Adapt or Perish in Climate Change: Historical Responsibility and the Global North-South Divide

 Historical Responsibility and the Global North-South Divide

Global North-South Divide

One of the most contentious aspects of climate justice is the historical responsibility of developed nations, primarily in the Global North, for driving climate change through industrialization. Historical responsibility is a legacy that divides the Global North and South, with the latter disproportionately bearing the negative consequences of climate change despite contributing the least emissions they contribute to global warming. This subtopic studies the origins of this division, the ethical debates surrounding historical responsibility, and the mechanisms proposed to address these injustices.

The Legacy of Industrialization and Historical Emissions

The Industrial Revolution, which started in the late 18th century, was a turning point in history, enabling unprecedented economic progress and technological advancement. The crucial part of the revolution was the birth of large-scale exploitation of fossil fuels, which led to the accumulation of greenhouse gases in the atmosphere. Developed nations, including the United States, the United Kingdom, and Germany, were the first to industrialize and are thus responsible for most historical carbon emissions.

According to the Carbon Brief (2019), 23 rich nations have been responsible for half of all historical CO₂ emissions since 1850.

According to reports, the United States accounts for nearly 25% of the total, while the European Union contributes approximately 22% of these climate change-causing gas emissions. It is a consensus that these emissions enabled these now-developed nations to achieve massive economic growth and technological advancement, but at a substantial environmental and social cost now being felt globally.

In contrast, many developing countries, particularly in Africa, Asia, and Latin America, industrialized later or have yet to industrialize fully. Their cumulative emissions are relatively low, but they are the most vulnerable to climate change impacts due to geographic, economic, and infrastructural factors.

The Global North-South Divide

The climate responsibility and vulnerability divide between the Global North and Global South starkly intensifies the vast disparities between nations. Bangladesh, Haiti, Ethiopia, and other countries in the Global South account for less than 4% of global emissions yet face hurricanes, droughts, floods, and other climate-related disasters. This imbalance is evident across several dimensions:

Economically, developed nations positioned themselves to invest in climate adaptation and mitigation strategies as they historically grow their economies and develop infrastructure relying on fossil fuels. In contrast, many developing nations lack the necessary financial resources to appropriately respond to the devastating impacts of climate change, making them more vulnerable to environmental disasters.

Regarding technology, the Global North has more access to advanced renewable energy solutions and disaster management tools. However, the transfer of advanced technology to the Global South is very limited, thus worsening the divide and leaving developing countries ill-equipped to combat climate challenges.

Furthermore, institutional capacity is crucial in combating climate change. Developed nations are reaping benefits from their well-established institutions created to manage climate change risks. Conversely, most developing countries have institutions that need support with governance issues, corruption, and inadequate capacity to implement effective climate policies, further aggravating their vulnerability to climate change.

Ethical Arguments for Historical Responsibility

The ethical foundation of historical responsibility in addressing climate change is primarily rooted in the principle of "common but differentiated responsibilities and respective capabilities" (CBDR-RC), as established by the United Nations Framework Convention on Climate Change (UNFCCC).

The CBDR-RC principle acknowledges that all countries are responsible for combating climate change. However, it highlights the idea that developed countries should take the lead because of their historical emissions and stronger capacity to implement solutions.

Central to the discussion of climate justice is the Polluter Pays Principle.

The principle argues that those who have caused environmental harm should be responsible for the costs associated with mitigating and adapting to climate impacts. This principle inarguably holds developed nations accountable for their massive contribution to the problem.

Additionally, wealthier countries have a moral obligation to support vulnerable developing countries that lack the resources crucial to responding to the effects of climate change. The support can be in various forms, such as financial aid, technology transfer, and capacity-building efforts.

Finally, the concept of intergenerational justice underscores that historical emissions have more profound negative impacts that last for centuries, as carbon dioxide and other gases remain in the atmosphere for an extended period. This concept entails that developed nations are responsible for current and future generations facing the consequences of past actions.

