Question

First of all, Please type the answer of this question from thank you

how a balance between incoming solar radiation and outgoing longwave radiation must be maintained in order to keep annual temperatures the same. Climate scientists are mostly worried about this imbalance, especially the decrease of outgoing longwave radiation that would lead to a warming of the atmosphere. At the Pierce College Weather Station (www.piercecollegeweather.com (Links to an external site.)Links to an external site.), we can track these types of radiation and get a sense for the radiation budget and resulting temperature at Pierce College.

I want you to share your observations of how your local community might be impacting a global imbalance. Comment on changes in landscape (urbanization), automobile use, or industry pollution that may add to the delay or reduction of outgoing longwave radiation escaping to space. This part must be at least 2 paragraphs,

Answer 1

We known that Earths energy machine is driven by sunlight which acts as fuel for this machine and to strike a balance between outgoing long wave radiation and short wave radiation there are many factors which are involved in this process.Sun emits this energy in the form of short wave radiation because of the huge energy it has and short wave radiation are higher in energy.Hence, they reach the earth surface mostly as visible and UV rays.After reaching the earths surface what happens with these rays is that they get absorbed by the clouds and other constituents of Earth.

Now, this energy needs to be emitted back in to space in order to balance out the energy budget of earth and that is why this energy is emitted back as long wave radiation which have less energy and also earth has less energy unlike the sun.Loss of this energy is essential as Earth looses most of its energy through this and results in cooling.But when this OLR decreases it should be a cause of concern for us.

This imbalance is caused by a wide range of different human induced activities which has a cumulative effect on the temperature of earth.These activities gives rise to a huge gain in the CO₂ concentration which is why this word has gain so much popularity and a cause of widespread concern for us.At community level we contribute to this heating by increasing usage of personal automobiles rather than going for public transport , advancement in technology has greatly changed our lifestyles making it more simpler and easier but this demands more energy consumption.Landscape changes are one of the most important because its taking place at a faster rate.Most of the land being cleared off to built new houses which means clearing off the existing vegetation which leads to temperature rise.Setting up of Industry depending on its type can reduce the amount of OLR escaping the surface by introducing more amount of GHGs in to the atmosphere.

Its these small communities which add up to become the entire human population causing a massive damage and hence at community level if people realize and take necessary steps things will start to change.
