Data.GISS: GISS Surface Te > hp/registration/reg.courses.php?&lang-en; Question 8: Camp and Tung (2007) found a small warming signal of 0.18°C in atmospheric temperature attributable to the 11-year solar cycle, after removing the long term global warming trend. This proves that solar cycle variations are responsible for the continuing increase in global temperature over the past several decades. true false Question 9: Variations in the eccentricity of Earth's orbit, with a cycle of-100,000 years, leads to slight changes in the intensity of radiation from the Sun that reaches Earth solar activity sunspots Earth's tilt the precession of Earth's axis Question 10: Due to variations in the eccentricity of Earth's orbit, radiation from the Sun is ~23% greater at perihelion than at aphelion. true false Question 11: Variations in Earth's axial tilt and precession both change which can have a significant impact on energy absorbed by the planet position relative to one another the distance of the planet from the Sun the intensity of radiation emitted by the Sun the orientation of the planet relative to the Sun the rate of plate tectonics erExplanation / Answer
8. true, tung and camp found the high correlation between the global warmin and solar cycle.
9. the precession of earth's axis.
10. true.
11. position relative to one another.
12. our next ice age should began in about 100,000 years.
13. 70%
14. about 100 years.
15. true.
16. true.
17. 23 times
18. clouds reflect back energy to the space, leading to cooling as well as holding energy near the surface, leading to warming.
19. positive feedback cycle, increased, increased, decreased, increased.
20. absorb incident solar radiation and cool the troposphere.
