Q

Potential impacts of climate change on outdoor environments

A

Increased intensity of droughts and floods
Reduction in fish stocks
Increase in evaporation rates, leading to greater humidity and extreme rain events
Exacerbation of melting of permafrost and glaciers (permafrosts contain high levels of methane which is far worse than CO2 which further increases climate change)

Q

urbanisation

A

the growth of cities and towns and the increasing number of people who live in urban areas.
impacts of urbanisation are:
increased demand for housing, water and land
increased waste disposal
erosion

21
Q

climate change

A

the long term alteration of global weather patterns due to a rage of factors such as human activities.

potential impacts of climate change on society
- decreased availability of water for nature and humans
- melting of ice in the arctic leading to rise of sea levels

22
Q

floods

A

they are a natural part of Australian ecosystem but have a huge impact of infastructure, human health and loss of life
An overflow of water onto normally dry land

23
Q

fire

A

burns through vegetation and wildlife causing widespread destruction and damage

24
Q

Environmental sustainability can be promoted in the following ways

A

Biomass (renewable energy, comes from organic matter like crops, wood, waste)
Solar power
Wind power

25
Q

Interdependence -

A

two or more things that are interconnected, relying on and influencing each other

26
Q

water quality

A

Crucial component of healthy and sustainable outdoor environment

Measuring water quality
Testing the quality can indicate the health of the water

Taste, odour and appearance - (turbidity)
These factors can also give an indication on the health of the water

27
Q

Ecosystem diversity

A
  • variety of habitats, natural communities and ecological processes in the biosphere
28
Q

Land degradation

A

Refers to detrimental changes in the conditions of the land due to human interactions
Changes linked to a reduction in the productive capacity of a land and its economic value

29
Q

Impacts of urbanisation include:

A

Increased demand for land for housing
Leading to loss of vegetation, habitat and biodiversity
Increased demand for water
Reducing availability for the native flora and fauna
Air, water and soil pollution due to runoff from urban areas and chemicals from agriculture

30
Q

Potential impacts of climate change on society

A

Decreased availability of water for nature and humans
Restriction of irrigated cropping due to limited water
Melting ice of arctic and antarctic, leading to rising sea levels and floods

31
Q

Potential impacts of climate change on outdoor environments

A

Increased intensity of droughts and floods
Reduction in fish stocks
Increase in evaporation rates, leading to greater humidity and extreme rain events

32
Q

Potential impacts of flood on society

A

Damage to infrastructure, buildings, roads, key transport hubs
Impacts of regional and national economies

33
Q

Potential impacts of flood on outdoor environments

A

Crucial for maintaining ecological functions and promoting biodiversity
Establish connections between rivers and their surroundings

34
Q

Potential impacts of fire on society

A

Impacts include loss of life, property and infrastructure
After initial burn there are still impacts to soil and water quality

35
Q

Potential impacts of fire on outdoor environments

A

Impacts on plants, animals and ecosystems
After initial burn there are still impacts
Through burned soil going into streams and rivers which can cause too much nutrients to flow in and cause overgrowth of algae

36
Q

Climate feedback loop -

A

a cycle that accelerates or decelerates a warming trend, such as bushfires creating conditions that encourage more intense bushfires

37
Q

Aesthetic value

A

Based on outdoor environments visual appearance and the emotional responses they evoke

38
Q

Biodiversity

A

the variety of all living things and their interactions

39
Q

Education

A

Learning while physically in the environment allows for examples to be experienced, enabling effective consolidation of the curriculum

40
Q

Climate change

A

any long-term shifts in average weather patterns, including alterations in temperature, precipitation and wind patterns

41
Q

Action to combat climate change on a local level

A

In victoria the government is taking actions to be net zero by 2050 and helping to ensure that communities and businesses are prepared to deal with the effects of climate change

In 2023 Victoria had the following targets
2025: 28-33% below 2005 levels
2030: 50% below 2005 levels

42
Q

Action to combat climate change on a national level

A

Under international climate agreements, at the time of printing, Australia has two targets to reduce greenhouse gas emissions
5% below 2000 levels by 2020
26-28% below 2005 levels by 2030 (under the paris agreement)

After a government change in 2022, Australia raised its expected emission cuts from 30% by 2030 to 40% by 2030

43
Q

Action to combat climate change on an international level

A

Latest report from the Intergovernmental Panel on climate change (IPCC),
- levels of CO2 emissions, surpassing levels seen in the past two million years. These emissions have contributed to global warming approximately 1.1°C from 1850 and 2000
Without immediate action to reduce greenhouse gas emissions the goal to limit global warming from reaching 1.5°C to 2°C will become unattainable

44
Q

What are United Nations climate change conferences?

A

They are prominent international gatherings over the past two decades
- multilateral conferences
- international discussion on climate change and bring together representatives from governments worldwide.

45
Q

kyoto protocol

A

International agreement that commits industrialised countries to limit and reduce their greenhouse gas emissions with specific individually agreed targets

key for climate change mitigation

with 147 signatories as of 2020 the protocol is a key component of the United Nations framework convention on climate change

46
Q

Paris agreement

A

Globally binding treaty on climate adopted by 196 signatories at the 21st Conference of the Parties

Agreement aims to limit the global average temperature rise to well below 2°C and pursue efforts to limit it to 1.5°C

47
Q

3 pillars of sustainability

A

social, economic and environemental sustainability.
used to describe the connect of sustainability
these pillars do not work in isolation but rather are connected

48
Q

promoting environemnetal sustainability

A

solar power, wind power and biomass

49
Q

interdependence

A

of two or more things that are interconnected
