The other problems are other gasses and processes that can release trapped CO² and CH⁴ methane, and that the extra heat in the system and H²O melting may disrupt ocean currents, now, rather than century's into the future, leading to sudden climate changes world wide, which could also trigger sudden ocean rise. They are not called tipping points for nothing, and it is established fact that those points have been reached numerous times before, and that we are pushing the climate closer, through our own actions.....we roll a 2 and a 5 and some natural fluctuation might push it all back, snake eyes and we get a civilisation level challenge to survive with our technological base intact, if we can.
