Eviro. Unit 8 lesson 5: Climate Change
How might the solar maximum and minimum influence climate change?
Some scientists believe that the earth cools around the solar minimum and warms around the solar maximum.
Describe what climate information can be found in tree rings.
The width of a tree ring tells how much the tree grew in one year. Knowing the amount of growth can help in determining the amount of precipitation for that year.
Why is the greenhouse effect good?
Without the greenhouse effect, earth would be too cold for survival.
climate change
a long-term change in a region's precipitation and temperature
What is anthropogenic global warming?
the belief that humans are causing global warming
Select the most common greenhouse gases.
-methane -water vapor -nitrous oxide -carbon dioxide
What climate information can scientists deduce about past climates from ice cores?
-temperature -chemistry -biological productivity -precipitation -gas composition -volcanic eruptions -solar variability
Label the diagram.
A: nitrous oxide B: methane C: carbon dioxide D: solar radiation E: reradiated heat F: reemitted heat
How could added greenhouse gases affect global temperatures?
More gases trap more reradiated heat. The trapping of more heat may lead to an increase in global temperatures.
Describe what climate information can be found in sediments.
Pollen grains can tell what types of plants lived at the time the sediment was deposited. Climate can then be inferred based on the types of plants.
anthropogenic
caused by humans
global warming
the rising of the overall global temperature
paleoclimatology
the study of climate throughout all of earth's history
greenhouse effect
the trapping of heat that reradiates from the surface of the earth
