I think the headline is just trying to be objective and let the readers come to their own conclusions.
Climate change has always been happening. What is "normal" has always been changing. The Azolla event led to the decrease of atmospheric CO2 from 3500ppm to 650ppm over the period of 800k years. Humanity has (so far) increased atmospheric CO2 from 280ppm to 400ppm. Yes, we're faster than Azolla. But we'll probably stop or be stopped before we reach 3500ppm.
> So, this is all a part of natural cycle. Humans are part of life on Earth. Some life on Earth captures CO2, and the other emits CO2, until it runs into some consequences; then the cycle repeats.
