Future of Global
Warming:
- CO2 emissions are still rising. If we continue to use as much then the temperature will hit 5.
- Need to hit the negative global emissions
- Australia is less developed in rural places. Africa will be less developed in urban places
- Climate change may become a runway problem. The tipping point could see positive feedback cycles leading to an uncontrollable GHG release.
- Thermohaline circulation will decrease as less phytoplankton cannot reach the deep ocean
Management Options:
|
|
Adaptation:
Humans change to improve resilience and reduce vulnerability
|
Mitigation:
Actions to reduce GHG emissions
|
Water Conservation &
Management:
Collecting rainwater to adapt to more droughts and evaporation
|
Carbon Taxation:
Tax on carbon emissions.
|
SMART Irrigation:
Apps measure when irrigation is needed. Adapt scarcity of water
from drought
|
Renewable Energy
Switching:
Using more renewable or radical energies
|
Land Use Planning:
Don’t build on floodplains. Adapt to more frequent rainfall
|
Energy Efficiency:
Energy rating on appliances
|
Solar Radiation:
Mirrors in space: Adapt to increased CO2 emissions
|
Afforestation:
China planting more trees
|
Carbon Capture
Storage:
Storing carbon in the ocean.
|
|
ALL OF THESE REDUCE GHG
EMISSIONS
|
|
Agreements:
- Paris Agreement
- Kyoto Protocol
- None of these work because they are non-binding, some countries do follow them but those who don’t use more.
- They need to be binding e.g fines if not followed.
