Higher CO2 levels may be good for plants: German scientists
The dangerous rise in greenhouse gases in the atmosphere may be troubling scientists and world leaders but it could prove to be a boon for plants, German researchers said Tuesday.
Increasing exposure to carbon dioxide appears to boost crop yields, Hans-Joachim Weigel of the Johann Heinrich von Thuenen Institute for rural areas, forestry and fisheries in the central city of Brunswick told AFP.
"Output increased by about 10 percent for barley, beets and wheat" when the plants were subjected to higher levels of carbon dioxide, Weigel said.
The Thuenen Institute, which has been monitoring the phenomenon in fields since 1999, trains CO2 jets on the plants so the gas reaches 550 parts per million in the air around them — the level expected in the atmosphere by 2050.
Weigel said the studies have indicated that while greater CO2 exposure appears to spur growth, it can also undermine the quality of the produce.
He said the next step in the study would be to evaluate the effect of higher temperatures on plant growth — which scientists cite as another consequence of higher CO2 emissions in the atmosphere.
Weigel said that while the institute's findings may prove surprising to some, they are not intended to undermine the drive to slash CO2 emissions.
"This research is not intended as an argument for doing nothing to curb the rise of CO2 levels," he said. "It is to find out what the effects would be."
Other studies have presented a more mixed picture about the impact of higher CO2 levels on plants, and there is uncertainty about its effects on soil fertility and which plants benefit most from more CO2.

FIRST HOLLER
Leo is yummy
wow interesting
who knew
first
mmmmm CO2
first
HOTHOTHOTHOT.
MMM
first
first
first!
wow 1
1st!!! What does this have to do with Leo????
exactly! another reason why world wide deforestation is never a good thing
Ok i get the article.. but what does Leonardo have to do with it?
Help??!
Tokio Hotel rules my life…best band ever
You know what I find interesting perez, you post stories that I read on other sites hours after they've already been posted, especially stuff on other blogs, like rashmanly.wordpress.com
Whats up with that?
Considering trees breathe CO2 I'm gonna have to go with a big ol DUH on this one.
Global warming is a scam.
Whats this have to do with Leo?
SOMEONE GIVE THIS MAN A FUCKEN OSCAR ALREADY HE DESERVES IT
LOVE YOU LEO
Re: Jacqu –
Trees don't breathe honey
Leo did an Al Gore style documentary on the effects of global warming last year. Jeez guys.
Re: Ella –
you have to finish the 2nd grade, darling!
so what perez is awesome
you're an idiot.
if you love plants so much maybe you should buy a patch of the Amazon rainforest
I see this great picture of Leo, but the only thing under it is an article that has nothing to do with him… I mean, I know Leo's an enviornmentalist and he's probably reacting to this news as we speak. But still, what a bait-and-switch!
leo looks beautiful
Re: Ella – yes, trees breathe,,,everybody knows that!!!!!!!!
Re: Ella –
Carbon dioxide is produced by all animals, plants, fungi and microorganisms during respiration and is used by plants during photosynthesis.
You're welcom.
wow
Greater CO2 = bigger & better pot plants. Yeah CO2!
LEO MARRY ME AND FUCK MY VAGINA ALL NIGHT LONG SEXY!
Al Gore go fly your Jet over crops and help the poor farmers.
hun your really good lookin your mama made a hottie and could i just say that you looked so hot in Romeo and juliet
Re: Jacqu –
they utilize it yes, but not through the active respiratory proccesses that other organisms do. Photosynthesis is passive. It is not the same as breathing
oh my god only in america would someone spend this around…obviously large amountsof co2 isnt good for the atmosphere…they only wanna make what their doin ok and its not…ppl r so dumb…dont believe this bull shyt
um DUH we learned this in 2nd grade, if not earlier, that most all plant life thrive off CO2, as humans fo O2.
if this is news to anyone. wow youre retarded. just goes to show people dont take time to know shit about shit and just follow whatever idiot's opinion they might read in the paper. or on PEREZ HILTON. (god fuckin forbid)
global warming is a scam.
ummmm dont plants use co2 to start the photosynthesis process…i remember from elementry school that plants give us oxygen and we give them carbon dioxide…..smarten up….why is this amazing?
