I often feel there is difficulty in finding or locating the latest on climate change ie increasing methane, ice loss, feedback loops etc.
This overview by Sam Carana holds up well, succinct and eminently digestible for the layman; I am a layman. http://arctic-news.blogspot.com/p/extinction.html
It illustrates the stacking pernicious influences which in themselves arithmetically ensure sufficiently our downfall and even for this guaranteed scenario Sam Carana plays a light touch re the inevitable compounding and accelerating positive feedback loops that will push us into a whole new series of situations. Its all a quite dire mix, highly ironic as its mainly the consumption of oil and gas from ancient diatoms that has led to our demise, taking away the fundamental first layer of oceanic food chain and 20% of the worlds CO2 >O conversion. And yet no-one has ever seen a diatom with the naked eye.
I think I’m correct in saying it was independent scientist James Lovelock that discovered the gas DMS a product of oceanic plankton and its importance. I suggest read his autobiography, an instructive blend of practical science, talent and an independent thinking mind.
Sam Carana in a more recent post highlights the disregard paid by the latest IPCC (Sept 2019) briefing / report in which NO FIGURE IS QUOTED for the effects of subsea methane in its three forms, frozen hydrates, microbial, capped gas deposits. The IPCC are criminal in this neglect. However not as criminal as donald trump in the rolling back and eradication of decades of wise strategies to husband the planet more sensibly; but of course trump would know nothing of the natural world.
