The world plans to produce more than double the amount of coal, oil and gas in 2030 than would be consistent with curbing global warming, the United Nations and research groups said on Wednesday in the latest warning over climate change.

Some of the largest fossil fuel producers in the world, including Australia, China, Canada and the United States, are among those pursuing major expansions in fossil fuel supply.

Under the 2015 Paris Agreement, nations have committed to a long-term goal of limiting average temperature rise to below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit it even further to 1.5 C.
