Climate Change

Question 1

Climate Change

Answer 1

Describes a change in the average conditions (temperature and rainfall) in a region or over the planet over a long period of time

Question 2

Global Warming

Answer 2

A gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increase level of CO2, chlorofluorocarbons (CFCs) and other pollutants as a result of natural influence or hum actives

Question 3

Earth’s Atmosphere Gases

Answer 3

Nitrogen 78%, Oxygen 21%, Argon 0.9%, Other gases 0.1%

Question 4

Layers of Atmosphere

Answer 4

Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere

Question 5

Solar Variations

Answer 5

Refers to the amount of solar energy being released from the sun at any given point in time

Question 6

Milankovitch Theory

Answer 6

Changes in the earths orbit around the sun and changes in the tilt and wobble of the earths axis can lead to cooling or warming of the earths climate change because they change the amount of energy our planet receives from the sun

Question 7

Albedo

Answer 7

The reflectiveness of a surface. Lower the albedo the more radiations from the sun the gets absorbed by planet increasing temperature. Higher Albedo means the sun is more reflective , therefore more reductions is returned back to space, decreasing temperature

Question 8

Surfaces of High Albedo

Answer 8

Ice and Snow

Question 9

Surfaces of Low Albedo

Answer 9

open ocean and conifer forrest

Question 10

Where does CO2 come from

Answer 10

Life itself, Volcanoes, Ocean, Burning of fossil fuels

Question 11

Gases Contributing to Global Warming

Answer 11

Methane, CFCs, Ozone, Nitrous Oxide, Carbon Dioxide

Question 12

What is the Greenhouse Effect

Answer 12

A process when goes in earths atmosphere traps the suns heat, maintaining a comfortable place and temperature to live

Question 13

What is Enhanced Greenhouse Effect

Answer 13

Human actives such as burning fossil fuels, agriculture and land cleaning increase amount of greenhouse gases being released into atmosphere. Causing extra heat to be trapped making temperature rise

Question 14

Main Sources of Greenhouse Gases

Answer 14

electricity, transport, stationary energy, agriculture, industrial processes, waste, land use

Question 15

What is Kyoto Protocol

Answer 15

An agreement made in1997 and started in 2005 by the EU + 41 countries. Target was to reduced the 6 GHG emissions. Germany decreased by 8% while Australia increased by 8% due to high reliance on gases

Question 16

La Niña

Answer 16

-Warm water is pushed west against east coast of Australia
-Colder water on west cost of South America
-Stronger trade winds and walker circulation
-More evaporation and precipitation
-Increase chance of flood risk and trivial cyclones forming

Question 17

Netural Phase

Answer 17

-Trade winds blow for rest to west in tropical Pacific region
-Warm waters pushed west
-Less extreme weather
-Droughts + floods still possible

Question 18

El Niño

Answer 18

-Warm water pushed towards west coast of South America
-Walker circulation breaks down
-Colder ocean temps on east coast of Australia
-Less evaporation and precipitation
-Drought risk in northern and eastern Aus
-More heatwaves and fewer tropical cyclones

Question 19

Social Impacts on Climate Change

Answer 19

How we live, Where we live and what we can do, Air quality, Infectious diseases (dengue fever)

Question 20

Economic Impacts on Climate Change

Answer 20

Worldwide impact of CC is more than $1.2 trillion year and reduced global GDP by 1.6% in 2014. Sectors affected: Agriculture, energy, fishing, tourism and water

Question 21

Environmental Impacts on Climate Change

Answer 21

Heat, Fire, Drought, Se level rising, Coral reef bleaching, Biodiversity

Question 22

Countries Vulnerable to climate change

Answer 22

Coastal cities, Singapore, Japan, Pacific islands, Netherlands, Mountainous areas (LICs most vulnerable: Lack of funding and extreme whether
