Sustainability
Environmental considerations
Energy Conservation
Reduce wasteful consumption. Limit growth in demand and contribute towards energy security but a short term, small impact, solution.
Renewable Energy
Solar, wind, hydro/water.
Hydrogen - but highly flammable and not viable
Fusion - not viable yet
Location dependent.
Non-Renewable Energy
Fossil Fuels, finite amount left, renewable over a geological timescale.
230 coal
100 oil
170 gas
Weather
Conditions of the atmosphere in the short term due to changes in temp, pressure and precipitation.
Climate
Average weather pattern over a long period.
Climate Change
Long term change in climate.
Enhanced Greenhouse Effect
More GHG mean more radiation reflected/trapped mean warmer.
Impacts of Increased GHG levles
Climate Change Debate
Impacts of Climate Change
Uncertainty in Global Climate Models
Mitigation
Reduction and/or stabilisation of GHG emissions and their removal from the atmosphere.
Adaptation
The adjustment in natural or human system in response to actual or expected climate stimuli or their effects, moderating harm or exploiting benefits.
Mitigation Strategies - Geo-engineering
Mitigation Strategies - Stabilise/Reduce GHG
Reduce energy consumption - increase efficiency of tech. change lifestyle. Carbon Taxes.
Reduce GHG from agriculture - change cows diet to seaweed, less methane. Sustainably agriculture.
Replace FF with renewable energy
Mitigation Strategies - Remove CO2 From the Atmosphere
Adaptation Strategies
International Action
