"Based on current understanding, only the collapse of marine-based sectors of the Antarctic ice sheet, if initiated, could cause global mean sea level to rise substantially above the likely range during the 21st century," it read. "However, there is medium confidence that this additional contribution would not exceed several tenths of a meter of sea level rise during the 21st century."

Note the word "additional"!

oh, dear... Sketch, you are certainly "sketchy" with your math...

Hmm. I thought 3.2mm was about 1/10th of an inch.

hmm, I thought there were 25.4 mm per inch so 3.2mm would be?

3.2 (mm)/25.4 (mm/in) = 0.13 in

you're low by 30%

I'm sure there are remedial math classes at your local junior college that have openings for "adults"

maybe you should consider taking a few...

Really?

I made a mistake. I admitted it.

Edit: It's closer to 1/8th of an inch. Sorry about the mistake.

Now, you're trying to give me flack over it.

How desperate.

Sad.

Except, you made your mistake in a post where you were giving someone else flak about their math. Were you being desperate, or just clownish?

That global sea ice graph I posted yesterday brought out a whole bunch of stupid, most graphs aren't so magic. This one won't be but it seems interesting in its own right, something drawn for a talk I'm supposed to give later this winter.

Using simple indicators for New Hampshire winter temperature, divided into North and South regions, it tracks changes from 1895-96 to 2011-2012 (the most recent complete USHCN data). Smoothed curves show both regions following the signature cold-warming-pause-warming pattern of 20th century global temperatures. But in the case of New Hampshire winters the warming has been greater than global, with consequences for the state's forest ecosystems, winter sports and much more.



The warming averages about 0.2 degrees F per decade in the North, and 0.3 degrees F per decade in the South. Works out to about 2.5 F in the North and 4 F in the South, over the course of these data. The deer ticks and the ski areas have noticed.

If you've got beetles, let your timber industry cull them, if you have late arriving snow use up some of your precious water resource to make snow, if your skiers are depressed have them move elsewhere.

Maybe I was wrong, even that NH winter graphic brings out the stupid. Rick, you reliably have no idea what you're talking about, yet proclaim with such D-K self-assurance.

Regarding my statement about "man caused some warming", my point was the criteria "man caused warming" is completely open ended. The level of man's contribution to global warming is undefined. The criteria allows for any amount of contribution by anthropogenic forcings.

I look at all criteria and believe that you statement would fit into level 6 or 7.


You claim the criteria sets the minimum for anthropogenic contribution at 50 per cent. Where, in the criteria for levels 2 and 3, is that criteria stated?What's your basis for that claim?

My bases for that claim is that level 1 and 7 use that criteria and that level 2,3,5 and 6 is considered as the same criteria but with uncertainties attached because the quantification is not included in the abstract.

You seems to suggest that statements like
"man caused some warming"
"man caused a minimal amount of warming"
"man caused a small amount of the warming"

Would be considered at level 2 while

"man caused 40% of the warming" obviously should be put into level 7.

From the article
"Explicitly states humans are causing global warming or refers to anthropogenic global warming/climate change as a known fact"

I also interpret these statements as strong statements that is only used when the author thinks that most of the global warming is caused by humans. The theory of AGW is not that humans have caused a very small part of the warming.

These warmist tards got nothing. Winter Spring Summer Fall still
happening normally and that's really pissed them off.
They insanely thought that their warmist IPCC fantasy papers could
magically cause the climate to change.

I see. Since level 7 explicitly states that humans are causing less than half of global warming, any paper that implies humans are causing warming (without clarifying how much warming or minimizing the human impact) should be interpreted as saying humans are causing at least 50% of the warming.

Is that about right?.

Let's try this again:

Level 7 explicitly states that humans are causing less than half of global warming.

Level 6 explicitly minimizes or rejects that humans are causing global warming

Level 5 implies humans have had a minimal impact on global warming without saying so explicitly

Levels 2,3,5 & 6 have no criteria about the degree humans have contributed to recent warming. Instead, they seem to group papers by whether they support or oppose anthropogenic factors. Yet, you seem to think levels 2 & 3 only contain papers supporting "most of the warming".