WHO CARES!!!! JUST POST MORE LEO PICS!!!!!!

Green is good! If anyone really wants to help, water is for sure a priority! This is a new company and will be giving 7 percent on every unit sold to a deprived area in the US and Internationally. Over 1.7 billion do not have running water, not including contaminated water! Visit www.puritywatersource.myxziex.com for a very good cause!
So, oxygen only makes up a tiny portion of what we call "air." We breathe in a much higher concentration of nitrogen. Oxygen is a highly flammable element. To have more oxygen produced isn't really a good thing. Plants do not in fact breathe, they respire.
First of all, if you know anything about biology, you know that CO2 is to plants as oxygen is to humans. Plants love CO2!!!! Plants hate oxygen, but need it in order to live. However O2 will kill them if it is not released back into the atmosphere, just like too much CO2 will kill a human if it remains in their blood stream for too long. Plants give off O2, which humans consume. Humans then give off CO2, which plants then consume. It's all cyclical.
I guess what I am saying is that not all of your readers are uneducated.
HELLO! Look at the bigger picture and don't post biased articles
Of course higher levels of CO2 are good for plants! That's shit they taught in elementary school. Then the plants make Oxygen for us. This whole "global warming" thing is a fraud, people! Wake up and smell the coffee!
anyone who has taken high school biology knows that plants consume CO2 and distribute Oxygen…wake up people…it's all a hoax…
I also want to mention how pathetic Leonerdo is by trying to pick up a "cause" to make him seem important. Next time try picking one that's not a scam, jackass. You also might want to not try to copy everything an idiot like algore does, including remaking his movie with your name on it next time. Oh, and stop sending out JUNK MAIL to my house with your name on it. Do you know about conservation and wasting of natural resources, you hypocritical douchbag!
CO2 at 1% causes drowsiness in some people. At 7%-10% death of any and all animal species exposed (including humanity) will occur within hours. The plants will love it, but no animal can survive it
Re: FReal – leonardo has been pro the environment from way before Al Gore did incomvenient truth. If you are going to bitch, at least have te minimum amount of info to bitch with/about
Re: info – PS Ever wonder why you get so tired now a days after driving on the highway or through traffic? CO2 at 1% emited from cars will cause drowsinss and add the carbon monoxided which is straight up poison and you will understand.
We learned this shit back in high school, so I going to echo everyone else and say "DUH"! When Gore started in on CO2 being a greenhouse gas, I then knew that global warming was a scam. Hypocrites like Gore love to tell us how to live, from their 10000SQ foot mansions and heated pools.
Re: … – the rate at which plants produce O2 from Co2 is not as quick as animals producing CO2 from O2 let alone the CO2 produced from more than jut breathing. Plant metabolism is very slow. In fact it is phytoplankton in the seas that drive the CO2 to O2 cycle and the phytoplankton is dieing off due to our polutants and shit from your toilet dumped into the sea. phytoplankton metabolism is prety slow compared to animals let alone the CO2 produced by other ways besides simply breathing.
Duh, plants breath CO2 like we breath oxygen, so it is not surprising more CO2 might make plants grow bigger and faster. However, that is a seperate issue from the fact that increased CO2 levels in the atmosphere are also changng the weather patterns of the globe to devestating ends. Wait until Miami is under water in 50 years, then tell me how much your larger geranium plant was really worth.
just another proof that americans are stupid… comments here are so stupid… back when global warming was a hypothesis, it was the american scientists who set out to prove there's no such thing. now it's a fact, there're still ignorant stupid americans who think it's a fraud. the greatest polluters in the world!!!
Re: Becks –
If Miami is underwater, it won't be underwater because of anything people did. Did cavemen cause the ice age or did they just end it?
Global warming is a scam to the point that people who try to brainwash kids into believing it ought to be charged with a crime.
Re: ??? –
Yes, now it's a "fact". You are projecting, because you are the ignorant one.
Who gives a flying fuck if Miami's under water? By the way, you idiots buying into the global warming/climate change garbage are unbelievable. The big stink is rising sea water, right? Meaning what? A lot of coastal cities and neighborhoods would be under water. Right? Umm, so fucking what? So those people move a little further inland. So REALLY, you're problem with "climate change" is economic…..the same thing you accuse those of who don't buy into the BS. Oh, and the fucking polar bears will just move to colder climates.
btw, Leo's kinda Eddie Munster-ish.
without an atmosphere there are no plants…. co2 affects the atmosphere. therefore the result of the research is useless and stupid.
