Describe the pattern of climate change from the Quaternary to the present day.
During the Quaternary, global temperature has shifted between cold glacial periods that last for around 100,000 years, and warmer interglacial years that last around 10,00 years.Since the last glacial period 15,000 years the temperature has increased

Reliability of ice and sediment cores
Scientist drill for long pieces of ice they then see what gases are trapped in the ice, they can also collected organisms trapped in the ice, Antarctica's ice cores are 400,000 years old making them very reliable.
2 of 13
Reliability of tree rings
As a tree grows it forms a new ring each year. the rings are thicker in wetter and warmer condition, Some trees can be 10,000 year old they are reliable but hard to get because It means chopping the tree down.

Reliability of diaries and paintings
Historical diaries are able to tell us the condition of weather over hundreds of years ago. Paintings can also show the climate. these date back 500 years. They are not very reliable because they just give one person's viewpoint.

Causes of natural climate change.
orbital change, vacations of how the earth moves around the sun being closer to the sun. Volcanic activity, Solar outputs, Asteroid collisions.
5 of 13
The green house affect.
Short incoming waves of radiation (heat from the sun) enter the atmosphere, Natural greenhouse gases keep some radiation in however most the the radiation is reflected back in to space. Allowing a balanced amount of each.
6 of 13
The Enhanced green house affect.
Pumping more chemicals in to the air, a build up of gases making it harder for the sun's rays to bounce back in to space.
7 of 13
Social impacts of climate change.
Increased threat of wildfires affect people's homes, Low lying costal areas flood, not enough water to much evaporation, Lower crop yield increase starvation.
8 of 13
Economical impacts of Climate change
Permafrost melting causes buildings to move, Crops suffer from climate change affecting the profits of farmer, water shortages have to pay for water treatment, more extreme weather.
9 of 13
Environmental impacts of Climate change
Temperature rise, Glaciers shrink, Sea ice shrinks aswell, Coral reefs suffer from bleaching
10 of 13
Social impacts of climate change in the UK
Deaths from cold related illnesses, heat exhaustion, drier summers, population density increases int he south, flooding increases in low lying areas.
11 of 13
Economical impacts of Climate change in the UK
Boost tourism, Skiing decline in Scotland, longer growing seasons, droughts affect the South, Fishing could be affected due to storms, Fish population.
12 of 13
Environmental impacts of climate change in the UK
Temperature will increase, winter rainfall will increase, Droughts, Floods, Sea level rise. Loss of habitats.
