global warming?

Question

Are the man´s acts responsible for the global warming?

Answer 1

No, of course we aren't responsible for global warming....the idea that mankind can influence the climate in any meaningful (and dangerous) way is absurd.



The global climate is so complex that it is sheer arrogance to assume that mankind (particularly just "us Americans") can cause the devastation that the Global-Warming-Chicken-Littles are claiming we are responsible for. We don't understand the weather enough to predict it more than a few days off, much less do we have the capacity to foresee long term changes.



Thirty years ago it was global cooling, now it's global warming...not far off, they'll probably change it to any "severe" global weather so they can go either way in laying climate blame on man. That way, whenever it gets too cold or whenever it gets too warm or whenever there is a hurricane or earthquake or -- whatever -- they can point a finger and say it's our fault.



* sigh *. Okay, I'm getting worked up here. Here endeth my rant.

Answer 2

Nothing we do on Earth will help in any significant way. Mankind contributes a meager 3% to "climate change"



Let's all be thankful the Earth did warm a little. The alternative is far worse… Global Cooling… Mini Ice Age…



Global Warming Alarmists are merely opportunists jumping on the cash cow trying to earn a quick buck by scaring people into believing they are destroying the planet.

The same fanatics were screaming about "Global Cooling" in the 70's!! See this ===> http://www.glennbeck.com/2006news/newsweek-coolingworld.pdf



We have reached the apex of Earth's recent warming trend and we will gradually start cooling down again within the next 10 years.



I will be sitting here with my smug smile 10 years from know when all the "Global Warming" followers realize how foolish they have been.

Answer 3

No way.



Here...check out this website that's run by some really good scientists from Harvard-Smithsonian and professors from other prestigious institutes all over North America, www.friendsofscience.org. They really put up convincing and (reluctantly) UN Climate Report backed data that shows that Global Warming is natural and normal. They totally convince me that the cause of this natural temperature flucuation is the most simple source, the sun. For instance, for centuries, the sun has always intensified and weakened its radiation upon the earth, thus causing temperatures to change from century to century. During the 1400's, the Medieval Warming period took place, when temperatures were 3-4 degrees warmer than they are today! And after that during the 1700-1800's, we went through a little known Little Ice Age, when the temperatures dropped 1-2 degrees. Right now, we're only coming out of an ice age, so no wonder our temperatures are higher than they were 100-200 years ago. Which explains why they're still completely normal. And besides, in the sixties, when industry was reaching a peak, and carbon emissions were at an all time high, the temperature actually dropped! Scientists actually thought that we were going to go through another ice age. Yet, during the same time, the sun's rays weakened, thus proving that it was in direct correlation to the temperatures here on earth. So, to conclude, global warming isn't man-made, it's completely natural, caused by the sun.



Besides, anyone who really believes in global warming should just turn the a/c on instead of complaining about it...lol.

Answer 4

I don't think we know what we're talking about in less someone is an enviormental scientist that just graduated from Oxford or something but what i do know is even if global warming doesnt exist the exhaustion put out by cars and industialization isn't good. When i say 'isn't good' i mean unclean. and even if that won't destroy the earth it's self-it still isn't clean and should be stopped even if it means being a world-wide movement.

Answer 5

No, man is guilty of doing significant harm to his ecosystem, but he is not the culprit in "Global Warming".



Less than 1 degree increase in a century, but no one has been able to calculate the total Greenhouse effect in ANY year within 5 degrees, much less one.



Alarmists won't tell you that their hypotheses are meaningless without computer models, and they won't allow anyone independent analysis of the computer program or underlying algorithms - the one time that they did, they were uncovered as DELIBERATELY FRAUDULENT. They have never apologized for this.



No one here has access to these programs, but they say there is no doubt or that debate is over. Without being able to analyze the PRIMARY PIECE OF EVIDENCE, how can anyone make that claim.



We won't even get into the false claims of consensus, the dismissal and silencing of opposing viewpoints, or the incomplete collection of empirical evidence.

Answer 6

Global warming (and cooling) is entirely natural. Scientists discovered conifers and insects beneath the thick ice in Greenland, showing that even a country as cold as Greenland was once around 24 degrees celsius in the day.



We've been heating up for 10,000 years (the last ice age, global cooling), and over the last couple of hundred years, scientists have found that plants have smaller pores on their leaves, because they don't have to work so hard to take in Carbon Dioxide; there's more CO2 than they need. The results showed this -before- private jets and "a car for every home".



Don't believe the hype.

Answer 7

ABSOLUTELY YES.



Look at the temperature at 4 AM. Then man shows up on the highways at 8 AM and the temperature starts rising. While man is at work during the day, the temperature climbs even higher. Then finally man heads home around 5 PM and gradually the air temperature comes back down. When man finally goes to sleep, the temperature resumes cooler still.



It happens EVERYWHERE too! You can even go out with a thermometer and MEASURE IT!



So there's no doubt. The consensus is in, and there is no longer any time for debate. If we don't do something now, the earth will erupt in a ball of fire within... well, maybe as soon as 5 years even! But, if we all use flourescent light bulbs, the earth will be saved and the temperature won't do that anymore.

Answer 8

Global warming is one-half of the climatic cycle of warming and cooling.

The earth's mean temperature cycles around the freezing point of water.

