The present level of atmospheric CO2 concentrations and the results of ice cores undisputedly illustrate the unprecedented historic levels of greenhouse gases. In general anthropogenic sources and in particular the global power sector, which generates around 40% of all global electricity from coal, is blamed for this rise and actions needs to be taken on an international basis as to combat with this fact. But are we certain about the sources of greenhouse gases?

Our iconoclastic hypothesis is being initiated with the contact of desert dust and cloud water. Here we show that that during the course of long-range transport of desert dust under the influence of meteorological events the dust particles has a chance of interacting with cloud water. Upon this contact dust particles becomes wet and the prokaryotes embedded within the clay structure becomes active within minutes and they produce oxalate as an osmosolute.

Oxalate, assists prokaryotes to attach themselves on to the clay mineral structure and eventually leads to formation of iron oxalate via combining with iron bearing mineral lattice. If the solar irradiation is above a threshold level that is assumed to be 200 Watt/m2 then, through decarboxylation reaction iron oxalate dissociates by forming reduced iron carbon dioxide and carbonyl radicals. We further propose that the decomposition of the outer shells of the fungi's, i.e., chitin, further decomposes via the action of oxalate leading to the formation of amine groups as well as methyl radical hence methane, within clouds under oxic conditions.

Despite clear measurements that can be accessed through the data archive at WMO/WDCGG or CARBOEUROPE or recent ICOS stations this fact has been and still being ignored artificially on a global basis simply because the rate of CO2 or CH4 increases during such transport events are inevitably above the empirically set limits by World Meteorological Organization/World Data Centre for Greenhouse Gases. We are luck that this empirically set limit is not been applied to CARBOEUROPE or ICOS stations so that we can illustrate the impact of desert dust cloud interactions through the available data set.

Though we have our own measurements and analytical results as to support our iconoclastic theory we based on the results gathered and archived by other well established monitoring stations backed up by satellite imageries and backtrajectory analysis as to illustrate the impact of desert dust cloud interactions and its impact on atmospheric greenhouse gases.

Thus without assessing the impact of this so far unaccounted natural source it's impossible to impose and expect any positive outcome from any international agreements as to combat with the adverse effects of these gases. Once realized and accepted, GCM's algorithms should immediately also adapt this in cloud production of this natural source as to account realistic predictions.
