Climate change 
A large-scale, long-term shift in the planet's weather patterns or average temperatures
Earth has had tropical climates and ice ages many times in its 4.5 billion years
Natural causes of climate change
Orbital changes
Sun Spots
Volcanic eruptions
Orbital changes
Changes in the orbit of the sun increases or decreases temperatures
Sun Spots
Dark spots on the sun increase the amount of energy the Earth receives
Volcanic eruptions 
Releases huge amounts of dust and gases that can block sunlight
Ways to manage climate change
Carbon capture
Planting trees
International agreements
Renewable energy
Carbon capture
New technology designed to reduce climate change by taking Carbon Dioxide from the atmosphere and storing it in the ground
Planting trees
Increases the amount of carbon absorbed from atmosphere
International agreements 
Countries aim to cut emissions by signing international deals and by setting targets e.g. Paris 2015
Renewable energy 
Replacing fossil fuels based energy with clean/natural sources of energy
Quaternary period
The last 2.6 million years
Recent evidence for climate change 
Global temperature changes
Melting ice sheets and glaciers
Sea levels rising
Seasonal changes with birds migrating
Enhanced greenhouse effect
Recently there has been an increase in humans burning fossil fuels for energy. These fuels (gas, coal and oil) emit greenhouse gases (carbon dioxide). This is making the Earth's layer of greenhouse gases thicker, therefore trapping more solar radiation and causing less to be reflected. As a result, the Earth is becoming warmer.
Ways to adapt to climate change
Agricultural adaptions
Reducing the risk of rising sea levels
Agricultural adaptions 
Climate change will have huge impacts on agricultural systems, farmers will have to adapt by changing crops, livestock and techniques and manage water supplies
Reducing the risk of rising sea levels 
We need to manage our costal areas as sea levels rise
