Climate Change Flashcards
what is the defenition of adaptation?
actions taken to adjust to natural events such as climate change to reduce potential damage
Climate change
A long-term change in the earths climate
Mitigation
Action taken to reduce or eliminate the long-term risk to human life from natural hazards
orbital changes
Changes in the pathway of the Earth around the Sun
quaternary period
The period of geological time from about 2.6 million years ago to the present characterised by the appearance and development of humans
recent evidence for climate change
- shrinking glaciers and melting ice
-rising sea levels
-seasonal changes
What is the greenhouse effect?
Buildup of man-made gases preventing sunlight from escaping earths atmosphere causing it to heat up
Solar activity
Sunspots are dark patches that appear on the surface of the Sun. the more sunspots the greater the Sun is energy
Volcanic activity
Big volcanic eruptions that can change the earths climate
Alternative energy sources
7 types of renewable energy these include solar, wind, titde, geothermal, HET, biomass and nuclear
Carbon capture
Storing carbon dioxide underground so It can’t get into the atmosphere
What does Re-planting trees do?
Reduces CO2 levels increases oxygen production
Rising sea level coping mechanisms
Flood barriers can be built and in areas that can’t afford the fences like Bangladesh people build there houses on top of embankments, managing water supply
How can we manage water supply?
Water metres can be installed to prevent water wastage, rainwater can be collected and waste water can be recycled
