Science W6 L5 - GLOBAL CLIMATE PHENOMENON Flashcards
Refers to any significant change in the
measure of climate lasting for an
extended period of time
Climate change
is the process
through which heat is trapped near
Earth’s surface by substance known as
“greenhouse gases”.
Greenhouse effect
Refers to the recent and ongoing rise in
global average temperature near Earth’s
surface.
Global warming
gas in the
atmosphere that absorbs and emits
radiation within the thermal infrared
range.
Greenhouse gas (GHG)
List some of the Main Indicators of Climate Change:
Air temperature over land
Sea surface temperature over land
Air temperature over oceans
Sea level
Ocean heat
Humidity
Tropospheric temperature
What are the 5 gases responsible for 99.5 % of the
greenhouse effect:
Water Vapor (H2O)
Carbon Dioxide (CO2)
Methane (CH4)
Nitrous oxide (N2O)
Chlorofluorocarbon (CFC)
List some of the Causes of Climate Change:
Human expansion of the greenhouse
effect.
Greenhouse effect- is the process
through which heat is trapped near
Earth’s surface by substance known as
“greenhouse gases”.
Greenhouse gas (GHG) – gas in the
atmosphere that absorbs and emits
radiation within the thermal infrared
range.
Burning fossil fuels
Releasing chemicals into the
atmosphere
Reducing the amount of forest cover
Rapid expansion of farming
Development and industrial
activities
MAN MADE ACTIVITIES THAT CONTRIBUTES
TO ATMOSPHERE’S GREENHOUSE GASES
FOREST FIRE
VULCANIC ERUPTION
PLANTS, ANIMALS AND HUMANS
OCEAN
NATURAL SOURCES CONTRIBUTES TO
ATMOSPHERE’S GREENHOUSE GASES
Rising temperature
Shrinking Ice Sheets
Sea Level Rise
Biodiversity depletion
Ocean Acidification
Extreme Weather
Effects of Climate Change
– any actions focused to reduce the
intensity of radiative forcing so as to lesson the effects of global
warming.
Climate Change Mitigation
Increasing carbon sequestration and conservation
Use of Bioenergy
Reduced Fertilizer use
Anaerobic digestion of waste
Improved energy efficiency
Ways to Mitigate the effects of climate Change
