Surprise In Earth's Upper Atmosphere: Mode Of Energy Transfer From The Solar Wind
www.sciencedaily.com
"Its like something else is heating the atmosphere besides the sun. This discovery is like finding it got hotter when the sun went down," said Larry Lyons, UCLA professor of atmospheric and oceanic sciences and a co-author of the research, which is in press in two companion papers in the Journal of Geophysical Research.
"We all have thought for our entire careers — I learned it as a graduate student — that this energy transfer rate is primarily controlled by the direction of the interplanetary magnetic field," Lyons said. "The closer to southward-pointing the magnetic field is, the stronger the energy transfer rate is, and the stronger the magnetic field is in that direction. If it is both southward and big, the energy transfer rate is even bigger."
However, Lyons, Kim and their colleagues analyzed radar data that measure the strength of the interaction by measuring flows in the ionosphere, the part of Earth's upper atmosphere ionized by solar radiation. The results surprised them.
"Any space physicist, including me, would have said a year ago there could not be substorms when the interplanetary magnetic field was staying northward, but that's wrong," Lyons said. "Generally, it's correct, but when you have a fluctuating interplanetary magnetic field, you can have substorms going off once per hour.
"Heejeong used detailed statistical analysis to prove this phenomenon is real. Convection in the magnetosphere and ionosphere can be strongly driven by these fluctuations, independent of the direction of the interplanetary magnetic field."
Space radiation hits record high
Now, the influx of galactic cosmic rays into our solar system has reached a record high. Measurements by NASA's Advanced Composition Explorer (ACE) spacecraft indicate that cosmic rays are 19 per cent more abundant than any previous level seen since space flight began a half century ago."The space era has so far experienced a time of relatively low cosmic ray activity," says Richard Mewaldt of Caltech, who is a member of the ACE team. "We may now be returning to levels typical of past centuries."

Observational arguments in favor of such a cloud are presented, and implications of the presence of a nearby cloud are discussed, including possible changes in terrestrial climate. It is suggested that the postulated interstellar cloud should encounter the solar system at some unspecified time in the near future and might have a drastic influence on terrestrial climate in the next 10,000 years.
Ribbon at Edge of Our Solar System: Will the Sun Enter a Million-Degree Cloud of Interstellar Gas?
ScienceDaily (May 24, 2010) — Is the Sun going to enter a million-degree galactic cloud of interstellar gas soon?
Scientists from the Space Research Centre of the Polish Academy of Sciences, Los Alamos National Laboratory, Southwest Research Institute, and Boston University suggest that the ribbon of enhanced emissions of energetic neutral atoms, discovered last year by the NASA Small Explorer satellite IBEX, could be explained by a geometric effect coming up because of the approach of the Sun to the boundary between the Local Cloud of interstellar gas and another cloud of a very hot gas called the Local Bubble. If this hypothesis is correct, IBEX is catching matter from a hot neighboring interstellar cloud, which the Sun might enter in a hundred years.

I mean really, do you think that mankind has not had any impact on earth at all? I personally think that both sides are right. Earth has it cycles and right now it is on a warmer cycle and soon it will to start a cooler one, but to say that mankind is not responsible for some part is is just ridiculous.
Why is that?... Yes mankind has caused environmental problems, but that doesn't mean mankind can change the climate of this planet. There is not one iota of evidence to support the claim that CO2 causes the warming claimed by the anthropogenists, not one. If there was the main proponents of the AGW/Anthropogenic Global Warming scam wouldn't have been caught falsifying data, publishing false information which they knew was false, they wouldn't be trying to hide the truth about past Climate Changes, and they wouldn't have been caught doing other tactics to hide the truth, but they were caught, and if Mann, Jones, et al couldn't find any evidence to back their claim that CO2 causes tremendous warming, how could you?

It's amazing how dumb these people are. THey think because the government are trying to turn a profit that the entire thing is made-up. Despite the scientific objective facts proving it to be a reality beyond any question.
How can anyone not see the damage we've done, do you all live in the clouds?

Please, do tell me just one of these "facts" you speak about. Tell me one universally agreed upon and accepted fact supporting AGW?
Remember, AGW is just a theory, with no more factual evidence to support it than there is to prove aliens exist. For every graph, or paper, or article you link, someone can find an equally supported counter view.
A weaker solar cycle is accompanied by a slightly dimmer sun, which changes the average temperature on Earth.
The exact role the flow plays in the solar cycle remains a matter of debate but research "demonstrates how the inner working of the sun, and variations in the plasma flow deep within our parent star can control its magnetic and energetic output, which in turn, determines the environment in space and affects climate on Earth," Nandy says.

It's no longer a theory.
You sir have just been ingoring facts and scientific papers around the subject. You probably ignore them as "propaganda" and that is your own fault.
Think of the world as a living body. Dump a bunch of radiation and oil in it and what happens? Good things?
It's fact driven common sense.

The finding that the recent hiatus in warming is driven largely by
natural factors does not contradict the hypothesis: “most of the
observed increase in global average temperature since the mid
20th century is very likely due to the observed increase in anthropogenic
greenhouse gas concentrations (14).”

Who is "most of the scientific community"? You're not providing me with any facts here. Just a blanket statement.

PNAS Report from July 4th, 2011
Thats a very interesting hypothesis. It's very vague, as most are, but none-the-less, AGW is not an accepted, proven FACT!!
I believe the jury is still out on this one.
Ok you are right, I will give you that a lot of it is hypothesis driven on facts. I will also agree that not everything is full accepted by all scientists and also agree that the jury is not in. All we can do is assume at a global scale.
I don't know if we will ever have the technology to build a planet from data and then destroy aspects of the ecosystem to prove anything and essentially dictate items as fact.
Maybe I assume too much, but you can't keep stripping away elements of an ecosystem without it affecting things in that ecosystem.
My common sense says we affect the world and hurt it more that help it.
Am I calling for strong legislation and green taxes etc? No.
I do wish that we would maybe usher in another Manhattan type project to develop a better energy source though.
There are two groups out there. One that believes we need to change our ways to save the planet and another side that says we don't affect climate change. While both sides have a cause and possibly a motive for believing what they believe, which side says that Global Warming is a myth? What are their motives? Their motives seem to be that they want to do anything to prevent their Q4 profits from dipping.

Meanwhile we think the Solar System will enter this interstellar cloud in 100 years, it doesn't mean we are not being affected by it already, since the evidence seems to prove it is affecting us already.
Also of note is the fact that about 10 years ago scientists thought the Solar System would encounter this interstellar cloud in 50,000 years, and 2 years ago we thought it would happen in 10,000 years, and now we think it would be within 100 years. The way it is going maybe we are already inside it.
