Gaia's response to climate change?

We project the outcome of the current climate based on models. Of course, models are just - models. They extrapolate based on existing data, and do some math. They present a situation if everything continues as-is.

Then there is the Gaia hypothesis. That's just - a hypothesis, but a strong one. Established by James Lovelock, a NASA scientist, end of the 60s, it basically states - in very scientific, non-romantizing terms - that the planet has been self-regulating the temperature over mullions of years. It seems to suggest that it has been regulating the temperature for life to thrive.

Let that sink in. The theory was formulated from a very scientific point of view, but was later called Gaia due to Lovelock's friend's William Golding, a novelist, suggestion.

Initially it was named "Earth feedback hypothesis".

Be the name as it may - if the hypothesis holds, then we can expect "feedback" actions from the planet. In other words - the planet won't just sit there and let itself fry.

How could that look like? Unpredictable and unforeseeable in time and form. But if it really is to counteract the level of heating, then nothing less than catastrophic (more for humans, less for the planet as a whole) can be expected, as otherwise it won't be able to self-regulate again. Maybe a huge volcano or caldera eruption, tapering sunlight for a while. Some unkillable bug decimating the population. Whatever. But it would try to restore benevolent conditions for life.
