(University of East Anglia) Global carbon emissions are on the rise again in 2017 after three years of little to no growth, according to University of East Anglia researcher. Global emissions from all human activities will reach 41 billion tonnes in 2017, following a projected 2 percent rise in burning fossil fuels.It was hoped that emissions might soon reach their peak after three stable years, so this is unwelcome news for those at the UN Climate Change Conference (COP 23), Bonn.
