A few quotations and how even the ‘informed’ are still failing to comprehend the true outcome of what these measurements and observations really mean:
“The thing that grabs me the most is how something so diaphanous, so brainless — so incredibly, unbelievably simple — can cause so much devastation and so much death and so much harm.”
The author fails to understand that it is not the jellyfish who is at fault. It is the humans who intruded upon their environment, and who caused the warming acidic oceans in the first place. In an unbalanced environment, jellyfish populations are growing enormously. Ocean warming and acidification is caused by human emissions, there is virtually NO possibility of reversing this by human endeavor.
“This booklet, based on the National Research Council report Climate Stabilization Targets: Emissions, Concentrations, and Impacts Over Decades to Millennia (2011) outlines the scientific information that makes it clear that emission reductions today matter in determining impacts that will be experienced over the next few decades and into the coming centuries and millennia.” – Download the pdf report here (recommended).
“CO2 is not like that… It lasts in the atmosphere for hundreds to thousands of years. It doesn’t go away when you stop emitting it. Whatever temperature we hit when we finally stop emitting CO2 will be the temperature we are stuck with for the next 1000+ years.”
“I know they’ve moved the goal posts recently on this but isn’t there still a 15-20 year lag time between the time the CO2 enters the atmosphere and the resultant increase in average temperature?”
“Extra CO2 reduces heat loss to space immediately. Most of the extra retained heat goes straight into the oceans. Since 1.3 billion cubic kilometers of seawater is a massive heat sink, it takes a couple of decades for the increase to appear in the surface temperature record. This is why there are so many gloomy faces among students of climate change, amateur or professional. Most of the effects we are seeing now are due to 1990s CO2 emissions. The effects of the 21st century emissions are barely starting.”
“In addition, once the heat builds through the atmosphere as the oceans respond, you add a number of albedo, water vapor, and natural feedbacks that produce longer-term warming. The full lag period is probably around 500 years.”
Pointed out here many times before, we haven’t even begun to experience the full-force of our climate contribution emissions, nor do we begin to truly appreciate how significant the effects will be once we take in all the other positive feedbacks now occurring. Not mentioned was permafrost melt, CO₂ emissions from tropical forests (recently detected as carbon emitters), the new study on soil emissions (55 billion tons of CO₂) and so forth.
Still not realized by the ‘informed’ is what this all means. It is unstoppable now. Temperatures will soon exceed human survival and beyond.
“It’s hard not to be fatalistic about this, but I’m always grateful for everyone who’s still pushing to fight it. I especially worry about how my kids are going to cope, and I often think about some form of survivalism. But I think you’re right about that too RS, that we need to fight to keep as much of civilization as we can for our best chance.
A good example of the disconnect and refusal to accept the facts of what is now known. The insistence that civilization must be preserved at all costs while continuing to ignore the contributions to global warming by civilization. Global warming didn’t just “happen”, it has a cause. The cause is civilization. It will make virtually no difference at all to switch to “renewables” which simply hide their energy consumption and contribution to greenhouse gas emissions in their falsely claimed “green energy” output (which in turn, powers yet more civilization). There is also no mention of Jevons Paradox, where any efficiencies allegedly gained are swiftly consumed with more growth and expansion.
This is always the “more” demands, as it always is. There is never any comprehension or discussion of less. More is certainly our destruction. It is the very dish that gives us such heartburn now.
Saving civilization and all that goes with it is going to be a gigantic mistake (as it already is). It would seem like the right thing to do, but it’s the wrong path, again. Even if, for a moment, we supposed that it were possible, the outcome would be the same as it is now. Incessant growth, consumption and destruction of planetary resources leading to the collapse of the biosphere.
There simply is no way to define this civilization as compatible with habitat. It is exactly the opposite. There are also the Wasters, who will always insist on consuming and taking more then is needed.
I just picked up the book, “Against His-story. Against Leviathan” by Fredy Perlman. I’m only in a few pages, but like Thomas Ligotti’s book “The Conspiracy against the Human Race: A Contrivance of Horror” it is already evident that this will be a fascinating read, exposing the folly of man and his many ambitions and his easy self-delusions.
Perlman refers to “10,000 generations” of human experience wiped out by “time and motion engineers” in the opening pages, who having triumphed through bloodshed and destruction, eradicated the entire human history almost completely from memory, replacing it with the “cannibalization” of existence, enslaving everything. That’s a good description of civilization, a damned poor substitute for what could have been a survivable habitat for millions of years more.
But no longer. Once you grasp what these rising temperatures means, the staggering number of positive feed backs, and the sheer folly and hubris that we continue to embrace, you will realize that we are now all looking at the very end of human history on this planet.
Every single day I read commentary and articles that fail to comprehend their own words. Generally always written with an implication of success because it is simply assumed to be within our power, the vast, vast majority of authors and commentators continue to espouse the false belief that preservation and salvation of the status quo, “this set of living arrangements” must be preserved at all costs. I guess that means we should ensure that the cannibalization of existence also continues, along with the horror and slavery this really inflicts.
I’ve never believed that this is the answer and it is becoming more and more apparent every day that I’m right. Comprehension truly begins when you stop defending the indefensible.
