Please use Global warming as topic design a real teaching case based on problem-based learning.

Title: "The Impact of Global Warming on Arctic Ecosystems"

Grade Level: High School or College

Learning Objectives:

1. Understand the causes and consequences of global warming on the Arctic ecosystem.
2. Analyze the impact of anthropogenic activities on climate change.
3. Develop solutions to mitigate the effects of global warming on Arctic ecosystems.

Scenario:

You are a team of environmental scientists working for a research organization that specializes in studying the impact of climate change on Arctic ecosystems. Your team has been tasked with developing a comprehensive report on the impact of global warming on Arctic ecosystems and potential solutions to mitigate its effects. The report will be presented to the Arctic Council, an intergovernmental forum that addresses issues faced by the Arctic governments and the indigenous people of the Arctic.

Problem:

The Arctic ecosystem is one of the most vulnerable ecosystems to global warming. The Arctic region is warming at a rate twice as fast as the rest of the world, leading to melting sea ice, permafrost thaw, and changes in the Arctic Ocean's chemistry. The melting of sea ice is causing the displacement of marine mammals, including polar bears, and the loss of habitat for indigenous communities that depend on the Arctic's natural resources. The thawing of permafrost is releasing greenhouse gases, including carbon dioxide and methane, into the atmosphere, further exacerbating global warming.

Task:

Your team will develop a report that outlines the impact of global warming on Arctic ecosystems, including the causes and consequences of the warming temperatures. The report should also analyze the impact of anthropogenic activities on climate change, such as the burning of fossil fuels and deforestation. Your team should consider potential solutions to mitigate the effects of global warming on Arctic ecosystems, such as reducing greenhouse gas emissions, investing in renewable energy, and protecting Arctic habitats.

Process:

1. Research the impact of global warming on Arctic ecosystems and the causes and consequences of climate change.
2. Analyze the impact of anthropogenic activities on climate change, including the burning of fossil fuels and deforestation.
3. Develop potential solutions to mitigate the effects of global warming on Arctic ecosystems, such as reducing greenhouse gas emissions, investing in renewable energy, and protecting Arctic habitats.
4. Present the report to the Arctic Council, highlighting the key findings and recommendations.

Assessment:

The report will be assessed based on the following criteria:

1. The accuracy and completeness of the research on the impact of global warming on Arctic ecosystems and the causes and consequences of climate change.
2. The analysis of the impact of anthropogenic activities on climate change.
3. The development of potential solutions to mitigate the effects of global warming on Arctic ecosystems.
4. The presentation of the report to the Arctic Council, including the clarity and effectiveness of the presentation.

Conclusion:

This problem-based learning scenario will enable students to understand the impact of global warming on Arctic ecosystems and develop potential solutions to mitigate its effects. By working in teams, students will develop critical thinking and problem-solving skills, as well as collaboration and communication skills. This scenario will also enhance students' knowledge of climate change and its impact on the environment, which will enable them to become responsible global citizens.
