Global warming is projected to cause significant changes in climate and rainfall patterns across the globe. These shifts have the potential to render densely populated parts of the world uninhabitable and to destroy critical food-growing areas.

Consequences of Global Warming: Shifting Climate Patterns and Threats to Habitability

A small, low-lying island nation in the tropics relies heavily on rain-fed agriculture for its food supply and has a densely populated coastal capital. If global temperatures continue to rise, which of the following scenarios poses the most comprehensive and immediate threat to the nation's long-term habitability?

Analyze and compare the primary threats to long-term habitability and food security for two distinct hypothetical regions facing significant shifts in climate and rainfall patterns: 

1. A densely populated, semi-arid agricultural region that relies almost exclusively on a single, glacier-fed river for irrigation and drinking water. 
2. A low-lying coastal megacity in a tropical zone that is a major hub for international trade. 

In your analysis, identify the different types of challenges each region would face and explain how these challenges are unique to their geographical and economic situations.

Comparative Analysis of Climate Change Impacts

Based on the provided scenario, analyze two distinct ways these projected changes in climate patterns could threaten the long-term viability of the region's agricultural industry and the habitability of its communities.

Analyzing Climate Impact on an Agricultural Region

Explain how a significant, long-term shift in rainfall patterns in a major agricultural region could lead to that region becoming uninhabitable for its current population. Describe at least two distinct but related consequences that contribute to this outcome.

Connecting Climate Shifts to Human Displacement

Imagine you are an economic advisor analyzing a proposed city-wide ban on single-use plastic bags. Your task is to prepare a preliminary framework for this analysis. Your framework must clearly distinguish between the two main types of economic inquiry.

First, formulate three distinct, testable questions that would help describe the factual outcomes of the ban.

Second, identify two different value-based criteria that could be used to judge whether the outcomes are desirable, and briefly explain why different stakeholders in the city might prioritize these criteria differently.

Analyzing a Ban on Single-Use Plastics

Arrange the following events into a logical sequence that demonstrates how a sustained increase in atmospheric heat can lead to the loss of a critical food-growing region.

Match each projected climate pattern shift with its most direct threat to the habitability of a human-populated region.

The primary threat to the long-term habitability of a region from shifting climate patterns is the direct physiological stress of higher average temperatures on the human body, while impacts on food production and water resources are considered secondary consequences.

Based on the provided scenario, evaluate which of the described environmental changes poses the most significant long-term threat to the city's fundamental habitability for its large population. Justify your choice by explaining how this primary threat could create cascading problems that impact essential systems like housing, water supply, and public health.

Evaluating Habitability Threats in a Coastal Megacity

Based on the provided case study, evaluate which projection poses a more fundamental threat to the region's long-term habitability. Justify your conclusion by analyzing the nature of the environmental change and the feasibility of human adaptation in each scenario.
