For the model in fig. 8.3, the value at = 0.9 yields a temperature t=295 k assuming latex: e_s=235\: \mathrm{w}\: \mathrm{m^{-2}}

(a) calculate the value of at that would increase t by 4latex: ^\circ∘c .

(b) assuming this change in at is driven by increases in atmospheric co2, describe the changes we would see in fig. 7.1b (referring to case ii) and fig. 7.2 referring to wavelengths around 15 latex: \mu m

What is an additional type of erosion found at the coast? what does it mean?

From where does the solar winds generate

Although china’s total economic output, measured by gross domestic product (gdp), is third largest in the world, it is considered a developing nation. what is most likely the most important factor for this designation? a. china’s government spends money on things that do not benefit human development. b. china has a large population, so its gdp per person is only modest. c. china has a strong economy but weak literacy and school attendance rates. d. china’s high rates of disease offset the country's economic gains.
