What is impact of burning wood on climate?

The Outcome of aerosols actions?

What are the real causes of aerosols?

The Impact of Burning wood and Grassland on the Climate:

1.    Wood burning in the fireplaces may seem like giving pleasure and charming way to warm the rounds and houses, but there are considerable negative effects of burning these substances, which release smokes and small particles, known as aerosols into the atmosphere and then polluting the climate;
2.    This is among the human activities which spoil the environment;
3.    Depending on their properties and in what part of the atmosphere they are found;
4.    The dusts, droplets and other matters floating in the atmosphere known as aerosols can reflect sunlight back into the space and cool the globe.

The Outcome of aerosols actions:

1.    Aerosols or the small droplets in the atmosphere reflect directly the sunlight into space, thus reducing the amount of energy reaching the earth's surface;
2.    They act as condensation nuclei that form clouds;
3.    Large concentration of droplets makes these clouds more reflective and prevents rainfall that prolongs cloud lifetimes;
4.    The more clouds and the increasing cloud life appear to have a greater impact on global climate;
5.    Aerosols can absorb sunlight and cause increasing local heating and affect the way heat is radiated back into space by the Earth.

The Causes of aerosols:

1.    Generating the small particles and droplets in the atmosphere implicates many factors;
2.    There are natural factors, such as the eruption of volcanoes, the wind dusts, the water vapor, and the gas bubbles, whereas the human activities carry implications on industrial emissions and on the burning of forests and grasslands;
3.    Even though many details of aerosols actions are known, but the influence and the relative contribution of man-made aerosols, as compared to naturally occurring aerosols is not well known yet;
4.    Cloud droplets over land are smaller than that over water;
5.    Marine cloud droplets over Northern Hemisphere are smaller than that over Southern Hemisphere;
6.    There are also significant variations in droplet sizes during times such as dry seasons, when forests and croplands burn;
7.    Knowing such like variations in droplet sizes is important in understanding the potential effects on climate, because the smaller droplets with larger number concentrations seem to make the clouds more reflective to sunlight.