This is a completely natural phenomenon which has been going on since there has been water on this planet. It is driven by the sun.

Our planet is currently emerging from a 'mini ice age', so is becoming warmer and may return to the point at which Greenland is again usable as farmland (as it has been in recorded history).

As the polar ice caps decrease, the amount of fresh water mixing with oceanic water will slow and perhaps stop the thermohaline cycle (the oceanic heat 'conveyor' which, among other things, keeps the U.S. east coast warm).

When this cycle slows/stops, the planet will cool again and begin to enter another ice age.

It's been happening for millions of years.

Humans did not cause it.

Humans cannot stop it.

Answer 9

Simply, no.



Most (99.5%) of the global warming would be happening even if mankind never existed.



Most of the g.w stuff is bogus anyway..



The 'real' science of which uses 'valid' data for its climate models, proved it several times over.

Answer 10

Yes, emissions of GHG's are effecting the climate. To those claiming it is a natural cycle (solely): Historically CO2 has lagged 200 - 1000 years behind the rise in temperature. It has, in the past, acted as a very strong amplifying effect to global warming. The initial cause has been various natural cycles. Now we see a direct correlation between the rise in CO2 and in temperature. As humans release CO2 in to the atmosphere it traps more heat on Earth. This leads to more CO2 being released (as in the past), thus CO2 is presently both a cause and a strong amplifier.

Greenland was, during the MWP, close to or just as warm as today. This was, however, a regional warming, not a global one.

Answer 11

Some are mans fault like using aersol cans contaning cfc's, and of course detonationg atomic weapons in the atmosphere, but alot of it I believe is a natural cylce the earth goes through on its own ever so many years

Answer 12

you just got here

that is what all the debate for the last 6 months has been about

Global warming is a Natural cycle that has gone out of control because of Human behaviour



And some people are making even worse

Answer 13

There is no global warming ,it is a scam. Ok lets say U could eliminate all CO2 would u be satisfied??? That would kill of all plants and thin we would die. I think U need to research it a little better. CO2 is not a pollutant ,it is just the way Mother nature marks it for recycle.

Answer 14

Yes.



1. CO2 is increasing in the air at an exponential rate, with no sign of slowing down.

http://www.esrl.noaa.gov/gmd/ccgg/trends/

2. The amount of CO2 in the air has increased 37% since the industrial revolution.

http://www.ncdc.noaa.gov/paleo/icecore/antarctica/law/law.html

3. This rise is caused entirely by human beings. Isotopic analysis of the CO2 in the air shows that it increasingly contains "old" carbon combined with "young" oxygen.

http://www.realclimate.org/index.php?p=87

4. CO2 is a greenhouse gas which causes the planet to warm. This has been known (and unchallenged) since the 19th century, so I won't post a link.

5. The planet is actually getting warmer.

http://hadobs.metoffice.com/hadcrut3/

http://data.giss.nasa.gov/gistemp/tabledata/GLB.Ts+dSST.txt

6. Natural climatic forcings can be ruled out as causes of the current warmth:

(6a). Ice ages and inter-glacial periods are triggered by small changes in Earth's orbit, called "orbital forcing." Since Earth's orbit can be computed for thousands of years into the past and future, we know that orbital forcing peaked 6000 years ago, and should be slowly cooling the planet right now.

http://www.sciencemag.org/cgi/content/abstract/207/4434/943

(6b). Solar activity peaked in 1988, and has declined since that time, even as temperatures have been rising. Cosmic ray flux, which some scientists have speculated causes cooling, has increased since 1988 as temperatures have been rising.

http://www.pubs.royalsoc.ac.uk/media/proceedings_a/rspa20071880.pdf

7. If the warmth is due to the greenhouse effect, we should see the stratosphere getting cooler as more heat is trapped at the surface. This is in fact exactly what we have seen. This also refutes non-GHG causes for the current warmth.

I invite you to compare the quality of sources cited in this answer with anything cited by GW skeptics. Then draw your own conclusions.

Answer 15

You should watch this video about global warming!Its funny!



http://www.youtube.com/watch?v=SgE_mkR2oac

Answer 16

Yup, primarily hot air from blowhard politicians. . 1/10th of a degree in the last century.

Answer 17

YES IT IS. RECENT STATISTICS IN THE INDUSTRIAL DEVELOPMENT INDICATES A DRASTIC RISE IN CARDON, NITROGEN AND SULPHUR EMMISIONS. THE MORE INDUSTRIALISED A COUNTRY GETS, THE MORE EMMISSIONS AND HENCE MORE GASES ARE PRODUCED. IF MAN KEEPS CUTTING DOWN VEGETATION ALSO, THERE WILL BE NO SINKS TO HELP DECREASE GREEN HOUSE GASES AS DESCRIBED. THESE GASES BUILD UP IN THE ATMOSPHERE AND TRAPS RADIATION WHICH HEATS UP THE EARTH CAUSING MAJOR PROBLEMS IN THE ENVIRONMENT

Answer 18

No we are not.



If we are the cause and if we are the answer..........we need to stop Continental Drift, earthquakes, hurricanes, tornadoes and volcanic eruptions! lol!

Answer 19

its just a stage in the world, it will get cold, its like a pattern

Answer 20

nope.

Answer 21

Hell yes, we've produced more pollution than ever before now that we have become so industrialized and selfish.
