  • How much oil is removed from Earth’s crust?
  • Sentavio/Shutterstock Between 2007 and 2017, 45.5 billion tonnes of oil and 36.3 billion cubic metres of natural gas were removed from the Earth’s crust. When oil and gas is extracted, the voids fill with water, which is a less effective insulator.
  • What happens if oil is removed from the Earth’s crust?
  • Between 2007 and 2017, 45.5 billion tonnes of oil and 36.3 billion cubic metres of natural gas were removed from the Earth’s crust. When oil and gas is extracted, the voids fill with water, which is a less effective insulator. This means more heat from the Earth’s interior can be conducted to the surface, causing the land and the ocean to warm.
  • Is fossil fuel extraction a problem in Antarctica?
  • From 2007, more than 400 oil and gas fields have been developed north of the Arctic circle, while in Antarctica, fossil fuel extraction is banned. An earlier study found evidence for a similar pattern in the north east of England, where a long history of coal mining has dramatically changed the land’s subsurface.
  • What is crude oil?
  • Crude oil is a liquid mixture of substances in the upper earth’s crust, which consists in particular of hydrocarbons and also contains dissolved portions of gas (natural gas) and is the result of the conversion of organic substances (Murawski and Meyer 2004 ).
