take off All scientists subscribe agree with to the view that it is human activity that has caused global warming. For example, fossil fuels are consumed used , releasing lotsof of CO 2 into the atmosphere. As a result, quantities more heat energy is possible tends to be trapped, causing the global temperature to increase. go up
