Wel

Well you have posted enough conspiracy fuelled science fiction to keep you busy

 

Why would anyone read the posts of a ****wit like you when there are so many conspiracy websites to copy/paste

 

"Most of my most knowledgeable scientist friends don't believe that global warming exists. I have still not seen any proof that the planet is increasing in temperature, or that we have a hand in determining such changes. I do think the concept has led to some good changes. such as an increased awareness of how wasteful we are." - Brian May.

Queen guitarist says it so I "believe"


Though he does have a PhD in Astrophysics as well.

Before some loon says "it's not proof" or something as stupid..he's right in that there is no proof of it being real. Not one shred.

Brian May and his friends are "deniers" and "carbon shills"

Not denied, the question is whether it is legitimate.

If I cool the past 8 degrees will Helsinki be like Kingston Jamaica? Cooling the past warms the planet right?

This so confusing, I thought actual warming warmed the planet..
The 2001 version was a re write of history too, on the fraud goes

 

I have a 50m swimming badge from 1981, so it makes me just as qualified as Brian May......

But I don't wear clogs so that kinda works against me

 

Brian May is a sceptic, and he has every right to be. Note that he's not calling those who disagree with him as being some quasi-religious cult intent on taking over the world.

 

Correct, healthy scepticism has been key in mankind's 'progress', however that is is million miles away from sisu's pathological need to boost his own fragile ego.

 

Climate change SHOCK: Crumbling icebergs are actually SLOWING global warming
http://www.express.co.uk/news/scien...-icebergs-are-actually-SLOWING-global-warming

Melted ice water is food for photoplankton, a gobbler of CO2 and creator of oxygen.

So that would mean the glaciation and melt cycle is essential for the heath of the planet surely, because Photoplankton create most of our oxygen,






Oh and this, Berkeley study with new techniques find current climate anomalies have been around before, caused by increasing glaciation.

This is a map of the predominant weather patterns in mid-latitude North American from 70,000 to 55,000 years ago. The large ice sheet covering the northeastern portion of the continent caused a strong high pressure system to persist above it, which drew Gulf of Mexico-sourced precipitation (red arrows) into the mid-continent and Wyoming (white star). The result was rainy summers during this time, and possibly drier winters.

Scientists have found a new way to tease out signals about Earth’s climatic past from soil deposits on gravel and pebbles, adding an unprecedented level of detail to the existing paleoclimate record and revealing a time in North America’s past when summers were wetter than normal.

A research team led by soil scientists at the University of California, Berkeley obtained data about precipitation and temperature in North America spanning the past 120,000 years, which covers glacial and interglacial periods during the Pleistocene Epoch. They did this at thousand-year resolutions — a blink of an eye in geologic terms — through a microanalysis of the carbonate deposits that formed growth rings around rocks, some measuring just 3 millimeters thick.

“The cool thing that this study reveals is that within soil — an unlikely reservoir given how ‘messy’ most people think it is — there is a mineral that accumulates steadily and creates some of the most detailed information to date on the Earth’s past climates,” said senior author Ronald Amundson, a UC Berkeley professor of environmental science, policy and management.

The study, to be published Monday, Jan. 11, in the Proceedings of the National Academy of Sciences, shows the rich potential held within soil deposits known as ****thems, which form growth rings on rocks. The samples used in the study came from Wyoming’s Wind River Basin.

Because these soil deposits are commonly found in drylands all over the world, they can provide a rich source of data for paleoclimatologists, the authors said.

“We can now begin to develop records of how local and regional climate boundaries have shifted through time and in response to worldwide warming or cooling,” said study lead author Erik Oerter, who conducted the research as part of his UC Berkeley Ph.D. dissertation.

120,000 years of history in 3 millimeters of rock

****thems are a powerful complement to existing geological records of past climate, including ice cores, lake and ocean sediments, and stalactites and stalagmites in caves. They have the advantage of being fairly ubiquitous in regions now populated by humans, unlike the polar regions where ice cores are often obtained.

Key advances in the ability to precisely analyze micro-samples of soil deposits enabled researchers to extract telltale signs of climate change.

