Crazy weather is turning out to be the most visible sign of global warming.
Expect more of it, and crazier.

I used to live in Tahoe, but it's been a few years since I was a snowboarder. That picture brings back a couple of the best days of my life clearly into mind.

I hesitate to assign our dry winter to global warming without doing more research. Despite our reputation for beautiful weather, northern California and the Sierra Nevada has always been plagued by droughts and floods... which is another reason to worry about climate weirdness... if they get even more weird, we're really going to have some difficulty out here.

You're right in that any single weather event can't be ascribed to global warming.
But a run of weird weather is a different matter. You might like - or like to worry about :tongue: - this: http://www.accuweather.com/en/weather-b ... ch/8834541 and this - http://www.reuters.com/article/2012/07/ ...

The weather was difficult during Ice Ages as well. This is Samsara.

I am sure that bad weather events occurred in the past as well.

For example, when it comes to Earthquakes:

If CO2 is an effect (which lags) temperature changes, and it was not merely an initial event, then cause-effect relationship doesn't change.
Buckwheat wrote: In the past, warming intiated by changes in Earth's orbiatal characteristics triggered a chain of events. This time, human activity (extracting hydrocarbons from deep within the earth and releasing CO2 into the atmosphere) is triggering a chain of events.
I bolded what I believe is important in your quote .

Even before humans, the Earth was naturally releasing CO2. In your own quote you use words such as "extracting" and "releasing" implying that we do not produce but release and emit already existing natural stores.
Buckwheat wrote: The definition of "feedback" is that CO2 is both a cause and an effect of global warming
This finding, in the words of Caillon et al., "confirms that CO2 is not the forcing that initially drives the climatic system during a deglaciation." Nevertheless, they and many others continue to hold to the view that the subsequent increase in atmospheric CO2 -- which is believed to be due to warming-induced CO2 outgassing from the world's oceans -- serves to amplify the warming that is caused by whatever prompts the temperature to rise in the first place. This belief, however, is founded on unproven assumptions about the strength of CO2-induced warming and is applied without any regard for biologically-induced negative climate feedbacks that may occur in response to atmospheric CO2 enrichment. Also, there is no way to objectively determine the strength of the proposed amplification from the ice core data.

click on the image to show all of it.
Here is graph of temperature for the past 12,000 years. (right is present, left is past).
Please note, the average temperature is going down and that is with all alleged human induced warming... Nothing strange except that with all the alleged human made warming due to CO2 emissions, there is nothing abnormal in temperature which is falling btw.

Here is graph of temperature for the past 350,000 years to put the above into more proper context.

Please note:
1912 to 1961: the temperature increase is 0.52C, while the CO2 increase was 18ppm.
1962 to 2011: the temperature increase is 0.41C, while the CO2 increase was 74ppm.
If CO2 amplifies global warming, then shouldn't it mean that more co2 = warmer, less co2=colder?
This graph shows that the role of CO2 is over-exaggerated



I am perfectly willing to accept AGW if I see sufficient reasons. So far, and as charts above show, I have no reason believing in humans significantly, if any, contributing to warming.

That Economist article is strange. It has the whiff of being written by an idiot who is at most ambivalent about AGW. Yet the actual content is not greatly in error. It is its composition, its emphasis that sucks. And this it does so badly as to make it a grossly misleading account.

I noticed Ad Hominem again. I've bolded it. I don't think that AGW proponents make themselves more believable by calling others "idiot" or "denialist" (nobody denies climate change and denialist sounds like a holocaust denial) or by saying "that sucks". Тоо me it even looks like desperation.

"Denial" is a common term in pop-psychology (and possibly real psychology). Our use of it has nothing to do with the holocaust, and everything with seeing a group of people in denial about the reality of something that is clearly evident to the vast majority of climate scientists.

This is not ad hominem, which is by definition irrelevant to the point being discussed. Kim was showing that the article, like so many written by denialists, cherry-picks the real data from a scientific report, but continues to draw their own conclusions, based not on science, but on their personal journalistic agenda. Therefore, the argument in the article is suspect. The conclusions inferred from the data have not been subjected to the peer-review process, they are simply the opinion of a journalist and the editor. That is very relevant.

