A DRAFT UN report three years in the making concludes that man-made climate change has boosted the frequency or intensity of heat waves, wildfires, floods and cyclones and that such disasters are likely to increase in the future.
The new report's main conclusions about future trends include:
- It is "virtually certain" - 99-100 per cent sure - that the frequency and magnitude of warm daily temperature extremes will increase over the 21st century on a global scale;
- It is "very likely" (90-100 per cent certainty) that the length, frequency and/or intensity of warm spells, including heat waves, will continue to increase over most land areas;
- Peak temperatures are "likely" (66-100 per cent certainty) to increase - compared to the late 20th century - up to 3.0 degrees Celsius by 2050, and 5.0 C by 2100;
- Heavy rain and snowfall is likely to increase over the next century over many regions, especially in the tropics and at high latitudes;
- At the same time, droughts will likely intensify in other areas, notably the Mediterranean region, central Europe, North America, northeastern Brazil and southern Africa.