“By using micro-analytical measurements on spots as small as 0.01 mm in diameter, we can develop time series of past climate conditions in a way that no one has done before,” said Oerter. “It is evident that the carbonate coatings formed in concentric bands around the rocks, much like the annual growth rings in a tree, except that these laminations form over timescales of several hundred years.”

The researchers used laser ablation and an ion microprobe, much like a tiny dental drill, to obtain microscopic samples for analysis. Uranium isotopes were used to date the deposits, while oxygen and carbon isotopes revealed clues about the precipitation, temperature and soil respiration at the time the mineral was formed.

For instance, warmer rain from the Gulf of Mexico will result in higher levels of oxygen 18 compared with the cold precipitation from snowstorms blowing eastward across the Rockies. The ratio of carbon 13 and carbon 12 isotopes reflect levels of soil respiration, which is a proxy for plant productivity.

Uranium isotopes were used for dating the sample, but they can also be used to calculate how much rain the soil receives, serving as a type of “paleo rain gauge,” said Oerter, who is now a postdoctoral researcher at the University of Utah.

Finding what other records couldn’t

The new data revealed that 70,000 to 55,000 years ago, in the midst of a minor ice age, the pattern of precipitation in North America shifted from one dominated by a west-to-east flow of storms from the north Pacific to a south-to-north flow from the Gulf of Mexico. The researchers attributed that to a stable, high-pressure system that parked itself over massive ice sheets that covered eastern Canada and northeastern United States, which helped bring up more air from the south.

That atmospheric circulation translated into wetter summers and drier winters in central North America, a reverse of the usual pattern in which more precipitation falls in the winter.

Models override measurements, hey presto global warming, they dont even deny that their models are useless.
40 years to model 1 year of climate with our best computers is the best we could do now if we made a model that accounted for clouds, let alone water vapour or aerosols

Do we accept the limitations? Nope, we say we have it nailed.

How much have Britons saved in total on leccy bills this winter so far.. which reduces emissions..

 

Sisu. You are such a fantastic researcher and obvious!y talented analysist, I find it hard to understand why you haven't had any of your works published especially seeing as you are so well read yourself.

Does that help? Does it ease your pain any?

 

Interesting that the melting icebergs may actually have a slowing effect on the process of global warming by in essence offsetting some of the carbon produced. However you do realise that the reason they're melting in the first place is down to global warming eh?

I thought the glaciers weren't melting at all btw?

It is thought that manmade greenhouse emissions grow by around two per cent a year, but it would be worse without the algae, according to the results published in Nature Geoscience.

 

It's still an upward curve irrespective of whether it mirrors the model exactly.

 

From the owner of Skeptical science and the fraud paper the 97%

His school, maybe some here should enroll

Here is them telling us that the medieval warming period detected in Asia Americas and Europe, didn't happen.

The only reason we cant say it was global is because of a lack of records for the tropics and Southern Hemisphere, it being all water. They equate this to "it wasn't global".

Sign up and learn propaganda and pseudo science to combat deniers like me. report for "re-education"

This is people with ideology learning an extremely skewed one sided ideological argument that they already believe without the science, and then being loosed on the internet and society to combat growing skepticism.

The Hitler Youth of Climate Alarmism

Comments on video obviously disabled, cos then someone might post some inconvenient facts..

 

Just dawned on me how delusional NASA's GISS director is.

calls himself a Jewish Atheist. FFS Judaism is a religion obviously and he doesn't believe in god. He's just an Atheist.

We trust this idiot with such important work

 

Many people consider themselves as Jews for ethnic, historical or cultural reasons, even though they may not actively practise the religion.
If pushed, I'd probably call myself christian- even though I'm not religious- because that is my background and the term espouses a set of values and principles that I roughly adhere to.
Either way, it doesn't affect his professional capability and to highlight it is just an attack on his person, not his professional credentials, and largely irrelevant.

 

Him referencing the religion he was patently brought up with and then stating he's an atheist now somehow makes him an idiot?

You're dredging in terms of trying to discredit him there ffs.

