The industrial activities of mankind are fundamentally altering the Earth's atmosphere with society altering consequences.
These slides present the fundamentals of human driven global warming and climate change, show how the effects of climate change are already have a significant impact on both human and ecological systems, and clarify why urgent action to address the most challenging issue facing us today is an absolute necessity.
The solutions to climate change are within our grasp and present world-altering possibilities. But it will take will power and a globally coordinated effort to make them a reality.
1. Earth: Our Life Support System
How human-driven climate change is impacting
our world and what we can do about it
2. Scuba divers rely on a life support system to survive in a
beautiful but hostile surrounding.
A sudden change to that system
can be life-threatening…
…We’re now making sudden changes
to our own life support system.

…will be a lot like our past

build…
..what food we grow…
Climate is not the same as weather. Weather
helps us decide what clothes to wear. Climate
helps us decide what clothes to buy.
8. Some scientific conclusions or theories have been so
thoroughly examined and tested, and supported by so many
independent observations and results, that their likelihood
of subsequently being found to be wrong is vanishingly
small. Such conclusions and theories are then regarded as
settled facts. This is the case for the conclusions that the
Earth system is warming and that much of this
warming is very likely due to human activities.
– U.S. National Research Council
10. “Man-made”
Global Warming
Certain industrial activities of
mankind including…
Fossil fuel power production
Automobile combustion
Deforestation
…and many more
Have fundamentally changed the
composition of Earth’s
atmosphere.
These atmospheric changes have
increased the Earth’s greenhouse
effect and altered the global climate
with significant impacts on both
human and ecological systems.
11. Five Key Points to Discuss
The greenhouse effect is vital to the Earth’s climate
Carbon dioxide (CO2) is vital to the greenhouse effect
Human activities are significantly impacting global CO2 levels
Changes in climate can have significant detrimental impacts
There are significant opportunities in solutions
13. The Greenhouse Effect
Greenhouse gases in the
atmosphere trap some of this
heat, keeping the Earth warm.
Some becomes
heat.
Some sunlight
is reflected back
into space.

Despite being further from the Sun, Venus gets
hotter than Mercury thanks to its dense atmosphere
and immense greenhouse effect.

be a frozen ball of ice, floating in space.
The troposphere extends only
about 12 miles above the
Earth’s surface at its
maximum…
…thinner than an apple’s skin
20. OK. So, the greenhouse effect is important.
But how important is carbon dioxide (CO2)
to the greenhouse effect?

Unlike water vapor, CO2 gets well
mixed throughout the atmosphere
26. The Game Of The Rules
Heat Plinko • All heat leaving the surface must eventually
Desert Earth Surface Jungle return to space
• The longer heat takes to escape, the warmer a
region can become on average
• Carbon dioxide “pegs” get evenly distributed
throughout the atmosphere
Earth’s Atmosphere
• Water vapor “pegs” vary both laterally and
vertically in the atmosphere
• As greenhouse gases, both water vapor and
carbon dioxide delay heat escaping to space
• Heat can be reemitted
in any direction
• Additional carbon
dioxide can remain in
the atmosphere for over
100 years
Space Result: The effects of additional carbon dioxide
are felt everywhere for a very long time

the level of CO2 in the atmosphere?

for 800,000 Years
“Generally accepted modern understanding of the global carbon cycle
indicates that climate effects of CO2 releases to the atmosphere will
persist for tens, if not hundreds, of thousands of years into the future.”
- Archer et al., Annual Review of Earth and Planetary Sciences, Jan 2009

35. Checkpoint
The greenhouse effect is vitally important to the Earth’s climate
This greenhouse effect is provided by an incredibly thin atmosphere
Over 97% of the atmosphere has nothing to do with this effect
Water vapor and CO2 are the primary natural greenhouse gases
Water vapor is far too short-lived to drive long-term climate
CO2 levels can remain elevated for hundreds, even thousands, of years
The effects from CO2 on the atmosphere are both global and long-term
Human actions have risen CO2 levels by 40% in just over 100 years
37. Scientific evidence strongly indicates that natural influences
cannot explain the rapid increase in global near-surface
temperatures observed during the second half of the 20th
century…A particular concern is that atmospheric levels of
carbon dioxide may be rising faster than at any
time in Earth’s history…
