Global Warming, what again?
 
I just noticed we have science under technology on the front page. That makes no sense but anyway...

I don't know if this study came out while I was on vacation but it went below my radar screen. It seems that University of Ottawa geology professor Dr. Jan Veizer and astrophysicist Dr. Nir J. Shaviv have connected their work across specialties, casting doubt on the increased carbon dioxide = global warming theory.

By analyzing the fossilized remains of seashells, Veizer has been able to reconstruct the Earth's temperature record for the past half-billion years, the period during which there have been hard-shelled sea creatures. Surprisingly, this record displays a repeating cycle of temperature increases and decreases every 135 million years, a period that corresponds with no known terrestrial phenomena. Independently, Shaviv had determined galactic cosmic rays striking the Earth have been varying with about the same periodicity over an even longer time frame. Once Veizer and Shaviv made the connection, they wondered whether they were looking at a reflection of some sort of regular celestial phenomenon in the climate history of the Earth.

Indeed, it appears they were. Our solar system passes through the bright arms of the Milky Way Galaxy with approximately the same regularity as the long-term temperature changes Veizer had discovered. And because interstellar matter bunches up in the galaxy's arms, we see the birth of large, very bright, but short-lived stars that end their lives as supernovas while still inside the arms, giving off powerful bursts of galactic cosmic rays.


Read the whole article, it makes sense. The big question I have is whether or not he missuses "less" when talking about clouds. I'm thinking it should be fewer clouds/less cloud cover.

Of course, those who for political reasons want global warming to be man's fault will find the article absurd, while folks who for political reasons, like myself, don't want global warming to be man's fault will embrace it. :) I think the first thing we need to do as individuals is to identify our own motivations, after which a hardnosed look at the science, while ignoring to loaded rhetoric, is called for. Don't support anthropomorphic global warming theory because it makes you feel morally superior and don't oppose it because because you fear the political response of others.

Great find, Griff. It probably went under your radar because of the lack of reporting.

I couldn't find any place in the article where "less" was used questionably. Can you point me to it?

Griff 07-22-2003 10:10 AM

-When we are out of the arms and galactic cosmic ray strength is low, there are less clouds and the Earth is warmer.

Can I have a ruling on this?

dave 07-22-2003 10:13 AM

Fewer clouds.

Griff 07-22-2003 10:22 AM

Seconded. New business?

dave 07-22-2003 10:34 AM

A real easy tip-off is that "less" should basically never be preceeded with "are".

You use "less" when talking about something that cannot be quantified. "There is less soda than there used to be." is a proper English sentence. "There is less sand here than in California."

But if you're talking about specific objects instead of one big general thing - "There are less sand particles here than in California" - uh, no. So that's when you use "fewer". "There are fewer sand particles here than in California."

I commonly made this mistake up until about two years ago, until I thought about it, and now I catch other people doing it all the time while completely avoiding it myself. It's really a simple re-training of the brain.

Fewer dogs, less dog shit.

Griff 07-22-2003 11:02 AM

Fewer vs less is one of those things which I naturally detect and find annoying but I usually don't say anything since I'm so sloppy with other aspects of writing, like throwing commas around like rice at a wedding. These kinds of errors chip away at your credibility, which is especially important when what you're writing is highly technical and you want to be perceived as an expert.

If these are the same guys I read about in the WSJ last Monday, then they have some credibility problems. One, the paper was very subjective and short on specific numbers. Two, they refused to provide raw data to peers for analysis. Three, they refuse to answer questions beyond saying their paper speaks for itself.

In the meantime, this is the data that were being discussed so subjectively. Notice how temperature rises are associated with CO2 levels, and the sharp and unpresidented temperature change only in the past 100 years:

xoxoxoBruce 07-23-2003 09:45 PM

OK, so the CO2 follows along with the temperture changes. At least at Antartica.
And I see several temperature changes as or more precipitous as the current one. Higher peaks too.

Right. In the big chart, the CO2 _follows_ the temperature changes. And the peak is not only not unprecedented, it appears that we're about due for one anyway.

But there are less of them then we.

