Climate Change

Definition

Climate change refers to long-term alterations in temperature, precipitation, wind patterns, and other elements of the Earth's climate system. It is largely driven by human activities, particularly the burning of fossil fuels, deforestation, and industrial processes, leading to an increase in greenhouse gases in the atmosphere. The consequences of climate change have profound implications for ecosystems, social structures, and economic systems globally.

5 Must Know Facts For Your Next Test

1. Climate change leads to extreme weather events such as hurricanes, droughts, and floods, which can disrupt ecosystems and human communities.
2. The Paris Agreement is an international treaty aimed at limiting global warming to below 2 degrees Celsius compared to pre-industrial levels.
3. Melting ice caps and glaciers due to climate change contribute to rising sea levels, threatening coastal communities worldwide.
4. Biodiversity loss is exacerbated by climate change as many species struggle to adapt to rapidly changing environments.
5. Transitioning to renewable energy sources is considered one of the most effective strategies for mitigating the impacts of climate change.

Review Questions

• How do greenhouse gases contribute to climate change and what are their primary sources?
  • Greenhouse gases trap heat in the Earth's atmosphere, leading to a greenhouse effect that raises global temperatures. The primary sources of these gases include burning fossil fuels for energy, industrial activities, and agricultural practices such as livestock farming. This accumulation of greenhouse gases intensifies climate change and results in numerous environmental impacts.
• Discuss the role of international agreements like the Paris Agreement in addressing climate change challenges.
  • The Paris Agreement aims to unite countries in combating climate change by setting specific targets for reducing greenhouse gas emissions. By committing to limit global warming to well below 2 degrees Celsius, nations work collaboratively to implement policies that promote sustainability and renewable energy use. These international efforts are crucial for coordinating actions across borders and sharing best practices.
• Evaluate the long-term social and economic impacts of climate change on ecosystems and human societies.
  • The long-term impacts of climate change are profound for both ecosystems and human societies. Ecosystems face disruptions due to habitat loss and species extinction, leading to reduced biodiversity and altered ecological balance. For human societies, climate change can result in food and water shortages, increased health risks from heatwaves and diseases, and significant economic losses due to damage from extreme weather events. As a result, adapting to these changes is essential for ensuring resilience and sustainability in the future.
