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.
Debate is perhaps not the best term but a useful search tag for google to pick-up on, action is more likely a better route. Yet here below is recent material to help us focus and realise we need action and fast.
From the above …
02:02 … Greenland ice loss id 8,500 tons per second… PER SECOND.
02:15 Half permanent arctic ice has gone.
09:20 How we will have to live and the 3 trillion that is half of what is present day subsidy to the fossil fuel industries that SHOULD be directed to carbon capture.
Author David Wallace-Wells in the above at 09:20 informs us that the IMF estimated world subsidy to traditional fossil fuel industries is approx 5.3 trillion annually; wheras a spend of 3 trillion could possibly completely neutrelise world carbon emission to zero by utilising carbon capture.
Here below is author David Wallace-Wells that when talking to scientists ‘off-the-record’ realised the disjoint between what scientists think and realise themselves and what is released to the public for general media / news consumption.
That in fact Donald J trump does in fact 100% agree climate change is well and truly altering this planet in his ludicrous desire to ‘buy’ Greenland. Its the same as his bizarre insistence on yet more ‘Border Wall’ when in fact sufficient exists already. trump is very much yesterdays man now but how long will the morally and ethically moribund Republicans shore him up, to prop a limp doll now totally irrelevant to the real world.
Instead of picking fights with the Chinese he should be thanking them for the huge profits generated in the West from buying from China as a low cost supplier.
trump is clueless utterly clueless, is fed just sufficient low brow notions and redundant glimpses of untruths from his backers to keep him dangling alive with a few pronouncements amid a whirring helicopter engine meanwhile behind closed doors the real destruction and roll-backs continue. All accusations trump has ever thrown at others are in fact applicable more accurately to himself, namely he IS the swamp.
Greenland proves trump knows fine well climate change is a huge vast engine of change that cannot be stopped. I write this post as unusually google / youtube is offering me better search results than usual ie reaching out of the Windows 10 bubble that is a restriction that arrived with this replacement stack a few months ago.
Below we are told Greenland has lost eleven billion tons of ice in one day and the sea worldwide rose half a millimetre in ONE DAY! Remember also that thermal expansion will raise ocean levels still further.
Note in the last two seconds of the vid below how all the river flow disappears down a hole to also erode and melt from below, as if Swiss cheese.
Not very often I can sit still to watch something beginning to end …
At 07:30 above we see most of Italy and the UK severely modified ie submerged merely with the loss of the western Antarctic ice mass.
At 15:00 … increased precipitation is predicted from the additional freshwater from melt which will accellerate further the melting rate, a continuous compounding of the problem. I quote … as freshwater evaporates faster than salt water there will be a lot more rain and fresh snow.
At 21:00 all life down in the Antarctic seems to depend on krill which to my mind immediately focuses on the necessity of diatoms. Yet again we do not specifically hear or see of them, yet diatoms are ‘the crux of the matter’. Diatoms are an utter fascination of mine, whether its Alfred Nobel and his dynamite, 70% of the worlds oil and gas, the symbiosis with or the collapse of coral reef ie the Bryozoans, Pacific seabird collapse … I believe all are diatom based. My wife always said i cannot have an encounter without getting diatoms into the conversation somewhere. Remember silica is also the base for silicon wafers /chips and so often i cannot find a specific acknowledgement of this connection. Ooops and the heat insulation on the Challenger / Shuttle …. all diatoms !
Without diatoms we are absolutely screwed. And the irony of what has lead to their demise is quite horrible ie the burning of fossil fuels which are mostly the end remains of diatoms. Realise also that the huge Pacific seabird dieoff has not been fully explained nor reported as sufficiently as it should have been.
At 43:30 land animals are blinded because of the hole in the ozone layer, the size of North America. Yet theres no mention of the work of James Lovelock in actually discovering and measuring the level of CFCs in the atmosphere. James Lovelock also discovered DMS as emitted by diatoms and diatoms are if my memory is correct responsible for 20% of the planets conversion of CO2 to O.
