PM- When it lands on ice and snow it darkens them slightly, leading to less sunlight being reflected back into space (reduced albedo), and contributing to global warming. Aerosols may be of either natural or anthropogenic origin and can influence climate in several ways

Interlinkages between Climate Change and Air Pollution
Introduction:
Climate change and air pollution are two global environmental issues that have significant impacts on human health and the environment. While they are two different issues, they are closely interlinked, and their negative impacts on the planet are often compounded.
Particulate matter and albedo:
Particulate matter is a type of air pollutant that is released into the atmosphere through human activities such as industrial processes, transportation, and burning of fossil fuels. It is also known to reduce albedo in Polar Regions. Albedo is the measure of the amount of solar radiation reflected back into space by the Earth's surface. When particulate matter reduces albedo, it contributes to an increase in global temperatures, which is a major cause of climate change.
Aerosols and climatic feedbacks:
Aerosols are tiny particles that are suspended in the Earth's atmosphere. They can act as both positive and negative climatic feedbacks. Positive feedbacks occur when aerosols absorb solar radiation and contribute to warming, which in turn leads to more aerosol formation, thus amplifying the warming effect. Negative feedbacks occur when aerosols scatter solar radiation and contribute to cooling, which in turn leads to less aerosol formation, thus reducing the cooling effect.
Conclusion:
In conclusion, climate change and air pollution are closely interlinked, and their impacts on the planet are often compounded. It is essential to address both issues simultaneously to mitigate their negative impacts on human health and the environment. Effective policies and strategies are needed to reduce greenhouse gas emissions and air pollutants, promote renewable energy sources, and encourage sustainable development practices.
