"A preliminary global temperature curve shows that marine life diversified in extreme heat (1) before land-based plants absorbed carbon dioxide (CO2) and polar ice caps formed (2). Volcanoes and erosion swung CO2 levels up and down (3), but mammals evolved in a warm period (4). Now, humans are rapidly warming the climate again (5)."

The chart explains that the human activity effect is at the magnitude of cataclysmic volcanoes, and other global geological/ecological effects. I sure vote that we don't accept the status quo that this stuff happens over millions of years already. We should care, since this time, we actually exist. Nevertheless, I understand how this makes the conversation harder, which is unfortunate but expected in any nuanced discussion. I, by no means, am an expert and I had a similar reaction in the beginning.

To put things in perspective, our current effect in some hundred years, used to take thousands, if not 10s/100s of thousands of years.
