The Guardian reports: Low-income countries will remain on the frontline of human-induced climate change over the next century, experiencing gradual sea-level rises, stronger cyclones, warmer days and nights, more unpredictable rains, and larger and longer heatwaves, according to the most thorough assessment of the issue yet.
The last major UN assessment, in 2007, predicted runaway temperature rises of 6C or more by the end of the century. That is now thought unlikely by scientists, but average land and sea temperatures are expected to continue rising throughout this century, possibly reaching 4C above present levels – enough to devastate crops and make life in many cities unbearably hot.
As temperatures climb and oceans warm, tropical and subtropical regions will face sharp changes in annual rainfall, says the Intergovernmental Panel on Climate Change (IPCC) report, released on Thursday in Stockholm before online publication on 30 September.
East Africa can expect to experience increased short rains, while west Africa should expect heavier monsoons. Burma, Bangladesh and India can expect stronger cyclones; elsewhere in southern Asia, heavier summer rains are anticipated. Indonesia may receive less rainfall between July and October, but the coastal regions around the south China Sea and Gulf of Thailand can expect increased rainfall extremes when cyclones hit land.
