My Polar bear says it's ****.

 

Maybe we could use their pelt to make fur coats to away to give away to war veterans for free. Not those other OAPs who aren't veterans, they can pay for them.

PS not those Iraq war veterans either, they dont count.

 

Recycling Polar bears that are surplus to requirements............

Energy storage, how do you suggest that this system is done in a way that the energy stored is more than the energy used to produce the storage over its useful life?

 

I think I mentioned Bikini Atoll a few weeks ago, who are also experiencing problems. I may have mentioned Kiribati before but at least a couple of
years back now. Another set of Islands that are disappearing are the Carteret Islands near Papua New Guinea

 

It's all a big scam engineered by the wellie manufactures and timpsons.

 

Get ready for a whole raft of cut and paste rainfall maps

 

I'm concerned bout Bikini Bottom, what will happen to SpongeBob?

 

He's going to be bleached mate.

 

I am still trying to learn more about this so I re-read your post, To back up your claim of temperature stability you introduced a new reference point of temperature changing 35 degrees in a day, can you please explain this a little more and how it relates to the data in figure 16 ie Northern Hemisphere annual mean land temperature.

Thanks in advance for your help.

 

Fair enough, Bikini is part of the Marshall Islands and also sees plenty of storms and occasionally severe hurricanes.
As for Islands, they are either emerging or sinking all over the world, no land mass is static it all moves and the pacific is particularly volatile.
How can we say the seas are rising when there are records from all over the world that show sea level dropping, there has been no sea level rise where I am for decades it's dropped steadily.


Another thing that flies in the face of this nonsense is we are at all time highest global ice coverage in recorded history. The arctic\greenland is currently recording ice gain that surpasses anything we have on record. This area is important because it is the most responsive to temperature.

Do you not see what is going on? You are beaten to death with news about Greenland in July or August where we didn't even hit record melt levels. Yet where is the reporting when there is record growth?

That is a fair question and the answer is simple. Propaganda.
Loud shouting in summer and silence in winter.. hardly science is it

The Guardian and NYTimes are STILL telling readers it is melting

 

How hard is it to conceive the notion that a planet with most of it's surface water, puts more water vapour into the air as it warms up via natural cycles.

CO2 has nothing to do with it ffs. Water vapour is impossible to model so they ignore it, that is they ignore 95% of greenhouse gas, and ignore natural CO2, which is 95%+ of all CO2.

Then they "Assume" that extra CO2 and temperature is man made That is an assumption, there is not one paper that shows empirically where atmospheric CO2 has come from. It's a guess, nothing more.

 

Any chance you could expand a bit or answer my questions re those natural cycles?

 

But sea ice isn't the prime issue is it?

It's the melting on land glaziers that are still receding that's the prime concern. Sea ice doesn't alter the total volume of the oceans, melting land based glacial ice does.

You're again merely portraying half the argument here.

 

I thought Bikini was part of the Carolines?

 

Astronomers spot most distant object in the solar system, could point to other rogue planets

NATIONAL HARBOR, MARYLAND—Astronomers have found the most distant object ever in our solar system, three times farther away than Pluto. The dwarf planet, which has been designated V774104, is between 500 and 1000 kilometers across. It will take another year before scientists pin down its orbit, but it could end up joining an emerging class of extreme solar system objects whose strange orbits point to the hypothetical influence of rogue planets or nearby stars.

“We can’t explain these objects’ orbits from what we know about the solar system,” says Scott Sheppard, an astronomer at the Carnegie Institution for Science in Washington, D.C., who announced the discovery here today at a meeting of the American Astronomical Society. V774104 currently sits 15.4 billion kilometers from the sun, or 103 astronomical units (AU) away. One AU is the distance between Earth and the sun.

The dwarf planet could eventually join one of two clubs. If its orbit one day takes it closer to our sun, it would become part of a more common population of icy worlds whose orbits can be explained by gravitational interactions with Neptune. But if its orbit never brings it close to the sun, it could join a rare club with two other worlds, Sedna and 2012 VP113.

