Save The World: ‘Global warming triggering to floods’

SUKKUR: The increased frequency and intensity of floods, droughts, heat waves and tornados are a result of global warming, explained Univerisity of Sindh’s Prof. Mohammad Rafiq Dhanani, who is the chairman of the department of geography. He gave a lecture at the Shah Abdul Latif University in Khairpur this week. “Another effect of global warming is the spread of diseases like malaria which had been eradicated from certain areas before but have made an aggressive comeback.” The professor said that there has been a 100 per cent increase in temperature over 50 years because of carbon dioxide, methane and the ozone which reflected heat energy back to the earth’s surface. According to Dhanani, the increase in temperature, sea levels is happening because of thermal expansion of the ocean. The total annual power of hurricanes has already increased since 1975 because their average intensity and average duration have increased.
