GLACIERS CS Flashcards
What is the Case study for SHORT TERM CLIMATE CHANGE?
Little Ice Age & Loch Lomond Stadial
SHORT TERM CLIMATE CHANGE: When was the Little Ice Age and why did it occur?
19th Century during Holocene epoch - followed by medieval warm. Due to natural factors - axial tilt/wobble
SHORT TERM CLIMATE CHANGE: What were temperatures in the Little Ice Age and what did it cause?
low levels of -2 degrees and led to crop failures, starvation, can’t sell crops
SHORT TERM CLIMATE CHANGE: When did temperatures plunge in the Loch Lomond Stadial?
12,500 years ago temps plunged in glacial conditions in the Pleistocene epoch. Last Uk glacier
SHORT TERM CLIMATE CHANGE: Why did the Loch Lomond Stadial occur?
continental drift as cold water disrupted ocean currents
SHORT TERM CLIMATE CHANGE: BY how much were temps lower than normal in the Loch Lomond Stadial?
6-7 degrees lower tan average
What is my Case study for a GLACIATED LANDSCAPE?
Greenland
GLACIATED LANDSCAPE: What % of ice covers the island?
80% ice cover - world largest island
GLACIATED LANDSCAPE: When was it granted a self government and what is its population?
1979 and 56,000 people with 88% inuit
GLACIATED LANDSCAPE: What is the environmental value of Greenland?
support fragile biodiversity of endemic plants / mammals (artic fox, whale, polar bear and reindeer) used for scientific research
GLACIATED LANDSCAPE (environmental value): How much global ice does Greenland hold?
10% of ice as it has a role in the water cycle
GLACIATED LANDSCAPE: How much does Greenland’s ice melt contribute to sea level rise?
0.3mm per year and if all melted sea would rise 7m flooding NY and London
GLACIATED LANDSCAPE: What is the cultural value of Greenland?
Use landscape for traditional lifestyle - hunting/fishing.
GLACIATED LANDSCAPE (cultural value): What is the threats to Greenland cultural value?
climate change/loss of sea ice reduces hunting size and space/ drill ice cores
GLACIATED LANDSCAPE: What is the economic value of Greenland?
meltwater provides hydroelectric/ tourism (cruises) and if ice retreats exposes oil, gas and minerals
GLACIATED LANDSCAPE: What are threats to Greenland?
Climate Change/polar bears/political disputes
GLACIATED LANDSCAPE: How does climate change threaten Greenland?
as sea retreats, shipping routes open in Northwest Passage connecting pacific/Atlantic = marine pollution
GLACIATED LANDSCAPE: How does polar bears uncertain future threaten Greenland?
Hunting ground reduced, pop (persistent organic pollutants) have been found in bears which reduces reproduction
GLACIATED LANDSCAPE: How does political disputes threaten Greenland?
2007, Russia claimed part of the artic seabed, causing conflict with Artic nations such as Denmark and Canada
What is my case study for a PERIGLACIAL LANDSCAPE?
Yamel Peninsula - Russia
What is the Case Study for RELICT LANDSCAPES?
Lake District
RELICT LANDSCAPES: What are threats to the Lake District?
Footpath erosion, farming on upland areas, water storage/forestry
RELICT LANDSCAPES (footpath erosion): How many visitors does the LD get?
16 million visitors a year over 2000 miles of footpaths.
RELICT LANDSCAPES (footpath erosion): How does these visitors effect the landscape?
walkers destroy vegetation, compact soil, reduces infiltration rates, exposes soil that is washed away, gullies form, widen paths, less nutrient rich particles
RELICT LANDSCAPES (footpath erosion): What has been done to reduce this threat?
LD national park authority (LDNPA) repair over 40 years, rangers use techniques but is slow and expensive
RELICT LANDSCAPES (farming on upland areas): Where is used for sheep grazing?
fell tops over 600m
RELICT LANDSCAPES (farming on upland areas): How does grazing threaten the landscape?
degrade land, erosion, threaten landscape due to roaming freely.
RELICT LANDSCAPES (farming on upland areas): How does farming threaten landscape?
on valley floors produces lots of energy
RELICT LANDSCAPES (Water storage/forestry): How does water threaten the landscape?
Thirlmere dam flooded small Hamlet/pub/restaurant, more water needed from aqueduct to support more people
What is the case study for a GLACIERS?
Sagarmatha NP
GLACIERS: What are the threats to the Np?
Tourism, Natural causes/disasters, Climate/everest
GLACIERS (tourism): How many people visit the area in 2014?
over 37,000, which increases demand for energy and erosion/water pollution
GLACIERS (tourism): Due to increased temps, in 2013 how much did glaciers shrink by?
13% in 50 years, influences sherpa people
GLACIERS (natural causes/disasters): In 2004 what hit the NP?
28 mag earthquake, as tectonically active, which degrades the environment
GLACIERS (Climate/Everest): How many people have now reached Everest’s summit?
over 6000 and 90% guided, causing pollution, rubbish, crowded, and travel causes gg
GLACIERS (Climate/Everest): By how many m is the snowline higher than it was 50 years ago?
180m higher, causes floods/glacial outbursts
What are my case studies for HUMAN CAUSES?
polar tourism, Yosemite np, antartic treaty
HUMAN CAUSES (polar tourism): How many tourists does the Antarctic receive a year?
40,000 tourists as it reps a “journey of a lifetime”. Doubled over 2 mill in 2014, compared to 1990’s
HUMAN CAUSES (polar tourism): How many cruise ships reach Svalbard in2015?
5o ships for activities like snowmobiling, sledging, northern lights, 200 landing sites
HUMAN CAUSES (Yosemite NP): How many visitors does the NP get?
5 mill with 90% concentrated in 6% of area
HUMAN CAUSES (Yosemite NP): What does this tourism cause?
degregation of veg, invasion of speices, wildfires, pollution, overcrowding (selfie taking)
HUMAN CAUSES (Antarctic treaty): When was the treaty signed?
in 1961 with 53 signatory nations
