«Trump has pledged to take actions to round up and deport millions of Americans, decimate unions, take health care coverage away from millions, threaten women's reproductive rights, and
allow runaway climate change to continue — all while deregulating the economy and cutting taxes for the wealthy.
Once the ice reaches the equator, the equilibrium
climate is significantly colder than what would initiate melting at the equator, but if CO2 from geologic emissions build up (they would, but very slowly — geochemical processes provide a negative feedback by
changing atmospheric CO2 in response to
climate changes, but this is generally very slow, and thus can not prevent faster
changes from faster external forcings) enough, it can initiate melting — what happens then is a
runaway in the opposite direction (until the ice is completely gone — the extreme warmth and CO2 amount at that point, combined with left - over glacial debris available for chemical weathering, will draw CO2 out of the atmosphere, possibly
allowing some ice to return).
About 1980ish, some old ideas like the greenhouse effect were brought out of mothballs and re-examined with new tools and techniques; simultaneously several researchers and theoreticians released their notes, published, or otherwise got together and there was a surprising consilience and not a small amount of mixing with old school hippy ecologism on some of the topics that became the roots of
Climate Change science (before it was called Global Warming); innovations in mathematics were also applied to climate thought; supercomputers (though «disappointing» on weather forecasting) allowed demonstration of plausibility of runaway climate effects, comparison of scales of effects, and the possibility of climate models combined with a good understanding of the limits of predictive power of weather
