Widespread flooding in northern Brazil has killed at least 49 people and forced nearly 408,000 from their homes, reports the BBC. More rain is expected in the area for another two weeks. The government has spent $435 million to help flood victims, but food supplies continue to dwindle. Flooding has wiped out many crops, and schools has been shut in 12 states. Experts suspect that global warming may be causing the severe droughts and floods that have ravaged the area in recent years.