Mechanisms to Address the Divide

A number of mechanisms were established to address the Global North-South divide and promote climate justice. The Paris Agreement (2015) outlined climate finance as one key aspect, and it committed developed countries to mobilizing $100 billion annually to support climate action in developing countries. The financial support is intended to fund renewable energy projects, climate-resilient infrastructure, and adaptation strategies. However, the goal of the promise still needs to be met as the annual amount is insufficient given the scale of the impacts of climate change.

The second relevant mechanism is loss and damage funding, which aims to respond to the irreversible impacts of climate change in developing and small island states, such as the loss of livelihoods, properties, and ecosystems. At COP27 in 2022, nations reached an agreement to establish a fund to compensate for the losses and damages of vulnerable nations and rectify historical injustices due to gas emissions.

Additionally, technology transfer plays a vital role in supporting developing countries in transitioning from fossil fuels to low-carbon renewable energy resources. UNFCCC's Technology Mechanism is one initiative that aims to facilitate technology transfer.

Lastly, debt relief is vital for most developing nations burdened by unsustainable debt, which hinders their capacity to invest in climate solutions. Debt-for-climate swaps are one solution that involves forgiving debt in return for commitments to sustainability initiatives. They present a potential pathway to alleviate the financial strain and boost climate action in developing countries.

Challenges in Bridging the Divide

Various challenges persist in bridging the Global-North-South divide despite the mechanisms established. A notable issue is insufficient funding, as climate finance commitments frequently fall short of expectations. Most funds being allocated are loans rather than grants, thereby increasing the debt burden on developing nations. For example, the Green Climate Fund (GCF) allocated approximately $10.3 billion for various climate projects, with a mix of loans and grants; however, the exact figures for loans versus grants can vary by project and over time. For instance, recent reports have shown that a substantial portion of this funding comprises loans, which can increase the financial burden on recipient countries (Green Climate Fund, 2023).

The second challenge relates to accountability and transparency. Ensuring that climate finance is effectively used and reaching the communities that need it most is more complex due to a lack of oversight, which can lead to the misuse of funds intended for climate projects.

Another challenge is political resistance from developed nations, which often hinders progress, especially when recognizing their accountability for historical emissions. This creates fears of potential legal or financial consequences.

Adapt or Perish in Climate Change: The Climate Crisis Unveiled

The Climate Crisis Unveiled

The greenhouse effect is a crucial process that makes Earth habitable.

Overview of the Natural Greenhouse Effect

The greenhouse effect is a crucial process that makes Earth habitable. Without it, the planet's average surface temperature would be a frigid -18°C, which is far too cold to support most life forms (National Aeronautics Space Administration [NASA], 2023). This natural phenomenon occurs when greenhouse gases (GHGs) such as carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and water vapor trap heat in the Earth's atmosphere. These gases function like a blanket, allowing sunlight to enter the atmosphere and warm the surface while preventing some heat from escaping into space. This delicate balance enables the development of the ecosystem and human civilization by maintaining stable temperatures on Earth for thousands of years.

However, this balance is now being disrupted due to anthropogenic activities. Since the Industrial Revolution, humans have accelerated the increased concentration of GHGs in the atmosphere, intensifying the natural greenhouse effect and causing the planet to warm at an unprecedented rate (IPCC, 2021).

Human-Induced Changes to the Greenhouse Effect

The industrial era in the late 18th century represented a significant shift in the composition of the Earth's atmosphere. That era released enormous amounts of CO₂ into the atmosphere using fossil fuels, such as coal, oil, and natural gas, essential for industrial growth. Concurrently, deforestation and alterations in land use diminished the planet's capacity to absorb CO₂, worsening the condition.

By 2022, atmospheric CO₂ concentrations soared to 420 parts per million (ppm), an increase from 280 ppm during pre-industrial times—a rise of 50% (National Oceanic and Atmospheric Administration [NOAA], 2023). Methane, a greenhouse gas (GHG) that is over 25 times more effective than CO₂ at trapping heat over a century, has nearly tripled, primarily due to agriculture, livestock, and energy production activities (United Nations Environment Programme [UNEP], 2022).

