climate change 
how the average annual temperature changes overtime
global warming  
The warming of the Earth‘s atmosphere
Fossil fuels  
from the fossilised rains of plants and animals
Describe the greenhouse effect  
people emit different greenhouse gases into the atmosphere
the greenhouse gases create a layer around earth
that layer allows heat from the sun and other gases to come in
it does not allow any of the heat to go out
2 predictions regarding the the climate change problem
temperatures continue to rise
climate condition will not be the same in the future
3 examples of greenhouse gases
Carbon dioxide: from stations and factories that burn fossil fuels
deforestation: the cutting and burning of trees= carbon dioxide
4 effects climate change has on the world
= Sea temperature rises- water expands -sea level rises
= ice caps and glacier melt- sea level rises
= world‘s climate change-more rain, more heatwaves
4 effects climate changes has on us
= increase in in insects
= tropical diseases will be easily spread
= low-lying areas will be flooded- islands will disappear
= plants and without rain will suffer from food storage
2 positives effects of climate change in the UK 
=Plants will grow North
= Mediterranean summers
2 negative effects on climate change on the UK
=Insufficient snow
=risk of forest fires
The characteristics and importance of fossil fuels
-Fossil fuels .come from the fossilised of plants and animals
-provide our energy needs= electricity, heat
-plane power, car running out= non-renewable so cannot be replaced
-people continue to use them because they are cheap and easy to use.
Differences 15 years ago
-wind becoming main source of electricity
-nuclear: Safer But still in decline
—hydrogen: powers cars and vehicles
-coal major users like China are reduced its use
-Natural gas: slow price increase oil used but expensive.
-vehicles: more electric and hybrid cars
-homes: Super insulted to hold in heat, boilers used in the coldest days
Differences in 50 years
In 50 years
-Fossil fuels are over
-Solar giant solar panels are widely used
-nuclear: safer and cheaper but not used
-Hydrogen Clean and fully replaced oil
Wind: main source of electricity
-coal and oil: gone extinct found in muser
-natural gas pipelines now carry hydrogen
-Vehicles hydrogen -emission free
-home hydrogen replaces oil and gas
2 reasons why the UK has a reliable water supply.
-rain throughout the year
-money and technology to create reservoirs
2 predictions United Nation made about developing countries
-water is unevenly spread or hard to reach
-water shortage will cause problems between countries that rely on the same water supply
the characteristics of the WaterAid organisation 
-only UK charity dealing with the provision of clean water supply
-collects money through donations
-helped 10.2 million people
-tried to beat the threat of death caused by the lack of clean water
3 effects of water shortages in developing countries
-if wells dry up, women may have to walk 10-20km for its supply
-people, crops, animals will die
-polluted water= causes diseases like cholera
malnutrition 
health caused by a shortage of food or a poor diet
describe the United Nations findings on food supply.
-there is enough food to feed everyone
-people in developed countries produce more than enough than what they need, but people in developing countries cannot produce enough
-1.2 million people short of food in 2012
-predicted to rise to 4.2 million people by 2050
4 causes of food shortages in developing countries.
corruption = authority people les food for themselves instead of sharing with the people
-Large population =more people to feed than what they produce.
-Civil war = crops are ruined animals are killed Poor countries buy food from rich countries= expensive
-Climate change =less rainfall produces crops
-Drought -no rain for crops or animals to grow
-Insects eat crops
differences in food supply between poor and rich countries
Poor countries
-by 2050 half of the population will be underfed
-poverty will result in malnutrition -malnutrition=health problems caused by the shortage of food and poor diet
-food will be too little
Rich people
-people who eat too much of the wrong things are unhealthy
-people in developed countries are overweight
