    1. Due to the issues raised above, the current literature involves two different approaches to climate policy design.15 One approach looks at the expected costs and benefits of increasingly stringent penalties on emissions, and then prescribes a policy that equates the marginal benefits (in terms of avoided future climate change damage) with the marginal costs (in terms of forfeited economic output). This is the approach of theorists such as William Nordhaus, and it results in a “policy ramp” where the equilibrium path involves only modest emission cutbacks in early decades, so that the weaning away from fossil fuels is much more gradual compared to other proposals.16 This “ramp” occurs because distant climate damages are heavily discounted for the first few decades, and because of technological improvement over time, which makes emission reductions relatively cheaper if they are postponed.

      Annotation #3:This passage changed my perspective on climate policy by introducing the concept of a "policy ramp," where emissions reductions happen gradually rather than immediately. I had always thought that effective climate action required rapid and drastic cuts to fossil fuel use, but this passage suggests that a gradual transition may be more economically and politically feasible. The idea that climate damages are "heavily discounted" in early decades and that technological advancements will make future reductions cheaper is a perspective I hadn’t considered before. This insight reshapes how I think about climate strategies—not just as urgent, but as long-term processes that require balancing economic growth and environmental sustainability.

      This connects to today's inquiry question—How does economic growth affect the environment?—because it highlights how economic concerns often delay aggressive climate policies to avoid short-term economic downturns. While immediate emissions reductions could significantly benefit the environment, they may also harm economic stability, making governments and industries more reluctant to act. Instead, this "policy ramp" approach suggests that delaying major cuts while investing in cleaner technologies can make the transition smoother and more effective in the long run.

      A study by Pizer et al. (2018) supports this idea, arguing that gradual carbon pricing and technological innovation can lead to cost-effective climate mitigation without disrupting economic growth. They emphasize that long-term policies should focus on reducing emissions efficiently while maintaining economic stability.

    2. Under ideal conditions, a carbon tax can mimic any cap and trade system. In the real world, transaction costs and various uncertainties cause the two approaches to have relative pros and cons. For example, because the damage from emissions is cumulative and long-term, while the compliance costs from emissions cuts are possibly acute and immediate, a predictable carbon tax might limit environmental damages at a much lower cost than a cap and trade system.7 On the other hand, it is much easier for outsiders to verify whether (say) China is adhering to its annual cap than to verify that it is appropriately taxing firms based on their individual emissions.8

      Annotation #2: This passage raises questions about the effectiveness and practicality of different economic policies aimed at reducing environmental damage. One key question that arises is: Which system—carbon taxes or cap-and-trade—is more effective in balancing economic growth and environmental protection in different countries? Additionally, how do governments ensure compliance with these policies, especially in large economies like China?

      This relates to today's inquiry question—How does economic growth affect the environment?—because it explores the trade-offs between limiting emissions and maintaining economic stability. Policies like carbon taxes and cap-and-trade systems attempt to reduce the negative environmental effects of economic growth, but their effectiveness depends on real-world conditions, such as enforcement challenges and the immediate costs businesses face. Understanding these trade-offs is crucial when evaluating how to promote sustainable economic growth.

    3. The gist of the IPCC AR4 is that human activities4 are leading to increasing atmospheric concentrations of CO2, methane, and other greenhouse gases, which allow sunlight to pass through them but trap some of the lower-frequency infrared radiation that bounces back off the earth. This “enhanced greenhouse effect” leads to global warming, which many scientists and economists warn will have dramatic effects on human well-being over the next several hundred years.

    4. The latest edition of the IPCC’s work is the 2007 Fourth Assessment Report (AR4), which consists of three volumes by different “working groups.”3 The gist of the IPCC AR4 is that human activities4 are leading to increasing atmospheric concentrations of CO2, methane, and other greenhouse gases, which allow sunlight to pass through them but trap some of the lower-frequency infrared radiation that bounces back off the earth. This “enhanced greenhouse effect” leads to global warming, which many scientists and economists warn will have dramatic effects on human well-being over the next several hundred years.

      This passage highlights a key idea: human activities are increasing greenhouse gas emissions, leading to global warming. The author emphasizes that this process, known as the "enhanced greenhouse effect," will have long-term consequences for human well-being. This relates to today's inquiry question—How does economic growth affect the environment?—because economic growth often drives increased industrial activity, energy consumption, and deforestation, all of which contribute to higher CO2 and methane emissions. The passage suggests that while economic expansion can improve human living standards, it also comes with significant environmental costs, particularly through climate change.

    1. Annotation 1: "History illustrates that there is no simple or enduring connection between climate or geography and economic success."

      The authors here are arguing that geographical factors like climate and location do not provide a reliable or enduring explanation for economic success or failure. This emphasises that history demonstrates other factors, like colonisation and political institutions play a much larger role in shaping economic outcomes. While geography may influence certain conditions, it is not the primary factor in explaining economic growth or development.

      Annotation 2: "Though it is not politically correct to articulate in public, many people still maintain that Africans are poor because they lack a good work ethic, still believe in witchcraft and magic, or resist new Western technologies."

      Why do certain negative cultural perceptions persist, despite evidence showing that these beliefs are not the underlying causes of poverty? How will these misunderstandings about different cultures chance in the future, especially if these perceptions have historically shaped policies and economic outcomes?

      Annotation 3: "To understand world inequality we have to understand why some societies are organised in very inefficient and socially undesirable ways. Nations sometimes do manage to adopts efficient instituations and achieve prosperity, but alas, these are the rare cases. Most economists and policymakers have focused on "getting it right,"whole what is really needed is an explanation for why poor nations "get it wrong." Getting it wrong is mostly not about ignorance or culture. As we will show, poor countries are poor because those in power make choices that create poverty. They get it wrong not by mistake or ignorance but on purpose."

      The author is telling us that poverty is often the result of a strategic decision made by elites who benefit from the status quo. This makes me think about the role of politics and power in economic development, rather than focusing purely on economic policies or advice. Corruption and poor governance in certain nations create economic inequality and prevent sustainable growth, strengthening the notion that improving economic growth is not just about providing better economic advice or policies but also addressing the deep rooted political issues that prevent those policies from being implemented effectively. The real challenge lies in political reform and ensuring that those in power are incentivised to act in the interests of economic prosperity for all.
