In the Andes of South America and across the mountains of Central Asia, the glaciers are receding. As temperatures continue to warm, their melting will bring more water to farms and cities earlier in the growing season, raising the risk of damaging floods. Within a few decades, however, the risk of flood in these areas will become risk of drought. Without action to stop the drivers of climate change, most of the Andean glaciers and two-thirds of Central Asia’s glaciers could be gone by the end of the century.These changes are already underway, with global temperatures 0.8 degrees Celsius above pre-industrial times, and the impact on food security, water supplies and livelihoods is just beginning.A new report explores the impact of climate change in Latin America and the Caribbean, the Middle East and North Africa, and Eastern Europe and Central Asia and finds that warming of close to 1.5°C above pre-industrial times is already locked into Earth’s atmospheric system by past and predicted greenhouse gas emissions. Without concerted action to reduce emissions, the planet is on pace for 2°C warming by mid-century and 4°C or more by the time today’s teenagers are in their 80s.The report warns that as temperatures rise, heat extremes on par with the heat waves in the United States in 2012 and Russia in 2010 will become more common. Melting permafrost will release methane, a powerful greenhouse gas that will drive more warming in a dangerous feedback loop. Forests, including the Amazon, are also at risk. A world even 1.5°C will mean more severe droughts and global sea level rise, increasing the risk of damage from storm surges and crop loss and raising the cost of adaptation for millions of people.
