Exercise 1
Result
1 of 1
Global average temperatures rising, ice caps melting, sea levels rising, organisms going extinct, organisms migrating, organisms evolving
Exercise 2
Result
1 of 1
Cow farms, car emissions, industrial pollution
Exercise 3
Result
1 of 1
The burning of fossil fuels produces carbon dioxide, which is a greenhouse gas
Exercise 4
Result
1 of 1
Electricity production, heat homes, power vehicles
Exercise 5
Result
1 of 1
Methane, nitrous oxide, sulfurous oxide
Exercise 6
Step 1
1 of 4
a) a carbon sink is a region where organisms use lots of carbon dioxide to perform life functions
Step 2
2 of 4
b) A forest is an example of a carbon sink
Step 3
3 of 4
c) Carbon sinks are important in reducing the amount of carbon dioxide greenhouse gases emitted into the atmosphere
Result
4 of 4
a) a carbon sink is a region where organisms use lots of carbon dioxide to perform life functions
Exercise 7
Result
1 of 1
Factors include amount of trees, deforestation, insect infestation, and wildfires.
Exercise 8
Result
1 of 1
Humans lead to increased production of greenhouse gases, which lead to increases in temperature, thus climate change
Exercise 9
Result
1 of 1
As more fossil fuels are burned to power vehicles for transportation, Earth’s average global temperature increases. This is due to the emission of greenhouse gases from the chemical reaction that occurs when the fuel is burned
Exercise 10
Step 1
1 of 3
a) Anthropogenic is due to human activity, where natural is everything else
Step 2
2 of 3
b) It is a problem because humans do not care and the rate of climate change caused may destroy the Earth and it may never recover
Result
3 of 3
a) Anthropogenic is due to human activity, where natural is everything else
Exercise 11
Step 1
1 of 4
a) as ocean temperatures rise, ice melts and this melted ice lowers the temperature of the ocean.
Step 2
2 of 4
b) Dry soils from high temperatures allow for increased emissions of greenhouse gas, further increasing the temperature.
Step 3
3 of 4
c) If the temperature of the ocean increases and less carbon dioxide can be absorbed by the ocean, then more carbon dioxide will enter the atmosphere and further raise temperatures
Result
4 of 4
a) as ocean temperatures rise, ice melts and this melted ice lowers the temperature of the ocean.
Exercise 12
Step 1
1 of 3
a) It does not necessarily mean one causes the other, but is a good indicator that they may be related. Something else could cause similar trends between the two, such as greenhouse gas emissions, but the two are likely related
Step 2
2 of 3
b) These are likely related since increasing temperatures cause ice caps to melt and the additional water entering the sea increases the sea level
Result
3 of 3
a) It does not necessarily mean one causes the other, but is a good indicator that they may be related. Something else could cause similar trends between the two, such as greenhouse gas emissions, but the two are likely related
Exercise 13
Result
1 of 1
Nitrous oxide may be harmless to people, but it is a greenhouse gas that leads to temperatures increasing and climate change when it enters the atmosphere
Exercise 14
Result
1 of 1
The scientist could compare data between sea level from the past 200 years and carbon dioxide concentrations in the atmosphere from the past 200 years to compare trends of increase and decrease and if the two figures follow similar patterns, the scientist can conclude that they are related
Exercise 15
Step 1
1 of 4
a) Hurricanes, tornadoes, earthquakes, tsunamis, drought
Step 2
2 of 4
b) None of them have positive impacts since they are severe weather conditions or natural disasters
Step 3
3 of 4
c) extreme events have increased in frequency where I live, summers have more frequent and longer lasting droughts, and there are more violent storms
Result
4 of 4
a) Hurricanes, tornadoes, earthquakes, tsunamis, drought
Exercise 16
Step 1
1 of 5
a) The first report has bias that the temperature is not increasing but they do not have data after 2000 and they have not drawn a trend-line for a relevant period of time. The second report draws a proper trend-line showing that temperature is increasing, but needs to think about other factors causing it other than only fossil fuels
Step 2
2 of 5
b) All trend-lines show a positive increase in temperature besides 1940-1970, which shows a slight decrease
Step 3
3 of 5
c) I would interpret the results based off of the where they decided to show the trends, since the first report claims nothing to worry about, yet the average trend over the past 100 years shows an increase. The second report shows a more logical trend to choose when predicting the future
Step 4
4 of 5
d) The yellow line since it factors in more time to show a true trend that models the future more accurately
Result
5 of 5
a) The first report has bias that the temperature is not increasing but they do not have data after 2000 and they have not drawn a trend-line for a relevant period of time. The second report draws a proper trend-line showing that temperature is increasing, but needs to think about other factors causing it other than only fossil fuels
Exercise 17
Step 1
1 of 5
a) No, since the greenhouse effect increases temperature, and the increase in carbon dioxide emissions leads to more of the greenhouse effect, thus higher temperatures
Step 2
2 of 5
b) Learning about the greenhouse effect and different feedback loops prepared me for this concept
Step 3
3 of 5
c) Yes the evidence is convincing when multiple figures show similar trends when data from various time periods are compared
Step 4
4 of 5
d) Research on greenhouse gas emissions and how to reduce them or limit their impact would help me further understand
Result
5 of 5
a) No, since the greenhouse effect increases temperature, and the increase in carbon dioxide emissions leads to more of the greenhouse effect, thus higher temperatures
Exercise 18
Step 1
1 of 5
a) snow cover is decreasing in Canada due to increased temperatures
Step 2
2 of 5
b) snow keeps earth cool by reflecting sunlight or the suns energy instead of absorbing it as much as other ground coverings do.
Step 3
3 of 5
c) A reduction in snow cover will lead to more increase in temperature since more absorptive ground surfaces will be abundant and will absorb more of the sun’s energy
Step 4
4 of 5
d) this is a positive feedback loop since increased temperatures melt snow, which increases energy absorption, which increases temperatures
Result
5 of 5
a) snow cover is decreasing in Canada due to increased temperatures
Exercise 19
Step 1
1 of 5
a) People argue that the climate is always changing and that these temperatures have happened before. They also argue that models used are inaccurate. Lastly, they say that everyone can adapt so it doesn’t matter
Step 2
2 of 5
b) The rates of climate change and temperature increase have never occurred before. Models are created to show that human activity and temperature trends go hand in hand. Plants and animals are going extinct since they can’t keep up with rapid changes to their native habitats
Step 3
3 of 5
c) The findings listed in part b are my own replies, but many climate change experts say things very similar in response to the arguments in part a
Step 4
4 of 5
d) My responses were very similar to the experts, but new information learned would be the statistical evidence that the experts provide from their research
Result
5 of 5
a) People argue that the climate is always changing and that these temperatures have happened before. They also argue that models used are inaccurate. Lastly, they say that everyone can adapt so it doesn’t matter
