Mitigating Climate Change
Reducing GHGs
reduction of energy consumption
use of alternatives to fossil fuels
replace high GHG emissions energy sources with low GHG emissions ones, eg hydroelectric and other renewables and nuclear power generation instead of burning fossil fuels
reduction of emissions of nitrogen oxides and methane from agriculture
improve efficiency of energy production
legislation
set national limits on GHG production and a carbon credit system
adopt carbon taxes to give firms disincentive
remove fossil fuel subsidy
personal carbon credits which can be traded encourage people to reduce their carbon footprint
even if mitigation strategies drastically reduce future emissions of GHGs, past emissions will continue to have an effect for some time
Geoengineering
Release sulphur dioxide from airplanes
Send mirrors into space between the earth and sun
Scatter iron, nitrates or phosphates on oceans to increase algal blooms
takes up carbon and acts as a carbon sink
Buil light colored roofs to increase albedo
Removing carbon dioxide from the atmosphere
using biomass as fuel source
using carbon capture and storage (CCS)
enhancing carbon dioxide absorption by the oceans through either fertilization of oceans with N/P/Fe to encourage the biological pump, or increasing upwellings to release nutrients to the surface
protecting and enhancing carbon sinks through land management
example: United Nations reduction of emissions from deforestation and forest degradation in developing countries (UN REDD) program
