The 20 questions
-
Which two gases are increasing and driving global warming?
- hydrogen and helium
- carbon dioxide and methane
- oxygen and nitrogen
- argon and water vapour
-
What is the scientific consensus on global warming based upon?
- Peer-reviewed publications
- Ancient folklore
- Unpublished blogs
- Unchecked opinion
-
Why is evidence about climate change sometimes uncertain?
- complex context
- constant temperatures
- simple variables
- lack of computers
-
What is the main purpose of peer review in science?
- media editing
- checking by experts
- public voting
- governmental censorship
-
What is the trend for carbon dioxide and methane levels in the atmosphere?
- constant
- decreasing
- increasing
- cycling each day
-
What is the general scientific agreement regarding global warming?
- complete disagreement
- total ignorance
- broad agreement
- untested theory
-
Which process removes carbon dioxide from the atmosphere?
- burning fuels
- decomposition
- photosynthesis
- respiration
-
How should a few dissenting papers be viewed against a massive consensus?
- replacing the consensus
- disproving all data
- outweighted by thousands
- hiding the truth
-
Why might data from global systems lead to incomplete evidence?
- zero error
- perfect accuracy
- interacting variables
- fixed parameters
-
What does a rising trend in atmospheric methane indicate?
- constant greenhouse effect
- reduced carbon
- decreasing temperatures
- increasing warming contribution
-
Which graph type best shows atmospheric gas changes over decades?
- bar chart
- scatter plot
- pie chart
- line graph
-
Why must scientific consensus rely on many independent studies?
- reduces single errors
- increases random guess
- complicates simple facts
- speeds up funding
-
What primary factor drives current global warming?
- magnetic poles
- greenhouse gases
- ocean tides
- solar eclipses
-
Why must correlations in complex Earth systems be interpreted carefully?
- simple linear equations
- lack of data points
- constant temperature scales
- many hidden variables
-
Which method best tracks atmospheric composition changes over time?
- single yearly snapshot
- random daily guesses
- computer simulation only
- regular concentration measurements
-
Why is attributing global warming to a single cause difficult?
- identical weather data
- constant solar output
- stable carbon levels
- many interacting factors
-
How do scientific conclusions change as more climate evidence is collected?
- conclusions are revised
- they remain fixed
- data is ignored
- they become invalid
-
What do increasing atmospheric levels of carbon dioxide and methane cause?
- ozone thickening
- global cooling
- global warming
- nitrogen depletion
-
How do scientists handle uncertainty in climate data?
- they quantify uncertainty
- they ignore errors
- they assume perfection
- they discard data
-
What is the basis of the scientific consensus on global warming?
- media opinions
- peer reviewed publications
- untested hypotheses
- single lab tests
