According to a leaked draft of United Nations report, human activity is causing irreversible and extensive damage to the planet and this catastrophic situation will not be halted unless drastic measures are taken to limit the fossil fuel emissions which cause these climate changes.
Global warming has started impacting all the continents and oceans. Further pollution from green house gasses will increase the possibility of harsh, all-encompassing and permanent impacts for people and ecosystems.
The UN Intergovernmental Panel on Climate Change said in the draft, “Without additional mitigation, and even with adaptation, warming by the end of the 21st century will lead to high to very high risk of severe, widespread, and irreversible impacts globally,”.
The study by the UN is a summary of hundred of scientific papers and has been drafted in a way to present the best scientific and economic analysis to government leaders and policymakers worldwide. It will be the most important document which will serve as a beacon to the UN-led effort drawing in more than 190 nations for an agreement on limiting emissions.
IPCC Chairman Rajendra Pachauri said in a statement from the panel’s office in Geneva, “The report will provide policymakers with a scientific foundation to tackle the challenge of climate change. It would help governments and other stakeholders work together at various levels, including a new international agreement to limit climate change that countries intend to broker by the end of next year. ”
The draft which was obtained by Bloomberg from an unnamed official was revised line by line different governments around the world and is scheduled to be published on November 2 in Copenhagen.
A global warming of 4.5 degrees Fahrenheit above the pre industrial levels can cause economic losses equivalent t 2% of the global income. Temperatures have already increased by 0.85 degree since 1880. The temperature increase has happened more quickly than the shift in the climate that ended the last ice age almost 10000 years ago.
