Light and Heat - The Greenhouse Effect: Video

I've created a video entitled Light and Heat - The Greenhouse Effect. 
It’s a pictorial explanation of the greenhouse effect. Gases in the atmosphere, such as carbon dioxide, that absorb heat radiation, then re-emit it, serve as greenhouse gases. The notion of a one-way Carbon Arrow of carbon from fossil fuels in the earth to extra carbon dioxide in the atmosphere is set out. Additionally a Carbon Dioxide Bathtub is a good model for the accumulation of extra carbon dioxide in the atmosphere.

Please have a look!

This video expands on material I’ve previously posted here:

Light And Heat – The Greenhouse Effect and The CO2 Bathtub. 
This is the second in a series of videos that also includes:

We Need to Begin Abatement of Greenhouse Gas Emissions Right Away

Image
Summary .   The Intergovernmental Panel for Climate Change (IPCC) has issued four climate Assessment Reports between 1990 and 2007, warning about the perils of emitting greenhouse gases and the resulting global warming and its impacts on human society.   These phenomena originate largely from humanity’s burning of fossil fuels.   The dangers include higher global temperatures, regionally dependent worsening of heat waves and drought, or rainfall and flooding, and sea level rise with attendant worsening storm surges. The Assessment Reports and a recent article by Stocker point out that embarking early on mitigation measures makes it easier to constrain the overall warming and its attendant harms to humanity, whereas delay removes the easier paths of mitigation from consideration and requires more stringent, more expensive mitigation to be undertaken  later to make up for the opportunity lost by not starting earlier. It is concluded that an important way forward cou...

President Obama’s Clean Power Plan to Reduce Emissions

Image
The Administration’s Clean Power Plan will significantly reduce greenhouse gas emissions from the electric power industry over the next fifteen years.   Global warming affects all humankind .   Changing weather patterns, consisting of greater and more frequent weather extremes have become more and more common in recent years and decades.   Around the world, extreme rains and floods, droughts and unprecedented sea level rise have occurred in ways that we are now accepting as being “new normals” of weather which humanity did not experience in earlier years.   While we cannot point to individual events as being caused by global warming, the frequency of occurrence and patterns around the world are all consistent with the predictions that global warming will worsen extremes of weather and climate going forward.   The warming arises because of humanity’s burning of fossil fuels for energy as well as from other human activities, not from any natural cycling of cli...

The U. S. National Climate Assessment: Effects of Warming and Measures to Counteract Them

Image
Summary . The Third U. S. National Climate Assessment, a federally mandated project, reports on the current status of global warming in the U. S. and its harmful effects on the population and the environment.   As a result of manmade emissions of greenhouse gases, damages resulting from harsh warming events and extreme weather events have been worse than in earlier periods.   They are projected to be become even more severe by the end of the present century in the absence of meaningful action to combat them.   Mitigation and adaptation measures are available and need to be implemented to limit further warming and its harmful effects by 2100.   Important procedures involved in combating further warming include risk assessment and evaluation, and iterative (cyclical) sequences of planning, decision-making and implementation of projects, coupled with critical analysis of steps in these processes along the way.   Applying the results of such analysis back to opti...
