Where Is The “Climate Emergency”?

[toobfreak]

They say more relevant things to indicate that.

I already did. Guess you don't read.

and that is a DC application of capacitors, not AC.

That is because by themselves, caps cannot act as frequency altering agents unless combined with other devices to form tank circuits, etc.

Good point in that we can be pretty sure of Arctic ice during the cold part of the ice age cycle, but the warmest peak may have been about 10,000 years go, and it is hard to say if the Northwest Passage opened then or not.

But we know for certain the Northwest Passage has not been open since 1926.

{...
On May 9, 1926 Commander Richard Byrd announced that he had been the first to fly over the North Pole in his Fokker tri-motor airplane, the Josephine Ford. Byrd submitted his navigational records to the U.S. Navy and a committee of the National Geographic Society, who verified his claim.

The ice is so movable, the only reason the NW passage doesn't open is cant be shoved out by winds/currents. It's really a poor marker of Arctic ice,

 

[alang1216]

no, the point is you can't connect any dots and are purely acting on someone's wet dream.

One of is dreaming. I stood where a glacier used to be. That was real.

 

[alang1216]

It won't matter till your great, great, great, great, great, great, great grandkids come along. Do you honestly think that technology won't be developed to handle whatever issues come up?

That is based on what? My grandchildren will likely see the the next century, plenty of time for things to go badly wrong.

But the point is to include things relevant to the climate discussion,, and climate for at least the last million years, has been oscillating with a frequency of 110,000 years. So then there have to be positive and negative feedback aspects, similar to an AC circuit.
The sun is like a DC power source, and the greenhouse gases create a drain that ensures a net positive retention of energy.
But something then causes a 110,000 year long oscillation. I think it is the cycle of plants first increasing in abundance, then absorbing carbon until they reduce the global temperature to the point they die, and then the carbon is returned to the atmosphere where it again returns the planet to a warm state.
So these aspects can be oscillator circuit analogs.

But we do not want a temperature marker to be moved.
It polar ice could be moved by winds/currents, that would ruin it as a temperature indicator.
The point is the temperature of the ice at the North Pole was never as warm as it is now.
And we know people were looking for and failed to find a Northwest Passage for hundreds of years, even in summer.
(there is a convoluted southern coastal zigzag along Canada that someone did, but it took 3 years and relied on warm rivers to open holes in the ice)

Your comment that tiny changes in greenhouse gas retention leading to Venus like conditions is ridiculous. Who told you that?

It is obvious first of all, since the temp of Venus is NOT primarily due to it being closer to the sun.

But obviously global warming has positive feedback mechanisms that have to lead to a race condition, if allowed.
In particular, the hotter the planet gets, the more moisture evaporates into the atmosphere, and that then greatly increases the heat retention.

There is no way to stop the Earth from becoming the temperature of molten lead if we get to the point the temperature gets high enough to start enough water vapor evaporating.

Will Runaway Water Warm the World?

As the Earth heats up more water will make its way into the atmosphere, trapping even heat near the surface. To predict how much temperatures could rise in the future, scientists are working to understand how much water could enter the atmosphere and how that might contribute to climate change.

Will Runaway Water Warm the World?​

Across the globe, temperatures are slowly creeping up. According to the U.S. National Climatic Data Center, the global average surface temperature has gone up 0.4 degrees Celsius (plus or minus 0.1 degree) in the past 25 years alone. While the extra heat may not have you sweating yet, larger increases are predicted, and that has some people tugging at their collars. The Intergovernmental Panel on Climate Change, a policy advisory group made up of members of the World Meteorological Organization and the United Nations Environment Programme, estimates that the average global surface temperature could climb anywhere from 1.4 to 5.8 degrees Celsius by the year 2100.

Part of the reason the predicted temperature range is so great is that scientists don’t entirely understand whether the atmosphere will become more humid as it warms, and humidity is one of the primary factors that will influence how much the climate will warm over the next century. If the humidity of the atmosphere does indeed increase, it can as much as double the warming from carbon dioxide alone. Thus, an understanding of how the humidity of the atmosphere will change is of fundamental importance in predicting future climate. The problem is one that Ken Minschwaner and Andrew Dessler, researchers at NASA Goddard Space Flight Center, have worked to remedy using data from the Upper Atmosphere Research Satellite (UARS).

Minschwaner, also a Professor of Physics at the New Mexico Institute of Mining and Technology, and Dessler, also a researcher with the University of Maryland’s Earth System Science Interdisciplinary Center, formulated a simple, one-dimensional model to describe how the humidity of the atmosphere will change as the Earth heats up in response to carbon dioxide emissions from burning of fossil fuels. Surprisingly, their model predicted smaller increases in humidity in the upper atmosphere than large global climate models do, and data collected by the Microwave Limb Sounder and the Halogen Occultation Experiment on NASA’s UARS satellite support their model. Their findings imply that the Earth will warm significantly, but probably not as much as most global climate models predict. Their results appeared in the Journal of Climate on March 15, 2004.
...
Predictions of warming in the next 100 years vary by about 5 degrees Celsius, from a low of 1.4 degrees to a high of 5.6 degrees. The wide variation is due in part to uncertainty in the magnitude of the feedback between warming and increased rates of evaporation. In this graph, dark green areas represent predictions based on the averaged results of multiple climate models, while light green areas represent the predictions of single climate models.

And how could anyone possibly make any money of AGW?
There is no product to sell and no one to buy anything.

Gov research is free because the people are already on staff.

Carbon credits.

DUUUUURRRRRRRRR

 

[Rigby5]

Carbon credits.

DUUUUURRRRRRRRR

Carbon credits were never implemented.
And the idea was actually invented to help give an edge to the US, where we would be able to sell our ability to produce things more clearly.
That would not have cost us money, but made money for us.

 

[jc456]

One of is dreaming. I stood where a glacier used to be. That was real.

I live where ice glaciers use to be!

 

[jc456]

Wrong.
People traversed the North Pole before 1958.
They did it by land and plane.
The Vikings never tried to get anywhere near to the north pole.

Isn’t Greenland part of the Arctic?

On something that’s a wet dream!!

Ummmm, yeah, they have.

If you live in the USA north of Latitude 40 North, you were under a mile thick slab of ice.

 

[alang1216]

If you live in the USA north of Latitude 40 North, you were under a mile thick slab of ice.

And if you lived in Doggerland you didn't.

 

[westwall]

And if you lived in Doggerland you didn't.

And then as the ice melted it flooded Doggerland. What's your point? There is no danger of the Antarctic ice sheet melting. The ice shelves are already floating in the water so that is a non issue as well. In the 1850's it was possible to sail 300 miles further south than we can today. Amazingly enough the world changes irregardless of what tiny little us do.

And it was also done in a very small reinforced fishing boat, not a large ship. In 2016, a 1000 passenger luxury liner transited the passage with no problems.

[flacaltenn]

Wrong.
If you live in lowlands like Bangladesh, islands like Micronesia, or coasts like Alaska, then global warming has already raised ocean levels enough to force them to move.
The big disaster is not a thousand years away, but likely less than 200 years away.
Nor is there any technology capable of stopping it.
It is 5 trillion tons of carbon we add to the atmosphere every single year.
There can be no easy fix once we do that long enough.

Here's the historical tidal gauge data for Vanuatu -- Go look it up on a map, Any other places you'd like me to CHECK for you? Be specific. Be real nasty to have your hair on fire before you check the gauges.
