WGU D199 SUMMARY AND TEST(INTRODUCTION TO PHYSICAL AND HUMAN
GEOGRAPHY)QUESTIONS AND ANSWERS.
In the last 10,000 years: - humans began modifying the land surface for growing food with
advent of agricultural revolution
The agricultural revolution roughly - coincides with a warm interglacial period that began
@#
about 11,700 years ago which is called the holocene era (warm stable climate)
#$%^&*( $%^
&*()
The last 270 years of the holocene ushered into the - industrial revolution when climate
pollution began to increase dramatically
The industrial revolution was powered by - fossil fuels
What began after world war ii? - the great acceleration (1950-present)
-caused depletion in the ozone layer
-after 1950, the biodiversity of species started decreasing and the extinction of species
accelerated
The great acceleration marks the beginning of - homo sapiens' truly massive global imprint
on the planet
-the climate has already warmed by 1°c since 1900.
-if humans continue with business-as-usual consumption of fossil fuels, the warming
between 1900 and 2100 could exceed 4°c.
The greenhouse effect. - it is this trapping of heat energy that otherwise would have
escaped to space through the atmosphere
-allows solar radiation to enter
-the blanket effect
Is the greenhouse effect real? - -satellites routinely measure the incoming solar energy and
the outgoing heat energy from the planet
-independently, the heat energy emitted by the surface has been estimated using observed
surface temperatures on land and sea.
Aerosols - -visible smoke and smog are made up of tiny particles
-carbon dioxide and other greenhouse gases cannot be seen by the human eye
-most of these aerosols reflect sunlight and have a cooling effect
, WGU D199 SUMMARY AND TEST(INTRODUCTION TO PHYSICAL AND HUMAN
GEOGRAPHY)QUESTIONS AND ANSWERS.
Black carbon aerosols (a major component of soot) - -absorb solar radiation entering the
atmosphere and have a warming effect.
-warms the climate by absorbing solar energy rather than infrared energy from the planet
@#
Super pollutants - -non-carbon dioxide greenhouse gases and black carbon particles
$%^
-per molecule, their warming effects are much#$%^&*(
larger than that of carbon dioxide.
&*()
The northern hemisphere has warmed more than the southern hemisphere, largely
because - the ocean's influence
At current emission growth levels—that is, under a "business as usual" scenario - -another
trillion tons of carbon dioxide will be added to the atmosphere by about 2030
-at that point, the rate of climate change will be three times faster than the pace
experienced until now.
-unchecked emissions will lead to warming that could exceed 4°c
Earth is now experiencing the anthropocene era - -which means a time when
environmental change is driven by human activity
-one result of the anthropocene era is the increase in the greenhouse effect, which might
be better termed the "atmospheric blanket."
Vidence that human activity is the primary cause of global warming includes - physical and
satellite observations and the confirmation of the predictions of scientific models.
How are satellites and weather balloons used with climate change model data? - to
confirm predictions
Why is global cooperation necessary to reduce the effects of increased carbon dioxide in
the atmosphere? - gases travel quickly through the atmosphere to all parts of the globe.
Which phrase describes a change that would reduce the climate effects of methane? -
increase in sustainable agriculture
The cdm has two primary goals: - 1) to promote sustainable development in global south
countries
2) to allow industrialized countries to earn emissions credits from their investments in
emission-reducing projects in the south.
