Flooding in Central Asia and southern Russia kills scores and forces tens of thousands to evacuate to higher ground

Unusually heavy seasonal rains have left a vast swath of southern Russia and Central Asia reeling from floods, with dozens of people dead in Afghanistan and Pakistan and tens of thousands forced to flee their homes in Kazakhstan and Russia. 

Authorities say the flooding — the atypical intensity of which scientists blame on human-driven climate change — is likely to get worse, with more rain predicted and already swollen rivers bursting their banks.
