Getting Cold (with thermal imaging)

oritteropo says...

Carefully

None of the endothermic reactions in this video have been suggested as methods to regulate global temperature, because even if they could be scaled up enough to make a global difference they don't address the systems which regulate the earth's temperature.

Some things which have affected global temperatures either up or down are:



Some people have proposed geoengineering to use those same mechanisms, for instance injecting sulphur dioxide into the stratosphere https://www.nature.com/articles/d41586-018-07533-4 or seeding the ocean with iron to fertilise algae https://phys.org/news/2016-03-seeding-iron-pacific-carbon-air.html although there are some concerns about both approaches.

Sir Attenborough explains global deal to protect ocean

newtboy says...

A good, even *quality idea....for 40+ years ago.

It took 100+ years to mortally wound the ocean by 1000 cuts. A bandaid on one wound is not going to turn it around, and we almost certainly aren't going to do it anyway. Countries that don't buy into the plan will simply harvest most of the fish left by those who do. This only works in small scale preserves that are guarded against poaching, often by a military.

Fish stocks are disappearing at an alarming rate, many going extinct. For those species, it's too late, and they are numerous, and they are largely the fish humans prefer. Many others are in such decline fishing for them is already off limits or severely curtailed, like commercial salmon, abalone, and crab fishing in California. Even those actions have failed to revive their populations year after year.

Diatoms, phytoplankton, and other similar biotas are at the limit of acidity and temperature they can tolerate, and they are the base of the ocean food web, feeding most fish when they are fry or larvae. The gasses in the atmosphere today will push diatoms over that precipice with a massive ocean extinction following soon afterwards, and we continue to add more greenhouse gases than we added yesterday every day.

Then there's habitat loss, coral reefs and kelp forests are both being decimated by temperature rise and acidification. Together they are food and habitat for 25%-50% of all ocean fish and shellfish.

Less over harvesting of the ocean is a good idea, but pretending it alone can save the oceans is pure fantasy. The ocean has absorbed as much as 90+% of the excess heat from global warming, causing oceanic heat waves that destroy habitats both directly and indirectly. There is NO plan that solves that problem, it's well beyond our capabilities under the best conditions with worldwide maximum efforts.

Just sayin'.

Siberian Methane Bubbles Increasing as Permafrost melts

newtboy says...

I said it before and I'll say it again....
Game over, man. Game over!

When the tundra is outgassing faster than grass can release, we're hosed.
When the ocean methane is outgassing enough that it can be seen with the naked eye in open ocean among the waves, we're toast.
That makes us soggy toast.

Grreta Thunberg's Speech to World Leaders at UN

bcglorf says...

@newtboy,
"Actually, I'm selling their audience short. When real scientists present the real data dispassionately, I think the average person gets quickly confused and tunes out."

I'd argue bored maybe more often than confused. Although if we want to say that most of the problems society faces have their root causes in human nature, I think we can agree.

"I had read the published summaries of the recent U.N. report saying we had 12 years to be carbon neutral to stay below 1.5degree rise, they were far from clear that this was only a 50% chance of achieving that minimal temperature rise"

Here is where I see healthy skepticism distinguishing itself from covering eyes, ears and yelling not listening.

Our understanding of the global climate system is NOT sufficient to make that kind of high confidence claim about specific future outcomes. As you read past the head line and into the supporting papers you find that is the truth underneath. The final summary line you are citing sits atop multiple layers of assumptions and unspecified uncertainties that culminate in a very ephemeral 50% likelyhood disclaimer. It is stating that if all of the cumulative errors and unknowns all more or less don't matter. then we have models that suggest this liklyhood of an outcome...

This however sits atop the following challenges that scientists from different fields and specialities are focusing on improving.
1.Direct measurements of the global energy imbalance and corroboration with Ocean heat content. Currently, the uncertainties in our direct measurements are greater than the actual energy imbalance caused by the CO2 we've emitted. The CERES team measuring this has this plain as day in all their results.
2.Climate models can't get global energy to balance because the unknown or poorly modeled processes in them have a greater impact on the energy imbalance than human CO2. We literally hand tune the poorly known factors to just balance out the energy correctly, regardless of whether that models the given process better or not because the greater run of the model is worthless without a decent energy imbalance. This sits atop the unknowns regarding the actual measured imbalance to hope to simulate. 100% of the modelling teams that discuss their tuning processes again all agree on this.
3. Meta-analysis like you cited usually sit atop both the above, and attempt to rely on the models to get a given 2100 temperature profile, and then make their predictions off of that.

