Is Global Warming happening?

[Booko]

Couldn't this be a coincidence, have we even been recording temperatures since before the industrial revolution? The timeline of your graph isn't even .01% of the Earth's umm..."lifespan" (for lack of a better term). How do you explain the ice age? Who caused that?

We can tell temperatures for about 300,000 years back by looking at ice cores to see what sort of plant material shows up. That area of science has been well established for quite a while.

Ice ages are caused by slight variations in the Earth's orbit. There are times when we're farther from the sun, and that's when an ice age happens.

Increased "grey" volcanic eruptions can cause shorter term cooling periods, but nothing on the scale of hundreds of years.

(I remember the summer after Mt. St. Helens blew. We were on honeymoon in Wales and central UK and we never saw a sunny day and it was about 60F...in July.)

Anyway, I digress -- another well known cycle is the cycle of solar activity, which runs 22 years. There are short term warmups on account of this cyclical pattern of solar energy output, but again, nothing that would account for a warming trend that just "happens" to coincide nicely with rising CO2 levels and the Industrial Revolution.

There's even more than this, but this on its own answers the question of "coincidence" and the answer is, "No, it ain't."

As I mentioned in an earlier post, the scientific community has been looking at this since at least the 50s, with increasing interest as the data came in and was not found wanting.

There is now dispute among climatologists that global warming is happening and that we are at responsible for it.

The disputes are more about specifics of mechanisms, regional effects, and so forth.

Claiming there is no consensus in the scientific community about global warming is saying there's no consensus about evolution.

The few people left who dispute this are not those qualified to speak on the subject.

I wouldn't consult a lawyer if I need an appendectomy. I'd see a doctor. And if I want to find out about global warming, I'd ask a climatologist, not a political hack.

Like someone stated much earlier in this thread, a single volcanic eruption causes the release of more greenhouse gasses into the atmosphere then we'll ever produce.

Someone may have said that, but I dispute its accuracy.

So I guess the ozone layer holes and depletions should be attributed to natural causes too which, probably in your opinion, has nothing to do with a steady rise in earth's mean temperature ???....

Actually, FFH, I haven't read much about a relationship between the ozone layer and global warming.

CFCs prevent re-creation of ozone (it's not a very stable gas), which would cause enlargement of the ozone hole.

But that's unrelated to CO2 or SO2 levels, as far as I know.

Dude, did you read my previous post. It's not about what you think to be true, it is about what you can PROVE!!! Even if the depleted areas of ozen contribute to an increase in the earth's median temperature, there is no proof that man caused the depletion in the first place. Try again.

You're right about the ozone layer, Buddy.

Unfortunately, any link with global warming is tenuous at best.

Since ozone depletion is not one of the mechanisms involved, the point is kinda moot for the purposes of this thread.

Or you want it to be fake just so that you yourself can take your mind off of the problem. It's real.

I don't know if I can believe that. Sure, a volcanic eruption does throw gases into the atmosphere, but remember, the eruptions don't last for all that long, and they aren't all that frequent either.

As for global warming, I have reason to believe it isn't taking place.

We recently had icebergs float right up past Dunedin, New Zealand, from antarctica. Now if it was supposed to be warming up, wouldn't they have melted before they got there?

 

[Booko]

Yeah. You gather observable, empirical, and MEASURABLE evidence, that is SUBJECT TO THE PRINCIPLES OF REASONING. In the world of the "man attributed" global warming theory, there is not enough historical measurable data to conclude that man has such an effect. So consensus among scientists is substituted. This is not accepted or even practiced and you will not find it in the Scientific Method.

I misspoke in an earlier post and went and rechecked my facts about how far back ice cores are considered reliable. I was off by a factor of 2. My bad.

So...are you saying that 600,000 years of data is not sufficient for you?

There are less direct methods that range back million of years, btw. That isn't long enough to have some idea that this current trend is abnormal?

No one was there to measure temperatures in the Pliocene, but we know it was hot and dry all the same.

Saying that "we can't tell" because no one was there with a thermometer prior to the 1800s is missing the point, to say the least.

And besides, funny thing is, the ozone hole is in the southern hemisphere, while most greenhouse gasses that are released are in the northern hemisphere. As far as I'm aware, northern hemisphere air cycles around the northern hemisphere, and the southern hemisphere air cycles around the southern hemisphere. There isn't all that much mixing in between.

all i know is Canada is finally warming up a bit and for that I praise the lord

While to me it feels as though it's getting colder. I remember not being able to sleep suring summer without all my windows open and a fan going. Now I have all the windows closed and no fan.

Could there be a difference in hemispheres?

Some people in my area reckon the seasons have moved by a few weeks. And it feels that way to me. It feels as though summer doesn't really start until new-years, and as a kid I remember full-blown summer before christmas

The depletion of the ozone layer is still happening, it would just be a matter of observing the effects of CO2 and CO on the particles that make up the ozone.

It's a simple question and a simple experiment...

Does CO2 and/or CO bond with the particles that make up the ozone layer and cause these particles to no longer be able to do their job, which is to filter out the specific rays of the sun that are harmful ???

I'm sure this type of experiment or something similar to it has been done but the results have been hidden or not widely published so as not to hurt the precious car or oil industry...

We are at the mercy of these industries and can do little to stop the trend,,,,

I use a mixture of 2 parts gas to 1 part ethanol (basically corn husks) to run my bike to work and back and would use straight ethanol if it could handle it, which it can't of course for it tends to melt anything that is rubber or plastic

If you have a newer car you should be using straight ethanol (see your owners manual)

Most new cars can handle straight ethanol but people don't even bother to find out where the nearest station is...

I don't. I don't want to know what overall effect our melting glaciers is going to have on our ecosphere because I doubt somehow that it'll be good.
