is global warming real?

Question

is global warming caused by human co2 emmissions?or is it just a cyclic position of our world??

Answer 1

People emit CO2 every time we exhale, so should we just start killing people because of it? Should we buy a filter to wear to help this problem?
It is a cycle no one can control.

Answer 2

No, global warming is totally fake. 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.

Answer 3

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 global warming.
Humans cannot stop global warming.

Answer 4

Global warming and cooling trends are a natural occurrence. Is the present trend man made or natural? I can not see man as having the ability to affect nature that much. The CFC debate seems to prove man inability to effect nature on that large a scale. When Cf's were blamed for the hole in the ozone layer the amount of CFC produced by one volcano was 1000 times more than man ever produced, yet the hole repaired itself even tho there have been major eruptions since we banned CFC. If you look at the climate history of the earth beyond the last 100 years "which the climate models predicting doom don't or they ignore the middle ages warm period" one finds no record of the doom predicted even though the global temps were 5-8 degrees higher than today. In fact Greenland got it's name simply because it was a land of green not white.

Answer 5

A lot of people are saying both right now. A cyclic position that has been artifically accelerated by human emmissions.

I think it will be a while before we know for sure, but until then, does it really hurt to emit less? If I replace a bulb with a flourescent lamp, even if it doesn't save the environment, it does save my power bill.

Most of the things you can do are good and money saving regardless.

Answer 6

Until real-world evidence demonstrates it, and NOT computer models, then human CO2 emissions cannot be blamed for global warming trends. The only mechanism supported by empirical evidence is one of natural cycles - even then, we have not been able to quantify or account for every cyclic fluctuation.

Answer 7

do not believe something you study and in elementary terms a million/2 of what you notice. of path, international warming is genuine. The final Ice age has long gone away, has it not? So, we ought to have international warming. Do human beings make contributions to international warming? in all probability some small volume, in spite of each and every thing we are heat and we breath in oxygen and breath out CO2, we must be a piece of the priority. what's Al Gore going to do approximately it? Kill lots of folk? forever that's what Socialists do whilst they take administration of a united states. Is that extra effective than destroying their economy and inflicting hundreds of thousands to starve to dying?

Answer 8

Global warming is real, and mostly (80-90%) caused by us.

Here are two simple pictures of the science.

Temperatures going up:

The reasons why:

In the past natural things like the sun were the most important. But now our production of greenhouse gases has overwhelmed the natural causes. It's still not 100% us, but it is mostly.

The vast majority of scientists, and almost every scientific organization and world leader, accepts the scientific data as proof of man made global warming, although there are a (very) few noisy skeptics.

Answer 9

Is there a natural cycle of warming and cooling? - Yes.
Has man increased the levels of CO2? - Yes.
Can that increase exaggerate the natural warming? - Probably.
What is the best and quickest way to stop man made CO2 emissions? - Immediately go to all nuclear power.

Answer 10

In my opinion.. I feel that global warming is a natural phenomena. The amount of CO2 being pumped into the atmosphere because of human activity is speeding up this natural occurence.