Since you have been relying on the abstract and not the actual paper, I'm posting the Levels of endorsement, Descriptions and Examples from the paper.

It's obvious your 50% criteria doesn't hold water, based on the paper's definitions.

If you still think your right, based on the paper's definitions, please explain why.

Here are the Definitions of each level of endorsement of AGW.

(1) Explicit endorsement with quantification
Explicitly states that humans are the primary cause of recent global warming
‘The global warming during the 20th century is caused mainly by increasing greenhouse gas concentration especially since the late 1980s’

(2) Explicit endorsement without quantification
Explicitly states humans are causing global warming or refers to anthropogenic global warming/climate change as a known fact
‘Emissions of a broad range of greenhouse gasesof varying lifetimes contribute to global climate change’

(3) Implicit endorsement
Implies humans are causing global warming. E.g., research assumes greenhouse gas emissions cause warming without explicitly stating humans are the cause
‘. . . carbon sequestration in soil is important for
mitigating global climate change’

(4a) No position Does not address or mention the cause of global warming

(4b) Uncertain Expresses position that human’s role on recent global warming is uncertain/undefined
‘While the extent of human-induced global warming is inconclusive.. .

(5) Implicit rejection
Implies humans have had a minimal impact on global warming without saying so explicitly
E.g., proposing a natural mechanism is the main cause of global warming
‘. . . anywhere from a major portion to all of the warming of the 20th century could plausibly result from natural causes according to these results’

(6) Explicit rejection without quantification
Explicitly minimizes or rejects that humans are causing global warming
‘. . . the global temperature record provides little support for the catastrophic view of the greenhouse effect’

(7) Explicit rejection with quantification
Explicitly states that humans are causing less than half of global warming
‘The human contribution to the CO2 content in the atmosphere and the increase in temperature is negligible in comparison with other sources of
carbon dioxide emission’

Amazed that some think CYCLES arent part of this world. EVERYTHING cycles. Fish, birds, lakes and weather. Climate has cycled up and down since time began. Lakes go from clear to green and back to clear. ALL by themselves.

But somehow AGW types think this is disturbing news. Granted man has added some pollutants to the mix. BUt what would CO2 and temps be doing right now if man had never industrialized himself? I would imagine it would be close to the same. Natural occurrence was to blame for every spike in history up to the industrial revolution. So now we just assume man is to blame for all of it now eh..

Hey Nature - Why did you delete your post about the sea level rising 10 feet?




























Don't sweat it. I saved it for everyone to enjoy.

I had not had my coffee and I was off by an order of magnitude. Chuff already posted it.

I deleted it because my math sucked. You could delete a bunch of posts for the same reason.

Yes, the rock record is filled with cycles of high and low sea level stands, and the only way to do that globally is by accumulating and melting sea ice.

In sequence stratigraphy, these fit the milankovitch cycles. However right now we aren't in a warming part of those cycles.

Petroleum geologists work these cycles like crazy. They control the distribution of reservoir rocks for oil and gas.

There is a good wiki page on it, but for our use, these words are important:

These alternating high and low sea level stands repeat at several time scales. The smallest of these cycles is approximately 20,000 years, and corresponds to the rate of precession of the Earth's rotational axis (see Milankovitch cycles) and are commonly referred to as '5th order' cycles. The next larger cycle ('4th order') is about 40,000 years and approximately matches the rate at which the Earth's inclination to the Sun varies (again explained by Milankovitch). The next larger cycle ('3rd order') is about 110,000 years and corresponds to the rate at which the Earth's orbit oscillates from elliptical to circular. Lower order cycles are recognized, which seem to result from plate tectonic events like the opening of new ocean basins by splitting continental masses.

Hundreds of similar glacial cycles have occurred throughout the Earth's history. The earth scientists who study the positions of coastal sediment deposits through time ("sequence stratigraphers") have noted dozens of similar basinward shifts of shorelines associated with a later recovery. The largest of these sedimentary cycles can in some cases be correlated around the world with great confidence.

You should use global warming instead of warming in what you write. If that the case I would think so.
