Greenhouse gas Definition and 15 Threads

Experience in the fertilizer industry, with focus on environmental issues and energy recovery, clean technologies, process design and simulation, GHG balance. Published several studies on low carbon technologies as well as on Kyoto Protocol Communications.

The international Journal of Greenhouse Gas Control. It has an Impact Factor of around 4, but what's the perception? Is it respected? Is it considered a good journal? There isn't a qualitative judgment online. My boss seems to look down on it, but it has a good impact factor.

Are there multiple sources for an emissions inventory? For instance, how debated is the UNFCCC GHG inventory? (http://unfccc.int/ghg_data/items/3800.php) And is there any international inventory that has an emissions breakdown like the Australian governments? (http://ageis.climatechange.gov.au/#)

Dear PF Forum, Why nobody ever thinks of terraforming Venus? Many propose Mars, even as far as Europa (not the continent!) or Titan. Mars has very little atmosphere compared to Earth. Titan has thick atmosphere but too cold. I once read that Carl Sagan proposed the idea by spreading bacterias in...

I'm have armchair interest in greenhouse gases. One of the interesting points is the amount of greenhouse effect that CO2 has versus water vapor. I go to this page http://www.climate4you.com/GreenhouseGasses.htm and find that the relative percentage of atmospheric humidity is 45%. I...

Hi everyone, This is my very first post here, so hi! I've got a few questions about CO2 that maybe a physics buff can help me out with. I understand the basics about CO2 warming the atmosphere via absorption and re-emission (radiatively or kinetically) of Outgoing Longwave Radiation...but...

Okay so I am a first time poster, hello to my fellow scientists. I need an expert opinion on a simple question I can't get around: I understand that Carbon Dioxide will absorb more energy from whatever radiation it comes into contact with than, say, Oxygen. That being said, I imagine the...

I recently came across several apparently reputable sources (e.g., NASA, PBS) that describe a simple, elegant experiment intended to demonstrate carbon dioxide's role as a greenhouse gas. Each of them involves two sealed containers with thermometers - one containing air, the other containing...

Atmospheric gases play a role in planetary temperature regulation Carbon dioxide levels have been rising rapidly in the Earth’s atmosphere and are linked by the IPCC to “global” warming. Recent failure of measured temperatures to advance with increasing carbon dioxide has called this assertion...

Hungarian scientist Ferenc Miskolczi has discovered the greenhouse gas equation Arthur Milne developed in 1922 contains a serious flaw. Milne mistakenly solved the differential equation involved by assuming an infinitely thick atmosphere. Miskolczi was working for NASA at the time and NASA...

is it true that there are more greenhouse gasses released from a single Volcanic eruption than all of the gasses produced by man since the industrial revolution? If so, shouldn't that silence the global-warming advocates?

[SIZE="4"]How the Greenhouse Gas Effect Works We all know by now that the greenhouse gas effect depends upon absorption by greenhouse gas molecules of infrared energy radiated from the Earth’s surface, and which is then re-radiated by these molecules in all directions. Effectively, half the...

Greenhouse Gas Effect and Carbon Dioxide I have been having some difficulty with this, so perhaps someone could please sort out any mistakes, and let me know. Consider a vertical column of the Earth’s atmosphere based on a square of area 1 m^2. This air column has a mass of 1.01×10^4...

Hello all It seems that water vapour doesn't figure in greenhouse gas calcs & global warming. This site claims.. "Water vapor overwhelms all other natural and man-made greenhouse contributions." http://www.clearlight.com/~mhieb/WVFossils/greenhouse_data.html Are they right ? cheers

Ok, here's the question. Without the greenhouse gases in Earth's atmosphere the temperature would be 250K. With them it is 40K higher (290K). Using the Stefan-Boltzman equation for flux ( F = σT4) what is the percentage of infrared radiation leaving the Earth's surface taht is...
