商品詳細介紹Product Introduction

片名:地理工程學–地球工程技術拯救氣候危機
          Geoengineering – Can Technology Save the Climate


探討地球工程學作為應對極端氣候變遷的可能解決方案所帶來的影響和問題,科學家在探索各種地球工程學技術,包括直接空氣捕獲和太陽地球工程等方法,這些技術涉及對自然過程的重大影響,可能會產生長期的未知後果,呼籲人們深入思考氣候變遷因應策略的道德和相應的代價及風險。


如果我們不採取積極努力的措施來保護氣候,我們將無法阻止全球超過《巴黎協定》設定的兩度目標,大多數專家都同意這一點,同時,研究人員正在探討不同的方法,以確保我們仍能達到這一目標。越來越多的技術被討論,可以總稱為「地球工程學」,這些包括被稱為「直接空氣捕獲」的措施,即直接從周圍的空氣中過濾二氧化碳,或者像「太陽地球工程」這樣的過程。第二種方法包括將太陽的光線引開地球,以減緩「溫室效應」,進而減緩全球變暖,在討論的方法中,例如,有一種技術上具有挑戰性的方法,即在太陽和地球之間安裝鏡子,更實際的方法包括讓雲變亮,以增強它們反射陽光進入太空的能力,或讓天空變暗以提供降溫,這是從火山爆發產生的火山灰雲中觀察到的現象。
所有這些過程都涉及對自然過程進行重大干預,其長期後果幾乎難以預見。科學家、環保人士和政治決策者面臨一個困境,地球工程學提供了對極端氣候變化的快速解決方案,這樣做的代價是什麼?
 

If we fail to take drastic measures to protect the climate, we will be unable to keep global warming from exceeding the two degrees Celsius target set in the Paris Agreement. Most experts share this opinion. Meanwhile, researchers are investigating different ways to ensure we are still able to reach the goal. Increasingly, technologies are being discussed that can all be summarized with the term “geoengineering.” These include measures known as “direct air capture,” or the filtering of CO2 right out of the surrounding air, or processes such as “solar geoengineering.” The second method encompasses different ways of steering the sun’s rays away from the earth in order to slow the “greenhouse effect” and with it, global warming. Among the approaches discussed, for example, is a technologically challenging one that would install mirrors between the sun and the earth. More feasible are methods to brighten up the clouds in order to enhance their ability to reflect sunlight into space or darken the skies to provide cooling. This is something that’s been observed in ash clouds that come from volcanic eruptions. 
All these processes involve making significant interventions in natural processes, the long-term consequences of which are barely foreseeable. Scientists, environmentalists and political decision makers are faced with a dilemma. Geoengineering holds out rapid remedies to the extremes of climate change. But at what price?
