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
-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.
Created by Kyoto Protocol
-Devised by the World Bank, it is slated to be a key component of any
post-Kyoto climate treaty - --Reducing emissions from deforestation and
degradation (REDD) is another offsetting mechanism
-REDD is intended to help Global South countries protect their remaining
rain forests and reduce the greenhouse gas emissions caused by
deforestation, forest degradation, and peatland destruction.
-Countries that reduce net REDD emissions below a preset baseline
would receive credits that could be sold in carbon markets and used by
purchasing nations to meet their international mitigation obligations.
-The Paris Agreement - --a global agreement that came into force in
2016 and builds on the U.N. Framework Convention on Climate Change,
