In 2010, global heating triggered a heatwave in Russia which caused wildfires, some passing over the grain belt. After losing much of this crop, they then introduced export bans and increased the world price of grain. Consequently, Mozambique which is heavily reliant on important food had to then rise the price of their bread by 30% which caused riots around food stores. Their harvest had been hit by drought too - the World Development Movement was then said to be 'gambling on hunger' in financial markets.
