Hate to agree with such a dismal premise but... yup. As far as I can tell, we're gonna punch right through 1.5c next year, there's gigatons of ice shelf coming off Antarctica, and banks are still supporting more petroleum exploration and exploitation. People are going to cook this winter (summer's coming down there) in the southern hemisphere, and then more will cook in the northern hemisphere this coming summer. And I mean that literally. The human body isn't capable of operating at the temps we're pushing; humidity will also go up globally because hotter air holds more water, which will kill more. Oh and that 12-hr hurricane that beat Acapulco into rubble? We're gonna see a lot more of those too, the ocean has absorbed as much heat as it can hold to the point that the gulf stream is halting because the convection currents that keep the system going are too warm. Water off the coast of florida was in the high 90s this summer, bet it's worse next summer.

If the Ross starts to calve quickly, it's going to get apocalyptic rapidly for anyone living near sea level.
