global warming fact or fiction?

Question

Was at a party, this past w/e. And a bunch of "high class" know it alls were upset with me. Why? because they cannot see how I cannot see that "Global Warming cue to pollution is a FACT!" Why are people such "followers of the media?
There are so many factors that effect our planets' temperature
more so than pollution: ie/ Solar flares (frequency highest in the last 15-18 years). Volcanos. Methane released by decay and by animals (agriculture or natural).

My question: Why do people assume that when a 'scientist' or group of scientists get together state that Global Warming due to Human's emmissions is FACT. People are convinced and don't challenge their integrity?

Imagine... North America, Europe or Asia (all or each zone on its own), full of trees.... say 2000 years ago. The bio mass... methane, carbon due to wild fires, decay, water vapour... all natural green house gases.... ADD them all up.... you have more if not the same amount of emissions!?!

1970's just when there were "abnormal"
amounts of Solar flares occuring. Many of the same scientists whom think Global warming due to human emmissions is leading to a rise in temperatures, said : The earth was headed for a MINI ice age! (remember that?)
I suppose this is the reason i question the Creditibility of today's scientist.

There you go Dianne. G.

Dana1981... i am sure you have mis read your sources. Mount Plinatubo, philipeans... emitted more CO2, methane and sulfur into the atmosphere than what humans could emmit in two years! Yet the Global temp for that year and the year after fell! You don't need a Ph D... to certify your thoughts.
I think you missed the point.

nickle.... so those who were sure that the CO2 emmissions in the 1970s were NOT enough to heat up the planet... were wrong and scientists today with the same statistics are saying they are right?
Once again... lots of jargon, but not enough insight/experience.
nice try.
You forgot to mention how the oceans are included in the recylcing of the carbon cycle...

ok i like "americaneedstowakeup"s response. Certainly there has been a pattern of increased temps. But... if we could take a step back and look other sources of warming up the planet?
ie/ deforestation.... and the increased amounts of TAR matt (especially around cities) is enough to increase temps.
excess CO2 is certainly being emmitted. however, as far testing goes... scientists HAVE no seen increased amounts of CO2 in the upper atmosphere.... in part.... the oceans have been absorbing much of it.
Global warming theorists cannot, nor have not been able to predict when too much is too much. (How much can the ocean absorb? what threshold or capacity does the oceans have?)

Answer 1

FACTS (Look these up yourself) that I base my opinions on.

- Most of the heat re-radiated by the earth is already absorbed by the atmosphere (95%). Therefore, even if the C02 concentration went way up there is hard a limit as to how much extra heat can be trapped. This limits the worst case heat increase to something much less than catastrophic.

- C02 is a minor heat trapping gas compared to water vapor. Are we going to regulate water vapor?

- Increase in heat of the atmosphere causes more water vapor and C02 to be released by the oceans. So increases in atmospheric C02 are also caused by natural temperature increases not just man made emissions. Separating this out is mathematically impossible without a perfect model of the climate and possibly the whole earth.

- Humans have most certainly added extra C02 to the air.

- Each point raised by Al Gore's movie can be researched and found to have more causes other than just global warming. For example, Lake Chad has been used for too much irrigation.

- People who worry about global warming must assume that the climate is naturally unstable and must project unstable feed back loops to generate catastrophic conditions. If the climate really was so unstable I don't think life would have been able to evolve. It takes too long.

- The climate has large fluctuations on any time scale measurable. It is one of the most complex nonlinear systems imaginable.

Global warming is not what most people think it is.

Global Warming is real. It is partially caused by humans. It will not lead to catastrophes.

Answer 2

You should watch an Inconvenient truth. I also was at first skeptical. I have done a lot of research and the evidence is inarguable. One of my friends is a huge republican but believes strongly that something must be done about global warming. Research shows that when CO2 levels correlate directly with the earths temp. It is also fact that man made CO2 emission rates are very high and increasing drastically, and the total CO2 levels are much higher than ever in the history of the earth. Right now temps are much higher than ever before, way beyond any natural cycle. And glaciers around the world are disappearing and melting. If ice continues to melt in Greenland and Antarctica the ocean could rise 20 ft by the end of the century, and at the current rate the Arctic ice cap will be gone by the year 2050.

Rent "An Inconvenient Truth."
I think it is good that people dont believe whatever scientists say without looking up the facts themselves. So look up the facts and you can see how it is unquestionable that Global Warming is real

Answer 3

You're asking the wrong question. Global warming and global cooling, as well as global just right are all facts. The question is: Do humans cause global warming? The answer to that is NO. No proof so far has been found to show a connection. There's a lot of propaganda and a lot of money behind the hoax. Don't fall for it. Think for yourself. Read on the subject and you'll see through the lies.

