Question

Q. Consider the following:

Which of the above events are the most likely impacts due to climate change?

• A. 1, 2 and 3 only
• B. 1, 2 and 5 only
• C. 2, 3, 4 and 5 only
• D. 1, 2, 3, 4 and 5

Answer 1

The correct option is D 1, 2, 3, 4 and 5

Explanation:

• All of the above events are possible impacts of climate change. Apart from these, there are other impacts as well such as ice calving, rise in sea level, floods and droughts, forest fires, diseases etc.
• Researchers have pointed out that global temperatures will continue to rise for decades to come, majorly due to GHGs produced by anthropogenic activities. The Intergovernmental Panel on Climate Change (IPCC), which includes thousands of scientists from around the globe, predicts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.
• The IPCC forecasts that increases in global mean temperature of less than 1.8 to 5.4 degrees Fahrenheit (1 to 3 degrees Celsius) above 1990 levels will generate beneficial impacts in some regions and harmful ones in others. Net annual costs will increase over time as global temperatures increase.
