Answer:
Natural factors and human activity
Explanation:
As humans, we are the number one source of global warming and climate change. Human activity has fueled this change since the 1800s when humans burned fossil fuels, which released heat-trapping gases into the blanket of the earth that trapped the sun's heat. Other modern-day causes like generating power, manufacturing goods, cutting down forests, using transportation, producing food, and using too much energy, etc., lead to global warming and climate change following that.
