Mitigating Climate Change
Remove CO2
Carbon capture and storage
Transporting CO2 absorbing rocks to areas with high emissions
Expensive and not sustainable- only a short term solution
CO2 injection storage
short term and expensive
Use more biomass
Burining Biomass instead of fossil fuels- planting and growing offsets the carbon released from bruning
Soot is not good for health
Increase amounts of photosynthesis
Prevent Deforestation- Releases carbon and reduces carbon sinks
UN- Reducing Emissions form Deforestation and forest Degradation
new technologies like vertical farming and green skyscrapers
Geoengineering
build light colored roofs to increase more reflection and albedo
Easiest possibility
increase global dimming by releaseing sulphur dioxide from airplanes
risky
scatter iron nitrates and phosphates on oceans to increase algal blooms, which take up more carbon and act as a carbon sink
risky
deflect solar radiation by sending mirrors in between the sun and Eath
Expensive
Aerial Reforestation
Quick way to rebuild rainforests
More rainforests= increase carbon sink
Reducing GHGs
reduction of emissions of nitrogen oxides and methane from agriculture
reduce methane production, eg methane from cows can be reduced by changing their diets
capture more methane produced from landfill sites
sustainable agriculture
reduction of energy consuption
more efficient: improving fuel economy in motor car engines, hybrid or electric vehicles
insulate and cool buildings more efficiently
energy efficient light bulbs and appliances
reduce overall demand for energy
adopt carbon taxes and remove fossil fuel subsidy
use of alternatives to fossil fuels
replace high GHG emission energy sources with low GHG emission ones, eg hydroelectric and other renewables and nuclear power generation instead of burning fossil fuels
