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
