The Guardian view on climate policy failures: don't give up | Editorial

News that governments are not meeting targets is alarming, but the actions of activists are a reason to hopeThe world is failing to combat the threat of climate change. Global carbon dioxide emissions from coal, oil and gas increased by 1.6% in 2017, after three years when they rose little or not at all. Demand for oil is increasing by around 1.5% a year. Last week one of the authors of a key United Nations climate report warned that governments are "nowhere near on track" to meeting their commitment, made in Paris three years ago, to avoid global warming of more than 1.5C above pre-industrial levels.When it is unveiled next week, the report from the UN's Intergovernmental Panel on Climate Change (IPCC) will give a clearer idea of the probable consequences of this failure. One recent study suggested the impact of a temperature rise of 2C could be more severe than previously thought, and include sea level rises of six metres by 2100. The relationship between climate change and specific weather events is complex, but modelling suggests global warming made this summer's European heatwave twice as likely. The increased frequency and severity of tropical storms fit with longstanding predictions that warmer oceans will bring more chaotic weather. Continue reading...
