Study Notes
Greenhouse Effect
- The greenhouse effect allows sunlight to enter the atmosphere while trapping heat, contributing to global warming.
Rising Ocean Temperatures
- Increased ocean temperatures can strengthen hurricanes, leading to more severe weather events.
Air Quality and Illness
- Poor air quality can lead to increased health issues, which may result in a decline in population.
El Niño Phenomenon
- El Niño is characterized by warm water shifting towards the South American coast, impacting global weather patterns.
Carbon Dioxide and Global Warming
- Rising levels of carbon dioxide in the atmosphere correlate with global warming.
- Carbon dioxide has a long lifespan in the atmosphere, contributing significantly to climate change.
- Other greenhouse gases enhance the warming effect initiated by carbon dioxide.
Lifespan of Greenhouse Gases
- Carbon dioxide stays in the atmosphere for a period ranging from weeks to thousands of years, influencing the climate significantly.
Wind Patterns
- Global wind patterns, known as prevailing winds, play a crucial role in climate distribution across different regions.
Effects of Wind Patterns
- Changing wind patterns during El Niño relocate warm water eastwards, altering climate dynamics.
Impact of Wind Patterns on Climate
- Wind patterns affect precipitation levels in various areas, directly influencing regional climates.
Factors Contributing to Global Warming
- Both natural factors and human activities are significant contributors to the phenomenon of global warming.
La Niña Conditions
- La Niña typically results in cooler winters and stronger prevailing winds, which affect weather patterns.
Definition of Global Warming
- Global warming refers to the long-term rise in the Earth's average temperatures, primarily due to human-induced factors.
