What is the definition of climate?
a long term change in the earths climate
the state of the atmosphere at a particular place
the average weather conditions at a place over many years
What is the definition of climate change?
a long term change in the earth's climate
a short term change in the earth's climate
The Quaternary Period to the present day is the period of geological time from about 5 million years ago to the present
What evidence is there that the earth's temperature is increasing?
Records show a 7oF increase in temperature
Glaciers melting
Oceans warming
Ice sheets growing
Sea levels rising
Increase in extreme weather events
Why does the use of lots of cars cause an increase in global warming?
They are dangerous
They release greenhouse gases such as carbon dioxide
They use petrol
What are some other human causes of climate change?
Deforestation
Storms
People
Spark Plug
Sun's output
Nitrious oxide occurs naturally in lightning in storms and so causes global warming
Carbon dioxide occurs naturally in volcanoes
One impact of climate change is sea levels rising - since 1945 1960 1860( 1945, 1960, 1860 ), sea levels have risen by 1m 0.4m 0.6m( 1m, 0.4m, 0.6m ) due to ice sheets and glaciers melting. Low lying countries are experiencing severe flooding tsunamis earthquakes( flooding, tsunamis, earthquakes ) and rising sea levels increase coastal erosion tsunamis global warming( coastal erosion, tsunamis, global warming ).
An impact of climate change is glaciers and ice sheets melting - some predictions say polar bears may disappear from the Arctic by 2050 2020 2100( 2050, 2020, 2100 ). A glacier in Columbia Greenland The Arctic( Columbia, Greenland, The Arctic ) retracted 7.5km 2km 15km( 7.5km, 2km, 15km ) in 25 years and in 2009 an ice shelf the size of Kent Jamaica The Maldives( Kent, Jamaica, The Maldives ) snapped.
An impact of climate change is human health - An increase in temperature increases ❌, and skin cancer. Diseases may also spread ❌ and there is increased growth of ❌ due to droughts.
An impact of climate change is natural disasters - hurricanes tsunamis earthquakes( hurricanes, tsunamis, earthquakes ) are happening five times three times twice( five times, three times, twice ) as often as they used to 100 50 200( 100, 50, 200 ) years ago due to rising sea temperatures. The annual number of North Atlantic tropical storms has risen from 9 12 5( 9, 12, 5 ) (1990) to 20 15 17( 20, 15, 17 ) (1998).
An impact of climate change is precipitation - higher temperatures mean less snow and more rain. Changes in rainfall patterns could mean that Africa's Asia's Europe's( Africa's, Asia's, Europe's ) lakes and rivers could run dry by 2050 2100 2030( 2050, 2100, 2030 ). Countries could also be severely affected by droughts volcanoes tsunamis( droughts, volcanoes, tsunamis ).
What is the definition of Mitigation?
Action taken to eliminate climate change or natural disasters completely
Action taken to change the way we live so it fits with climate change
Action taken to reduce or eliminate the long-term risk to human life and property
2 advantages of wind power:

It is the cheapest form of energy
2 disadvantages of wind power:
It is expensive
It can be noisy
It can cause air pollution
Wind turbines can be unattractive
2 advantages of Solar Power:
No pollution
It generates power all the time
It does not need much land
It is cheap
2 disadvantages of Solar Energy:
It doesn't work at night
It causes noise pollution
2 advantages of Hydroelectric Power:
70% of the world is covered in water
It is cost effective
It does not need much land space
2 disadvantages of Hydroelectric Power:
It only works when the water is moving
It can damage the habitats of plants and animals
There is lots of pollution
What is carbon capture?
Removing waste carbon dioxide and depositing it where it will not enter the atmosphere
Removing carbon dioxide from the atmosphere and storing it underground
Capturing carbon from rocks and humans
Young trees can absorb more carbon dioxide more quickly as they are still growing
How much government funding was given to plant 4 million trees in England in 2014?
£1 million
£4 million
£6 million
What are carbon credits?
You pay to be allowed to emit a certain amount of carbon dioxide
You gain credits depending on how much carbon dioxide you have emitted
You are fined if you emit over a certain amount of carbon dioxide
1 advantage and 1 disadvantage of carbon credits:
The money is used for projects to help the environment
Larger companies can use it as an excuse to pollute freely
It means that there is no carbon dioxide emitted
It is not effective

157
193
175
What was the Copenhagen Deal?
Recognises the need to limit global temperature from rising no more than 2oC
International Emissions trading agreement
Developed countries would fund conservation programmes in developing countries
The Greenhouse gases are: - Water - M - O - Carbon - Dioxide
What is irrigation efficiency?
Making sure your water use is efficient
Effectively irrigating things
Making sure your food use is efficent
What are two advantages of biotechnology?
Improves the quality of the crops
Helps reduce carbon emissions
The plants are bigger
Give one advantage and one disadvantage of the Thames Barrier:
If it wasn't there water would be as high as the lampposts in some places
It was only built to last until 2030
It was only built to last until 2020
It causes lots of pollution
Give two advantages of the Essex Marshes:
It would take a once in a 1000 years storm to get past them
No storm will ever be able to get past them
It provides habitat and saltwater marshes for rare birds and animals
