Poison Ivy Itchier, More Plentiful With Warming, Study Says

[Crabtownboy]

I do not believe anyone would deny that mankind has caused an increase in the amount of carbon dioxide in the atmosphere. Whether you believe in global warming or not there is an unintended consequence caused by the increase in the carbon dioxide ... bigger and meaner poison ivy.

Global climate change may soon make our planet a much itchier place.

Rising levels of carbon dioxide—a so-called greenhouse gas that traps heat within Earth's atmosphere—can fuel booming poison ivy growth, a new study reports.

Even worse, the rash-inducing vines may become more potent.

Working in a Duke Univerity-owned forest near Chapel Hill, North Carolina, researchers used a system of carbon dioxide-pumping pipes to create atmospheric CO2 levels that were some 200 parts per million higher than the current norm.

Many global warming models predict that such levels will be a reality by 2050.

Poison ivy growth surged some 150 percent in the carbon dioxide-rich forest plots.

Good grief.

Just another slant to try to push a junk-science, discredited agenda.

This has to do with increased carbon dioside, not global warming. There is no question it is mankind who has put the extra carbon dioxide into the atmosphere. There will be other unintended consequences that will be discovered in the future.

There are always unintended consequences in whatever we humans do.

I read it... the article doesn't say what you want it to say.

It acutally says "can fuel booming poison ivy growth" and "the rash-inducing vines may become more potent".

IOW - it's specualtion - not fact.

It may happen in the future (or it may not).

And you need to read more. Oh, that's right, reading is dangerous as you may have to change your opinion. LOL

Fifty years of data is not future possibility. LOL

Buzz up!
Poison ivy has grown faster, grown stronger, and grown more resilient as the level of atmospheric carbon dioxide has increased in the past 50 years, according to new research. The project builds on a six-year study released last year that showed poison ivy would respond well to future increased in carbon dioxide, no matter how that gas influences global warming.

And listen to this interview .........

Lewis Ziska, plant physiologist for the U.S. Department of Agriculture's agricultural research service, says rising carbon dioxide levels and forest disruption are making poison ivy spread faster, grow larger, show up in new places and become more toxic. He tells host Michele Norris what makes the plant uniquely affected and how to treat skin that's been exposed.

For 6 years, scientists monitored plants that grew near some of these pipes in a Duke University pine forest. They found that, with about 50 percent more CO2 around, poison ivy plants were able to make more food and use water with greater efficiency.

Poison ivy plants that got the CO2 boost produced the same amount of toxic oil, called urushiol, as regular air-bathed plants. With extra CO2, however, more of the urushiol was in a particularly toxic form and more likely to cause rashes.

Poison ivy's success in the presence of extra CO2 is just one example of how climate change might alter the dynamics of forest ecosystems, scientists say.

Oh, I see.

In your attempt to laugh at me for pointing out that the article that you posted doesn't say what you want it to say...

You now put up other articles that I should have read before commenting on your OP?

I stand by my original observation - your OP doesn't say what you want it to say.

The other articles may - but your OP doesn't.

Now I may be wrong here, but I seem to remember something about plants (in general) thriving in a carbon dioxide-rich environment. Plants absorb carbon dioxide and release oxygen as part of photosynthesis.

So if plants flourish from the extra carbon dioxide, they will release more oxygen and lower the levels of carbon dioxide in the earth's atmosphere.

Therefore, as long as humankind doesn't destroy our vegetation, then our plants and trees will help regulate carbon dioxide levels.

It aggravates me to see science hijacked the way it is so often today.

Science is supposed to be based on facts gained through observation and testing. When I read that article I didn't see many scientific facts, I saw a lot of supposition instead, which is what many wrongly call science today. It can cause this, this may become more potent, etc. That's not science. Here's science: if I hold up a basketball and drop it, gravity will pull that basketball toward the ground at an acceleration of 9.81 meters per square second. Those are facts reached by observation and testing of the surrounding world.

Well, let's all pick numbers. If odd, we live; if even, we kill ourselves for the sake of poison ivy.

While I hate an outbreak of poison ivy-- and I have had quite a few-- I no longer try to get rid of the abundance of the plant that lines my back fences. I now regard it as an extra defense for anyone who may try to invade my property from the field behind it. If they recognize what it is, they will avoid it; if they don't recognize it, and try climbing over it, they will get their just deserts...unless they are that rare individual who is not allergic to the stuff.

Wow. Imagine that. Real science.

Give Crabby your textbook. He's not familiar with the subject.

(This also proves how utterly inane his argument is...all plants doing better in CO2-rich environment...but only poison ivy matters).


CTB, Al Gore called. He wants his broken logic back.

Whoa now, don't go bringing any real science into a discussion about global warming. It simply is not welcome.

 

[Rubato 1]

I know - from good science - that I am still not allergic to poison ivy as of last week... :flower: :tongue3:

Global warming- the Ruckmanism of the Science world.

At least Ruckman is beholden to some form of truth (I mean, at least it's the Bible).

These yahoos following Manmade Global Warming are pulling this junk out of thin air (or fraudulent emails...take your pick).
