A
Climate System
12
Q
When we talk about the climate system, the _ is known to be the main driver.
A
sun’s energy
As the sun emits energy and penetrates the atmosphere, it is absorbed, or the clouds are reflecting some. As the energy enters the earth, it brings in heat as well. A natural process such as water evaporation, air currents rising, and radiation in the earth’s surface removes or loses heat. Some of the heat that enters the atmosphere goes out through the atmosphere back to space, but some heat is absorbed by greenhouse gases like carbon dioxide, water vapor, and methane. In this way, the atmosphere will be able to re-emit back the heat. Eventually, all heat will always go back at the space, but not before it raised the Earth’s surface enough to support living organisms on earth.

Q

A
climate system
Since the earth is not flat and tilted, the planet’s exposure to the sun changes at different latitudes and seasons. Generally, there is more heat in the middle portion of the earth (equator) than the Polar Regions. About inequality, the movement or circulation of heat moves from the equator to the poles through the atmosphere and oceans. As observed in tropical countries, arising from thunder, clouds are apparent. These warm forces the air to rise and drift to the poles at high levels. Air that is more cooling flows in the direction opposite the surface of the earth, which will set up cells. The same cells are developing in other areas as it goes up towards the Polar Regions. Furthermore, the boundaries between cells contain two different air, which is either rising or sinking towards the earth.
23

24
Q
The _ and _ is responsible for developing currents in the ocean.
A
changing temperature of the sea and salinity or saltiness of the seawater.
In the north Atlantic, the surface water there is cooled by the winds of the arctic. Those water characterized by being cold, dense and salty, sinks and moves toward deep within the central portion of the ocean. In exchange, the water is moved by the Gulf Stream towards the northeastward, specifically at the shallow portion, to replace it. This movement carries warmth to the northwestern of Europe, creating a milder climate distinct to other places with similar latitudes. It is because of these interactions of the sun’s energy and the ability of the atmosphere and oceans to travel heat across the globe – creates various climates in different parts of the planet and eventually alters daily weather.
25
For instance, the strongest current in the world is located at the _.
Gulf Stream

increase rapidly.
GHGs
50
Human activities that lead to the increase in concentration of greenhouse gases include:
• worldwide deforestation
• increasing industrial activity
• motor vehicle emission and;
• waste management practices
• Carbon sequestration
51
Basically, there are three main human sources of ghgs:
• energy generation and industrial processes
• transportation and
• land-use and agriculture
52
There are other three man-made ghgs which were initially intended to replace chlorofluorocarbons (CFCs) to
prevent further depletion of the ozone layer. However, they were found to be harmful greenhouse gases.
These are:
Hydrofluorocarbons (HFCs)
Perfluorocarbons (PFCs)
Sulfur hexafluoride (SF6).
53
GHGs are even termed “_” since most of them have additional effects, mostly human health.
“climate active pollutants”
Let us have a review on the greenhouse effect. Note that the greenhouse effect is a natural phenomenon. Remember that greenhouse gases function to envelop the earth to serve its purpose of keeping or let us say trapping the sun’s heat and energy instead of letting it go back outside the atmosphere. In this way, the earth can maintain enough warm temperatures to support living organisms on earth. There are also various greenhouse gases in terms of their capability to absorb and keep the heat (global warming potential) as well as the different half-life in the atmosphere.
54
The _ is the sole responsible for driving the climate change – the amount of solar energy that the earth receives and the amount of solar energy that goes back outside the atmosphere.
alteration of the balance of the earth’s energy
Technically, the earth receives more energy as humans lessen the amount of heat going outside the atmosphere. Ever since industrialization has begun for over two centuries, anthropogenic activities have contributed to elevating the number of greenhouse gases into the atmosphere.

• Take the bus, ride a bike or walk; maximize the use of public transport systems.
• Recycle cans, bottles, plastic bags and newspapers. When you recycle, you help save natural resources.
• Generate as little trash as possible, because trash in landfill sites emit large quantities of methane, and if burned, carbon dioxide is released.
• Reduce on the use of non-renewable sources of energy and increase in the use of renewable energy sources such as solar, hydro, and wind energy.
• Encourage cooperation and partnerships among other institutions in programs and activities that would help fight global warming.
• Strengthen environmental awareness and action among your colleagues by initiating innovative and creative information and education campaigns.
• Consume less, share more, live simply.
