1 MUDDIEST POINT

2 Guiding Q

3 READING READINESS QUIZ

4 1. Why is a change of a few degrees in average global temperatures more concerning than day- to-day weather changes of a few degrees? a) This means that temperatures are increasing all around the globe, not just in a few areas. b) Weather changes of a few degrees rarely happen so it is not something we worry about. c) Even a slight increase in average global temperatures means we should have more weather extremes that can cause problems. d) Climate has never changed in the past so if it is changing now by even just a few degrees we know something is wrong.

5 2. How are ice cores used in climate science? a) They are used to cool areas that are warming too quickly. b) Excess CO2 that is removed from the atmosphere can be stored there. c) Scientists set out ice cores and monitor how quickly they melt to get an estimate of the effects of climate change. d) Bubbles trapped in the ice reveal clues about the atmosphere at the time each bubble formed.

6 3. What is the evidence in the North Woods of Minnesota that suggest climate is changing? a) The range of some trees is moving northward. b) Deer have left the area. c) Fewer fires are occurring in what is naturally a fire adapted ecosystem. d) Prairie has replaced the forest along its northern edge.

7 4. Global warming is expected to cause sea level to rise due to a) erosion of coastlines b) the thawing of the permafrost c) the increased flow rate of rivers that will take more water to the oceans of the world d) melting glacier and land-based ice and the thermal expansion of water as it warms

8 5. One of the paths we must follow to address global warming is called mitigation. This is referring to: a) Things that we can do to lessen the potential for future warming b) International agreements to provide money to help poorer nations cope with the change c) Taking steps to adjust to the warming that we have already experienced d) Making preparations to deal with inevitable warming that will come

Why is a change of a few degrees in average global temperatures more concerning than day- to-day weather changes of a few degrees? a) This means that temperatures are increasing all around the globe, not just in a few areas. b) Weather changes of a few degrees rarely happen so it is not something we worry about. c) Even a slight increase in average global temperatures means we should have more weather extremes that can cause problems. d) Climate has never changed in the past so if it is changing now by even just a few degrees we know something is wrong.

11 Global Warming – how it happens

12 2. How are ice cores used in climate science? a) They are used to cool areas that are warming too quickly. b) Excess CO2 that is removed from the atmosphere can be stored there. c) Scientists set out ice cores and monitor how quickly they melt to get an estimate of the effects of climate change. d) Bubbles trapped in the ice reveal clues about the atmosphere at the time each bubble formed.

14 Is Global Warming True?

15 3. What is the evidence in the North Woods of Minnesota that suggest climate is changing? a) The range of some trees is moving northward. b) Deer have left the area. c) Fewer fires are occurring in what is naturally a fire adapted ecosystem. d) Prairie has replaced the forest along its northern edge.

16 WHAT EVIDENCE EXISTS THAT CLIMATE IS ACTUALLY CHANGING?

Global warming is expected to cause sea level to rise due to a) erosion of coastlines b) the thawing of the permafrost c) the increased flow rate of rivers that will take more water to the oceans of the world d) melting glacier and land-based ice and the thermal expansion of water as it warms

This is referring to: a) Things that we can do to lessen the potential for future warming b) International agreements to provide money to help poorer nations cope with the change c) Taking steps to adjust to the warming that we have already experienced d) Making preparations to deal with inevitable warming that will come

24 How it All Ends

25 This unfortunately has become a political issue rather than just a scientific one and that muddies the waters when we are trying to figure out what to do – reduce your own footprint but stay educated on the issue and urge your leaders to do what you think is needed.
