Are There Any Human Activities That Accelerate This Process?

Yes, several human activities contribute to the acceleration of ice cap melting:

Fossil Fuel Consumption: The burning of fossil fuels for energy releases large amounts of CO2 and other greenhouse gases into the atmosphere.
Deforestation: Cutting down forests reduces the number of trees that can absorb CO2, exacerbating the greenhouse effect.
Industrial Processes: Many industrial activities release pollutants that contribute to global warming.
Agriculture: Farming activities, particularly livestock farming, release significant amounts of methane, a potent greenhouse gas.
