Study Notes
Ocean Currents and Climate
- Ocean currents help transfer heat to the atmosphere, generating global winds.
- Changes in wind patterns can cause changes in ocean currents, which in turn affect climate.
- Upwelling occurs when warm waters move out to sea, and cold, deep waters rise to the surface, bringing valuable nutrients with them.
El Niño
- El Niño is a warm water current that flows from west to east across the Pacific Ocean near the equator and down the western coast of South America.
- It occurs when the winds that cause upwelling fail to blow, resulting in a "heat wave" in the ocean.
- El Niño strikes every 2-7 years, bringing dramatic changes in world climates.
- It can cause droughts, heavy rains, and severe flooding in different regions.
Climate Change
- The greenhouse effect is the natural process by which the Earth's atmosphere traps heat energy from the sun, warming the environment.
- However, an overload of greenhouse gases, such as carbon dioxide, disrupts the climate, leading to disastrous consequences.
- If the amount of greenhouse gases continues to increase, the Earth will significantly become warmer, affecting living things and ecosystems.
Effects of Global Warming
- Heat waves, wildfires, floods, and droughts are occurring worldwide due to global warming.
- Rising water levels will submerge coastal regions and melt polar glaciers.
- Climate change poses serious public health threats, including air pollution, extreme heat, infectious diseases, drought, flooding, and extreme weather.
