PARIS (AFP) — Drought is killing off trees in Brazil's fragile Amazon rain forest and depleting the region's carbon reservoirs -- an ecological double-whammy with devastating implications, according to a study published Thursday.

The Amazon's lush vegetation in a typical year absorbs nearly two billion tonnes of carbon dioxide, one of the chief culprits causing climate change.

But a 30-year study published by the journal Science found that the world's largest tropical rain forest is surprisingly sensitive to drought, and that the resulting loss of vegetation will have a greater-than-anticipated effect in causing a sharp spike in greenhouse gases.

The Amazon tree canopy which absorbs massive amounts of greenhouse gases often succumbs to the effects of dryness, thereby accelerating global warming by not absorbing CO2, scientists said.
