The human race (along with all other life on Earth) has survived through many
reversals. The most recent was the Laschamp event, about 41,400 years ago.
During the transitions, the field fell to 5% of its current strength.

really noticeable in the fossil record, so I'm not worried.
Considering that the events that _are_ noticeable in the fossil record involve
killing off like 99% of all living creatures, in order to kill off 90% of
species... I don't quite find that fact as reassuring as you do.
We could get a rerun of the Permian Terminal Event if we don't do
something about climate change; would that satisfy you?
"An additional note to readers: every carbon atom in your body was once
atmospheric CO2. Every molecule of oxygen that you breathe was once
atmospheric CO2. That is how necessary, not just “beneficial”, that CO2
is to all life."
"WARMER IS BETTER. FIGHT THE ICE."
But it's NOT just "warmer". Asuuming we don't kill the Atlantic
Conveyor, it's _still_ "warmer in the summer--sufficiently that there's
no permafrost anywhere south of Fairbanks", BUT significantly, while
winters may or /may not/ be shorter, they /will/ have lower 'lows', at
least for several days at a time for anywhere that was previously south
of the polar vortex. That's because the air that /had/ been trapped over
the permafrost region by the vortex quickly invades the entire temperate
zone (thus even Florida is likely to be prone to yearly frost in the
future, let alone the rest of the South).
More importantly for Trump's liege-lord, it will make Northern Russia
one of the most productive agricultural regions on the planet in the
summer, and it will also have ice-free summers on the Arctic Ocean so
that said produce can be shipped anywhere much more quickly than before.
At the same time, however, it's likely to make those same areas even
LESS livable than before in the winters, so it'll either be a place of
internal exile, or the Russians will take up a semi-nomadic lifestyle
where the entire farming community becomes "snowbirds".
If we DO kill the Atlantic Conveyor (and the influx of COLD freshwater
right where it turns east, as Greenland begins living up to its name,
means it's a real possibility), the Mediterranean will cease having a
"Mediterranean climate" relatively quickly and become much more like the
Great Lakes region, since it's at a similar latitude. That...would be
/very/ hard on North Africa in particular, though it /might/ mean the
Sahara begins shrinking as one thing NO one will accuse /it/ of being is
a "cold desert".
Anthropogenic climate change is not something you want to invite unless
you want to tell me where we're supposed to grow citrus and avocado when
there are yearly frosts in Winter Haven and the Baja.
