CLIMATE CHANGEAs the Earth’s climate warms, United Nations scientists are predicting an increase in heat waves, rainfall and flooding, stronger cyclones and more intense droughts across the globe this century.

In a report released last week in Uganda, the United Nations Intergovernmental Panel on Climate Change – IPCC – urged countries to rapidly adopt disaster management plans to adapt to the growing risk of extreme weather. The report gives differing probabilities for weather events, but the thrust is that extreme weather is likely to increase and that the likely cause is humans.

The IPCC defines “likely” as a 66-100 per cent probability, while “virtually certain” is 99-100 per cent. The report says it’s virtually certain that increases in the frequency and magnitude of warm daily temperature extremes will occur on the global scale in the 21st century.

A 1-in-20 year hottest day is likely to become a 1-in-2 year event by the end of the 21st century in most regions. It is very likely that the length, frequency and intensity of heat waves will increase.  Heat waves would likely get hotter by 1-3 degrees Celsius by mid-21st century and by 2-5 degrees by late-21st century :: Read the full article »»»»
