A rebuttal to the cartoon video "The Global Warming Hoax Explained for Dummies" written by the Youtube user Vito Corleone
_______________________________________________________________________________________________________

+Zero Quanta Here is a point-for-point rebuttal of every idiotic point made in that garbage video you mentioned:

1) "I'm cold, therefore global warming isn't happening." The current weather in any given region is not indicative of climate trends.

2) "The climate goes through natural climate cycles." Of course it does. No one disagrees with this. What the facts and the evidence indicate is that the planet should be in a cooling trend, owing in part to a period of decreased solar irradiance. The climate is not in a cooling trend, it is in a warming trend. http://iopscience.iop.org/1748-9326/6/4/044022

3.) "Thinking CO2 raises temperatures is like saying raising umbrellas causes rain." This fails to understand the laws of physics governing heat transfer in the atmosphere. CO2 does not interact with energy at wavelengths above 4000 nM. It absorbs and reflects energy at wavelengths below 4000 nM. Energy arriving from the sun occurs at 4000 nM and above. Energy reflecting off the earth's surface occurs below 4000 nM, such that CO2 and other greenhouse gases absorb it and reflect some of it back toward earth, causing a warming trend. This process is governed by the laws of physics and is not open to debate. http://www.sciencemag.org/content/339/6123/1060

4) "There's not enough CO2 in the atmosphere." The mass of the atmosphere is 5.3 x 10^18 kg. 0.03% of this is carbon dioxide, which is trillions of tons. Every CO2 molecule continuing that 9 trillon tons is capable of facilitating an unlimited number of heat transfer events. That is why it is called a greenhouse gas. People who do not understand this do not understand the laws of physics. http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/grnhse.html

5) "Only 7% of total CO2 is from anthropogenic sources." The remaining 93% of naturally occurring CO2 emissions belongs to the earth's carbon cycle, wherein every natural atmospheric CO2 input exists in balance with an environmental carbon sink, such as the oceans and plant life. Anthropogenic emissions have no such offset, and such they are contributing to a build up of carbon dioxide in the atmosphere.

6) "If human carbon emissions were reduced to zero, it would not make a difference because of naturally occurring carbon emissions." Incorrect. See point #5.

7) "The greenhouse effect of carbon dioxide is very small. Water vapor is the main greenhouse gas." Incorrect. The heat-trapping physical properties of carbon dioxide warm the planet enough to allow liquid water to exist in all three states: solid, liquid, and vapor. Without this carbon dioxide, there would be no water vapor, only ice, and the earth would be frozen solid. People who think water vapor can occur without an existing greenhouse effect do not understand basic physics. http://www.nature.com/nature/journal/v519/n7543/full/nature14240.html

8) "Water vapor is the sole cause of the earth's greenhouse effect and CO2 is irrelevant." Incorrect. Without the greenhouse effect of CO2 and other greenhouse gases, no water vapor would exist on earth in the first place. Water vapor does not just magically appear.

9) "Methane is not a consequential greenhouse gas because there's not enough of it." There are hundreds of millions of tons of methane in the atmosphere, and each molecule represents an unlimited number of heat transfer events. Its mere existence in any concentration means that it contributes measurably to average sub-tropospheric temperatures. http://www.acsf.cornell.edu/Assets/ACSF/docs/attachments/Howarth-EtAl-2011.pdf

10) "CO2 comes after natural global warming." CO2 didn't initiate warming from past ice ages, but it did amplify the warming. About 90% of the global warming followed the CO2 increase at the end of the last ice age. http://www.nature.com/nature/journal/v484/n7392/full/nature10915.html

11) "Michael Mann fudged the data." Eight separate investigations found that no data manipulation occurred. One of these investigations was carried out by Pennsylvania State University, and concluded in its report: "there exists no credible evidence that Dr. Mann had or has ever engaged in, or participated in, directly or indirectly, any actions with an intent to suppress or to falsify data". All eight investigations reached similar conclusions. http://web.archive.org/web/20100704031346/views.washingtonpost.com/climate-change/post-carbon/2010/07/by_juliet_eilperin_a_pennsylvania.html

12) "Steven McIntyre exposed the CRU." Steven McIntyre and his cohort Ross McKitrick are not scientists, are affiliated with the fossil fuel industry, and receive funding for their activities from the industry. http://scienceblogs.com/deltoid/2005/08/08/mcintyre/
http://scienceblogs.com/deltoid/2004/04/28/mckitrick/

13) The ice core points about CO2 lagging temperature are just plain false. Again, external forces initiate warming, which in turn initiates the release of carbon gases which then accelerates the warming. CO2 has not been the root cause of natural warming in the past, but it is the root cause of anthropogenic warming happening now. Climate deniers do not understand the science. http://cdiac.ornl.gov/trends/co2/lawdome.html
http://www.sciencemag.org/content/326/5958/1394.abstract

14) "Rising carbon dioxide is a good thing." The negative impacts of CO2-driven global warming on agriculture, health, economy and environment far outweigh any positives. http://www.pnas.org/content/106/11/4133.full.pdf+html

15) "Carbon dioxide is not concentrated enough to directly affect human health." This is an absurd straw-man argument which only goes to show what an absurd pile shit this video is. No one has ever argued that anthropogenic CO2 emissions present an asphyxiation risk.

16) "It's the sun causing warming." Over the past 35 years of global warming, solar irradiance and climate have been on divergent trends. Furthermore, if the sun was responsible for global warming, we should see warming in the high atmosphere and the low atmosphere. Currently we are seeing warming only in the troposphere, below the level at which carbon dioxide settles. http://www.warwickhughes.com/agri/lockwood2007.pdf

17) "Without the greenhouse effect of water vapor, the earth would be 14 degrees colder than it is." In other words, without water vapor there would be no water vapor (only ice). Why does the earth have water vapor in the first place? It's because of naturally-occurring carbon dioxide facilitating a greenhouse effect which allows water to exist in all three of its physical states. Water vapour is also the dominant positive feedback in our climate system and a major reason why temperature is so sensitive to changes in CO2. http://www.pnas.org/content/104/39/15248.full.pdf

18) "Cosmic rays lead to more clouds and water vapor, which warms the earth." This is unproven hypothesis currently unsupported by the evidence. Hypothetically, an increasing solar magnetic field could deflect galactic cosmic rays, which could seed low-level clouds, thus decreasing the Earth's reflectivity and causing global warming. However, it turns out that none of these hypotheticals are occurring in reality. http://iopscience.iop.org/1748-9326/8/3/035049/article

The rest of the video reiterates its previous errors and then delves into its paranoid conspiracy theories about "global socialism", and is not worth my attention or anyone's attention.
