1.7 - Glocal Carbon Cahnge

Question 1

Pre-Industrial Revolution

Answer 1

A mixture of fast carbon cycle, and slow carbon cycle. Fairly fast fluxes of carbon removed CO2, balancing the carbon cycle.

Question 2

Fast Carbon Cycle

Answer 2

Biological Cycle

Question 3

Slow Carbon Cycle

Answer 3

Geological Cycle

Question 4

Anthropogenic CC

Answer 4

Carbon has been transferred from fossil stores into the atmosphere, therefore slow exchange is now very fast.

Question 5

IPCC Evidence

Answer 5

Natural - Milankovitch, sunspot cycles, El Niño, Ocean oscillation BUT there’s more changes in temperatures CO2 than actual CO2. Human activity has moved carbon around the cycle but only half has been removed by the fast cycle.

Question 6

What Sort Of Carbon Changes Have Happened.

Answer 6

310 ppm to 4000ppm showing a 40% increase since 1700s.
Main additions and fossil fuels and deforestation
Most carbon should stay in the atmosphere for 2000 years.

Question 7

What Does Carbon Change Implicate

Answer 7

Climate System
Eco-Systems
Hydrological Systems
Anthropogenic Pertubation

Question 8

Climate Systems

Answer 8

CO2 causes 20% of water vapour, and provides heating to water vapour. AS CO2 increases, temperature increases and more water evaporates, therefore increasing the effects of greenhouse heating.

Question 9

Marine Eco-Systems

Answer 9

Warmer oceans decrease phytoplankton which limits sequestration. More CO2 fertilises phytoplankton and marine temp extends growing season and increase humidity.

Question 10

Terrestrial Eco-Systems

Answer 10

Water stressed plants are more vulnerable to fires which release trapped carbon.

Question 11

Hydrological Systems

Answer 11

Warmer temperatures evaporates more water increasing humidity, which then cools and rains. Increased temp slows the growth of new cells increasing the size of stomata meaning more water is lost and more CO2 is taken in.
