Amazon hit by climate chaos of floods, drought

Experts suspect global warming may be driving wild climate swings

SAO PAULO – Across the Amazon basin, river dwellers are adding new floors to their stilt houses, trying to stay above rising floodwaters that have killed 44 people and left 376,000 homeless.

Flooding is common in the world’s largest remaining tropical wilderness, but this year the waters rose higher and stayed longer than they have in decades, leaving fruit trees entirely submerged. Only four years ago, the same communities suffered an unprecedented drought that ruined crops and left mounds of river fish flapping and rotting in the mud.

More extreme weather possible

While a definitive answer will take years of careful study, climatologists say the world should expect more extreme weather in the years ahead. Already, what happens in the Amazon could be affecting rainfall elsewhere, from Brazil’s agricultural heartland to the U.S. grainbelt, as rising ocean temperatures and rain forest destruction cause shifts in global climate patterns.
