The World in 2100

by u/Aofen

The
sea level rise in this timeline is on the low-mid end of IPCC’s
predictions, a little over 1 foot above current levels. The Maldives and
the Marshall Islands (the two extremely-low lying countries for which
this is a major threat), invest extensively in mitigation measures and
coastal defenses. In both countries some lower lying outer islands are
abandoned, and the population becomes more concentrated in the
better-defended capitals. Several similarly low-lying small islands,
such as Tangier in Virginia, are abandoned. Antarctica, although warmer
than it is today, is still a giant cold nature preserve. There is more
economic activity in the far north though, with the Northwest and
Northeast passages being more viable than today.

The
Congo and South Sudan, being currently much poorer and more
dysfunctional than the rest of the East African Community, are left out
of several of the economic integration agreements in the 2020s and
2030s. The states of the EAC that do not federalize generally retain
close economic relations with the new federation, particularly Rwanda
and Burundi who remain in a currency union and trade block with it.

The
Nagorno-Karabakh conflict remains a sort of frozen conflict throughout
much of the 21st century. Azerbaijan’s authoritarian government is
toppled in a 2034 revolution (after fighting another inconclusive war
with Armenia in 2030), and the new Azeri government is in a slightly
more compromising mood. They eventually agree to a peace deal in 2050.
South Ossetia  and Abkhazia (pressured by the withdrawal of Russia’s
total support) similarly make peace deals with Georgia where they agree
to cede some territory in exchange for recognition.