How soon we forget!!!!!! Didn't we all learn in school, plants take in carbon dioxide and give off oxygen?????? ENOUGH SAID!!!!! The equation has not changed since time began here on Earth!!! Any changing are charging for carbon dioxide is made up bullshit!!!!!! It's a normal natural process, but just remember "take away carbon dioxide, and you take away you and me"!!!
We could have 6 millions more times carbon dioxide going on outside and it would be amazing completely lush and fruitful and minding blowing breathtakingly beautiful outside, which in turn would make us completely healthy and pretty much super human, life and food would prosper and excell in every area!!
who cares if co2 is good for plants? it's bad for anything that breathes.
Are you serious?
We need more random Leo - YUM!!!
wow
i had no idea
AND LEO MADE A MOVIE ON GLOBAL WARMING PEOPLE
:D
i luv him
give him a oscar
leonardo dicaprio: global warming- HAWT
HAHA
Why show the picture of this ozone head??
Re: Ella – Stop trying to big yourself up. Accept you made a schoolgirl error.
Re: ??? – I'm British and I believe global warming is a scam.
Go to Google and search for "The Global Warming Test." This will teach you the truth about Co2 levels, and how during long ice ages there were higher Co2 levels than today. In fact, there's absolutely no proof that Co2 levels contribute to Global Warming at all. We're actually much closer to another ice age than we are to getting really hot.
I forgot to ad - when you search for "The Global Warming Test" on Google, make sure to click the first one on the list - the one from "geocraft."
Just today my local newspaper stated that we humans are the "blight" on the natural world! Fuckers!
Unfortunately you need to understand the science before you post things like this. Yes, the plants grow faster / get bigger, but they contain less protein. This impacts the food chain all the way up. It is sad that you are treating science headlines as if they were stupid stories about Miley Cirus or whatever her name is. Global warming is a serious threat to life as we know it. It is not a political issue, it is science. Please don't cite things like this unless you have read the article in a peer-reviewed science journal.
Re: Jacki – o we could not have 6 million times more CO2. CO2 at 1% of the atmosphere will make most people drowsy and at 7%-10% will call ALL animal life on earth. CO 2 in large amounts is great for plants but bad poison for animals. Plants can not convert CO2 to O2 as quickly as we are making CO2. Crack a science book and put away your bible.
As a scientist, I'd like to clear this up for your readers who believe "Global Warming" is fake. P.S. it's no longer called "global warming" - it's "global climate change" now. Earth has kept itself in balance for millions of years now. Oxygen and Carbon Dioxide levels are constantly changing. In a response to increased carbon dioxide, plants flourish taking in the greenhouse gas to produce oxygen to balance out earth. With deforestation and urbanization, there are now less plants to naturally balance out the atmosphere.
Re: info – srry for typos o =no call = kill etc
Leo is gay for the record - don't let his p.r. team fool you.
um duhh co2 levels increase plant life it has already been documented in the carboniferous period where co2 levels rose to extreme levels and luscious plant life proved to be abundant (where humans were nonexistent). High levels of co2 in the atmosphere is dangerous for human beings to live thats why we are urging the reduction of these emissions in the first place, it has never been doubted that co2 has a positive effect on crops (hello photosynthesis only works off of co2)
Did you know that TEMPERATURE causes CO2 levels to rise-not CO2 levels cause TEMPERATURE to rise?
Fuck Al Gore for making us believe his crap.
It really depends on the type of plants and whether they are C4 or C3 plants (this has to do with the dark reaction of photosynthesis and overall efficiency for the plant). C4 plants won't be as greatly affected as C3 plants would be (C3 being most of the plants in temperate conditions outside of the equator and many crop plants). C3 are less "efficient" than C4 plants and therefore there is a greater effect on them.
I've done a similar experiment to what these researchers did and found similar results.
