water and carbon

what does 3-4 degrees of warming do to permafrost?

thaws up to 85% and makes carbon source, but uncertain how abruptly or when this could happen

what happens when you burn or drain peatland?

speeds up decomposition because youre drying it out so it makes a carbon source

what is hard and soft adaptation or mitigation?

hard = requires technological involvement

soft = involves legislation

what are some human factors that make climate change uncertain?

- disease outbreak like covid

- changing population size

- outbreak of war

- increase or decrease in the middle class

what are some physical factors that make climate change uncertain?

- feedback mechanisms like global warming from decreased albedo, tipping point if arctic melts

- rate of global warming and impact on peatlands, tipping point of atmospheric carbon and thermal expansion of ocean

- thermohaline circulation tipping point (transportation of nutrients in the worlds water. if it collapses then there would be reduced capacity for ocean to store carbon + drought in places.)