Additionally, nitrous oxide (N2O), another significant GHG, mainly originates from the use of fertilizers in agriculture. According to the Intergovernmental Panel on Climate Change (IPCC), nitrous oxide has a GWP (Global Warming Potential) of approximately 298 over 100 years. This means that one ton of N2O emissions has the same effect on warming the atmosphere as 298 tons of CO2.

Around 50% of the nitrous oxide (N2O) emissions produced by human activities worldwide come from farming soils. This percentage has increased since the 1950s, mainly because of synthetic fertilizers. In both managed (like farms) and natural soils, tiny living things called microbes play a significant role in creating N2O. These microbes are responsible for about 70% of all nitrous oxide emissions worldwide (Shang Z. et al., 2019).

Human actions have intensified the greenhouse effect, disturbing the Earth's energy equilibrium. More heat accumulates in the atmosphere than can escape, resulting in a net warming effect. This phenomenon, commonly known as global warming, is a major contributor to the climate challenges we face today.

1.1.3 Scientific Evidence of the Enhanced Greenhouse Effect

The evidence for the intensified greenhouse effect is well-documented and multifaceted. Greenhouse gas (GHG) concentrations have been measured in the atmosphere using modern instruments, and historical levels have been reconstructed through ice-core samples. The samples collected from deep layers of polar ice hold records of atmospheric conditions spanning hundreds of thousands of years, revealing a correlation between elevated GHG concentrations and warmer periods in the history of the Earth (Petit et al., 1999).

Satellite data indicates less heat escaping into space from Earth's atmosphere compared to pre-industrial times (Harries et al., 2001). The energy imbalance is directly attributed to the heightened GHG levels, confirming that humans have a significant impact on the greenhouse effect, according to scientific consensus.

Additionally, the diminishing amount of glaciers, rising sea levels, seawater acidification, and unprecedented physical environmental changes are tangible indicators of the intensified greenhouse effect on Earth's atmosphere. For instance, the Arctic has experienced a reduction of nearly 13% in sea ice per decade since 1979, and global sea levels have increased by over 20 centimeters since the 19th century due to thermal expansion and ice melting (NASA, 2023).

1.1.4 Feedback Loops and Amplification

The enhanced greenhouse effect exacerbates the natural greenhouse effect due to the increasing concentrations of greenhouse gases (GHGs) in the atmosphere, primarily due to human activities, including burning fossil fuels, deforestation, and dirty manufacturing processes. One major concern is the feedback loops that can amplify global warming. Such interactions demonstrate how an initial change can cascade into a series of processes that intensify the original effect, leading to accelerated impacts of climate change (IPCC, 2021).

One notable example is permafrost thawing. The thawing is attributed explicitly to Arctic permafrost melting due to rising temperatures, which triggers ground-stored methane and carbon dioxide (CO₂) and release into the atmosphere, thus further intensifying the greenhouse effect. Research estimates that the thawing permafrost could release between 30 to 120 billion metric tons of carbon by the end of the century, contributing to climate change. Methane, a more potent greenhouse gas, is particularly concerning as it can be released in large quantities during these thawing events (Schuur, E. A., et al.,2015).

Second, the ice-albedo effect contributes to this cycle. The ice-albedo effect is a significant factor contributing to the acceleration of ice melting due to climate change. Estimates suggest that the loss of Arctic sea ice has contributed approximately 50% to 75% of the observed warming in the Arctic region since the late 20th century. Specifically, a study estimates that the change in albedo due to ice loss could lead to an additional warming of about 1°C in the Arctic by mid-century (Screen & Hughes, 2017).

Another critical factor is forest dieback, wherein warming and drought conditions can diminish forests, such as the Amazon, which are vital carbon sinks. As these forests release a massive amount of stored CO₂ into the atmosphere, global warming further accelerates and intensifies, causing other environmental impacts. According to a study published in Nature Climate Change, it is estimated that the decline of forest ecosystems could release up to 5.8 billion metric tons of CO₂ annually, which would significantly exacerbate the effects of climate change (Houghton, R. A., 2021).

Additionally, the Intergovernmental Panel on Climate Change (IPCC) reports that deforestation and forest degradation contribute approximately 10–15% of global greenhouse gas emissions, highlighting the critical role that forest health plays in regulating the climate (IPCC, 2021).
