Agrobiologist and scientific researcher Dr. Albrecht Glatzle, author of over 100 scientific papers and two textbooks, posts at WattsUpWithThat: “Our key conclusion is there is no need for anthropogenic emissions of greenhouse gases (GHGs), and even less so for livestock-born emissions, to explain climate change. Climate has always been changing, and even the present warming is most likely driven by natural factors. The warming potential of anthropogenic GHG emissions has been exaggerated, and the beneficial impacts of manmade CO2 emissions for nature, agriculture, and global food security have been systematically suppressed, ignored, or at least downplayed by the IPCC (Intergovernmental Panel on Climate Change) and other UN (United Nations) agencies."


But, this should be read with the Allison-Sheahen paper (see link below). The WUWT article argues that the amount of methane emitted by animals is greatly overstated by the IPCC, and there isn't very much methane.The Allison-Sheahen paper explains that no matter how many animals there are (or how much methane), the realities of the infrared spectrum and the way competing molecules (especially H2O) absorb photons makes CH4 (methane) completely irrelevant.
