Scientists warned that billions of people could be forced to endure 'unliveable' circumstances by 2070 if decisive action is not taken to halt climate change.
Three billion people could live in places as hot as the Sahara desert within 50 years, the World Economic Forum said on Wednesday.
A research team made up of experts from the U.S., China and Europe analyzed rising global temperatures, comparing them to average climatic conditions over the last 6,000 years. TheirUnless moves were made to reverse the damage wreaked on the environment by greenhouse gases, one in three people could live in areas where temperatures matched the hottest parts of the Sahara today, according to the scientific study.
"The crops, livestock and irrigation that are the bedrock of the planet's food production system were developed, discovered and designed within those constraints," the WEF's Sean Fleming said in. "These, and other critical systems, cannot be expected to function normally outside the environmental niche they grew up in."