The theme here, is cumulative error and an underlying assumption of 'all other things being equal' for all the cumulative unknowns and errors. You can NOT just come in from all of that, present the absolute worst possible case scenario you can squeeze into and then declare that as the gold standard scientific results which must dictate policy...

Edit:that's very nearly the definition of cherry picking the results you want.

Grreta Thunberg's Speech to World Leaders at UN

bcglorf says...

@newtboy,

"Ok, but don't discount the factual arguments because they are presented with passion. Ignore the emotion and focus on verifying or debunking the facts presented. Because someone on Fox presents their denial argument flatly and dispassionately doesn't make it more correct."

Obviously agreed, exactly what I was saying.

"if the facts are presented clearly and in totality, which she does better than most if not all professional scientific lecturers....sadly"

I think here you are selling scientific lecturers short, or at the least including folks I wouldn't consider scientific at all in the group.

When I think scientific lecturer, I think an actual scientific researcher giving a lecture related to their field of expertise. That even excludes scientific researchers giving lectures outside their field of expertise. I've seen how badly interdisciplinary study types can misjudge their own knowledge of a field. In the hard sciences they can get rooted out faster, but in softer sciences and humanities it's easier for them to keep finding a niche that hides their ignorance.

If you get the CERES team to give a talk on the global energy budget, they will give a lecture a thousand times more complete and accurate, than you, I or Greta ever could. They will confirm the planet is taking in more energy than is leaving. They will confirm their data is corroborated between satellite and ocean heat content measurements. They can say with authority how much energy is being gained, and can even confirm it largely corresponds to what we'd expect from the increased CO2 contributions. If you asked, they would even also admit that the uncertainties on the measured imbalance are larger than the imbalance itself.

Ask them about mating habits for European swallows and you, I or Gretta might well know better than them.

Why Shell's Marketing is so Disgusting

Nice. Hadn't thought of that. Just redraw the coastline and, boom, all the effects of ocean incursion are gone.
Sadly, that means neutering the country by erasing Florida.

If only population numbers were that easy to fix.

Back-To-School Essentials | Sandy Hook Promise

newtboy says...

At best that leaves only the rare pre 1986 automatics already in private hands, only in some states (totally illegal under any circumstances in many other states), only if you can first pass an expensive background check more stringent than the one federal agents must pass. Sounds like some serious regulation to me.

What you, me, or others consider firearms means nothing. I gave you the law as written, it includes those, they are illegal, so there are effective regulations on firearms already....that doesn't mean they're sufficient. Those words are different words, that's why they're spelled and pronounced differently. Speed limits are effective laws, but not sufficient to regulate vehicle use.

Why do so many firearms lovers fear being on a registry? I've always found that insane, like every other purchase you make isn't tracked or something. There's no purchase privacy anymore, for anything.

It doesn't take any money to ban certain firearms, certainly not a boatload, and not the ocean of cash health care costs. That's a red herring. All it takes is for representatives to vote the way their constituents want them to by 98%.
Perhaps in that sense it would take money, because in order to get them to vote as the people want, campaign finance reform is necessary, and that will cost money, but it's the best thing our country could possibly spend money on.

I support a slightly modified second amendment and universal health care. My interpretation allows for regulations, registration, universal background checks even for family transfers, bans of certain types, seizure from violent convicts and mental patients (impossible without a registry, btw), etc. Yes, I understand that's not how the constitution is written today, but the constitution is a living document. In California, we have most of that as state law already, including an outright ban on fully or selectively automatic weapons.

Btw, you suggest....Try to make people feel welcome.
I was responding in kind to your off hand assumption that, without your derisive "warning", he would be "dumb" enough to make an assumption about you. Then you go on to say making assumptions is dumb. Care to rethink? Had you been more thoughtful and less derisive in making that point I likely would have ignored the hypocrisy.