Answer 4

I wish I had a chart I once viewed to show you ... but there is a scientific-based chart that shows a time-line with approximate temperatures over thousands and then more recently hundreds of years.. It is really interesting to note that the temperatures were relatively stable up until around 1865 when all of a sudden the temperatures began taking huge and unprecedented leaps. I don't know the basis behind the sudden jump the last 150 years, but I wonder if it was jump-started with coal consumption, etc.? Check some new-site science links ... you may find what I am referring to ...

But all I can say is that it is astounding and pretty scary. The world may not end but if we keep going at the rate we are going, life on this planet will eventually look nothing like it does today.

Answer 5

Global warming sounds like fiction to me.

How can people talk about temperature patterns going back thousands or hundreds of years? From tree circles? From rocks? These people actually expect me to believe that a tree circle or some fossil will accurately show a fraction of a degree change in global temperature?

How can people talk about temperature patterns going back decades? What kind of guages are being used and how accurate are these instruments? Who are taking the readings? Does anybody care about the sources of this information?

If the polar ice caps are melting at "an alarming rate" then why are the sea levels not changing. I live on a coastal city, and I have lived with the high water line for the past 30 years (I'm in my 40s) and there's no difference. How many of you alarmists live with the high tide mark on a daily basis?

My favorite observation is that these "scientists" are trying to convince me that they can predict global weather patterns 30 years into the future! And the funny part is that a lot of people believe this junk! Go ahead and try to convince a commercial fisherman or anybody else whose life depends on accurate weather predictions that you can predict the weather a mere one week in advance.

Answer 6

Global warming has nothing to do with the media, or politics. Its a scientific fact. And that it is being caused by human activities is also a fact. Both thoroughly demonstrated by extensive observations over a period of years.

The ad hoc "explanations" of the "skeptics" simply show their ignorance. Take the "solar flares" --these people are so ignorant of even basic science that they don't even know a)there has been no sustained increase insolar flare activity that correlates with global warming, or b) that it wouldn't matter if there were-solar flares don't have the necessary makeup to cause Earth to warm up.

I suspect the other people at the party were simply annoyed at having their evening spoiled by having to put up with ignorant nonsense.

Answer 7

wow W. that was a long statement...lol...I do believe global warming is real. I was watching this show...and it was showing these people living on the coast (I don't remember the place) the water had come up so far, their home was disintegrating. As all the homes on the coast. They were interviewed...& they fully believed it was from global warming melting the ice caps etc. I know there is so much pro & con on this issue...but I feel global warming is real...I think earth is winding down personally. Look at society...it's crumbling before us.

Answer 8

Yea - Funny how people believe anything that is doom and gloom. I guess the fear of pending doom puts some excitement in their otherwise dull lives.

The Earth's temps are trending upwards, but no one has proven why at this time. If we double the amount of co2 in the air, no one could tell you what the temps would be. It's all just a guess.

Answer 9

HARD FACTS:

So now for the people not believing WE put the CO2 in the atmosphere:

Global atmospheric mass around the earth:
5.148*10^18 kg
=5.148*10^15 t
=5.148*10^12 kt
=5.148*10^9 Mt
=5.148*10^6 Gt
=5,148,000 Gt

Global man-made CO2 (only... it accounts for 70% of all the man-made greenhouse gases):
=24Gt/year

CO2 density=1.98kg/m³
Air density=1.2Kg/m³
Ratio: the CO2 density is around 1.6x the density of air.
This means that for the same weight, CO2 has 1,6 times less molecules (parts)

Now what is the rate we increase CO2 in the atmosphere for sure (counted land use change/deforestation/use of fossil fuels, etc...):

5,148,000 / (24/1.6)=2.9*10^(-6)

Considered in PPM (parts per million) 1 million=10^6

change in PPM = 2.9 * 10^(-6) * 10^(6)
2.9 PPM (per year)

So during the average 1997-2017 period we should increase the PPM concentration by 29PPM

Now look at the measurements:

http://en.wikipedia.org/wiki/image:mauna...

We see an increase of close to 20PPM in the last decade...

THIS IS TOTALLY CONSISTENT WITH MY CALCULATION PUTTING THE MAN MADE CO2 AS CAUSE FOR THE INCREASE IN THE EARTH ATMOSPHERE

first, READ these articles

I've chosen mainly American sites, but they say the same all around the world.

second, FACT: this year is the first time in recorded history that TWO category five storms have made landfall in the Atlantic region.

the 5 hottest years ever recorded in Europe have all taken place within the last 15 years

two of the Antarctic's ice shelves "Larson B and Wilkins" lost as of 1999 over 3000 square kilometres of their total mass.
that's like a freaking country... ...poof, gone...

it's cool that you are finally asking this question, at least you are willing to test the water.
