まとめ
影の経済は環境の質と生物多様性を損なう. 緑のイノベーションと環境課税を統合することで 二酸化炭素の排出量を軽減できますが G7諸国の持続可能性への移行には 影の経済に対処する必要があります
科学分野:
- 環境経済学
- 経済学
- 気候政策
- 生物多様性の保全
- 機械学習の応用
背景:
- 影の経済は,気候変動と生物多様性政策の効果的な実施に重大な課題をもたらします.
- 非公式な経済活動,財政政策,技術の進歩の相互作用が 持続可能性への移行に重大な影響を及ぼします.
- 現存する研究では 影の経済が環境の悪化や政策の成果に及ぼす影響が しばしば見過ごされている.
研究 の 目的:
- 環境政策における影の経済の役割を分析するために,エコノメトリクスとディープラーニングモデルを組み合わせた統合された枠組みを開発する.
- G7諸国の二酸化炭素排出量と生物多様性に対する影の経済,環境税,グリーンイノベーションの影響を調査する (1994-2020).
- 脱炭素化と生物多様性の保全のための将来の傾向と政策の影響を予測する.
主な方法:
- 横断的に自己回帰的分布式遅延 (CS-ARDL) と完全修正普通最小二乗 (FMOLS) を用いたエコノメトリック分析による関係推定.
- 長期短期記憶 (LSTM) とコンボリューションニューラルネットワーク (CNN) を含むディープラーニングモデルの応用,定量化および予測.
- 1994年から2020年までのG7諸国のパネルデータを活用した.
主要な成果:
- 影の経済は環境の悪化に大きく貢献していることが実証されています.
- 緑のイノベーションと環境課税の実施は,CO2排出量削減と生物多様性の増強に積極的な影響を及ぼしています.
- 2030年までの予測では,影の経済を抑制し,グリーンイノベーションを推進しないことで,脱炭素化が阻害され,生物多様性の喪失が悪化すると示唆されています.
結論:
- 統合された政策戦略は,影の経済に対処し,同時に環境の持続可能性を促進するために不可欠です.
- 効果的な環境課税とグリーンイノベーションへの投資は,気候と生物多様性の目標の達成に不可欠です.
- この研究は,G7諸国の経済非公式化,財政政策,技術的進歩,環境的成果の相互関係を強調しています.

Global Climate Change

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.

Threats to Biodiversity

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...

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.

The Carbon Cycle
39.6K
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.

Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...
