A Map Shows What Happens When Our World Gets Four Degrees Warmer: The Colorado River Dries Up, Antarctica Urbanizes, Polynesia Vanishes

Human­i­ty faces few larg­er ques­tions than what, exact­ly, to do about cli­mate change — and, in a sense larg­er still, what cli­mate change even means. We’ve all heard a vari­ety of dif­fer­ent future sce­nar­ios laid out, each of them based on dif­fer­ent data. But data can only make so much of an impact unless trans­lat­ed into a form with which the imag­i­na­tion can read­i­ly engage: a visu­al form, for instance, and few visu­al forms come more tried and true than the map.

And so “lead­ing glob­al strate­gist, world trav­el­er, and best-sell­ing author” Parag Khan­na has cre­at­ed the map you see above (view in a larg­er for­mat here), which shows us the state of our world when it gets just four degrees cel­sius warmer. “Microne­sia is gone – sunk beneath the waves,” writes Big Think’s Frank Jacobs in an exam­i­na­tion of Khan­na’s map. “Pak­istan and South India have been aban­doned. And Europe is slow­ly turn­ing into a desert.”

But “there is also good news: West­ern Antarc­ti­ca is no longer icy and unin­hab­it­able. Smart cities thrive in new­ly green and pleas­ant lands. And North­ern Cana­da, Scan­di­navia, and Siberia pro­duce boun­ti­ful har­vests to feed the hun­dreds of mil­lions of cli­mate refugees who now call those regions home.”

Not quite as apoc­a­lyp­tic a cli­mate-change vision as some, to be sure, but it still offers plen­ty of con­sid­er­a­tions to trou­ble us. Lands in light green, accord­ing to the map’s col­or scheme, will remain or turn into “food-grow­ing zones” and “com­pact high-rise cities.” Yel­low indi­cates “unin­hab­it­able desert,” brown areas “unin­hab­it­able due to floods, drought, or extreme weath­er.” In dark green appear lands with “poten­tial for refor­esta­tion,” and in red those places that ris­ing sea lev­els have ren­dered utter­ly lost.

Those last include the edges of many coun­tries in Asia (and all of Poly­ne­sia), as well as the area where the south­east of the Unit­ed States meets the north­east of Mex­i­co and the north and south coasts of South Amer­i­ca. But if you’ve ever want­ed to live in Antarc­ti­ca, you won’t have to move into a research base: with­in a cou­ple of decades, accord­ing to Khan­na’s data, that most mys­te­ri­ous con­ti­nent could become unrec­og­niz­able and “dense­ly pop­u­lat­ed with high-rise cities,” pre­sum­ably with their own hip­ster quar­ters. But where best to grow the ingre­di­ents for its avo­ca­do toast?

Any­one inter­est­ed in Parag Khan­na’s map will want to check out his book, Con­nec­tog­ra­phy: Map­ping the Future of Glob­al Civ­i­liza­tion.
