10 分 - Global Warming and Global Dimming 對樓宇設計和建築的影響?

發問:

我想探討吓Global Warming and Global Dimming 對樓宇設計和建築的影響?還有對全球的其他影響? 最好係英文, 謝謝. 更新: 主要係想知對樓宇設計和建築的影響? globalization (如將工廠搬去落後或發展中国家)對Global Warming and Global Dimming 的影響?

最佳解答:

Global dimming From Wikipedia, the free encyclopedia Jump to: navigation, search 圖片參考：http://upload.wikimedia.org/wikipedia/en/thumb/8/82/Sfc.contrail.1.26.01.JPG/300px-Sfc.contrail.1.26.01.JPG 圖片參考：http://en.wikipedia.org/skins-1.5/common/images/magnify-clip.png NASA photograph showing aircraft contrails and natural clouds. The temporary disappearance of contrails due to plane groundings after the September 11, 2001 attacks, and the resulting increase in diurnal temperature range gave empirical evidence of the effect of thin ice clouds at the Earth's surface [1]. Global dimming is the gradual reduction in the amount of global hemispherical irradiance (or total solar irradiance) at the Earth's surface, observed since the beginning of systematic measurements in 1950s. The effect varies by location, but worldwide it is of the order of a 4% reduction over the three decades from 1960–1990. This trend has reversed during the past decade. Global dimming creates a cooling effect that may have partially masked the effect of greenhouse gases on global warming.

This means globally reduced evaporation and hence precipitation occur in a dimmer and warmer world, which could ultimately lead to a more humid atmosphere in which it rains less [6]. [edit] Relationship to global warming The phenomenon underlying global dimming may also have regional effects. While most of the earth has warmed, the regions that are downwind from major sources of air pollution (specifically sulfur dioxide emissions) have generally cooled. This may explain the cooling of the eastern US relative to the warming western part [7].
