm or deny it. We've "only" seen 100s of millions globally displaced already from small-scale recent collapses. But those have other causal factor in addition to climate. Still, sea level keeps rising. Water extraction continues sinking coastal water tables into brackish water. Extreme storms happen more and more frequently. Most people on earth live near the ocean. Totaled property damage is more and more common. 3 billion people displaced in 30 years is plausible given the recent trends. It might be less if we're lucky.

- "We must slow down the climate catastrophe now." Given the ongoing catastrophe, I fail to see any hyperbole in this statement.
