The world has just five years to avoid being trapped in a scenario of perilous climate change and extreme weather events, the International Energy Agency (IEA) warned on Wednesday.

"The door to 2.0 C is closing," it said, referring to the 2.0 Celsius (3.6 Fahrenheit) cap on global warming widely accepted by scientists and governments as the ceiling for averting unmanageable climate damage.

The report forecasts a one-third jump in primary energy demand by 2035, with 90 percent of this growth in developing economies.
