Based on a leaked UN draft report, climate specializing scientists have already given their conclusion about the rise of temperature and sea levels which could reach up to 9F (5C) and 2 ft 8 inches (82 cm) respectively towards the turn of the century.

The Intergovernmental Panel on Climate Change (IPCC) had also expressed that human activities have caused global warming by 95 percent. Such assessment is the highest one to date given by the UN body. In their previous report back in 2007, the percentage was at 90. Then in 2001 and 1995, the percentage was 66 and 50 respectively.

The recent IPCC report was the first in the series of trio reports for 2013 and 2014. Apparently, it will be subjected to intense scrutiny most probably caused by the erroneous study it made in 2007 falsely predicting that all Himalayan glaciers could melt by the year 2035.

There are almost 200 governments that have conceded to do what they can in limiting global warming to be lower than 3.6F (2C) which is already higher than the pre-industrial period. This has been regarded as a threshold for disaster activities which include more cases of floods, extinctions, droughts, and rising ocean waters that could swamp island nations and coastal regions. As a matter of fact, temperatures have already increased by 1.4F (0.8C) since the Industrial Revolution started.

The report further expresses a high probability that global temperatures will increase by more than 3.6F in the current century. The predicted range of global temperature hike starts from 1F to almost 9F. This is a wider range than what has been forecasted in the 2007 report.

The IPCC will attempt to discuss the reasons why back in 1998, global temperatures have risen on a slower rate even though during that time, greenhouse gas concentrations were said to be at its record high. Perhaps it is caused by the ash spewed by volcanoes thereby blocking the sunlight, a decline in the sun’s heat during the sun’s solar cycle, and the likelihood that climate is less sensitive than expected despite the build-up of carbon dioxide in the air.
