Study Notes
Weather vs. Climate
- Weather describes short-term changes (e.g., temperature, precipitation, sunshine).
- Climate describes long-term average weather patterns (at least 30 years).
Heat Sinks
- Heat sinks absorb thermal energy without significant temperature increase.
- Water is an example.
Glaciers and Ice Caps
- Glaciers are slowly moving masses of ice formed by accumulated snow.
- Ice caps are large ice coverings on land.
Watersheds
- Watersheds are land areas where water collects and drains.
- Open watersheds drain into oceans.
- Closed watersheds only drain through evaporation or groundwater.
Water Desalination
- Water desalination removes salt from water to make it drinkable.
- Desalination plants are large and necessary due to water scarcity in many regions.
- Methods include the thermal process (evaporation and condensation) and reverse osmosis (high-pressure filtration).
Water Conservation
- Conserving water is crucial for addressing scarcity issues, environmental protection, and creating a sustainably future.
- Overuse depletes freshwater resources, harming the environment.
- Reduces costs, protects water quality, and ensures equitable access.
Polar Bears
- Polar bears rely on multi-year ice for hunting (ringed and bearded seals).
- They have a reduced feeding period during summer, waiting for the ice to return.
Global Warming Factors
- Human activities contribute to global warming.
- Burning fossil fuels, deforestation, and livestock farming increase greenhouse gases.
- These gases enhance the greenhouse effect, leading to higher temperatures.
Melting Polar Ice Effects
- Melting glaciers and ice caps have significant uncertainty, but if entirely melted, global sea levels would rise 230 ft, flooding coastal areas.
