1. Teaching Children about Climate Change
Five Short Similes for
Teaching Children about Climate Change

2. Background “Everything should be made as simple as possible,
but not simpler “” Albert Einstein
One way to simplify a complex processes, event or condition is to use a simile
Similes are basically just short stories that relate one thing
(e.g., object, event, place, person) to another thing. In this
lecture, we will relate something complex (i.e. climate change
and climate change impacts) to something simple to make it
easier to understand and remember

3. Lecture Objective To use a five short similes to help explain
a few of the key components of climate change,
and climate change impacts on ecosystems

4. Five Similes for this Lecture
The (REALLY) Big Blanket
Steve’s Hill Slope Stairs Project
A Clint Eastwood Movie
My Brothers Car
Last Great Act of Defiance*
* Not classroom suitable

5. The (REALLY) Big Blanket Factory
Simile 1:
The (REALLY) Big Blanket Factory

7. Think of the burning fossil fuels like making billions of blankets to go up into the sky

8. Once the blankets are made, the are transported up into the sky (think atmospheric FEDEX)

9. The more blankets, the more the heat trapped underneath (just like on your bed)

10. How warm would you be if you doubled the number of blankets on your bed and crawled underneath them?

12. But that’s only half the story….

43. BLEACHING OF CORAL REEFS BY OCEAN TEMPS > 85deg F (29 deg C)

44. Locations of Coral Reef Bleaching

45. Simile 4:
My Brothers Car

46. A car should have its oil changed every 3000 miles. If you
wait until 5000 miles its probably still OK. If you wait until
30,000 there will probably be some damage done to the
cars engine, but it can probably be fixed even though it will be
expensive. If you wait until 100,000 miles, the car will
probably be broken and very, very expensive to fix, or
it may not be fixable at all.
Global warming is the same way, the longer we wait, the
More expensive it will be to fix (if at all).

47. The Last Great Act of Defiance

49. RECYCLE!!!

50. Tell your parents what you learned!!
There is still some wrong information that is being
passed around about climate change and its impacts.
You can help to educate your parents with the truth
about climate change.
Why is wind energy gaining so much momentum? Spiraling utility bills, the need for uninterrupted service, the high cost of accessing the utility’s electric grid from a remote location, and concerns over environmental impacts are leading to the rush to residential wind systems. Reducing dependence on potentially volatile electric prices is another key motivator for many home-scale windsmiths.
Depending on the local wind resource and utility rates, a small wind energy system can reduce a customer’s electricity bill by 50% to 90%. It can be installed as a stand-alone system, eliminating the high cost of extending utility power lines to a remote location, or it can be connected to the power grid, enabling the customer to sell excess power to the utility or buy additional power as needed. Over its 20- to 40-year life, a small residential wind turbine can offset approximately 1.2 tons of air pollutants and 200 tons of carbon dioxide and other “greenhouse” gases. And it can do so at one-third to one-half the installed cost of the most competitive solar electric technology.