Since when calling someone an "idiot" rather than providing better point by point refutation of a view is not ad hominem?
An ad hominem (Latin for "to the man" or "to the person"[1]), short for argumentum ad hominem, is an argument made personally against an opponent instead of against their argument. link
What do you have to say about more recent charts that I've provided in my post?

Even with all the human CO2 emission, the overall temperature can go down and in the 1970's there was a global cooling scare, yet human CO2 emissions continued to rise. If CO2 amplified global warming, as you kept saying, why as CO2 emissions rise, temperature doesn't always rise?


How much long term correlation is there between CO2 levels on Earth and temperature?

CO2 rose from 4,400 to 7,000 yet average global temperature remained steady at ~23C. (1st half of Cambrian)
CO2 fell from 7,000ppm to ~4,400 yet average global temperature remained steady at ~23C (2nd half of Cambrian)
CO2 fell from ~4,400 to 3,000 yet average global temperature was flat at ~23C (Silurian)
CO2 rose and fell between 3,000 and 4,000 yet global temperature remained at ~23C. (end of Silurian and first half of Devonian).
CO2 fell from 2,000 to ~900, yet average global temperature increased and then stayed at ~21C (Cretaceous)
*CO2 numbers are in ppm

Buckwheat wrote:like so many written by denialists, cherry-picks the real data from a scientific report, but continues to draw their own conclusions,
Cherry picking the data is when someone claims that today's temperature rise is catastrophic and draw hockey-stick graphs where you compare the current temperature to one of the coldest periods it has ever been in past 600 million years, rather than to the USUAL temperatures.

Since we are in interglacial, of course the temperature is going to sometimes bounce off a little bit from the lows. This has nothing to do with human activity. If you check my graphs above, even the rate of change today is not that big as it was before in past 12,000 years.

In 1970s there was global cooling scare, yet CO2 levels were increasing. Then came global warming concern. Then as temperatures weren't always rising, the AGW proponents made a smart move at renaming to "climate change", as if climate doesn't change. Now, no matter how climate changes (becomes hotter or colder) it can conveniently be blamed on humans.

Nobody denies that climate changes.
Kool Aide is what "The Sheeple" drink when they cannot understand factors , and/or think past the science of climatology. Suggest that all the sciences must be consulted before deciding the exact cause of global warming.

And be reminded: No matter which way the temperature fluctuates with respect to anthropometrically generated CO2, the fact still remains that "correlation does not equal cause." ... no matter what your local climatologist believes. There is a reason why they cannot predict the weather accurately beyond four days.
Cause and correlation are terms that are often confused or used incorrectly. A correlation means a relationship between two or more things: when one increases, the other increases, or when one increases, the other decreases. A cause is something that results in an effect; for example, heating water to a certain temperature will make it boil. The crucial point is that a correlation between two things does not necessarily mean that one causes the other. If there is a relationship between two phenomena, A and B, it could be that A causes B, or it could be that B is responsible for A; other possibilities are that some other factor is the reason for both A and B, or that they have independent causes that just happen to run in parallel.

Correlation

Researchers trying to find reasons for various things will often use statistical methods to establish correlations: this may be the first step toward establishing the cause. Scientists and statisticians can use a formula to determine the strength of a relationship between two phenomena. This gives a figure, known as the square of the correlation coefficient, or R2, which always lies between 0 and 1, with a value closer to 1 indicating a stronger correlation.

Right, correlation is not causation.

Also, it seems that no matter what the weather does (rises or falls), some can still keep blaming human's CO2 emissions for it - no matter what it does.
Even if there are less than normal amount of extreme events, humans could still be blamed...

IPCC have said that: "The future level of global warming is uncertain,"

And yet, some find cataclysmic predictions and how warm it will be in the next 10-100 years credible... :jawdrop:

Yes. And you will continue to miss it until you start drinking the global warming KoolAid . I think it has something in it like peyote, which makes you see what the "climatologists" want you to see.

In the mean time, only buy property in the highlands :coffee:
