A draft UN report three years in the making finds that man-made climate change has boosted the frequency or intensity of heatwaves wildfires floods and cyclones and that such disasters are likely to increase in future.
The main conclusions about future trends include:
• It is “virtually certain” – 99-100 per cent – that the frequency and magnitude of 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 heatwaves will increase over most land areas;
• Peak temperatures are “likely” (66-100 per cent certainty) to increase – compared with the late 20th century – up to 3C by 2050 and 5C 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;
• Droughts will likely intensify in other areas notably the Mediterranean region central Europe North America northeastern Brazil and southern Africa.
