REASONS for climate change

Human activity such as:

• Increased use of fossil fuels (oil, coal and gas)
• Increasingly intensive agriculture which emits greenhouse gases
• Carbon dioxide is the main cause of human-inducted climate change
• Deforestation

Natural causes:

• Volcanic activity
• Solar output
• Earth's orbit around the sun

CONSECUENCES of climate change

• Fresh water shortages
• Ice is melting which contributes to sea-level rise
• Number of floods will increase
• Storms and heatwaves
• Temperature changes are also affecting wildlife and other species as well

It's hard to say how greatly will the climate change in the future which makes it hard to evaluate the true consequences.
