Turning Down the
Heat
The safe upper limit of CO2 in Earth’s atmosphere
What is 350 parts per million (ppm)?
These carbon-based substances are burned to
produce energy
What are coal, gas and oil?
390 ppm
What is the 2009 level of CO2 in Earth’s atmosphere?
Without these gases the Earth would be too cold for
human life.
What are Greenhouse Gases?
The international campaign to seek solutions for
Global Warming
What is 350 Degrees?
The liquid remains of dead plants and animals.
What are oil and gas?
Water flowing over a dam
What is Hydroelectricity?
Splitting of Atoms
What is Fission Nuclear Power?
These cells that collect and convert sunlight to energy
are made of silicon.
What are Solar Cells
OR Photovoltaic Cells?
Heat pumped from the ground to heat a space
What is Geothermal?
The number of years that a ton of Greenhouse Gas put into the atmosphere today
lasts
What is 100 years?
This gas is the byproduct of decaying garbage
What is Methane (CH4)?
The number of pollution emissions released
by a fuel cell car
What is ZERO?
The products of
a fuel cell power generator
What are energy and water?
The type of pump that moves heated water or air from within the Earth to the
surface, AND recirculates the cooler water and air back into
the Earth.
What is an Earth Loop Heat Pump?
Combustion of waste.
What is Biomass Energy?
This natural movement of air turns turbines
to produce energy.
What is WIND?
When waves move turbines to produce
energy.
What is Tidal Power?
The use of crops as
a fuel source.
What is Biofuel?
The type of nuclear energy that involves the
joining of atoms.
What is Fusion?
The average temperature Lake Superior has risen
since 1979.
What is 15OC?
These prevent water from evaporating from Lake Superior in the winter
What is ice and snow?
A process by which there is a net accumulation
of a chemical into
an organism.
What is Bioconcentration?
The storage and buildup of chemicals within the natural
tissues of one organism.
What is Bioaccumulate?
A food relationship in an ecosystem in which energy
and nutrients are transferred through a series of
organisms by each stage feeding on the preceding
one and providing food for the succeeding stage.
What is a Food Chain?
