Past studies have shown that sunspot numbers correspond to warming or cooling trends. The twentieth century has featured heightened activity, indicating a warming trend.  (Source: Wikimedia Commons)

Solar activity has shown a major spike in the twentieth century, corresponding to global warming. This cyclic variation was acknowledged by a recent NASA study, which reviewed a great deal of past climate data.  (Source: Wikimedia Commons)
Report indicates solar cycle has been impacting Earth since the Industrial Revolution

Some researchers believe that the solar cycle influences global climate changes.  They attribute recent warming trends to cyclic variation.  Skeptics, though, argue that there's little hard evidence of a solar hand in recent climate changes.

Now, a new research report from a surprising source may help to lay this skepticism to rest.  A study from
NASA’s Goddard Space Flight Center in Greenbelt, Maryland looking at climate data over the past century has concluded that solar variation has made a significant impact on the Earth's climate.  The report concludes that evidence for climate changes based on solar radiation can be traced back as far as the Industrial Revolution.

Past research has shown that the sun goes through eleven year cycles.  At the cycle's peak, solar activity occurring near sunspots is particularly intense, basking the Earth in solar heat.  According to Robert Cahalan, a climatologist at the Goddard Space Flight Center, "Right now, we are in between major ice ages, in a period that has been called the Holocene."

Thomas Woods, solar scientist at the University of Colorado in Boulder concludes, "The fluctuations in the solar cycle impacts Earth's global temperature by about 0.1 degree Celsius, slightly hotter during solar maximum and cooler during solar minimum.  The sun is currently at its minimum, and the next solar maximum is expected in 2012."

According to the study, during periods of solar quiet, 1,361 watts per square meter of solar energy reaches Earth's outermost atmosphere.  Periods of more intense activity brought 1.4 watts per square meter (0.1 percent) more energy.

While the NASA study acknowledged the sun's influence on warming and cooling patterns, it then went badly off the tracks.  Ignoring its own evidence, it returned to an argument that man had replaced the sun as the cause current warming patterns.  Like many studies, this conclusion was based less on hard data and more on questionable correlations and inaccurate modeling techniques.

The inconvertible fact, here is that even NASA's own study acknowledges that solar variation has caused climate change in the past.  And even the study's members, mostly ardent supports of AGW theory, acknowledge that the sun may play a significant role in future climate changes.

I'm far more worried with the massive debt any children I have will be saddled with due to the current administrations massive spending spree than the possibility of the planet being less livable due to any impact I might have upon it.

And the fact is that we would probably arrive at commercially viable alternative energy for vehicles sooner and we WOULD have more, cleaner power if not for government interference. Instead of letting engineers tackle the problems we have politicians mandating half assed, politically motivated "solutions".

We get worse mileage due to ethanol and safety standards. We can't pursue diesel because emissions standards are so high that only recently can diesels even meet them. We can't build nuclear power plants because politicians have allowed environmental groups to hold up construction and increase costs with endless environmental impact studies. We can't drill for oil and we can't build new refineries. All we can do is build tiny cars and solar/wind power plants. Do less with less essentially.

To be fair, the lions share of that debt your kids are saddled with started early in the previous administration's tenure.

Is that a fact? Please cite credible references. Otherwise, it's just another blowhard opinion piece.

Ethanol, I agree with. If ever there was a sham market that existed, it's the current method Ethanol is produced in this country. Maybe we could do better with non-food based Ethanol. Well, that and the Hydrogen Fuel Cell nonsense. Safety standards cost weight. If you're then equating heavier vehicles with worse mileage, then why do you complain about

Tiny cars weigh less, and all other things being equal, are more efficient. Therefore, one effective way to reduce gasoline consumption is to all drive smaller cars. It's that simple. Also, technically we can do the same with less if we buy the smallest automobiles that fit our needs (not our wants).

I'd like to know your explaination for the quote above...

