If you cannot tell, my favorite book. I read recently that individual species extinction events has reached critical levels where we will shortly experience cascading ecological collapses. I will attempt to find said article and post it, or at least the important aspects of it.

Casual correction: an artifact is something Indiana Jones finds. Artefact is an artificial product or effect observed in a natural system, especially one introduced by the technology used in scientific investigation or by experimental error.

There's nothing fundamentally wrong with people. Given a story to enact that puts them in accord with the world, they will live in accord with the world. But given a story to enact that puts them at odds with the world, as yours does, they will live at odds with the world. Given a story to enact in which they are the lords of the world, they will ACT like lords of the world. And, given a story to enact in which the world is a foe to be conquered, they will conquer it like a foe, and one day, inevitably, their foe will lie bleeding to death at their feet, as the world is now.

The world’s seabirds are being pushed to the brink of extinction by the fishing industry which is competing with them for food, a new study has warned.

Populations have dropped by up to 70 per cent since the middle of the 20th century, experts said.

One of the most interesting reads on the ASIF. Thanks for posting Vox.

Does raise some serious concerns about how we would handle a true global epidemic like Clade X. Recently read The Year of the Flood by Margaret Atwood, very similar concept but the manufactured disease in the book has a much higher virulence and lethality resulting in true collapse.

or more correctly imv “the frog went extinct because the bio-diverse habitat it depended on went extinct”

Frogs need a lot more than just food.

Of course they do. Pedantry for pedantry's sake. I was attempting to simplify the obviously complex message.

I would agree that most of your consequences are not a result of climate change.  Hence, any action that addresses climate change will have little to no effect on them.

My point was simply that it is too late, much too late. At a certain point the species becomes functionally extinct or extinct in the wild.
Hypothetically the world gets around to addressing CC by 2030. That is too late. We missed the boat by 20-30 years from today.


Edit: Misread Klondike's reply, believe him to be agreeing with me.  :-[ :-X

So yes, addressing climate change does not mean we broadly address environmental problems. Okay, hypothetically we go carbon free, but did we stop fragmenting ecosystems? Damming rivers? Using pesticides? Of course not.

It is important to remember that we are not just talking about individual species going extinct, but the collapse of entire ecosystems.

Again pertaining to the arcticle that the video is based on: they mention that humans are more likely to notice the secondary extinctions rather than the primary. I.e we see the frog that went extinct instead of “the frog went extinct because the food it depended on went extinct”.

And of course by that point it is too late.

There's a chance we can live without a major disruption in a world practically devoid of wild life because our main crops are pollinated by the wind.

Is this just looking at insect collapse? Ignoring the quality of life changes that would result from extinction of pollinators, there is too much coming together all at once for humans to not be massively impacted.

If we look 10-20 years in the future we will be facing: Ice free arctic, global warming/climate change, sea level rise, ocean acidification, fishery collapse (already ~90% in past 50 years), terrestrial animal collapse, insect collapse, amphibian collapse, habitat decimation and fragmentation. It is simply too much that will occur, or has already occurred, all at once in such a short time span. Each of these has its' own cascades and resulting impacts.

And if you read the article that the above video was based on, you would see recommendations that are short sighted and frankly inappropriate. For instance, one of the experts recommended increased reliance on fishing to feed growing populations if complete pollinator collapse occurred. Well how is that supposed to work if we have already seen declines of up to 99% of some of the staple fish.


I will concede that using the broad brush of climate change as the only reason for declining populations is premature. More likely to be habitat destruction and fragmentation, declining fertility rates, increased use of pesticides, etc. Of course climate change is likely to be an additional stressor placed on insect populations.

Arctic sea ice / Re: Arctic Ocean 'acidifying rapidly'
« on: October 30, 2018, 01:42:28 AM »
It has been mentioned in other threads but I feel it pertinent to bring up once again:

The Sixth Extinction: An Unnatural History has an entire chapter on ocean acidification. We have seen that as oceans become more acidic, the species counts drop exponentially. This has been measured directly by studying thermal vents that produce CO2 and the species that are within certain ranges of those vents.
So in layman's terms: as the ocean becomes more acidic, less species live there.

To my elderly eyes it appears that, in both area and extent, this is likely to be the first time in the satellite record that the autumn local maximum is lower than the summer one. Am I right?


Actually 2016 was the first to do this, and did so for both extent and area.

Probably already mentioned somewhere else "The 6th extinction" written by The New Yorker' scientist journalist Elizabeth Kolbert -released in 2015- is excellent, and the link with climate change is also very well articulated

Yes, really laid out how bad things will be when the mix of climate change, ocean acidification, fishery collapse, deforestation all to come to a head.

Arctic sea ice / Re: Freeform season chatter and light commentary
« on: August 09, 2018, 09:29:00 AM »
I would just like to point out that the common misconception "sea ice melting will not raise sea level" is just so, a misconception.

The paper The melting of floating ice raises the ocean level by Peter D. Noerdlinger and Kay R. Brower, circa 2007. The paper was published in Geophysical Journal International.

The two key quotes: "It is shown that the melting of ice floating on the ocean will introduce a volume of water about 2.6 per cent greater than that of the originally displaced sea water." and "If all the extant sea ice and floating shelf ice melted, the global sea level would rise about 4 cm."

So while the complete melting of all arctic and antarctic sea ice would result in a negligible (compared to Greenland and Antarctica) 4cm rise in global sea level; we know that this could not take place as even with a BOE in the arctic, we would have another 18+million KM^2 in the antarctic.

https://academic.oup.com/gji/article/170/1/145/2019346 -- the full paper for those interested.

As many times as I’ve seen ASIF mentioned on Reddit, my heart was broken today when I saw a screenshot I knew I recognized from the melting season thread on r/ClimateSkeptics

The quote in question:
Can anyone explain me how it is possibble that the past 3 winters were the warmest "ever" in the Arctic and yet summers are not much to talk about. Where does the extra heat from winter go? Why does it not show up in big extent losses later on?

People who keep posting that it will be a "normal (2010-2017)" year are blowing my mind. I really don't get it how it will get warmer  for years on end in the ocean and the atmosphere but the ice is supposed to just chill...

Massive systems are hard to predict. Tons of individual events can accumulate to prevent an open ocean in September

Maybe I am missing something, but that Slater projection for July 25 looks a lot more like the current ice extent from AMSR2 for June 5 (today) than it looks like, for example, the actual ice extent for July 25 last year (see below -- I've put all three maps together).  [snip]

I believe you are correct and will attempt to contact UofC once again with our collective concerns. Thank you for paying closer attention than I was!

Slater projection shows ice beginning to open in the CAB for July 25th, extremely close to the pole. Extent of 7.42 mil km^2 at that time.

Edit: foolish me, the CAB is already opening thanks to significant torching. I believe the extent graph to be correct but the actual map to be today's date rather than a forecast 40 days out. I will contact UofC once again.

I think it is worth noting that this is the closest global sea ice has been to the previous year since (record lows) since the divergence of 2017 and 2016 in October.

AND will 2018 be the year that global sea ice extent dips below 16 million sq km??
