Global-warming gases set to rise by 57 percent by 2030

BREAKING EARTH NEWS
A Warning from the International Energy Agency (IEA)
Emissions of greenhouse gases will rise by 57 percent by 2030 compared to current levels, which will increase the Earth's surface temperature by at least three degrees Celsius (5.4 degrees Fahrenheit), the International Energy Agency (IEA) said on Wednesday.

In its annual report on global energy needs, the Paris-based agency projected greenhouse-gas pollution would rise by 1.8 percent annually by 2030 on the basis of projected energy use and current efforts to mitigate emissions.

The IEA saw little chance of reducing this pollution to a stable, safer level any time soon.

It also poured cold water on a scenario outlined earlier this year by the United Nations' main authority on global warming, the Intergovernmental Panel on climate change (IPCC).

The IPCC said that in order to limit the average increase in global temperatures to 2.4 C (4.3 F) -- the most optimistic of any scenario -- the concentration of greenhouse gases would have to stabilise at 450 parts per million (ppm) of carbon dioxide (CO2) in the atmosphere.

To achieve this goal, CO2 emissions would have to peak by 2015 at the latest, then fall by between 50 and 85 percent by 2050, the panel.

But the IEA's World Energy Outlook report saw no peak in emissions before 2020.
