Briefing: Aviation and Climate Change
Climate change is happening. Global average temperatures have already increased by 0.8ºC above preindustrial levels. Current trends imply a warming of 2.9-5.2ºC by the end of the century, which, even at the low end of the range, will cause great impacts on the planet and threaten many areas of human life, including health, food security, economic growth, societal change, and drinking water. 2015 is a key year for global efforts to combat climate change and keep warming under 2ºC, the warming limit agreed in the UN Framework Convention on Climate Change negotiations.
