Climate Change Flashcards
What are anthropogenic causes for climate change:
-Greenhouse effect due to greenhouse gasses like methane and carbon dioxide
These are due to human activities such as deforestation, peat harvesting, soil degradation and ocean warming which all started with the Industrial Revolution
What is the positive feedback of loss of reflective snow and ice in terms of global warming?
Albedo is the extent to which a surface reflects light. Higher albedo means more reflected light. Light coloured surfaces such as snow and ice have a high albedo and vice versa .
As polar ice caps melt, more of sun’s energy is absorbed which increases global warming
Higher temperatures accelerates ___________ which increases _______ ________ released
Decomposition
Carbon dioxide
List some impacts of climate change
Carbon changes in forests
Polar habitat change
Changes in ocean currents
Range shifts of temperate species
Threats to coral reefs
What is the definition of carbon sequestration
The process of capturing and storing carbon dioxide from the atmosphere
How do we increase natural carbon sequestration?
Forest regeneration and afforestation
Peat bog restoration
