Question 11 pts

How is climate change affecting precipitation patterns?

Group of answer choiceswe are seeing less rainfall everywhere due to temperatures increasing

we are seeing more rain everywhere due to greater evaporation causing more water vapor in the air

wet places are getting wetted and dry places are getting drier, with more extremes

Flag question: Question 2Question 21 pts

Which of the following is definitely NOT a reason that our climate has changed over the last 100 years?

Group of answer choicesthe ice-albedo positive feedback

Milankovitch cycles (changes in Earth’s orbit)

a change in greenhouse gas concentrations

more aerosols being put into the atmosphere

Flag question: Question 3Question 31 pts

What causes the LARGEST uncertainty in our estimates of future climate changes by 2100?

Group of answer choiceshow quickly ice sheets will respond to rising temperatures

what amount of greenhouse gases humans choose to emit over the coming decades

the response of clouds and precipitation

sudden shifts such as the melting of sea ice or changes to the thermohaline circulation

Flag question: Question 4Question 41 pts

A global increase in temperatures will not be distributed evenly across the Earth – some areas will not warm by much whereas other areas will warm a lot. Where will the greatest increase in temperatures be?

Group of answer choicesthe Arctic

Southern California

tropical areas

mountain regions

Flag question: Question 5Question 51 pts

Would it be a good idea to buy a house near the beach in Florida at a height of just 10cm above sea level?

Group of answer choicesYes

No

Flag question: Question 6Question 61 pts

One proposed idea to prevent climate change is to have a tax on goods and services that produce carbon dioxide. This would likely raise the price of airplane flights and so reduce the number of flights that people take per year. This would be an example of:

Group of answer choicesconservation

efficiency

carbon-free energy

carbon capture and storage

geoengineering

Flag question: Question 7Question 71 pts

Why are geoengineering solutions to climate change, such as space mirrors or ocean fertilization, not necessarily good ideas?

Group of answer choicesMany of them are not yet possible because we don’t have the necessary technology.

Many of them would be much more expensive to implement than simply cutting carbon emissions.

Many of them could have dangerous unintended consequences to ecosystems or weather on Earth.

Many of them would help lower temperatures but would not prevent ocean acidification.

All of the above!

Flag question: Question 8Question 81 pts

One proposal to counter climate change is to plant more trees which would photosynthesize and remove carbon from the atmosphere. We release 5,500,000,000 tons of carbon into the atmosphere each year. A 1 km2 area of growing forest takes up about 400 tons of C per year. How big an area would we have to plant with trees to take up all of our carbon emissions for just one year?

Group of answer choices2200 square km

13,750 square km

13.75 million square km

2.2 billion square km

Flag question: Question 9Question 91 pts

What actions could you personally take to reduce climate change?

Group of answer choiceseat less meat

reduce your consumption of single-use items or fast fashion or electronics

take shorter showers and put on a sweater instead of turning on the heat at home

vote for policies that promote climate action

purchase solar panels or electricity produced using renewable energy when you have your own house

all of the above and more!

Flag question: Question 10Question 101 pts

Which of the following is NOT a question that climate scientists can answer with the scientific method? (In other words, which of these is a moral or ethical question rather than a scientific question?)

Group of answer choicesShould the US government accept refugees from countries that will be impacted by climate changes such as sea level rise?

What is causing our climate to change?

What will our climate be like by 2100 given possible greenhouse gas emissions?

What actions or technologies would be effective at reducing greenhouse gas emissions?

Is our climate changing?
