Answer 17

• 26 April 1986

• The reactor went into meltdown and a cloud of highly radioactive material drifted over much of Russia and Europe, even reaching Wales + Scotland
• Fission products have a long half-life and were accumulated in food chains

Question 18

Case Study: Chernobyl (1986) // impacts

Answer 18

• 31 people died immediately due to radiation
• Some estimates state that 1 million people will have died as a result of the disaster

Question 19

Kyoto Protocol (1997) // what it a success? YES:

Answer 19

• in some countries caused 3% reduction in emissions
• increased governmental + public awareness
• many took actions to reduce greenhouse gas emissions as a household, when travelling and when at work. This means that whilst many governments failed to reach the targets set out by the agreement, individually people were becoming increasingly environmentally friendly

Question 20

Kyoto Protocol (1997) // what it a success? NO:

Answer 20

• Many countries failed to sign up to the agreement or initially signed up and then dropped out e.g when George Bush became president he rejected it on the grounds that it would hurt US economy
• In Russia the Kyoto agreement caused a collapse in the economy
• The Kyoto agreement’s mechanisms created a carbon marketplace where carbon credits could be traded. This allowed richer nations to avoid cutting their emissions, and in some cases, disguise an increase
• Even the original target of 5.5% was too small to make much of an impacts on climate change
