6 Degrees Could Change the World: Worksheet Answers and Beyond

The documentary "6 Degrees Could Change the World" paints a stark picture of our planet's future under varying degrees of global warming. While the documentary itself doesn't offer a traditional worksheet, we can explore the key concepts it presents and answer hypothetical questions that could form the basis of a comprehensive worksheet. This article will delve into the potential impacts of each degree of warming, offering insightful answers and expanding upon the documentary's core message. We'll analyze the scientific basis behind these predictions, discuss potential mitigation strategies, and explore the societal and economic ramifications of inaction.

1 Degree Celsius: A Subtle Shift with Significant Implications

Worksheet Question: Describe the observable effects of a 1-degree Celsius increase in global average temperature.

Answer: A 1-degree Celsius rise might seem insignificant, but it's a crucial tipping point. We're already experiencing some of these effects: more frequent and intense heatwaves, changes in precipitation patterns leading to droughts in some regions and flooding in others, and subtle shifts in the timing of seasons. Glaciers and ice caps begin to melt at an accelerated rate, contributing to rising sea levels. Coral reefs, highly sensitive to even small temperature changes, experience significant bleaching events, threatening their delicate ecosystems. The subtle shifts in weather patterns also disrupt agricultural cycles, potentially impacting food security in vulnerable regions. This degree of warming is not merely a change in numbers; it’s the onset of a domino effect.

Expanding on the Answer: The impact isn't uniform globally. Some regions experience more severe consequences than others, leading to displacement and increased competition for resources. The increased frequency of extreme weather events strains infrastructure and emergency response systems, posing a significant economic burden. The subtle changes act as early warning signs, hinting at the more drastic changes to come.

2 Degrees Celsius: Entering a Zone of Danger

Worksheet Question: What are the major environmental and societal consequences of a 2-degree Celsius increase?

Answer: At 2 degrees Celsius, the changes become considerably more pronounced and impactful. Sea level rise accelerates, threatening coastal communities and infrastructure. Extreme weather events become even more frequent and intense—hurricanes, typhoons, and droughts becoming the new norm. Large-scale ecosystem shifts are observed, with widespread species extinctions and disruptions to biodiversity. Water scarcity becomes a major global crisis, exacerbating conflicts over resources. Agricultural yields are significantly reduced in many regions, leading to food shortages and price hikes. Mass migrations due to climate-related disasters become increasingly likely, straining resources and leading to social unrest.

Expanding on the Answer: The 2-degree mark represents a significant departure from the climate stability experienced over the past millennia. The economic consequences are substantial, encompassing losses from damaged infrastructure, reduced agricultural output, and increased healthcare costs related to heat-related illnesses. The strain on global stability and governance, due to resource scarcity and mass migration, cannot be underestimated.

3 Degrees Celsius: A World Transformed

Worksheet Question: Discuss the cascading effects of a 3-degree Celsius temperature increase on different ecosystems.

Answer: A 3-degree Celsius increase pushes the planet into a drastically altered state. The Arctic ice cap melts significantly, disrupting ocean currents and potentially triggering runaway climate change. Coral reefs are largely destroyed, leading to substantial loss of biodiversity and impacting fisheries. Many regions experience desertification, rendering vast swathes of land uninhabitable. Extreme weather events are so frequent and severe that they frequently overwhelm human adaptation capabilities. Forest fires become commonplace, contributing to air pollution and releasing more greenhouse gases. The Amazon rainforest, a crucial carbon sink, faces significant risk of collapse, further accelerating warming.

Expanding on the Answer: The cascading effects are interconnected and amplified. For example, melting permafrost releases methane, a potent greenhouse gas, further accelerating warming. The loss of biodiversity weakens ecosystems, reducing their resilience to further changes. The interconnectedness of ecosystems means that the impact on one area has repercussions throughout the entire global system.

4 Degrees Celsius: A Climate Catastrophe

Worksheet Question: What are the potential societal consequences of a 4-degree Celsius temperature increase? How might governments and international organizations respond?

Answer: At 4 degrees Celsius, we enter a realm of profound societal disruption. Large coastal areas are inundated, displacing billions of people. Food security is severely compromised, leading to widespread famine and conflict. Water scarcity triggers mass migrations and conflicts over resources. Many regions become uninhabitable due to extreme heat and lack of water. Economic systems collapse under the weight of the crisis. The global order is destabilized as nations struggle to cope with the cascading effects of climate change.

Expanding on the Answer: International cooperation becomes crucial, but the scale of the crisis might overwhelm the capacity of even the most coordinated international efforts. Governments might face unprecedented challenges maintaining social order and providing essential services. The potential for large-scale conflicts over resources is very high. Adaptation strategies become crucial, but at this level of warming, many regions might face insurmountable challenges. The focus shifts from mitigation to survival.

5 Degrees Celsius: Unthinkable Scenarios

Worksheet Question: Explore the potential for irreversible changes in the climate system at a 5-degree Celsius increase.

Answer: A 5-degree Celsius increase pushes the planet into largely uncharted territory. The possibility of irreversible tipping points increases significantly. The Amazon rainforest could collapse, releasing vast amounts of carbon into the atmosphere. The melting of the West Antarctic ice sheet could lead to a catastrophic rise in sea levels, inundating major coastal cities. Ocean acidification becomes severe, threatening marine ecosystems. The planet’s climate system enters a state of unpredictable chaos, with extreme weather events becoming even more violent and unpredictable.

Expanding on the Answer: At this level, human adaptation becomes increasingly difficult, if not impossible, in many regions. The focus shifts from managing the crisis to simply surviving its effects. Large-scale societal collapse is a distinct possibility, with widespread famine, disease, and conflict.

6 Degrees Celsius: A Hostile Planet

Worksheet Question: Describe the potential conditions on Earth with a 6-degree Celsius increase in global average temperature. What are the implications for human civilization?

Answer: A 6-degree Celsius increase paints a picture of a truly hostile planet. Vast swathes of land are rendered uninhabitable due to extreme heat and desertification. Sea levels rise dramatically, submerging coastal regions. Ecosystem collapse is widespread, leading to a massive loss of biodiversity. Extreme weather events are so frequent and powerful that they reshape the landscape. The survival of human civilization is seriously threatened, with large populations facing displacement, starvation, and conflict over dwindling resources.

Expanding on the Answer: This scenario is far beyond the realm of manageable adaptation. Human survival would depend on the availability of resilient communities, technological innovation for survival in extreme environments, and possibly large-scale migration to more habitable regions, though these regions might be extremely limited.

Conclusion: The Urgency of Action

The "6 Degrees Could Change the World" scenario is not a prediction, but rather a stark warning. The future is not predetermined; the level of warming we experience will depend on the actions we take today.
