LAHORE, Sept. 1 -- Pakistan's eastern Punjab province is dealing with the biggest flood in its history, a senior official said Sunday, as water levels of rivers rise to all-time highs. Global warming has worsened monsoon rains this year in Pakistan, one of the countries most vulnerable to climate change, according to a new study. Downpours and cloudbursts have triggered flash floods and landslides across the mountainous north and northwest in recent months. Residents in eastern Punjab have also experienced abnormal amounts of rain, as well as cross-border flooding after India released water from swollen rivers and its overflowing dams. "This is the biggest flood in the history of the Punjab. The flood has affected 2 million people.
