Question

1. Which of the following is a source of uncertainty in future climate projections that we will not be able to reduce?

Question 1 options:

Internal climate variability

Future fossil fuel emissions

Representation of physical processes in climate models, leading to multi-model spread

2,  

Why do we have scenario uncertainty in climate model projections?

Question 2 options:

We don't know how climate will respond to enhanced greenhouse gas forcing in the future.

We don't currently know the magnitude of future global emissions.

All climate models are based on certain physical assumptions and simplifications relative to the real world, introducing uncertainties into projections.

Internal climate variability introduces uncertainty into climate projections.

3.  

By how much is the global temperature expected to rise over the next century?

Question 3 options:

0 degrees C

1 to 6 degrees C

0 to 1 degree C

7 to 8 degrees C

4.  

What subjects do the IPCC reports address?

Question 4 options:

Physical climate science

Adaptation to climate change

Mitigation of climate change

All of the above

None of the above

5,  

According to the 2013 AR5 IPCC report, it is __________ that human influence has been the dominant cause of the observed warming since the mid-20th century.

Question 6 options:

extremely unlikely

unlikely

as likely as not

extremely likely

Internal climate variability

Future fossil fuel emissions

Representation of physical processes in climate models, leading to multi-model spread
