まとめ
世界経済は 排出の選択に関わらず 気候変動の影響で26年以内に19%の収入減少に直面しています 気候変動による損害は 緩和コストを遥かに上回り 緊急の適応の必要性を強調しています
科学分野:
- 気候科学
- 経済学
- 環境科学
背景:
- 気候変動による被害の予測は 長期の平均気温の影響に依存しています
- 40年以上に渡る1600以上の世界の地域から得られた 最近の経験的データから 新たな視点が生まれます
研究 の 目的:
- 極端な気温や降雨の変動による地方経済被害を予測する.
- 将来の排出量とは無関係に短期的な経済的影響を評価する.
- 気候被害と緩和コストを比較する
主な方法:
- 世界中の1600以上の地域から 最近の経験的発見を活用しました
- 経済成長への影響の下限を確立するために経験的アプローチを採用しました.
- 日々の変動と極端な状況を含む,気温と降水に基づいて予測される損傷
主要な成果:
- 世界経済は,将来の排出の選択にかかわらず,26年以内に19%の収入削減を約束しています (可能性範囲は11%から29%です).
- 温暖化を2°Cに 制限するコストの6倍に相当します
- 非常に高い緯度を除くすべての地域が損失を被る見通しで,最も大きな損失は低い緯度にある.
結論:
- 短期的には 気候変動が経済成長に及ぼす影響は 大きく前もって決まっています
- 気候変動による経済的損害は 短期的には 緩和コストを大幅に上回ります
- 気候変動は 低緯度地域と 低所得地域と 過去の排出量地域に 不釣り合いな影響を及ぼしています

Global Climate Change
24.3K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

What is Climate?
18.4K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Energy Budgets
9.2K
Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

The Carbon Cycle
37.4K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Threats to Biodiversity
22.3K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Sustainable Development
13.3K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.
