The Great Debate UK

The unusually large rainfall from this year’s monsoon has caused the most catastrophic flooding in Pakistan for 80 years, with the U.N. estimating that around one fifth of the country is underwater. This is thus truly a crisis of the very first order.
Heavy monsoon precipitation has increased in frequency in Pakistan and Western India in recent years. For instance, in July 2005, Mumbai was deluged by almost 950 mm (37 inches) of rain in just one day, and more than 1,000 people were killed in floods in the state of Maharashtra. Last year, deadly flash floods hit Northwestern Pakistan, and Karachi was also flooded.
It is my clear view that this trend is being fueled both by global warming (which also means extremes of rainfall are also a growing world-wide trend), and indeed potentially by any intensification of the El-Nino/La-Nino cycle.
