by Veli Albert Kallio [ image by Peter Carter of Climate Emergency Institute ] We at Sea Research Society's Environmental Affairs Department are very concerned of the melting permafrost terrain and methane clathrate deposits of the Arctic Ocean's sea bed (which are seeding Siberia's air once again with carbon-12). This is because Arctic Ocean's methane clathrates, methane (CH4) & carbon dioxide (CO₂) deposits are thought to be the world's largest reservoir of carbon. When it comes to methane, much of that in the Arctic is a side-product of geochemical processes since the birth of our planet some 4 billion years ago and so it contains ZERO radiocarbon (14C). To these are added the various undersea and land-based deposits of ancient fossil carbon which too have zero or just minute content of carbon-14. We see already the Arctic at a tipping point, reaching a cliff edge to zero carbon-14 presence in tundra's plants emerging over recent years. Above should set...

By Andrew Glikson Earth and climate scientist Australian National University Since its inception the Paris Agreement has been in question due to, among other: its broad definition, specifically holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels; its non-binding nature; and  accounting tricks by vested interests. The goal assumes pre-determined limits can be placed on greenhouse gas levels and temperatures beyond which they would not continue to rise. Unfortunately these targets do not appear to take account of the amplifying positive feedback effects from land and oceans under the high cumulative greenhouse gas levels and their warming effects. Thus unfortunately the current high CO₂ levels of about 408 ppm and near-500ppm CO₂-equivalent (CO₂+methane+nitrous oxide) would likely continue to push temperatures upwards. Significant climate scie...
