The world is in a new era of “climate change reality”, with carbon dioxide in the atmosphere reaching a symbolic threshold which it will not fall below for many generations, scientists have said. In 2015, for the first time, carbon dioxide levels in the atmosphere were at 400 parts per million (ppm) on average across the year as a whole, the World Meteorological Organisation’s (WMO) annual greenhouse gas bulletin reveals.
The pledge to eradicate hunger and poverty must go hand in hand with rapid transformations of farming and food systems to cope with a warmer world, FAO said today in a new report. Agriculture, including forestry, fisheries and livestock production, generate around a fifth of the world’s greenhouse gas emissions. Agriculture must both contribute more to combating climate change while bracing to overcome its impacts, according to The State of Food and Agriculture 2016.
