DESCRIPTION: In this special live Sustain What webcast, join host Andy Revkin of the Columbia Climate School and http://revkin.bulletin.com in a brisk solution-focused discussion with top experts of pathways to risk reduction in the world’s hundreds of crowding deluge danger zones.
Humans are profoundly heating the climate and changing storm patterns through a surge in emissions of heat-trapping gases and other pollution. But there’s also been a simultaneous surge of settlement in zones prone to flooding -- producing what some geographers call an “expanding bull’s eye” of exposure to climate-related threats like floods. And of course the poorest and most marginalized populations are always hurt most.
A pioneering study, published in Nature on Wednesday, has greatly raised estimates of population growth in flood-affected regions and offers sobering projections of much more flood exposure through 2030 without big changes in policy at every scale. Luckily the work, sifting millions of high-resolution satellite images, has also produced a new open-access tool, the Global Flood Database (http://global-flood-database.cloudtostreet.ai), that offers officials at all levels, the financial world and communities a clearer view of the exposure they’ve created and a chance to shape safer development paths in the critical years ahead.
