Are humans alone the cause of global warming?

Question

Are humans alone the cause of global warming?

Answer 1

There is no global warming, so let us humans eat drink be happy

Answer 2

No we are not. First of all the earths average temperature hasn't change much since 1997. The IPCC is just a bunch of corrupt scientists who can make more money lieing then they can working. Co2 is less then 3 parts per million in the environment. A volcanoe can cause more tan we do.

Answer 3

Don't forget volcanos!!!

They release tons of toxic stuff in the air when they erupt.  

Answer 4

No. Animals are to do with it as well.

Also, I believe that global warming is part of a natural cycle. I think we are however, making it a lot worse than it would have been if we'd know what was happening earlier.

Answer 5

yes because of our carelessness we have ruined the world and most people dont care enough to try and change

Answer 6

you know, i am a strong believer that global warming cant be avoided. no matter what happened (the creation of humans through evolution, or god, or whoever) the sun would hit the earths atmosphere, and destroy the ozone layer. so maybe us humans are making global warming happen faster, but were definately not the cause. its natural

Answer 7

No, i think cows have to take much of the blame

Answer 8

Here is truth about global warming:

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.

The worrisome and brutal predictions of drastic climate effects are based on computer models, NOT CLIMATE HISTORY.

As you probably know, computer models are not the most reliable of sources, especially when used to 'predict' chaotic systems such as weather.

Global warming/cooling, AKA 'climate change':

Humans did not cause it.

Humans cannot stop it.  

Answer 9

Ok what Stu T  has got to be one of the funnist things I've ever read. hahahaha

And yes humans are the ones to blame.

Answer 10

All the imbalance in nature is due to Humans. If possible try to avoid as much as pollution as you could else the D Day is not far. Do watch this movie its a real eye opener An Inconvenient Truth: Al Gore  

Answer 11

i rekon we have just accelerated the process...so whats ment to take hundreds of years is taking tens of years...

Answer 12

Humans have had absolutely nothing to with any warming period and there has been no warming for over 70 years now. Well up until 1934-40 it was real and it happened because of the end of a period of low sun spot activity and the beginning of a more active period of solar output. It has been well proven now through current and historical records that the overall temperature average or climate of the earth is closely tied to the sun spot activity that directly affects the earth’s climate. Real global warming is a natural cosmic event, the global warming currently in the public spotlight is a fictional event brought about for political and economic gains by an elite group of con men.

The whole concept that this global warming scam is built on comes from a mistake in logic by a chemist back in the late 1800s when things started warming up at the end of the 2nd half of the little ice age. His arguments were adopted by a group of anti-industrial/anti-technology religious fanatics known as Luddites after their prophet to try and return society to its grander days in the early medieval period when nobility meant something. Oh yes, just like today the major adherents of this cult were the 2nd and 3rd sons of the minor nobility and in some cases the 1st sons who had squandered their inheritances on life style instead of productivity.

The anti Co2 cult was enhanced again when the argument was taken up during the late 20s when warming became noticeable and a industrial chemical firm had come up with a fluorocarbon instead of an oxycarbon refrigerant they claimed was not only superior to Co2 as a refrigerant it also would end the threat of global warming caused by Co2. This refrigerant was known as Freon and was in recent years banned because it was suspected of damaging the ozone layer. Now because of the low performance of other substituted refrigerants Co2 is making a huge comeback in the refrigeration industry, especially in newer auto air-conditioning systems that are more compact and efficient.

In the 1970s the Co2 equals warming theory was once again brought forward by a couple of low end climate scientists Mann/Hansen to first warn of the immanent plunge into a new and disastrous ice age because of the production of Co2 by vehicles and industry. This even though it got major media news play flopped like a lead balloon. Then they got involved with a shyster politician that had major oil company connections dating back to his fathers involvement with them who said clearly people are not afraid of cold but they are of heat.

So this politician writes a disaster is coming because of the warming that will be caused by the huge amounts of Co2 the world is pumping into the air. Mann/Hansen then revised their materials to forecast ever rising temperatures in sync with rising Co2 levels. Well when they checked closely they found that world temperatures had no relationship with Co2 levels and instead followed sun spot activity so they had to alter world temperature records to reflect a temperature increase matching the Co2 increase. This worked fine up through 2000 because things were warming up after the 70s cool period at that time. Then after 2000 temps leveled off and started dropping a little and their altered temperature curve that matched the increasing Co2 curve began to radically separate from reality even more than it had from the beginning of the scam when they had interjected an artificial .5C jump that placed the current 1998 peak well above 1934 when it was actually about .1C below 1934. This radical difference between actual recorded temperatures and reported ones quoted by Mann/Hansen is what brought about NASA action to review national and international records. The US national records have been repaired and now reflect the fact that global warming is more than a myth, it is an outright con game played for profit at the highest political and economic levels.

Answer 13

Definitely not.  There are many causes:  sun cycles, methane emissions from under the ocean, changes in absorption rate of vegetation.

Answer 14

no, animals do to

eg. cows produce co2 whenever they f**t

Answer 15

No it is scientfily proven that humans have very little impact on the earth, F earth day

Answer 16

no, it has been happening for millions of years, but we have simply sped it up

Answer 17

Cutting down tropical forests to create fields for burger cows doesn't help.

Volcanoes emit more C02 and other gases than industrial polution.  Things were in balance, its just that humanity is tipping the balance toward global warming

Answer 18

Yes, 100%...with the industrial & technology revolution this concept of global warming came to the earth..Prior to that animal also were there but we have never faced any problem called Global warming...when we burn animal waste and corps they called it biomass which hardly effect the ecological system. It's only human who creat so much trouble for his own comfort and now started asking stupid question like this...of course it's human...specially US who is causing major Pollution...

Answer 19

global warming happened millions of years ago did anyone figure it was technology that caused it back then if there is no evidence? because i'm sure the dinosaurs weren't all driving SUVs, using aerosol cans and heating tar pits with oil across the land...

Answer 20

Yes off course. Human does.

Answer 21

Humans are not the cause at all. Global temperatures have stopped rising over the past 7 years while CO2 levels continue to rise. Global warming is natural and there have been more extreme incidents of it in the past before the industrial revolution. There is NO evidence of man made global warming. I'm not saying we keep polluting, because that pollution isn't doing any good for the environment, not to mention the energy crisis. We definitely need to cut back on energy use, but global warming is not man made.

Answer 22

We're not the sole cause, far from it. There are all kinds of factors that can cause the climate of the Earth to change. Unfortunately, climate change denialists exploit this complexity to argue that human activity is having a neglible effect.

John, your assertion that volcanoes produce more CO2 than industrial pollution is not supported by the evidence. On the contrary, human-produced CO2 far outstrips that produced by volcanoes.
