Bangkok’s future hangs in the balance.

Rising sea levels, unchecked development, groundwater extraction, and rapid urban population growth has left millions vulnerable to natural disasters — scientists warn the city itself may not survive the century.

New analysis by the Nestpick 2050 Climate Change City Index says the Thai capital could be hardest hit by global warming.

And while it is not alone facing such a threat — Venice, New Orleans, and Jakarta are predicted to be underwater by 2100 — it does have a secret weapon in its battle to negate the impact of a hotter planet: renowned architect Kotchakorn Voraakhom who preaches mindful development over mindless construction.

“We are talking life and death in this situation,” says the 39-year-old who is hoping to bring Bangkok back from the brink, as scientists warn extreme weather — flooding and droughts — could ravage the city, leaving as much as 40 percent submerged in the next decade.
