Answers
1
Why might inland agricultural areas be particularly at risk?
Sea level rise
Higher projected temperatures and drought
Greater frost events
More rainfall
2
Which likelihood rating indicates a 66–100% probability?
About as likely as not
Virtually certain
Likely
Very low
3
What is the IPCC’s term for 95–100% likelihood?
Virtually certain
Extremely likely
Very Likely
Likely
4
The IPCC uses “Very High” confidence when:
Only regional data is available
Evidence is anecdotal
Outcomes are unpredictable
Evidence is strong and agreed upon
5
What is “confidence” based on in climate projections?
strength of evidence and agreement
scientists are certain it will happen
there is little evidence
which country it is from
6
What type of data is collected from tide gauges and satellites?
Sea level measurements
Soil salinity levels
Aquifer capacity
Carbon isotope ratios
7
Likelihood is the chance something will happen.
True
False
8
What can warmer and drier conditions lead to in agriculture?
Reduced crop yields
More pollinators
Shorter droughts
Increased soil fertility
9
A rise of over 2°C in global temperatures could cause:
Universal agricultural gains
Irreversible damage to ecosystems
Elimination of climate risks
Slight seasonal changes only
10
What is a likely impact of warmer temperatures on exotic species?
Expansion into new regions
Decreased reproductive success in native species
Extinction of native predators
Stronger immune systems in native species
11
Why do mismatches between flowering and pollinators occur?
Pollinators go extinct each year
Plants stop flowering
Flowers open only at night
Climate change shifts flowering earlier than pollinator activity
12
What does “modelling” in climate science involve?
Drawing weather maps
Using equations to simulate future climate scenarios
Making climate videos
Planting model ecosystems
13
What does IPCC stand for?
International Panel on Climate Control
Integrated Policy for Climate Coordination
International Protocol on Climate Control
Intergovernmental Panel on Climate Change
14
Which of the following is a
direct
measurement used to assess climate variability?
Future crop models
Satellite temperature data
Confidence rating
Emissions scenarios
15
What are climate models most useful for?
Analysing fossils
Forecasting long-term climate trends
Measuring ocean pH
Predicting tomorrow’s weather
16
What is the main cause of sea level rise?
Melting glaciers and thermal expansion
Tectonic uplift
River flooding
Subduction zones
17
What is a phenological change in response to climate change?
Loss of exotic species due to climate
Change in timing of biological events like flowering related to climate
Increased sea levels due to thermal expansion
the study of the size and shape of the cranium
18
Which Australian region may benefit agriculturally from milder winters?
Central Australia
c) Tasmania
Northern Territory
Perth CBD
19
Why is fossil pollen useful to climate scientists?
It shows animal diets
It helps reconstruct past climate and vegetation
It stores carbon
It’s easy to carbon-date
