Understanding Climate Change
This video explains what climate change is, why it matters, and how human activities contribute to it. It also discusses the impact of climate change on oceans, sea levels, and extreme weather events.
What is Climate Change?
- Climate change refers to an abrupt increase in the Earth's temperature.
- The Earth's temperature has increased by 1.2 to 1.4 degrees Fahrenheit in just the last century.
- Human activities are likely responsible for this increase in temperature due to increased consumption of natural resources and release of greenhouse gases.
Impact on Oceans
- Climate change has caused the global temperature of oceans to increase by more than 0.3 degrees Fahrenheit since 1969.
- Ocean acidification is a direct effect of increased dissolved CO2 due to climate change which puts calcifying species at risk and threatens the entire ocean food web.
Rising Sea Levels
- Sea levels have risen by 6.7 inches in just the last century due to melting glaciers and ice sheets.
- The rate of sea level rise has nearly doubled in the last decade alone.
Extreme Weather Events
- Natural disasters like floods, tornadoes, and deadly heat waves are becoming more frequent due to climate change.
Personal Actions
- Individuals can help combat climate change by recycling, reusing items, using public transportation or walking instead of driving cars, turning off electronics when not in use, eating less meat and more locally grown vegetables and foods.
Conclusion
Climate change is a real and serious issue caused by human activities. It has devastating consequences for our planet, including ocean acidification, rising sea levels, and extreme weather events. However, individuals can take personal actions to help combat climate change and be part of the solution.