Yep, I'm a grammar Nazi as well. :D

As a quick rule along with Dave's, use "fewer" with countable nouns (ie people, cars, clouds), and use "less" with uncountable things (ie love, conceptual money, Canadians).

Actually, it looks to me that the temperature change follows the CO2 change. Look where the upswings start for CO2. It is already on the increase when the temperture curve starts going up. And as far as I can tell, it is the CO2 spike that is unprecedented, not the temperature (is that what you meant, tw?).

And in any case, there's really no point at all in debating it.

As the chart clearly shows, we would have to return to pre-industrial age levels of consumption in order to prevent this phenomenon. If that were to be implemented, billions upon billions of people would die of poverty, as the earth can't support this many people without things like transportation and the modern energy grid.

I think that studies like these really give some insight, but are they really necessary

The chart show nothing of the kind. Using same logic used by Undertoad, the chart shows what happens when too many people now commute alone by 2 ton car from Pennsylvannia to New York City every day. But we need those people to drive two hours each direction at over 100 km/hr to keep the world from starving!

Since we could not save the Columbia, then we also should not have tried to save it. I hate such defeatist reasoning. It defines the classic anti-American - person who fears to innovate - who fears to address problems - whose solution to problems is to always give up because the problem certainly cannot be solved or even minimized.

Instead we should spend even bigger buck on an anti-ballistic missile system to save us from a threat that does not exist. Clearly its better to spend massive funds on something that is flawed and no money on technologies we know work.

That 'woe is me so don't try to fix it' reasoning is offered by UT in response to the chart. That was also same reasoning offered as an excuse when engineers desperately tried to save seven shuttle astronauts.

CO2 levels don't have to rise this quckly. We know the technologies exist for more productivity using less energy and pollution. Thank the Japanese and Germans for rescuing so many technologies that sat stifled in America. Of course they now a have all those jobs.

BTW, have we noticed all the heavy blue and black smoke now pouring from coal power plants in the region. Same reasoning that says global warming cannot be solved is also why all those scrubbers are no longer being used. We cannot clean the air enough so we should not clean it at all - George Jr reasoning.

Again, same reasoning used by UT to ignore realities of global warming. We can't solve it today so we should never try. Its called being an anti-American - a quitter - an ostrich. Global warming exists. Many solutions to global warming means greater productivity - except to quitters.

That is NOT what he said or even implied.

No. I work 200 yards from one of the biggest coal plants in the area and haven't seen any increase in visible particulates.

But, we don't have conclusive evidence as to why or even that it's bad.

I think newer technologies can provide significant relief without too much hardship. For example, the Energy Star program for appliances, including computers and periperhals. claims the following

Results are already adding up. Last year alone, Americans, with the help of ENERGY STAR, saved enough energy to power 15 million homes and avoid greenhouse gas emissions equivalent to those from 14 million cars - all while saving $7 billion.
from EnergyStar.gov

Most of us didn't even notice the changes made. Changes to simple technologies, like two-stroke engines, can add up to massive environmental changes. Fuel cells are on the horizon, and electric-gas hybrids are already available.

The environment is the ultimate 'tragedy of the commons'. Even a Libertarian 'leave everyone alone until they affect their neighbor argument' does not deal well with pollution.

If I have a 55 gallon drum of toxic material on my property, I have the potential to harm my neighbor. Since I haven't harmed my neighbor yet, in a strict 'wait until it happens' sense, some people might argue to leave me alone.

However, considering the difficulty in reversing or repairing the damage, requesting a bond would be impractical, because cleaning up a spill after it leaves the drum would cost more than I could probably afford.

So we are left with environmental damage in the name of progress without accurately assessing the cost. Texas has some of the worst air pollution in the US. Some people feel that toughening requirements would hurt the economy, without considering the economic cost of smog alerts, lung diseases, lost revenue from people staying indoors, etc.

Some communities ignore enivironmental issues until the company folds or leaves town and they are left with a burning underground coal mine or dead mountain, polluted waterway, etc.

Essentially, clean air, water, and soil are a common property. Our current policy of giving away these items for short term prosperity is essentially in line with the current adminstration's economic policy, a matter of us writing checks that our future generation will have to cover.
