Why this quadrant

The starting mechanism is a simple, single-cause, thin-tailed payoff, an annual monsoon overflowing known floodplains, but heat-driven glacial melt, record rainfall multiples, and decades of floodplain construction compounded simultaneously, fattening the tail and turning a linear, budgeted-for hazard into a nonlinear cascade across agriculture, public health, poverty, and international climate finance.
