Q

What is the Colombian Exchange?

A

After the discovery of the Americas, ‘Old World’ and ‘New World’ crops (eg. Maize) were exchanged between Europe and America’s. This:
Permanently changed global pollen records
Brought over diseases that practically wiped out indigenous Americans and turned abandoned farms into big forests (CO2 sinks) resulting in global drop in CO2 and global cooling for 200 yrs

Q

What is the atomic weapons testing theory?

A

Post WW2: many countries develop nuclear weapons, resulting in increased radioactive material rising to atmosphere, spreading all over world and settling back down again, accumulating in sediment, bone and tissue. Partial ban in nuclear weapons testing in early 1960s resulting in ‘golden spike’ in 1964. Criticism: not a big change to Earth tho

Q

What were the pre-industrial Co2 levels? (1800)

A

275-280 ppm

49
Q

Co2 levels in 1958 when they had began to be measured by scientists?

A

310-320

50
Q

What is the greenhouse effect?

A
  • earth’s surface heats up + emits infrared radiation
  • some radiation escapes into space = cools earth a bit
  • some infrared radiation is absorbed + trapped in atmosphere so Earth doesn’t cool too much
  • visible light passes through the atmosphere from sun
51
Q

What is the enhanced greenhouse effect?

A
  • earth emits radiation as it has heated up
  • more radiation emitted from earth is trapped in the atmosphere because of excessive greenhouse gasses in the atmosphere
  • more energy enters the atmosphere than leaves it = earth heats
  • light passes into atmosphere
  • less outgoing radiation from Earth escapes into space = earth heats
  • human burning of fossil fuels increases concentration of gasses in atmosphere
52
Q

What are 5 pieces of evidence to show climate change has occurred?

A

Drought, positive feedback loops, ice, extreme heat and oceans

53
Q

How does drought show that climate change has occurred?

A
  • Dry places are getting drier + wet places are getting wetter
  • rainfall has become both rarer and more extreme when it happens
54
Q

How does extreme heat show that climate change has occured?

A
  • Heat waves are becoming more common in more temperate countries such as the UK
  • annual global temperature records being surpassed every year
55
Q

How do positive feedback loops show evidence of climate change?

A

OVERALL INCREASES GLOBAL TEMPERATURES
- permafrost: increase in temperature will melt permafrost + all organic matter that’s been preserved inside will decompose and gigatons of Co2 will be released into the atmosphere
- albedo effect: white colour ice reflects radiation, but because of temp change, the ice melts and shows black rock underneath which absorbs heat and melts more ice

56
Q

How do the oceans show that climate change has occurred?

A
  • liquids expand when heated so sea levels rise + ice sheets melt, adding to this
  • heating of water bleaches coral reefs
  • many islands are predicted to go underwater
57
Q

How does ice show that climate change has occurred?

A
  • burning fossil fuels = greenhouse gasses that prevent heat from leaving atmosphere
  • melts polar ice caps (albedo effect)
  • more heat melts permafrost + lots of CO2 will be released into atmosphere
58
Q

Define positive feedback loop

A

When an event occurs repeatedly, and in doing so, causes itself to occur in more intensity each time.

59
Q

Examples of positive feedback loops

A

Albedo effect, permafrost melting

60
Q

Carbon footprint

A

The best estimate we can get of the full climate change impact of something

61
Q

CO2e

A

Total climate change impact of all the greenhouse gasses caused by an item expressed in the amount of CO2 it would take to have that impact in 100yrs

62
Q

How to reduce carbon footprint in travel

A
  • electric cars are good at reducing local air pollution
  • fly frugally + offset CO2
  • walk and cycle more often
  • use public transportation
63
Q

How to reduce carbon footprint in food

A
  • enjoy more plant-based food as they require much less processing
  • buy local produce to reduce food miles
64
Q

How governments can mitigate climate change

A
  • invest in renewable energy sources (solar, wind, tidal, hydro)
  • reduce the sale of petrol + diesel cars
  • promote more plant-based diets
  • install more heat pumps are compared to boilers as these burn fossil fuels
65
Q

74
Q

Adaptations of epiphytes

A
  • perch on high branches to reach the sun
  • feed on rain + nutrients from rotting leaves
75
Q

Adaptations of butress roots

A
  • tallest trees in emergent layer have them to prevent them from falling over
76
Q

What do drip tips do for a leaf?

A

Leaves have long ends to allow the rain to drip off

77
Q

What do sharp edges do for a leaf?

A

Sharp to keep hungry predators away

78
Q

What do wax coats do to a leaf?

A

Thick waxy coat keeps rain + insects off

79
Q

Major threats to rainforest

A
  • deforestation
  • logging
  • palm oil plantations
  • bushmeat trade = lack of biodiversity = breaks food chains
  • cattle grazing + soya bean farms
80
Q

Impacts of deforestation

A
  • loss of a major carbon sink, making it harder for CO2 to be removed from atmosphere
  • more species are threatened to extinction from loss of habitat
  • rainforest plants are a medicinal source, we risk losing life-saving drugs before they have been found
81
Q

How to reduce deforestation

A
  • National parks/conservation areas
  • REDD agenda
  • Ecotourism
82
Q

How do national parks reduce deforestation?

A
  • create safe havens for wild species
  • deforestation is illegal or heavily restricted in these areas
83
Q

How does ecotourism reduce deforestation?

A
  • rainforest countries should realise how much profit can be made by leaving forests alone to get tourists
  • tourists come in small groups to visit rainforest to learn abt it
84
Q

How does the REDD agenda reduce deforestation

A
  • pays rainforest countries to leave their forest alone
  • countries will realise that conservation is more profitable than deforestation so deforestation rates will reduce
85
Q

Why GIS is better than paper maps?

A
  • GIS is easily backed up, paper is easily damaged
  • GIS is easily changed bc of layers, paper can’t be changed
  • GIS has compact storage, paper takes up a lot of space
