Global Greenhouse Gas Could Rise 50 Percent By 2050
The Organization for Economic Cooperation and Development (OECD) said on Thursday that global greenhouse gas emissions could rise 50 percent by 2050.
The report said that unless more ambitious climate policies are created, fossils fuels will supply about 85 percent of energy demand in 2050, increasing greenhouse gas emissions by 50 percent.Fossil fuels like oil, coal and gas will make up 85 percent of energy sources by 2050, while renewables are expected to make up just 10 percent.
OECD said because of such a dependence on fossil fuels, carbon dioxide emissions from energy use are expected to grow by 70 percent, driving the global temperature up between about 5.4 and 10.8 degrees Fahrenheit by 2100.
Some estimates say that financial cost of taking no further climate action could result in up to a 14 percent loss in world per capita consumption by 2050.
The OECD also said premature deaths from pollution exposure would double to 3.6 million a year.
According to the report, demand for water could rise by 55 percent, increasing competition for supplies and resulting in 40 percent of the global population living in water-stressed areas.
In order to prevent the prediction laid out by the report, OECD said international climate action should start in 2013, a global carbon market be set up, the energy sector be transformed to low-carbon and all low-cost advanced technologies should be explored.
It said current international pledges to cut emissions fall short of what is required to limit temperature rises to safe levels, so decisive action at the national level is needed.
