Is Global Warming a natural trend?

Question

Please list why you think either side.

Answer 1

Why don't you go outside and start taking some temperatures.

Answer 2

You can propose natural causes, which seem logical. But, if you do the scientific analysis with numerical data, they prove to be minor factors at most.

The numerical data clearly says it's not natural.

There is a natural "carbon cycle" which recycles carbon dioxide. But it's a delicate balance.

We're messing up that balance by digging up carbon the natural cycle buried over a very long time, and burning it really fast. That overwhelms the natural process.

You can see it clearly in this carefully measured data.

The small teeth are the natural cycle in operation. CO2 goes down a little during the summer, when plants are active, and up a little in the winter. The huge push upwards is us burning fossil fuels.

Volcanoes emit less than 10% of what man does, and because of dust emitted, contribute less than nothing to global warming.

Increased solar radiation is 0.12 watts per meter squared. (It's been measured carefully many times by different scientists) Increased heating due to man produced CO2 is about 1.7 watts per meter squared, more than ten times as much.

The world's climatologists generally agree that (mostly) man is responsible. They don't throw logical arguments at each other, they analyze hard data. They include all the natural causes that have been suggested. The data says it's us.

The oceans do release CO2 as they get warmer. But it's not enough to explain the measured CO2 levels. It might be enough to make this thing spin out of control faster.

Answer 3

Scientists have confirmed that Earth has undergone many cycles of natural global warming / cooling over many millions of years. The best evidence of this can be found in core samples of ice taken from beneath Earth's poles where patterns of climate are permanently written.

Answer 4

Yes, it is very natural (so is global cooling for that matter). However, we humans are believed to be accelerating it be a factor of 400 without any consideration of the possible consequences. When we humans do things like add greenhouse gases, we may be ruining a delicate balance between nature, and we do not know when we hit a switch causing something drastic to occur.

Answer 5

no only humans made CFC's and releaded them into the atmosphere. We must clean them up. That is why I sent this letter to Al Gore:

Putting the technology together to start cleaning up and reintroducing new ozone to the atmosphere is possible. The cost and size of this project means taking a long term commitment. I am proposing the biggest cleanup in history. Al, I do not see any proposal that is realistic or proven at any cost, not even Washington can solve this problem. But if every person on earth does his or her share, we may be ok. Never-the-less, I see governments acting like a deer in a car’s headlights and people doing the same thing. The inevitable is almost upon us. Cleanup and change is the only option.
The first cleanup machine starts with a ten billion dollars investment. Ten year later with twenty-five machines operating, these machines will produce enough ozone to replace both holes at the poles. But more importantly, these machines will remove chemicals that deplete the ozone. Beyond making ozone, decreasing the poisons that deplete ozone, these machines reduce the major greenhouse gases and unbelievably we can have all this for fewer than one hundred billion dollars.
Beyond cleaning up our atmospheric mess as I am suggesting, we humans must do a better job reducing or cleaning up carbon monoxide, collecting and storing methane and ethane for fuel, burning less of everything, cleaning up our forests and using more solar insolation. Solar steam electric generators are the type of systems we need and are 90 percent efficient and near 100 percent if heat recovery is used. I believe nearly 30,000 MW are needed in the USA and Mexico over the next 30 years. This opens the door to new electric cars, new construction vital to our way of life, new bullet trains, and these industries produce new high paying jobs. From small scale solar generators on malls, to 2000 acre collector sights, these systems are viable and ready for production. The Federal Government must give up some land, money and have less regulation to help save the planet from disaster.
Al, spreading the message that we can help ourselves is a key to the development of these businesses. Washington can help: the businesses need grants, patents, land and regulations. Congress must create a pollution surcharge. From gas, coal, diesel, wood to cooling towers, from cattle, other ranches to cigarettes, from agriculture burning to airplane passengers, this surcharge can fund parts of these projects and many stationary pollution control devices in general.
Your personal support is very important to getting the atmosphere cleanup started and developing sights for solar generators.

Sincerely,

Answer 6

It's not a trend, but it's something that has been there for a while now, but only recently, scientists and the media started giving it more coverage and focus on it more then they used to.

Answer 7

Global warming is a natural trend, but we are also quickening it with our everyday habits and fuel consumption. It's a natural trend because it has happened numerous times and we are causing it to happen faster because we have damaged the ozone layer which keeps the sun from melting the earth.

Answer 8

Instead of wasting 5 points why dont you click on the Discover button. This question has been answered many times before.

Answer 9

No. It's caused by the burning of fossil fuels, which burn holes in the Ozone layer. Therefore, the sun goes through the holes and is able to melt the ice caps. As the surrounding water around the ice cap melts and becomes warm, it melts the ice in it. It's a chain reaction, caused, of course, by us burning certain fuels.

Answer 10

depends . if you work in the oil or coal industry , it's all natural .if you are a scientist with no profit motive it's a man made disaster that will kill us all .
