Water and Carbon overlap Flashcards
Water is around what % of vegetation biomass
50%
What is the most important intersection between water and carbon
water can store dissolved carbon and transport it
E.g. rainwater
What is the pH of unpolluted rainwater
5.6 due to acids in the troposphere
how acidic can polluted rainwater become
4 or lower
What is the arctic ice feedback loop
POSITIVE ice has high albedo but is melting due to increased temps which reveals the dark ocean which has a low albedo
what is the carbon cycle feedback loop (NEGATIVE)
higher temps cause longer growing seasons for plants so more carbon is sequestered
what is the carbon cycle feedback loop (POSITIVE)
increasing temps melts permafrost releasing greenhouse gases which increase the enhanced greenhouse effect and cause global warming
what chemical to Phytoplankton release
DMS (Di-methylsulfide)
what does DMS do?
promotes cloud formation
why does DMS cause global cooling
more clouds means more sun reflected (high albedo) so less insolation
What do current CCS solutions account for
0.001% of all emissions
what is climate change mitigation
reducing emissions
what is climate change adaption
making SEEP changes in response to climate change
How can we modify photosynthesis
increase globally forested areas to increase sequestration
How can we modify land use to mitigate climate change
carbon farming
what is carbon farming
one type of crop is replaced with another that can absorb more CO2
how much of Sri Lanka’s forests were destroyed in the last 100 years
3/4
how many mangrove seedlings were planted in Sri Lanka in 2017
700k
which nonprofit helped Sri Lanka rebuild its forests?
Seacology
How can we modify deforestation
FSC certified wood
Carbon offsetting
Selective logging
why is FSC certified wood better
ensures only wood grown sustainably can be sold under this label
what is carbon offsetting
an entity can compensate for their greenhouse emissions by investing in projects elsewhere
what is selective logging
only certain trees are felled based on set criteria such as species or age which protects younger trees and leaves the ecosystem intact
What % of virgin forest was set out to be protected in Brazil
80%
