Humanity must radically change its diet and give up petrol cars in just 12 years in order to save itself from climate change.
That’s according to a damning new UN report, which claims our way of life must change drastically to avoid a plague of droughts, heavy flooding and extreme heat.
Scientists called for humanity to cut how much meat it eats and get rid of all gas boilers in order to stop global temperatures rising 1.5C by 2030.
Other ‘unprecedented’ changes put forward by the team include switching to electric cars and planting extensive forests to absorb CO2 from the atmosphere.
Millions of square kilometres of land would need to be turned into forest or used for growing crops for biofuels – which could undermine food production.
By 2050, humanity must almost completely cut its use of coal as fuel and use renewable energy sources to provide at least 85 per cent of global electricity.
Preventing an extra single degree of heat could make a life-or-death difference in the next few decades for millions of people leaving in coastal areas, scientists said.
Limiting global warming to 1.5C will cost the world $2.4 trillion (£1.8 trillion) every year for the next two decades, the UN report warned.
The landmark report released Monday by the UN has warned that the world has just 12 years to halt global warming before the planet is plunged into extreme heat, drought, floods and poverty.
It found that:
- Burning of coal needs to fall from 38 per cent to ‘close to 0 per cent’ by 2050
- Renewables need to provide 85 per cent of global electricity by 2050
- We need a radical change in diet as eating meat makes more CO2 than vegetables
- Extensive planting of forests will be needed to absorb CO2 from the atmosphere
- Need to start storing carbon underground, known as bioenergy and carbon capture and storage (Beccs)
