Answer 1

• Human activity -- Produces greenhouse gases.
• Greenhouse gases -- Cause atmosphere to trap more heat.
• Sun's output -- Can vary.
• Ice age -- Peaked 20,000 years ago.

Step-by-step explanation:

• The human activity has created a large amount of greenhouse gases by the burning of fossil fuel and this fossil fuel is non-recyclable and causes the atmosphere to trap more heat and rise in global climate average. The ice ages have peaked in the past 10 - 20,000 years ago during the periods of interglaciation.
