What is the so called "evidence" for global warming?

Question

No wikipedia links, tis blocked :)
I know global warming is nonsense but i need all the help i can get for my case study.

Answer 1

well, "global warming" is not nonsense. the temperature of the earth is rising, and the ice caps are melting; whether or not we are accelerating it is your hangup, no doubt.

Answer 2

Here is an example of selective reporting. Attached is a link to the charts the from the UKmetoffice that many people cite as proof of the influence of man. Look at Q2.2 and notice the two charts below. The charts shows their projections in green and the acutal observations in red. The top chart shows their projections taking only solar and vocanic influence into account. The bottom chart shows their projection with solar, volcanic and man made influence.

Here is their claim regarding these charts found below them:

“…most of the observed warming over the pas 50 years is likely to have been due to the increase in greenhouse gas concentrations”.

Now if you look at the last fifty years(1950-2000) on the chart, the green projection does seem to fit closer to the actual observations. On this they hang their collective hat. Yet, if you look at the previous fifty years (1900-1950) their model is about 50% accurate. If you look at the first fifty years (1850-1900) they are not even close.

These charts clearly show that their projections are wrong more than half the time. Why should we be expectd to accept only the last 50 years as proof? Besides, how they quantify which phenomion, solar, volcanic or man is not clear. Also, their projection shows the least change occuring duing the highest era of industrialization and pollution.

So in all honesty, these charts display a projection of a possible explaination for a temperature increse of less than one degree in over 150 years. What we are not being shown, is these temperature observations back a previous 150 years. Well, if you could see that part of the chart, it would look very much like this part of the chart. What you are looking at is simply a segment of a much longer chart that displays a steady and consistant rise and fall cycle of temperature.

There is noting of substance in this chart. It is deliberatly being presented in a way to mislead you about what it is showing. The earth's temperature swings back and forth plus or minus about a half a degree over a hundred and fifty years. So, what? Where is the rest of the chart, the previous 150 years?

This my friends is not scientific proof. It is deliberate scientific deception. No wonder the GW zealots want to shut down debate and silence the skeptics. They cannot withstand an assault on their house of cards.

If you have truth on your side, you do not seek to silence opposition. You readily invite debate. You readily engage in the defense of your claims because there is nothing to hide. On the other hand, if you have been deceptive in your presentation you will have to avoid debate at all costs. You will have to silence the opposition before they expose you. Now ask yourself, which side is trying to silence the other?

Merry Christmas!

Answer 3

Charles Keeling, the 450 ppm threshold and CO2 concentrations over the last 40 years. By examining ice core samples chemical and oxygen content they have discovered over the entire geologic history of the earth at no other time have CO2 concentrations risen this quickly and to this level. The shifting of habitat ranges for all species, thermal expansion of the ocean, ocean current changes, reduced crop yields and snow pack. You should read the International Panel on Climate Change Report they have an executive summary for law makers that is easier to read of you are not scientifically inclined

Answer 4

It's warming up , but it's a natural cycle. There were grape vines growing in York (north-east England) in Roman times.
90% of Greenhouse gasses is water vapour, 5% Methane and 5% the dreaded CO2. Of this 5% we as humans produce 10%. So in effect we only produce 0.5% of greenhouse gasses.

It's just a way for government to enable a Weapon of Mass Taxation.

Answer 5

The evidence that global warming is occuring is based on our ocean temperature data and surface temperature data from around the world. This information dates back to the late 19th century. Since there can be internal variations in our climate, any given warming isn't necessarily a trend. We could literally have no changes in our sun, human, or other forcings and still have variations in our climate because it has some inherent randomness in it (it is chaotic). For this reason, statistical analyses are performed on the temperature data (after extensive checks for systematic errors and anomalies in the record). From statistical analyses, there is now determined to be a 99% chance that there is a warming trend (trend meaning not a random fluctuation). Some non-temperature data evidence includes dramatic decreases in the extents of alpine glaciers, sea level rise, early ice-break up in lakes around the world, and decreases in sea ice.

Answer 6

There are many questions asked on here about global warming. There will be plenty of stuff for a case study if you search Yahoo Answers

Answer 7

Polar ice caps are melting at an alarming rate. Satellite imagery that compares the size of the polar ice caps from years past show they R shrinking in size. Sea levels are rising as the ice melts, global weather patterns are becoming more violent as this cold water impacts the natural currents of warm and cold water. This year in the US has been reported as one of the hottest in over 130 yrs. It is definitely NOT nonsense.

Answer 8

Try to think of it a different way.
If the environmentalists are right and we follow their advice we have a better earth, clear of dangerous and noxious substances and have saved the planet for future generations. If they are wrong and we follow their advice, we still have increased research into more efficient technologies. This leads to less reliance on oil and gas which means no rising prices for consumers because we become less reliant on these fuels as they run out (still not bad).
If the non warming political lobby is right and we follow their advice. In the short tem no change until oil and gas hit critical levels at this point fuel and heating rocket in price. The next stage is a rush for alternate technologies which have had stunted growth and are now not at full efficiency and expensive to buy. If they are wrong! The polar ice caps melt. This happened once before in earth’s history, now the politicians have you believe that water levels rise, weather becomes harsh and life unpleasant. What happened last time was the ocean currents stopped this deoxygenated the oceans. Next all marine life dies and rots. This causes massive eruptions of noxious gas from the sea (don’t remember the name it was hydro something) which in turn deoxygenates the air and the land animals die. Last time 99.5% of all life on earth perished.

Now given weather global warming is happening or not I would rather be with the environmentalists and be wrong wouldn’t you.

Dying rich whats the point.

Answer 9

definite it has grow to be a faith and Al Gore is the pope of the cult.think of of how lots money specific communities will make off of the hype.think of of all that government money going to "examine".as nicely there is basically lots you're able to do ,inspite of each little thing whoever controls the climate controls the international.worry is the superb political motivator. climate replace is a element of the character of the planet.straightforward experience is to have sparkling capability yet till there's a greenback in all of it that happens is communicate,communicate and extra communicate.government policies,fines and outcomes(gotta get that bailout money someplace) We easily choose sparkling air and water .i'm the unique recycler and that i don't waste capability in simple terms like many human beings.i take advantage of capability and don't choose for the "guilt" holiday of doing so. I actually have a concern with Gore the guru who flies around a gas guzzling jet.So does Queen Pelosi who opted for an even bigger one to fly returned and forth to California.bear in mind her announcing she desires to keep the planet,yeah she flies we walk.we can all commence via using the recent capability saving easy bulbs. Oh I forgot they are those with mercury in them.Oh,nicely looks like a superb thought on the time. i assume you all heard that some genius baby-kisser needed to tax cow farmers for any that very own extra desirable than a hundred for emitting "methane gas" yeah it is actual.can we bottle it extremely?Or on 2nd concept deliver some from the bull to that baby-kisser as he knows the B.S. whilst he sees or smells it.

Answer 10

Global temperatures are rising. FACT!

The cause is where the debate is. There is a immense and growing scientific consensus that it is due to human activity, principally the artificial release of "greenhouse gasses". On the other hand there are those, mainly Republican Americans that deny the existance of a problem because GWB and his oil buddies don't like it.

It was good to see the USA indicate a desire to positively engage this critical issue in Bali recently. Congress are sidelining Bush and his irrational denial.

In any event, by the closed mind tone of your question, we're banging our heads aginst the wall with you anyway.

Answer 11

Some of the ice is melting because there is a fissure in the earth's crust that is rather thin. The magma and lava at the earth's core is closer to the surface, because of the fissure, and melting some of the ice. Polar ice caps are increasing in some areas.
