QESOSA Tong Kwok Wah Secondary School Changing climate, changing environments Name: Unit 11.4 2014-2015 S3 Geography ( ) S.3( ) What are the effects of climate change? Key Questions: 1. What are the harmful effects of climate change? 2. What are the possible benefits of climate change? Preparatory task Find out the meaning of the BOLD words. Write down the definition in Chinese in the boxes below. Passage A 1. Global warming may bring benefits to some people and places. Below are some examples. Shorter and warmer winters save more energy in cold areas. The number of deaths caused by cold weather will drop. (1) Crop yields may increase with a lengthened (2) growing season and a longer (3) frost-free period. Shorter shipping routes and make (4) oil drilling easier for the countries around (5) the Arctic Circle. The problem of (6) water shortages will be eased. 2. However, there are harmful effects brought by global warming. For example, Melting ice at the Poles increases the (7) sea levels. More climatic hazards such as flooding, drought, (8) heat waves, wildfires, stronger typhoons and (9) blizzards can be found. (10) Spread of disease such as locust is very common. (11) Extinction of species such as polar bear and coral can be found. (12) Disruption of crop yields and food supply will also be found.
