The world's 50 biggest oil companies are poised to flood markets with an additional 7m barrels per day over the next decade, despite warnings from scientists that this will push global heating towards catastrophic levels.

New research commissioned by the Guardian forecasts Shell and ExxonMobil will be among the leaders with a projected production increase of more than 35% between 2018 and 2030 - a sharper rise than over the previous 12 years.