Some figures:

Obama as of 3/30/09 - has so far spent(*) 2.2 Trillion (*) = 1.2 t in bailouts , 800 b in TARP funds, 600 b budget allocations

The main thing people pin on Bush is the cost of the Iraq war --- I've heard people say that trillions been spent on the war....I'm not supporting the war or against it in this post -- that's not the point of this comment....but 860 billion was spent on the Iraq War up to this point in time (as of 4/09). A lot of money indeed but not HALF of what Obama has spent.

Now if you want to go back and show me that bush spent Trillions I'm sure the information is out there --- but remember.....Bush had 8 *YEARS* to be in office and spend.....Obama has passed 2 trillion in under 8 *MONTHS*.

Note: I really don't care who you blame....it doesn't change the fact that our kids will be saddled with the debt of today's bailouts.

Math error myself....makes it worse ---- Obama spent 2.6 not 2.2 trillion as of March.

Yes huge math errors. Obama spend 37 billon of the tarp money bush spent 400 billion of it. Obama programs are set to spend .9 trillion but have only spent $110 billion so far. That means bush spend over $400 in his last 6 months and Obama has spend less then $150 in only 6 months. And have not even added in the Iraq war that is project to cost tax payers 3-5 trillion.

Damn people can really pervert numbers.

If you really want to get technical, the president can't spend a dime.
However, you can point a finger square at Congress. And Congressional Democrats are to blame.

But your only comparing money spending now and not damages done. That's like complaining Guy A is spending so much on car-repairs while Guy B is the one who made all the dents and scratches. The money wasn't lost when Guy A spent it on repairs, but when Guy B drove into those trees.

Meaning, you can't blame Obama for the damage control he has to do. After all, he got dropped in the middle of it all and wasn't the cause of it. You can however question his optional spending on things like future technologies, but that isn't the bulk of his spending.

I'm guessing you just watch CNN and MSLSD and drink it all in. Obama did not HAVE to support spending trillions. He wanted to. Our country would be far better off if absolutely nothing was done and the markets were just allowed to correct themselves over time naturally. That doesn't excuse Bush's actions either but one mistake does not mean another even larger one has to be made.

Obama was a member of Congress. Obama supported Freddie Mae and Fannie Mac and the lax regulation thereof. If Obama is not the cause then neither is anyone else.

Using your analogy Guy A bought the drinks for Guy B and encouraged him to race but since Guy B was driving, Guy A holds no responsibility according to you.

Even if the numbers you use are true, do you really think that the aftermath from that war does not cost the US any money ? People always think that events in time have hard stops and new events take place with a fresh new start. Cause and effect, events fade into eachother...

Why good folks like erple who only have our best interests at heart, or course. Can someone please explain to me what exactly is a need when most of what we own or want to own is a luxury? Which, for all intents and purposes, is a want?

I agree with you on the debt thing whole heartedly. It's depressing to see the current administration keep digging holes that exceed the wildest spending of any previous adminstration. Am I far more worried about it? Let's just say I would rather play it a little safer on both environmental and economic issues. Sooner or later they both may catch up to us.

I’d be fine to trade twice his current defect if he would just sop telling my son that it is ok to be lazy and expect others to solve your problems for you.

I’m trying to teach my son that he should take responsibility for his own actions. I’m just glad he is too young to realize that his President, and other law makers, are constantly on TV telling him that it is his right as an American to feel betrayed because someone or some group is not helping him out of the messes that he has made either by his actions or his inactions.

Further, I’m glad that it is going over his head that his President is indirectly inferring that his daddy is a “bad guy” just because he prefers to work hard, save that money and use it to better his future life instead of “wanting” to give it out to every deadbeat and “interest group” that have nothing to offer society other than votes on election day.

I read an interview last year of Mr Bergström who is the CEO of GM Powertrain Sweden.

He states that the current generation of engines sees an increase of 30% consumption when switching from regular to E85. But the next generation sees only a 15% increase.

Diesel engines OTOH will become less efficient to decrease the emission of small particles.

E85 burns clean, diesel (or regular gasoline) does not.

Putting the same requirements for all types of fuel will balance out the differences in mileage.

Personally I think particle emissions is a bad thing and should be eliminated. Like so many here, I care less and less about CO2 emissions.
