Noticable changes in the Earth's climate such as unusual weather systems, rising ocean levels, and changing temperatures are being attributed to rising carbon dioxide levels.
On 11 December 1997, an international agreement, The Kyoto Protocol, was adopted in Kyoto Japan by the United Nations Framework Convention on Climate Change to set internationally binding emission reduction targets. It set binding obligations on industrialized countries to reduce emissions of greenhouse gases. In December 2012, an amendment to the Kyoto Protocol, "Doha Amendment to the Kyoto Protocol", was adopted. The amendment included a second commitment period for parties to agree on new commitments, a revised list of greenhouse gases to be reported on, and updates on existing articles which would be affected by the new period.
Despite the agreement, global carbon emission have been steadily increasing year to year at an average 2.7 percent for the last 10 years. 2013 and 2012 are projected to be arond 2.2 percent which is slightly lower than the average. Scientists believe that governments should agree to reverse this trend if emissions must fall and limit warming and climate change.
In 2012, the biggest contributors to carbon emissions China (27%), the U.S. (14%), the EU (10%), and India (6%).
Global Carbon Emission at Record 36 Billion Tons
Global emissions of carbon dioxide from burning fossil fuels are set to rise again in 2013, reaching a record high of 36 billion tonnes - according to new figures from the Global Carbon Project, co-led by researchers from the Tyndall Centre for Climate Change Research at the University of East Anglia (UEA).
The 2.1 per cent rise projected for 2013 means global emissions from burning fossil fuel are 61 per cent above 1990 levels, the baseline year for the Kyoto Protocol.
Prof Corinne Le Quéré of the Tyndall Centre for Climate Change Research at the University of East Anglia led the Global Carbon Budget report. She said: "Governments meeting in Warsaw this week need to agree on how to reverse this trend. Emissions must fall substantially and rapidly if we are to limit global climate change to below two degrees. Additional emissions every year cause further warming and climate change."

Alongside the latest Carbon Budget is the launch of the Carbon Atlas - a new online platform showing the world's biggest carbon emitters more clearly than ever before. The Carbon Atlas reveals the biggest carbon emitters of 2012, what is driving the growth in China's emissions, and where the UK is outsourcing its emissions. Users can also compare EU emissions and see which countries are providing the largest environmental services to the rest of the world by removing carbon from the atmosphere.
"We are communicating new science," said Prof Le Quéré. "Everyone can explore their own emissions, and compare them with their neighbouring countries - past, present, and future."
The Global Carbon Budget reveals that the biggest contributors to fossil fuel emissions in 2012 were China (27 per cent), the United States (14 per cent), the European Union (10 per cent), and India (6 per cent). The projected rise for 2013 comes after a similar rise of 2.2 per cent in 2012.
The rise in fossil fuel emissions in 2012 and 2013 was slower compared to the average 2.7 per cent of the past 10 years. Growth rates in CO2 for major emitting countries in 2012 were China (5.9 per cent) and India (7.7 per cent). Meanwhile the United States' emissions declined by 3.7 per cent and Europe declined by 1.8 per cent.
Emissions per person in China matched figures in the EU at 7 tonnes in 2012. The United States is still among the highest emitter per person at 16 tonnes. By comparison people in India produce a carbon footprint of only 1.8 tonnes.
Most emissions are from coal (43 per cent), then oil (33 per cent), gas (18 per cent), cement (5.3 per cent) and gas flaring (0.6 per cent). The growth in coal in 2012 accounted for 54 per cent of the growth in fossil fuel emissions.
CO2 emissions from deforestation and other land-use change added 8 per cent to the emissions from burning fossil fuels. Cumulative emissions of CO2 since 1870 are set to reach 2015 billion tonnes in 2013 – with 70 per cent caused by burning fossil fuels and 30 per cent from deforestation and other land-use changes.
Prof Pierre Friedlingstein from the University of Exeter said: "We have exhausted about 70 per cent of the cumulative emissions that keep global climate change likely below two degrees. In terms of CO2 emissions, we are following the highest climate change scenario of the Intergovernmental Panel on Climate Change released in September."
