chap 14 Flashcards
denotes significant statistical changes in climate that
continue for a long period
Climate change
IPCC
Intergovernmental Panel on Climate
Change
valuates climate change science and released reports on global
climate change.
IPCC
is a phenomenon caused by gases naturally
present in the atmosphere that affects the behavior of the heat energy radiated by
the sun
natural greenhouse effect
An increase in greenhouse gases in the atmosphere
Enhanced Greenhouse Effect
The latter is a process that disrupts the equilibrium of the
Earth’s climate due to the increased concentration of greenhouse gases that
increases the global average surface temperatures
Enhanced Greenhouse Effect
Earth’s atmosphere is composed of __% Nitrogen, ___% Oxygen, and
__% natural greenhouse gases such as carbon dioxide, methane, nitrous oxides,
and halocarbons.
78% Nitrogen, 21% Oxygen, and
1% natural greenhouse gases
are gases in the atmosphere that trap and absorb heat
or infrared radiation emitted from the earth’s surface and reradiating it back to the
earth’s surface,
Greenhouse gases
The most important anthropogenic greenhouse gas; contributes the greatest portion of warming caused by human activities.
Carbon Dioxide
A natural gas that comes from natural sources such as wetlands and termite
mounds
methane
Naturally occurring as part of the global water cycle.
water vapor
Naturally occurring in the stratosphere but largely found in the troposphere
because of human activities.
ozone
Emissions come from agricultural and industrial activities and the combustion
of solid wastes and fossil fuels.
nitrous oxide
Emissions come from commercial, industrial, or household uses.
sythetic gasses
Contributes the largest amount of greenhouse gas emissions.
Electricity production
Uses fossil fuels to produce goods from raw materials in the
factories. Fossil fuels emit greenhouse gases.
industry
Common sources of greenhouse gases in homes are burning fossil
fuels and handling wastes.
commercial and residential
Greenhouse gases are released from the livestock.
agriculture
CO2 is absorbed by trees, the primary absorber of carbon dioxide.
Cutting and burning trees highly emit greenhouse gases.
land use and forestry
the unusually
rapid increase in earth’s average surface temperature over the past century
primarily due to the greenhouse gases released by people burning fossil fuels.”
global warming
Climate change occurs as a result of _____________
global warming.
What is the present scenario of the earth’s global surface temperature
human-induced warming reached approximately 1
degree Celsius (1.8 degrees Fahrenheit) above pre-industrial levels in 2017.
_____________________ in the atmosphere is used as an indicator that
will significantly provide information about global warming.
Carbon dioxide concentration
is considered as one of the most important inputs for economic
growth
energy
too much use of the natural resources.
Overconsumption
a steady increase in population increases the demands
for fuels and products produced from natural resources.
overpopulation
the use of old and outdated power-generating
equipment by the energy-producing firms which are less efficient and
cannot meet the world’s demands of energy.
poor infrastructure
the fossil fuel-dependent economy
of many countries mainly relying on non-renewable resources like coal as
the main sources of energy.
unexplored renewable energy options
commissioning of new power plants
can help address the global problems on the world’s energy supply and
demand.
delay in commissioning power plants
the less concern of the people on energy conservation
resulted to more energy being wasted.
Wastage of energy
pipeline burst, volcanic eruptions,
floods, and earth quakes are some events that cause a shift in the world’s
energy supply and demand. Specifically, it causes inflation of oil prices.
Major accidents and natural calamities
can cause a global shortage of energy supply especially
if it happens in a major oil-producing countries like the Middle East countries
war and attacks
such as strikes by trade unions in an oil-producing
firms, military coups, tax hikes, political events, severe hot summers or cold
winters can suddenly increase the demand of energy and affects the supply.
