 The Recent Role of the Greenhouse Effect

3. Main TopicsMain Topics
 The Main Greenhouse Gases
 Humans are largely responsible for recent
climate change
 Climate change affects life

4. Earth’s temperature is a
balancing act

5.  Earth’s temperature depends on the balance
between energy entering and leaving the
planet’s system .
 When incoming energy from the sun is
absorbed by the Earth system, Earth warms.
 When the sun’s energy is reflected back into
space, Earth avoids warming.
 When energy is released back into space,
Earth cools.

6. Incoming radiation
1.94 gm-cal/min
on earth surface
(Radius 6.96 x 10
5
km)
150,000,000 km
6000 K
sun

8. Factors caused Earth’s climate change
 The amount of heat retained by Earth’s
atmosphere
 Variations in the sun’s energy reaching
Earth
 Changes in the reflectivity of Earth’s
atmosphere and surface

10. Greenhouse effect
Greenhouse gases (GHGs) like water vapor
(H2O), carbon dioxide (CO2), and methane
(CH4) absorb energy
Slowing or preventing the loss of heat to
space. In this way, GHGs act like a blanket,
making Earth warmer than it would otherwise
be.

11. Our Earth is warming
 Earth's average temperature has risen by
1.4°F over the past century, and is
projected to rise another 2 to 11.5°F over
the next hundred years.
 Small changes in the average
temperature of the planet can translate
to large and potentially dangerous shifts
in climate and weather.

13. The Recent Role of the
Greenhouse Effect

14.  Since the Industrial Revolution began
around 1750, human activities have
contributed substantially to climate
change by adding CO2 and other heat-
trapping gases to the atmosphere.
 These greenhouse gas emissions have
increased the greenhouse effect and
caused Earth’s surface temperature to rise.
 The primary human activity affecting the
amount and rate of climate change is
greenhouse gas emissions from the burning
of fossil fuels.

15. The Main Greenhouse
Gases

16.  CO2
 CH4
 nitrous oxide (N2O)
 several others

17. Greenhouse Gases
(GHG) :
(1) PFCs
(2) HFCs
(3) SF6
(4) CH4
(5) CO2
(6) N2O

20. Humans are largely
responsible for recent
climate change

21.  Over the past century, human activities
have released large amounts of carbon
dioxide and other greenhouse gases into
the atmosphere.
 The majority of greenhouse gases come
from burning fossil fuels to produce
energy, although deforestation, industrial
processes, and some agricultural
practices also emit gases into the
atmosphere.

22. Climate change affects Life
Regional impacts of
global change forecast by
the IPCC

23. Decreasing snowpack in the western
mountains
5-20 percent increase in yields of rain-fed
agriculture in some regions
Increased frequency, intensity and
duration of heat waves in cities that
currently experience them.
North America

24.  Gradual replacement of tropical forest by
savannah in eastern Amazonia
 Risk of significant biodiversity loss through
species extinction in many tropical areas
 Significant changes in water availability for
human consumption, agriculture and
energy generation.
Latin America

25. Europe
 Increased risk of inland flash floods
 More frequent coastal flooding
 Increased erosion from storms and sea
level rise
 Glacial retreat in mountainous areas
 Rreduced snow cover and winter tourism
 Extensive species losses
 Reductions of crop productivity in
southern Europe.

26. Africa
 By 2020, between 75 and 250 million
people are projected to be exposed to
increased water stress
 Yields from rain-fed agriculture could be
reduced by up to 50 percent in some
regions by 2020
 Agricultural production, including access
to food, may be severely compromised.

27.  Freshwater availability projected to
decrease in Central, South, East and
Southeast Asia by the 2050s
 Coastal areas will be at risk due to
increased flooding
 Death rate from disease associated with
floods and droughts expected to rise in
some regions.
Asia

31. Global Climate Change: Recent Impacts
Phenomena Likelihood that trend occurred in late 20th century
Cold days, cold nights and frost less frequent over land
areas
Very likely
More frequent hot days and nights Very likely
Heat waves more frequent over most land areas Likely
Increased incidence of extreme high sea level * Likely
Global area affected by drought has increased (since
1970s)
Likely in some regions
Increase in intense tropical cyclone activity in North
Atlantic (since 1970)
Likely in some regions

32. Global Climate Change: Future Trends
Phenomena Likelihood of trend
Contraction of snow cover areas, increased thaw in
permafrost regions, decrease in sea ice extent
Virtually certain
Increased frequency of hot extremes, heat waves
and heavy precipitation
Very likely to occur
Increase in tropical cyclone intensity Likely to occur
Precipitation increases in high latitudes Very likely to occur
Precipitation decreases in subtropical land regions Very likely to occur
Decreased water resources in many semi-arid areas,
including western U.S. and Mediterranean basin
High confidence

33. El Niño
El Niño meaning The Little
Boy, or Christ Child in Spanish
originally recognized by
fishermen off the coast of
South America in 1600s.
Appearance of unusually
warm water in the Pacific
Ocean.
Basing on the time of
year,around December during
which these warm waters

34. The El Niño refers to the
large-scale ocean-
atmosphere climate
interaction linked to a
periodic warming in sea
surface temperatures
across the central and
east-central Equatorial

36. La Niña
La Niña means The Little Girl in Spanish. La
Niña is also sometimes called El Viejo, anti-
El Niño, or simply "a cold event."
La Niña episodes represent periods of
below-average sea surface temperatures
across the east-central Equatorial Pacific.
Global climate La Niña impacts tend to be
opposite those of El Niño impacts and in the
tropics, ocean temperature variations in La
Niña also tend to be opposite those of El
Niño.
