UV Radiation and biogenic methane coupling

In an interesting paper I. Vigano et al 2008,we see the instantaneous emission of ch4 from plant under controlled uv irradiance.This is plants release ch4 as a defensive response to increased uv irriadiation.(ch4 being an important atmospheric sink and part of the ozone nitrogen cycle).

As we have seen here, there are a number of ways the sun effects climate

. -A change in the solar constant of (wavelength) irradiance output.
-Changes in ultraviolet irradiance that modulates temperature, atmospheric chemistry, and climatic dynamics such as precipitation and cloud formation .
-Indirect and indirect influences by solar radiation and cosmic radiation(galactic)
-Changes in magnetic and gravitational constants(solar).
-Changes in magnetic connections heliospherical couplings

The biospheric response is another indirect coupling to fluctuations in exogenous forcing. These experiments were first performed by the Russian biophysicist Alexander Gurwitsch. Here in 1923 he first observed biophotons or ultra-weak biological photon emissions; weak electromagnetic waves which were detected in the ultra-violet range of the spectrum.

Abstract. The recently reported finding that plant matter and living plants produce significant amounts of the important greenhouse gas methane under aerobic conditions has led to an intense scientific and public controversy. Whereas some studies question the up-scaling method that was used to estimate the global source strength, others have suggested that experimental artifacts could have caused the reported signals,

and two studies, one based on isotope labeling, have recently reported the absence of CH4 emissions from plants. Here we show – using several independent experimental analysis techniques – that dry and detached fresh plant matter, as well as several structural plant components, emit significant amounts of methane upon irradiation with UV light and/or heating. Emissions from UV irradiation are almost instantaneous,

indicating a direct photochemical process. Longtime irradiation experiments demonstrate that the size of the CH4 producing reservoir is large, exceeding potential interferences from degassing or desorption processes by several orders of magnitude. A dry leaf of a pure 13C plant produces 13CH4 at a similar rate as dry leaves of non-labeled plants produce non-labeled methane

This puts the “carbon offsets community” in a rather fraudulent industry
