Exam 21: Climate Change- When the Trees Leave: Scientists Grapple With a Shifting Climate- Alternatives to Fossil Fuels

Infographic 21.5. -Refer to Infographic 21.5. Sulfate aerosols are produced mostly from sulfur dioxide which arises from fossil fuel combustion. Because of their impact on air quality, including its role in acid deposition, efforts to reduce emissions, for example by using scrubbers at coal-fired power plants, have succeeded in lowering emissions. Use the infographic to determine what effect these reductions in emissions would have on climate.

Which of the following is NOT an example of adaptation to climate change?

Since climatologists started keeping records in 1850, the warmest decade globally was:

Deliberately thinning out paper birches in an effort to cultivate more oaks and white pines in Minnesota in light of massive paper birch die-offs is an example of ___________.

Which of the following factors has low albedo and contributes to warming?

What method of measuring atmospheric CO₂ levels gives a more accurate result?

Infographic 21.7. -Refer to Temperature and Atmospheric CO₂ Concentration from the Vostok Ice Core graph in Infographic 21.7. The relationship between temperature and carbon dioxide is complex. Explain the relationship between these two variables (1) as Earth comes out of a glacial period (ice age) and increases in carbon dioxide lag temperature increases by hundreds of years, and (2) in reference to the recent warming over the last hundred years where increased carbon dioxide release is preceding the warming.

The meteorological conditions in a given place on a given day refer to its _________.

The cause of the vast majority of climate change can be attributed to:

Shifts in the ranges of tree species due to climate change are called ________.

List several techniques used by climate scientists to gather indirect data on climate (temperature, carbon dioxide levels, etc.) from the distant past.

How would applying the precautionary principle now to carbon dioxide emissions help to avoid, or at least lessen, some of the more serious outcomes of a changing global climate?

Which of the following are factors that prevent migrating tree species from thriving in their new, more northerly habitats?

Which of the following facilitate mitigation efforts on a national or global scale?

Describe the difference between weather and climate. Provide an example for each.

Which of the following does NOT directly contribute to sea level rise?

Which of the following is TRUE regarding the greenhouse effect?

Which of the following is NOT an example of current or probable benefits from climate change to people in certain places?

-Refer to Infographic 21.8. What is the scientific consensus regarding the cause of the recently observed changes in global climate?

Changes in global climate are predicted to have a negative impact on forests. Forests provide which of the following ecosystem services?
