Be afraid, be very afraid!!!!

HuffPo:

Average global levels of carbon dioxide stayed above 400 parts per million, or ppm, through all of March 2015 — the first time that has happened for an entire month since record keeping first began, according to data released this week by the National Oceanic and Atmospheric Administration (NOAA). Scientists with NOAA’s Earth System Research Laboratory have called the news a “significant milestone” in the growing scourge of man-made climate change. “This marks the fact that humans burning fossil fuels have caused global carbon dioxide concentrations to rise more than 120ppm since pre-industrial times,” Pieter Tans, lead scientist of NOAA’s greenhouse gas network, told The Guardian on Wednesday. “Half of that rise has occurred since 1980.”…this week’s news stands as an irrefutable reminder that our planet is going through a process that could eventually cause harm to countless numbers of people.

OK class, please repeat; at the 400 ppm the Huff Po is screaming about, air is 1950 parts nitrogen, 524 parts oxygen, 23 parts argon, and one itsy-bitsy teeny-weenie part CO2. Yawn.

    Another way of putting it:

    “It took nearly a century to raise atmospheric CO2 concentrations from 3 parts per 10,000 to 4 parts per 10,000. That’s right, nearly a century to add 1 molecule of CO2 to every 10,000 molecules of atmosphere.”

    Let me attempt to define what constitutes a ” greenhouse gas ” . …as I have never seen it done in any discussion of global warming . I am assuming that it infers …any gas constituent that impedes radiative transfer . Thus , the big Two oxygen ( O2 ) and nitrogen ( N2 ) do not and that is an inherent physical characteristic of diatomic molecules . Sun light sails through these gases without an afterthought . On the other hand , so called , triatomic molecules ( CO2 ) do mask radiative transfer . However , always omitted from these discussions is the most plentiful greenhouse gas , water vapor H2O . … another triatomic ,bad boy , molecule .Now there are varying amounts of H2O present in the air …depending on where you live and the relative humidities ( RH ) associated with local climate . So lets use an average RH , say , 50 % . At that value the ratio of H2O / CO2 = ~ 27 . Here in North Carolina in the summer it is much higher . In Las Vegas , much lower . Now what in the world are we to do about water vapor in the air which is by a wide margin …is the most plentiful and hence ” dangerous ” greenhouse gas of all ?

    I sure would like to see a discussion by a really great scientist like Al Gore to elaborate on these concerns of mine about the need for H2O reductions and the potential for water vapor credits to do it . Clearly lots to learn here and perhaps money to be made by someone of his caliber ( ? ) . Gosh , maybe I could get involved too .

    Monatomic and homonuclear diatomic molecules are virtually unaffected by infrared energy; consequently, nitrogen, oxygen and argon are not greenhouse gases. Greenhouse gases, those that absorb and emit infrared radiation, include water vapor, carbon dioxide, methane, nitrous oxide and ozone, each with its own thermal footprint. Carbon dioxide constitutes about a fourth of the greenhouse effect. Small changes can have a significant effect on global mean surface temperature.

    I agree, albert boyers, the public has not gotten sufficient warning about the numerous dangers of dihydrogen monoxide. Although this environmental menace is beginning to subside in California and other parts of the western United States.

    albert boyers: However , always omitted from these discussions is the most plentiful greenhouse gas , water vapor H2O

    That’s precisely false. Atmospheric water vapor has been part of the theory of the greenhouse effect since Arrhenius. See Arrhenius, On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground, Philosophical Magazine and Journal of Science 1896.

    CO2 is a greenhouse gas. As it warms the Earth, it increases evaporation, which results in a further warming. Water vapor amplifies the effect of CO2. A doubling of CO2 will directly contribute to about a 1°C increase in surface temperature. Various studies have shown that the effects of water vapor will increase this warming to about 2-4°C, which is called climate sensitivity.
