What are some of the reasons why "climate sceptics" dispute the evidence that human activities such as industrial emissions of greenhouse gases and deforestation are bringing potentially dangerous changes to the Earth's climate?
|
1. EVIDENCE THAT THE EARTH'S TEMPERATURE IS GETTING WARMER IS UNCLEAR
|
|
2. IF THE AVERAGE TEMPERATURE WAS RISING, IT HAS NOW STOPPED
|
|
3. THE EARTH HAS BEEN WARMER IN THE RECENT PAST
|
|
4. COMPUTER MODELS ARE NOT RELIABLE
|
|
5. THE ATMOSPHERE IS NOT BEHAVING AS MODELS WOULD PREDICT
|
|
6. CLIMATE IS MAINLY INFLUENCED BY THE SUN
|
7. A CARBON DIOXIDE RISE HAS ALWAYS COME AFTER A TEMPERATURE INCREASE NOT BEFORE
|
8. LONG-TERM DATA ON HURRICANES AND ARCTIC ICE IS TOO POOR TO ASSESS TRENDS
|
|
9. WATER VAPOUR IS THE MAJOR GREENHOUSE GAS; CO2 IS RELATIVELY UNIMPORTANT
|
|
10. PROBLEMS SUCH AS HIV/AIDS AND POVERTY ARE MORE PRESSING THAN CLIMATE CHANGE
