A new report states that human are almost certainly the cause of global warming, reported The Star on Sept. 27. The Intergovernmental Panel on Climate Change released the report that states that limiting climate change will take serious, sustained efforts in reducing greenhouse gas emissions. The New York Times notes that climate officials established a limit the level of greenhouse gasses that can be emitted on Friday.
The panel, sponsored by the UN, presented the 36-page report on Friday. The report states that temperatures will rise by two degree Celsius by the end of the century and sea levels may rise by one meter. The past three decades have been successively warmer than any decade since the 1850s. Heat waves will become longer and more frequent and wetlands will receive more rainfall, while dry regions will receive less. The report went on to state that climate change will affect the poorest countries the most.
The reports states that scientists are 95 percent certain that humans are behind at least half of observed climate changes and have been since the 1950s. This upgrades 2007's assessment that humans were “very likely” to be the cause behind global warming.
The report was no small effort. Eight hundred scientists and input from 1,000 experts were used when creating the full report, which will be released on Monday. Government officials have been 'haggling' with scientists since last Monday over the exact wording of the report.
And the study isn't even over. There are two parts left of this study that will be released in March or April of 2014. These parts of the study will look at the effects of climate change and how to tackle the issue. This upcoming section will likely take thousands of pages.
The Star notes that this report comes out every six to seven years. Once the report is published it is considered the authority on climate science and is a guide for worldwide guide on emissions.
