Global heating to blame for flooding in Australia

I sympathise with the flooding suffered by the people of Durban (Spotlight, 6 May), but they are not alone. Australia has also suffered.

For example, Lismore in north-eastern New South Wales has been flooded three times this year. The first flood, on 28 February, at 14.4 metres, broke the previous record by almost 2 metres. Sydney also suffered catastrophic flooding during the same period. Climate experts are convinced that global heating, which increases marine evaporation and the water vapour content of the atmosphere, is to blame.