These two dwarf planets never come within 50 AU of the sun, and their orbits swing as far out as 1000 AU. Sheppard calls them “inner Oort cloud objects” to distinguish them from icy Kuiper Belt objects, which reside between 30 and 50 AU. The Oort cloud is a hypothetical, thinly populated sphere of icy bodies, thousands of AU away, that marks the edge of the solar system and the end of the sun’s gravitational influence.

Subaru Telescope by Scott Sheppard, Chad Trujillo, and David Tholen





A moving blip in a forest of stars, V774104 was spotted last month by the Subaru telescope in Hawaii.



What makes the inner Oort cloud objects interesting is that their eccentric orbits cannot be explained by the known structure of the solar system: Something else had to perturb their orbits. Possible explanations include an unseen giant planet that still orbits in the deep or one that was ejected from the solar system, disturbing inner Oort cloud objects on its way out. Other theories suggest that gravitational forces, acting on the solar system when the protosun was surrounded by other stellar nurseries, could have provided the necessary nudges.

Mike Brown, a planetary astronomer at the California Institute of Technology in Pasadena unaffiliated with the discovery, says that this is the allure of these extreme objects. “They carry the signature of whatever else happened,” he says. But until Sheppard pins down its orbit, V774104 may be interesting—or not, Brown says. “There’s no way to know what it means.” On the other hand, Brown acknowledges that he will have to give up the claim to having discovered the most distant solar system object, which came in 2005 when he found the dwarf planet Eris at a distance of 97 AU from the sun. “I have held the record for 10 years,” he says, jokingly. “I have to relinquish it. So I’m sad.”

The discovery reflects a number of extreme solar system surveys that are using telescopes with both big mirrors and large fields of view—necessary to find faint solar system objects that could be almost anywhere on the sky. Sheppard made his discovery with colleagues using Japan’s 8-meter Subaru Telescope in Hawaii. Unlike many searches for distant objects, which peer into the solar system's plane, Sheppard is training Subaru on swaths of the sky an average of 15° away from the ecliptic, the better to find other weird objects.

 

In 1915, the universe was small and static. Space was smooth. Gravity pulled things to the ground. At least that’s the way it was in the minds of all but one exceptional physicist — Albert Einstein.

After years of pondering the interplay of space, time, matter and gravity, Einstein produced, in a single month, an utter transformation of science’s conception of the cosmos: the general theory of relativity.

His special theory of relativity, introduced a decade earlier, had united space with time, and matter with energy. Soon thereafter he saw that a generalized version of relativity would merge spacetime and matter-energy to produce gravity. Rather than “pulling” each other together, masses warped the fabric of spacetime — and then moved through spacetime along the curves that such warping produced.

Einstein’s space-bending theory was mind-bending. It not only succeeded in explaining gravitational mysteries where Newton’s law failed, but it also predicted amazing unsuspected natural phenomena, from black holes to the expansion of the universe itself. No longer small and static, Einstein’s universe is expansive and dynamic, home to a zoo of bizarre astrophysical beasts inexplicable without general relativity’s help.

Today astrophysicists manipulate those phenomena to probe the heavens, while other physicists seek ways to reconcile general relativity with the past century’s other revolutionary theory, quantum mechanics. It may now be that general relativity’s confluence with quantum mechanics is on the verge of producing a new theory, glimpsing more deeply into the essence of existence than even Einstein was able to see. But it wouldn’t have been possible without him.

“Even if some modified version of general relativity must be adopted ultimately to accommodate new observations,” writes physicist Clifford Will, Einstein’s theory “will very likely still be its foundation.”

 

I was only looking at similar last week, there are about 500 large objects in our solar system, I was surprised when I read it.

Funnily though when you ask most people what Ceres is, they have no clue It's only a planet like.

 

I certainly don't agree with clifford there. In 100 years Einstein will be buried apart from a few equations. No doubt someone clueless on this is about to tell me I am wrong

this is what it looks like, clima tards cannot figure out what happens when a storm hits this area.. Look at it it's obvious what happens. No wonder it is being washed away.
