Answer 16

deforestation

Answer 17

awesome thanks
Although the Earth has warmed and cooled many times throughout its history, there is one big difference about the warming trend we’re experiencing now as compared to previous warming episodes. What is this big difference?

The planet is warming much more slowly than previously.
The warming is caused by increases in greenhouse gas emissions.
The rate of change is much greater than in previous warming periods.
The ocean is being impacted by this warming trend.


This warming trend is expected to last for a shorter period of time.

Answer 18

im not sure about this one... i think that its B tho

Answer 19

ok thanks, a few more?

Answer 20

sure

Answer 21

An increase in disease may be a consequence of global warming because…

Many disease vectors require higher sea levels.
Rising sea levels will contaminate freshwater aquifers.
Increased greenhouse gases can cause human illness.
Warming will expand the range of infectious disease vectors.


Decreases in snow and ice cover can release hibernating pests that may cause disease.

Answer 22

Warming will expand the range of infectious disease vectors.
I think.... Im not 100% sure tho

Answer 23

its ok cool thanks and wanted to ask you something?

Answer 24

what?

Answer 25

I have to leave to help my dad, if I post the other 6 questions, will you be willing to answer them?

Answer 26

if im going to be one sure, just tag me

Answer 27

on*

Answer 28

5. Sea level rise is likely to cause…
(Points : 2)
increased costal erosion
damage to current coral reefs
contamination of coastal freshwater aquifers
flooding of low-lying islands


all of the above

Question 6. 6. Which of the below are predicted consequences of global warming?
(Points : 2)
increases in conflicts over scarce resources
decreases in land and sea ice cover
increased drought
increased precipitation


all of the above

Question 7. 7. Which of the statements below is not true of global warming?
(Points : 2)
Sea level changes can lead to changes in ocean circulation patterns.
Rising sea level can contaminate coastal supplies of freshwater.
Increased drought and/or precipitation can cause reductions in food production.
Increased precipitation will alleviate world water problems.


Permafrost in the tundra will melt, releasing greenhouse gases and reducing biodiversity in those regions.

Question 8. 8. Which of the following is an example of carbon capture and storage (CCS) technology?
(Points : 2)
sequestration of carbon in deep sea
removal of CO2 from smokestacks and vehicle emissions
sequestration of carbon in crops or trees
storage in spent coal bed cavern


all of the above

Question 9. 9.

Climate change is difficult to address because…

The problem is regional, not global.
The effects will last a long time.
Problems will be solved by short-term political solutions.
Many of the problems and solutions are controversial.


(Points : 2)
I and II only
I and III only
II and III only
III and IV only


II and IV only

Question 10. 10. Improving energy efficiency is least likely to…
(Points : 2)
reduce the amount of fossil fuels used
prevent some additional ocean acidification
reduce air pollution
reduce CO2 emissions


reduce N2O emissions