Your readers who think global warming is a scam are FUCKING IDIOTS (yes, FUCKING IDIOTS). Yes, plants do need that CO2, but the fucking acid rain, large storms, unusual seasonal changes, etc caused by pollutants will kill them off before they've had a chance to make use of all that CO2. Furthermore, there is only so much CO2 a plant at any time can synthesize.
Besides, okay, say the plants live. We still won't. We need more than plants and oxygen to live. So……. NEXT!
what about CAM plants chacho?
Re: Envir –
It's so hilarious that because temperatures have been dropping for the past several years, now these assclowns had to change the name to "global climate change"! LOL…keep changing your story…it's waaaay more believeable that way!
Why don't you all go put on your purple nikes and drape a cloth over your head and wait for the mothership to come pick you up?
don't post environmental/scientific info when you have no clue. Yes, plants breathe CO2 and produce O2, duh. But, most plants need a silly thing called water, which decreases as heat (caused by increased CO2) increases. They also tend to burn up in hot temperatures; not so good for living. So unless we want all succulents (think cactus), it's not a great idea. This is bullshit propagated by the agricultural industry, as well as energy energy which wants to maintain status quo, to prevent any actions towards limiting global climate change. Please be a little more responsible.
Seriously Perez? Any indoor grower worth his/her salt has a CO2 burner in their garden. You can double the size of plants, practically overnight. Even if you just have a cannister of CO2 that you squirt off once or twice a day your plants will benefit.
Again! Please visit www.puritywatersource.myxziex.com! Not for the stupid people leaving messages! What are most of the logins saying? Nothing!
duh! plants need co2 for photosynthesis, its not new.
Pot growers already know this. That's why they pipe the shit in to make their plants grow faster, bigger, healthier…Global Warming is bogus; total propaganda and based on some bad science.
Only in America would the media cover the "upside" of global warming…
I love it when people say global warming is a fraud. Science that's not funded by oil companies much?
The earth herself goes through cycles, sometimes it's hot, sometimes is not as hot. Check out the little ice age that occurred round the same time as the plague was ravaging Europe and Asia.
HOWEVER, the industrial revolution sped everything up. We as humans have been using resources that are FINITE and dirty. What in the hell is so wrong with wanting to make the world less dirty? To be responsible and realize the we don't fucking OWN this planet, we're just visitors for christ sake!!
I'll bet plants will not grow well in 150 degree heat no matter how much CO2 they get.
Plants will not grow well in 150 degree heat no matter how much CO2 they get.
wow perez you dumb fuck. anyone who knows anything about fucking photosynthesis could have figured that one out.
You want to know another reason why global warming is a TOTAL SCAM??!! CO2 is heavier than all the other air molecules up there, heavier than Nitrogen, Oxygen, Helium, etc. CO2 SINKS TO THE GROUND!!! The whole basis of global warming is too much CO2 in our atmosphere which is a load of crap since IT SINKS TO THE GROUND!! If it didn't sink to the ground, plants couldn't use it as food. If you are a miner you learn this VERY important fact in training because if you are in a very deep hole, you need to be wary of CO2 poisoning because it sinks into pits very easily and very fast. GLOBAL WARMING IS A SCAM!!
L is GAY
I will marry Leo
I heard that the change in sun spots is causing the earth's climate change, not carbon dioxide levels. I suppose we'll never know as data can be manipulated to tell any story the media wants told. Believe me, I work in Finance and am quite fluent on how to spin many different stories on the basis of one set of numbers. We need to focus on finding alternative energy sources to lessen our dependency on foreign oil and leave the global warming b/s off the agenda tables. I wish people would separate these issues.
well, i must say i'm enlightened by all the "Global warming is a scam" comments. i guess it's all a plot out to make people reduce, reuse, recycle… the kyoto treaty is a plot by all nations in the world to make nations not pollute, make the world cleaner and reduce co2 emissions… help me out here guys… what does al gore hope to achieve by this? wasn't the treaty signed way before live earth? i'm so ignorant that i didn't realize that people who cry scam are the lazy ass stupid americans, and everyone else included, to just consume and pollute and keep on churning out non biodegradable shit… their own load of toxic crap included.
I so want to fuck Leonardo… OMG HOT HOT HOT!
Re: Jacqu –
trees & plants in general take in CO2 for photosynthesis… not for respiration… that would be 02.
