Climate engineering

14 important questions on Climate engineering

What is climate engerering?

Artificially changing the climate , improving it, cooling down the planet. Mitigate.

large scale intentional modifcation of natural systems to counter climate change.

What diffrent types of climate energering are there?

- solar radiation management SRM
- Carbon Dioxide Removal CDR / negative emission rtechnologies NET ( not clear where mitigation measures and cdr are.

Direct air capture (CDR)

They suck up Co2 from the sky. They wash co2 deom rhe. Carbon monoculs liquidfied.

What are the cons of DAC?

- you need a lot of water
- much energy needed
- You need to store the carbon somewhere, and cant go in the atmospgere.
- You need a location for this.
- Huge scale needed
- Oil companies are biggest investors in DAC.

Enchances olvine weathering

Co2 in coastal areas are taken by olivine, found in rocks, you can enchange this if you add rocks. Very small scale ..

CDRbio energy with carbon capture and stoarge

You burn trees, co2 is captured and stored. Trees take up co2large scale were you replace trees on large scale. Private market intitiative. BEES

Risk and issues concerning climare engineerging at three stages
?

- Discussion/ lab work
* risk compensation/ moral hazard
- Field research
* slippery slip to development.
* risks to environment and human health
- Deployment
* decioson making SRM, how deciding
* disagreement among states
* termination
* ethics.

The role of policy & law risk- risk trade off

Shows the legal difficulty, we have climate change as a potential catastrophe.

- potential ultrs-hazardous risks of climate engineering...

Principles of int. Environmental law

- no harm principle, we have climate change which is harmfull, we take climate engineerings measures which can also harm. 
- cooperate in mitigating transboundary environmental risks
- Polluter pays principle
- Precautionary principle
- Principle of integenrational equity

Paris agreement climate enigineering

It is not in the pa, not mentioned, you can find provision that are relevent. Art.4 second main goal.
- development and diffusion of technology, you could agrue, the requirement to save climate also involves climate enigineering.fff

London dumping convention and protocol

Very big convention on pollution of the ocean, it is global and binding. It prohibits the dumping of waste and chemicals in the ocean. Art.6bis, annexes that can be dont at all 4. Annex 5 is with a permit.there needs to be monotroing. National governments are competnt authorities.

Convention on Biological Diversity CBD

Very big convention. Global. They adopted resolution prohibiting climate change if harmfull biodiversity,

Outer space treartty

Only relevant for the mirror,  no object in space unless under authority of state party & liability.

Convention on Long Range Transbounderty air pollution

Relevant stratospheric aersole injection.

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
