Sounding the climate change alarm e warned ~ climate change will affect the way we live. This is the harsh reality painted by the Intergovernmental Panei on Climate Change (IPCC), a United Nations research body that studies the effects of human activity on the world’s weather patterns. Over the years, as the effects of global warming have become increasingly clear, scientists have presented theories about how a rise in global average temperatures could change the face of the world. While some of those changes may take a long time to happen themselves, many seem to promise more sudden and quite dramatic effects. As a result, the panel is now warning governments about the dangers and what to expect. For example, the report predicts a general reduction in potential crop yields in tropical and sub-tropical regions. In many water-scarce regions, the availability of water is éxpected to decrease further, particularly in the sub-tropics. 2.1 Explain your understanding of climate change. 2.2 What does the acronym IPCC stand for? in other regions, more people will be exposed to diseases such as malaria. Deaths caused by too much heat are expected to increase. Then there is the issue of flooding and a rise in sea levels, increasing the risk for coastal areas and flood plains, © home to tens of millions of people all over the world, Higher summer temperatures would also jead to a greater demand for energy as people increase their use of cooling systems, .
