Module 5 Flashcards
Long-term average weather pattern in one place.
Climate
Influenced by slow changes in the ocean, the land, the orbit of the Earth about the sun, and the energy output of the sun
Climate
Fundamentally controlled by the balance of energy of the Earth and its atmosphere
Climate
Conditions at one particular time and place, including temperature and rainfall.
Weather
Can change very rapidly from day to day, and from year to year.
Weather
Changes involve shifts in temperatures, precipitation, winds, and clouds.
Weather
_ is defined as the average weather condition of the atmosphere over a long time in a particular place. Throughout the history of humankind, _ played an important role in where people have chosen a place they want to settle.
Climate
_ refers to the day to day atmospheric condition of a particular place and time. can be pleasant or destructive. _ can destroy houses, properties, vehicles, and agricultural activities and even result in death.
Weather
Intense weather
“A change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere which is in addition to natural climate variability observed over a comparable period of time.”
Climate Change according to United Nations Framework Convention on Climate Change (UNFCCC)
“Any change in climate over time, whether due to natural variability or as a result of human activity.”
Climate Change according to Intergovernmental Panel on Climate
Change (IPCC)
_ is created by complex interactions between the Sun, our atmosphere, oceans, land, ice and biosphere which in turn are affected by an area’s latitude, elevation, terrain, and distance from coasts, mountains and lakes
Climate System
When we talk about the climate system, the _ is known to be the main driver.
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.

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.
Note that if the air is _, high pressure is expected with beautiful and glorious weather, while _ air has low pressure with precipitation.

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.
For instance, the strongest current in the world is located at the _.
Gulf Stream
Thus, an _ has the potential to create an imbalance of the climate system and affect our climate.

increase rapidly.
GHGs
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
Basically, there are three main human sources of ghgs:
• energy generation and industrial processes
• transportation and
• land-use and agriculture
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).
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.
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.
