Cold Deserts
- Found north of the Arctic Circle and south of the Antarctic Circle.
- Characterized by low precipitation and cold temperatures.
Siberian Tiger Adaptations
- Thick fur: Provides insulation against cold.
- Belly blubber: Additional insulation and protection.
- Paler stripes: Camouflage in snowy environments.
- Excellent vision: Crucial for hunting in both day and night.
Arctic Woolly Bear Mammoths (Caterpillars)
- Extremely active in summer for food storage.
- Resistance to freezing allows them to endure winter.
- Freeze over the winter.
Cushion Plants
- Grow close to the ground for wind protection.
- Collect dust for nutrients.
Arctic Poppies
- Have hairy stems for heat retention.
- Orientate with the sun to maximize energy absorption.
Climate of Polar Regions
- Less concentrated solar heat due to Earth's curvature.
- Dry air.
- High-pressure zone, causing sinking air and minimal precipitation.
Permafrost Melting in Siberia
- Caused by rising temperatures due to climate change.
- Has both positive and negative effects.
Positive Effects
- Unearthing fossils.
Negative Effects
- Release of methane and harmful substances.
Permafrost Management Strategies
Rewilding
- Introduce large mammals.
- Reduce plant cover to increase heat reflection.
- This method is proven in small areas but needs a large number of animals to be effective.
Painting Roads White
- Reflects heat and prevents permafrost melt.
- This method is utilized in other permafrost areas but requires considerable financial investment.
