Answer:Variations in the sun's energy - sunspot activity raises global temperature.
Volcanic eruptions , large quantities of volcanic dust in the atmosphere shields the Earth from incoming heat, (exposure to the Sun's rays), lowering global temperature.
Explanation:Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.
