Question
1) How do scientists attempt to answer questions about future climate?
They don’t
They take a guess
They use models run by super computers
They look for a time when the event happened previously
2) Why will it take time for Earth’s climate system to recover from CO2 already being put into the atmosphere?
There is no way to stop CO2 emissions
CO2 has a short lifetime
CO2 has a long lifetime
None of the above
3) A map on which mean values of temperature and/or precipitation are plotted would be an example of _____ model.
mumerical
conceptual
graphical
physical
4) In order to map ECVs, global climate models do which of the following first?
Compute ECVs for every point
Break the map into a gridded coordinate that includes only the ocean
Break the map into a gridded coordinate that includes only the atmosphere
Break the map into a gridded coordinate that includes both the atmosphere and the ocean
5) Which of the following best describes how climate models predict over a long time scale without losing accuracy?
They are driven by feedbacks that do no influence the weather
They predict how climate adjusts to different conditions
They focus on specific broad regions of positive and negative anomalies
All of the above
6) What must scientists do to ensure model output is better?
Reduce errors
Overcome uncertainty
Use more input data
Both a and b are correct.
7) In a transient model run, how is CO2 added?
Slowly
All at once
It depends on the scientist generating the run
None of the above
8) In an equilibrium run, how long is the model output observed?
Moment to moment for a set period of time
Until the model reaches a new equilibrium
It depends on the scientists generating the run
None of the above
9) Which of the following is true about the PETM, making it the best geological analog for future ocean and biological responses?
Widespread warming associated with large buildup of CO2 and methane
Oceans acidified
Global temps rose several degrees
All of the above
10) Why will all locations on the globe not see the increase in temperatures predicted by climate models?
Climate change is geographically non-uniform in both magnitude and sign
The greatest change will always be seen at the equator, regardless of the forcing mechanism
Climate change is only uniform along lines of latitude
None of the above
11) What does the complex nature of removing CO2 from the atmosphere mean in terms of global climate change?
There is no hope of reversing the changes already made
Making a change will require a serious and prolonged commitment to reducing emissions
There will still be warming even after emissions are reduced, possible for decade to centuries
Both b and c are correct.
12) Which of the following is the hardest area to accurately model?
Temperatures
Precipitation
Clouds
All of the above
None of the above
13) Which tornadoes are the most destructive?
Short-duration storms
Long duration storms
Multi-vortex storms
None of the above
14) Who developed the tornado rating scale?
Saffir Simpson
Fujita
Newton
None of the above
15) When are tornadoes most likely to occur during the day?
In the early morning
In the late evening
Between 10am and 6pm
None of the above
16) What is the general relationship between heavy precipitation events and climate change?
As temperature warms, more frequent heavy precipitation events occur
As temperature warms, less frequent heavy precipitation events occur
As temperature warms, more frequent small precipitation events occur
None of the above
17) What variable is primarily used to rate hurricanes?
SST
Wind Speed
Size
Surge
18) In which basin has a trend been identified in terms of storm development?
Tropical North Atlantic
Tropical Pacific
Indian
Arctic
19) What has been the general trend in terms of snow and ice storms?
There has been a decreased frequency in extreme events
There has been an increased frequency in extreme events
There has been no change in frequency
There have been changes in location only
20) Which of the following could be considered to be a singularity?
Indian Summer
January Thaw
Change in SST
Both a and b are correct.
Explanation / Answer
1)Scientists look in past when that happen might have occurred and according to that they answer questions. It is much real liable as it is much practically to answer questions like this.
2)It will be near impossible task to remove CO2 from Earth’s climate system which is already being put into the atmosphere as 65% and 80% of CO2 released into the air dissolves into the ocean over a period of 20–200 years
3)A map on which mean values of temperature and/or precipitation are plotted would be an example of numerical type as it is the isohyet map in which lines are connects points that have the same amounts of precipitation in a given period or for a particular storm.