KISSIMMEE, Fla. — Our galaxy was built from the inside out. That’s the clear conclusion from an unprecedented survey of the ages of tens of thousands of the galaxy’s stars, reported January 8 at a meeting of the American Astronomical Society. “The Milky Way grew up by growing out,” Melissa Ness, an astronomer at the Max Planck Institute for Astronomy in Heidelberg, Germany, said at a news conference.

Ness and her colleagues developed a computer program that analyzed the light emitted by red giants —bright stars that started out like the sun but exhausted their hydrogen fuel — to determine the stars’ masses and ages. Although scientists were pretty sure that galaxies grow outward, this new census of the galactic interior to the outskirts will help researchers chart that development in impressive detail. “It’s a galactic archaeology project,” says Mario Pasquato, an astrophysicist at Yonsei University in Seoul, South Korea, who was not involved in the research.

Most stars don’t easily divulge their ages. Red giants are slightly more helpful because their age depends on their mass — but determining mass isn’t so easy either. Ness and her colleagues hit on a clever trick to figure out masses and ages by encompassing data from two telescopes, one in space and one on the ground. NASA’s Kepler space telescope, best known for spotting distant planets, had previously delivered accurate mass readings for about 2,000 red giants. Meanwhile, using a small telescope in New Mexico, the Sloan Digital Sky Survey precisely measured the light from those Kepler stars plus that from about 150,000 others.

The researchers trained a computer program to learn how the amount of light emitted at different wavelengths by the Kepler stars varied depending on the stars’ mass. Once the algorithm had determined that relationship, the researchers simply plugged in Sloan light measurements to determine the masses, and thus the ages, of about 70,000 galactic red giants. The ages are accurate to within about 40 percent, which Pasquato says is admirable because of the difficulties in aging stars. As expected, the Milky Way’s oldest stars reside in the center of the galaxy, while the youngest generation lives in the distant suburbs.

This year, a new Sloan telescope in Chile will begin scanning the Southern Hemisphere skies, potentially adding many more red giants to the galactic age catalog.

There’s a trick to finding new species of miniature snails: a bucket of water.

“Microsnail” is the term for the creatures with shells measuring 5 millimeters or less, sometimes much less. A species described from China, photographed perched in the eye of a needle, ranked as the world’s smallest known land snail for five days in the fall of 2015. Then the journal ZooKeys described an even smaller species, from Borneo.


“The very tiny ones you wouldn’t see even if you put your nose on the ground,” says Menno Schilthuizen, who described the Borneo miniature with colleagues. To avoid dirty noses, the researchers drop soil and leaf litter into a bucket of water, and shells float to the top. The shells are empty, alas, but “you can easily find thousands in just a few liters of soil,” he says.

Even scooping bucket flotsam has its complications. Schilthuizen, of the Naturalis Biodiversity Center and Leiden University in the Netherlands, has been studying the snails of Borneo’s limestone hills and caves since 1997. “Sometimes people bury their dead in a cave,” he says. So they’re reluctant for anyone to enter, even for snail science. Bird nest collecting gets in the way as well. Families harvest cave swiftlet nests, a sought-after ingredient in exorbitantly priced bird’s nest soup. “These nests are very valuable and there’s a lot of poaching going on,” he says. Disputes are often settled with “a lot of shooting with homemade guns.”

Of the 48 new species of snails from Borneo that Schilthuizen and colleaguesnamed in November, the world’s smallest “was the most boring in terms of shell shape,” he says. In contrast, the region’sPlectostoma microsnails curl in fat whorls, like tubing that vents a clothes dryer. Some loop back on themselves or flare out like a tuba. “Sometimes, they tie themselves in knots,” he says. Perhaps the contortions make it more difficult for a predator to get a good grip.

Snails typically have small, or even micro, habitat ranges. At some of Borneo’s isolated limestone peaks, “you can actually stand in front of the hill and see the whole world population of one particular snail species,” he says. The sad part of microsnail hunting, Schilthuizen says, is discovering that a company blasting a hill to extract the limestone has wiped out the entire world population. RIP, Plectostoma sciaphilum.

I'd have liked to have worked on that research