Machine guns are firearms. You can buy pre 1986 machine guns in the USA (I'm not sure what form you have to fill out). The 1986 cutoff is fairly pointless.

I don't consider bazookas, grenades, mortars, etc. firearms. To me a firearm is essentially a rifle that fires cartridges. But if the US government considers them as firearms then that is what they are for legislative purposes.

I believe there is case law regarding what scope of arms they were referring to in the 2A and the result was any common firearm. This currently includes almost all pistols and rifles, both automatic and semi-automatic (with the exception being automatic guns must have been made before 1986 - I believe this limit should be removed).

I'm very much against restricting semi-automatic rifles. There are no good reasons for restricting them. It is unconstitutional. They are not the "weapon of choice" for mass shootings, pistols are. The lethality of them in mass shootings is the same as that of pistols (someone ran an analysis just recently). This last point surprised me a little.

https://www.reddit.com/r/gunpolitics/comments/d7ypcv/no_mass_shootings_carried_out_with_semiautomatic/

I'm for background checks (i.e. for second hand sales which are the only sales left without a background check) as long as the service is cheap and no records are kept (i.e. it isn't used to create a de-facto registration database).

Public health wise, talking about firearms is a red herring. If I were to drop a bucket load of money into stuff in the USA it would be into making health care and mental health care cheap and available and reducing poverty. This would have more affect on mortality and morbidity rates then any gun legislation will. And yes, I would give fully subsidized health care to the poor.

By now you should be asking yourself what planet someone comes from where they support the 2A and free health care at the same time.

Why Shell's Marketing is so Disgusting

newtboy says...

Almost as stupid as holding the producers of the toxic product AND the misleading or outright false information about it's hazards blameless. Because they actively misled their customers, I give them the vast lions share of blame, but maybe not 100%. There's plenty to go around.

You don't have to live in poverty to abandon fossil fuels.
Not.
Even.
Close.
I bought solar 10+- years back...it paid for itself in 8. It's lifespan is 20+-. I get 12 years of free electricity for abandoning that portion, with no blackouts, no brownouts, and no rate increases.

True, the video could be better at sharing the blame, but it stayed on topic instead, that topic being major polluters greenwashing their mage. I didn't take it as assigning ALL blame to one source, just not allowing the worst offenders to shirk all responsibility for their products.


Every one of these is the likely outcome of any anthropogenic rise over 2-3C because of feedback loops that drive us to 6-12C rise. Only the wars are likely this century, but I didn't put a timeframe on those outcomes. 140 million + will be displaced by just a 3' rise, which is all but guaranteed by 2100 under the most optimistic current projections.
That wipes out mangroves and other fish nurseries, further impacting the struggling ocean food webs. All the while it accelerates as our ability to cope erodes like the shorelines....it doesn't just halt at 3' rise.
The natural food webs on land are also struggling, and are unlikely to survive ocean collapse.

Not just from deforestation, but diatoms are near a point of collapse from ocean acidification. https://diatoms.org/what-are-diatoms. That's over 1/2....and the base of the ocean food web.


Since the IPCC (again, known for overly conservative estimates) now says at current rates we could hit as much as a 6C rise by 2100, and rates of emissions are rising as fast as carbon sinks are shrinking, they're not just a possibility, they a likelihood in the near future....but granted the hydrogen sulfide clouds are far in a worst case scenario future, far from guaranteed.

@newtboy,

Walking backwards to simplify, my main point is that simply blaming ALL fossil fuel usage on the company providing the fossil fuel is stupid and misleading in the extreme. We don't see millions of people willingly abandoning fossil fuels and living in abject poverty to save the world, instead they are all very willing and eagerly buying them and this video lets all those people off the hook. This video lets everybody keep using fossil fuels, and at the same time pointing the finger at Shell and saying it's all their fault. It's an extremely detrimental piece of disinformation.

"explain what, specifically, I claimed that's not supported by the science."
-Complete collapse of the food web
-Wars over hundreds of millions or billions of refugees
-Loss of most farm land and hundreds of major cities to the sea
-Loss of well over 1/2 the producers of O2
-Eventual clouds of hydrogen sulfide from the ocean covering the land
-Runaway greenhouse cycles making the planet uninhabitable for thousands if not hundreds of thousands or even millions of years
