water carbon and climate Flashcards
(24 cards)
what are the gasses that impact the climate
water vapour - warmer air holds more moisture , climate warms and air holds more moisture 70% of GHG.
carbon dioxide - warms the atmosphere
methane - more than doubled in the atmosphere since preindustrial
what is positive feedback
negative feedback
what is a water cycle positive feedback loop
temp rises
increase ice melting - more heat absorbed than reflected - albedo effect
ocean warms and more heat is absorbed and more ice melts
more ice melts resulting in further heating
temp rises
positive feedback loop for carbon cycle
temp rise
permafrost melts
organic matter is decomposed and carbon is released
increased carbon and methane in the atmosphere . enhanced greenhouse effect
what is mitigation
action of reducing the severity or seriousness of something
reduce emissions and increase the uptake of carbon from the atmosphere
adaptation
the process of adjusting to current or expected climate change
what are the main aims for the Paris agreement
limit average global temperature
every 5 countries raise goals and targets
what strategies are used to decarbonise the world
reduction in fossil fuel usage
renewable power technologies
what dies NET stand for
negative emissions technologies
what are nets designed to do
to take GHG out of the atmosphere to rebalance the carbon budget
examples of NET strategies
forestation
direct air capture
soil sequestration
what is SRM
soloar raditaion managent
reflecting fight back into space
reflects the suns energy back into space
counteracted the temp rise
examples of SRM
aerosol injection - spraying aerosols into the atmosphere would cool the planet
marine cloud brighting - use ships to spray saltwater into the atmosphere into the clouds above the sea .
ocean mirror-
challenges and and issues with reforesation
to store enough carbon an area of land the size of Australia would have to be planted
issues and challenges solar atmospheric injections
reduces the average temp but side effects
weakens monsoon rains in india
affect insect behaviour which would increase malaria
what are some adaptation strategies
hazard mapping - risk
warning sysetms
sea walls
flood and storm shelter
insurance
new building materials
pan A mitigation strategies
carbon capture and storage
tree planting
land use changing and deforestation
how can humans individually influence the carbon cycle
use cars less
make homes more energy efficient
How can people on a national or regional level influence the carbon cycle
reduce reliance on fossil fuels for heating and powering homes
afforestation and restoring degrading forests can increase carbon intake
governments can invest in carbon capture and storage
global ways the carbon cycle can be influenced
countries can work together to reduce the emissions
eg. Paris agreement
pros and cons of aerosol injection
- spraying aerosols into the atmosphere would cool the planet
pro - large amount of cooling
con - could decrease rainfall
pros and cons for marine cloud brighting
using spray ships to spray water - saltwater into the clouds
pro- clouds reflect more sunlight
con - could lead to unfavourable weather
pros and cons for ocean mirrors
ships putting millions of tiny micro bubbles which reflect sunlight
pro- overall help to cool
con- negative impact on marine life
