IMF chief Christine Lagarde warns of 'dark future' over climate change

Says if we don't address climate change then we will be moving to a 'dark future' in 50 years

The world faces a "dark future" if it fails to tackle climate change and inequality, IMF managing director Christine Lagarde warned today.

"If we don't address these issues... we will be moving to a dark future" in 50 years, she told a major economic conference in the Saudi capital.

On climate change, Lagarde said that "we will be toasted, roasted and grilled" if the world fails to take "critical decisions" on the issue.

In 2015, around 195 nations signed the Paris climate agreement which set measures to reduce greenhouse gas emissions to prevent temperatures rising by more than two degrees in around 50 years.

But US President Donald Trump announced in June the start of a three-year process to pull out of the pact, arguing that it would put the US at an economic disadvantage.

His move faced fierce criticism from world leaders and activists, with former UN secretary general Ban Ki-moon accusing Trump of "standing on the wrong side of history".

Lagarde also called for tackling inequality between men and women and countries that are "haves" and those that are "have nots".

If the world wants a future that "looks like utopia and not dystopia", it needs to address such concerns, Lagarde said.

She predicted that in 50 years' time, oil will be a secondary commodity.
