Global Warming Experiment #1

(I slightly changed the instructable into a forum topic and an instructable)

The Instructable Half

"Global Warming" Experiment #1:
As you can tell by my quotes around "Global Warming", I personally don't believe that this theory is happening. Theres facts I can use to prove this. However, even I believe that no matter how you put it, there's going to be some bias. Also facts are boring :P

So, what I have planned, is to do a series of experiments on what global warming might cause if it were real.

I'm doing this because I've heard people claim some extraordinary things, which based on data won't happen.

I could post an instructable with a bunch of facts, and I might. But for now, I want to set up a couple collaborative experiments. One reason I want collaboration is I'm biased. The other, is so you can't complain about my methods.

I haven't done the experiment yet, I really don't know if this will help, or hurt, my case.

The experiment is to determine if "global warming" could melt glaciers, thus cooling the ocean. Notice here I'm assuming global warming is happening. It isn't. But when people make claims on the news and stuff, they are assuming that too.

Please comment if you would like to change my methodology, OR you want to do the experiment.

I'm going to describe how the Instructable (and hopefully the rest in the series) will work.

1) I, or anyone, proposes a framework for an experiments and writes up an Instructable. (Will be referred to as "I" in the following steps)
2) I monitor the suggestions, editing and fixing as needed. After about a week or so, I go onto step 3.
3) I preform the experiment to the best of my ability, and write up an additional 2 steps.
3a) The first outlines my changes. This could mean I didn't have a 4x8 loaf pan, and I had to use a 3x8. Or it was plastic. Whatever. These small details are important
3b) The second outlines the data and conclusion. This may have images of the experiment, graphs, tables, sensor data, Whatever. I also make a note of my previous bias.
4) Wait for more people to run through the experiment, adding them as collaborators.
5) Write up a conclusion to everything, OR do some more investigating.

Its not that bad, however the whole process might take a few weeks. (I don't know)

Scientific Method
There are seven steps to the Scientific Method, which we will follow:

1. Define the question
2. Gather information and resources
3. Form hypothesis
4. Perform experiment and collect data
5. Analyze data
6. Interpret data and draw conclusions that serve as a starting point for new hypotheses
7. Publish results

(Thanks Wikipedia!)

#1 was done in the introduction.
#2 I've already done, however you only have to look into data you'll need during the procedure.
#3 I've done it, but I'm not telling you (I don't want a bias, even though I've hinted towards my guess)
#4 - We're going to expand this out. More later!
#5 and #6 sort of come together in this format, will be done as we go along.
#7 is done as we go!

Okay, #4. Remember back to High School, remember Lab Reports? Well basically there will be a step for each segments (leaving some out). We sort of do this already in most instructables "What will happen", "What you need", "How you do it"; this time more formally. Due to Lab Reports being unstandardized, I'm breaking it down into:


Its shorter than your average one, due to the fact in Data, you have hypothesis and stuff I don't want to reveal yet ;-)

The following is the framework, you can also see my instructable:

(This is a framework, remember. Its not supposed to be "done" and perfect)


*Large basin of some sorts.
*Lamp + Light bulbs (100W & 40W)

1) Fill large basin/pan with water.
2) Take and record standing temperature of water.
3) Add ice off to one side of the pan.
4) Take temp. of water every five minutes until it starts to level out, at least 4 readings.
5) Replace water, and repeat steps 2&3
6) Shine lamp w/ 40W bulb off to the non-ice side of the pan, but allowing some light & warmth to reach the ice. (Roughly 20-35%)
7) Repeat steps 4&5
8) Repeat step 6 with a 100W bulb

Take pictures throughout!

What now?
Okay, I'll be updating this with your comments over the next week or so. If somethings wrong with it, POINT IT OUT!!! I'm going to add my thoughts in as well. (I still feel its missing some things, I can't put my fingers on them, though!)

Melting of glaciers does not 'thus cool the ocean' it makes the sea level rise the oceans heat up due to absorbed energy redirected from the earth's atmosphere because of the particles the heat of the ocean is what causes the glaciers to melt to say that melting of glaciers cools the ocean shows you have no knowledge on just the beginning of the science of global warming.

Umm... It's a lot more complex than that.

Firstly, the author didn't say "melting glaciers cool oceans", he said "do melting glaciers cool oceans?", a very valid question.

Secondly, sea-ice melted in at least three ways, to varying degrees; from below, by the warmer
oceans; from above, by the warmer atmosphere; from without - particulate
deposits from air pollution darken the surface of the ice and make it
absorb more heat directly from the Sun.

Melting sea-ice does nothing to sea levels. The melting of land-ice does cause a change
in sea levels, but the main issue is salinity - melting sea-ice dilutes
the oceans, and the resultant changes in density are expected to play
havoc with the various ocean conveyors that currently distribute heat
around the planet - for instance, the shut-down of the Gulf Stream would
dramatically reduce the temperature in Western Europe.

i dont understand i need help

Global warming is a hoax.
And your evidence is...?
science classes Ive taken, ive looked at several charts on temp changes spanning over the 1900's it only changed about 1/2 a degree, also people are worried about the hole in the ozone layer... which is over Antarctica. If it does exist i don't see it as a large problem.
Firstly, the temperature rise has been twice that level. Secondly, have you any idea how much energy it takes to increase the temperature of an entire biosphere by so much, so quickly?   A quick back-of-the-monitor calculation puts it at around 6,000,000,000,000,000,000,000J - hardly an insignificant amount.

Plus, it is a little odd that your teacher restricted the data he gave you to just the last century. Where in the world are you? Texas?

Try this from Berkley (see also, and also the original report)

As for "if" the hole in the ozone layer is real, it's over more than just Antarctica, it is the cause of Australia's huge skin-cancer issues. It is also no longer restricted to Southern latitudes. There's one over the North Pole now, and its effects extend well over the North American continental plate. There is no "if" here - both holes are very real, and have been shown to be due to chemicals released by humans.
1 degree whoopee...

Ok i'll admit i didn't know that it was effecting Australia, and was it CFC that they tracked it to?

I do not live in Texas and i am homeschooling.
Your sarcasm shows you don't understand the scale of the issue. Six sextillion joules of energy is the energy of a dinosaur-killing meteorite.

Yes, it was (amongst other chemicals) CFCs that caused the hole - the chemical process is quite well understood now.

Check the links posted at 12:20 above, and then ask yourself why your sources downplay the problem so much.

I must look into this.
