Visualizing The Atmospheric “Greenhouse” Effect Global Warming is real, but how much is due to human activities and how big is the risk? Presented to The Villages Philosophy Club 3 January 2014 by Ira Glickstein

2. X X VISIBLE LIGHT VISIBLE LIGHT How Does a Real Greenhouse Work?
A greenhouse stays warm MAINLY because it is airtight and insulated.
The walls and roof STOP CONVECTION and CONDUCTION of Heat Energy!

A Physical Analogy

Molecules and Photons
Light and Heat

4. Intergovernmental Panel on Climate Change (IPCC)
The Atmospheric “Greenhouse” Effect and Global Warming are Real, but not a Big Deal
I wrote the “VISUALIZE” series of postings to help some of the skeptics at Watts Up With That? understand the basic physics of the Atmospheric “Greenhouse” Effect.
I accept that Global Warming since 1880 is at least 0.5°C (1°F). IPCC claims about 30% more warming (1.5°F).
+0.6°C (2014)
Intergovernmental Panel on Climate Change (IPCC)
+ 0.8°C
(+1.5°F)
-0.2°C (1880)

6. The Atmospheric “Greenhouse” Effect and Global Warming are Real , but not a Big Deal
PART OF THE WARMING IS DUE TO HUMAN ACTIVITIES THAT HAVE INCREASED CO2 AND CONTINUE TO DO SO.
However, MOST of the warming is due to NATURAL CYCLES not under human control.
The IPCC has overestimated the effect of increasing CO2 by a factor of two or three.
That is why Global temperatures have stabilized for the past 17 years even as CO2 continues to increase.

22. The Top of The Atmosphere is about -1°F.
-33°F BELOW FREEZING. But the Earth Surface is about 60°F.
THANKS to the Atmospheric “Greenhouse” Effect!

23. The Atmospheric “Greenhouse” Effect Warms the Earth to Life-Supporting Temperatures
Absent the Atmospheric “Greenhouse” Effect, the Earth surface would average about -BELOW FREEZING. Too cold for life.
The WARMING EFFECT OF “GREENHOUSE” GASES IS ABOUT 60°F. THANK GOODNESS!
Since 1880 Atmospheric CO2 is up about 40% (from 280 to nearly 400 ppmv). Mostly Human caused.
Global Warming added about 1°F (or 1.5°F if you believe the IPCC)
