Read the text and answer the questions: - //Climate change: forecast for 2100 is floods and heat ... and it’s man’s faultByNick Allen 9:04 PM BST 16 Aug 2013. > Climate scientists have concluded that temperatures could jump by up to 5°C and sea levels could rise by up to 82cm by the end of the century, according to a leaked draft of a United Nations(UN)report. //The UN Intergovernmental Panel on Climate Change(IPCC)also said there was a 95 per cent likelihood that global warming is causedby human activities. That was the highest assessment so far from the IPCC, which put the figure at 90 per cent in a previous report in 2007, 66 per cent in 2001, and just over 50 per cent in 1995.//Reto Knutti, a professor at the Swiss Federal Institute ofTechnology in Zurich, said: “We have got quite a bit more certain that climate change is largely man-made. We’re less certain than many would hope about the local impacts.” The IPCC report, the first of three in 2013 and 2014, will face intense scrutiny particularly after errors in the 2007 study, which wrongly predicted that all Himalayan glaciers could melt by 2035. //Almost 200 governments have agreed to try to limit global warming to below 2°C above pre-industrial times, which is seen as a threshold for dangerous changes including more droughts, extinctions, floods and rising seas that could swamp coastal regions and island nations. Temperatures have already risen by 0.8°C since the Industrial Revolution.//The report will say there is a high risk global temperatures will rise by more than 2°C this century. They could rise anywhere from about 0.6°C to almost 5°C a wider range at both ends of the scale than predicted in the 2007 report. It will also say evidence of rising sea levels is “unequivocal”. The report projects seas will rise by between 30cm and 82cm by the late 21st century. In 2007 the estimated rise was between 18cm and 58cm, but that did not fully account for changes in Antarctica and Greenland.//Scientists say it is harder to predict local impacts. Drew Shindell, a Nasa scientist, said: “I talk to people in regional power planning. They ask, 'What’s the temperature going to be in this region in the next 20 to 30 years, because that’s where our power grid is?’ We can’t really tell.”(adapted from <telegraph.co.uk> Consider the following statements concerning global warming and the leaked draft of theIPCC report: 1-Scientists think it is 95% likely that human activity is causing global warming. 2- emperatures could be 5°C warmer by the end of the current century. 3-Scientists are surer now than in 2007 that humans are causing global warming.4- Sea levels are not likely to be higher than today by the end of the century. 5- 50% of the scientistsbelieved humans were the cause of climate change in 1995. 1)Which of the statements above are TRUE, according to the text? *

2) Considering what the text says about the IPCC and its predictions and conclusions on global warming, mark true (T) or false (F) for the following statements: ( ) The IPCC made a wrong prediction about the Himalayas in the 2007 report. ( ) Himalayan glaciers will certainly disappear by 2035 because of global warming. ( ) The IPCC can now be sure of how climate change will impact different locations. ( ) IPCC’s new report will be carefully examined after the errors committed in 2007. ( ) Global warming will have a huge impact in Swiss because of its large glaciers. *
