The report released by the United Nation’s intergovernmental panel on climate change (IPCC) on 27 September 2013 highlighted that human beings are the main reason for climate change.
It also reported that the carbon accumulation in the atmosphere and resulting global warming have blown away the 2 degree Celsius tipping point that was earlier reported.
To limit warming to a rise of 2 degrees Celsius 1000 gigatons (trillion metric tons) is the outer limit of carbon dioxide that can be emitted. But in 2011 human beings already emitted 531 gigatons. According to climate change experts 1000-gigaton limit may well be crossed in the next 25 years.
According to the report the world has a total of 2795 gigatons worth of carbon in the form of fossil fuels and reserves. Burning just percent of these would take the earth over the tipping point.
The report also presented regarding sea level rise. It highlighted that sea levels are projected to rise by 28-97 centimeters by 2100.This is more than 50 percent of previous projection of 18 to 59 percent over the same period. This increase is mainly because of better estimation methods and more observations. It is projected that seas will be higher by up to a cataclysmic 3 meters by 2300.
About Intergovernmental Panel on Climate Change (IPCC)
• The Intergovernmental Panel on Climate Change (IPCC) is the international body for the assessment of climate change.
• It was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) in 1988.
• In 1988 the UN General Assembly endorsed the action by WMO and UNEP in jointly establishing the IPCC.
• The IPCC is a scientific body under the auspices of the United Nations (UN). It reviews and assesses the most recent scientific, technical and socio-economic information produced worldwide relevant to the understanding of climate change.
• It does not conduct any research nor does it monitor climate related data or parameters.
