Debate time: Global Warming

[wednesday]

ok..but dont say i didnt warn you...ohhh n defo over the cower

I

Hope that I am wrong. Even though, when I look at the science, the facts, I know that I am right.

Some people have their own pre-conceived idea that it just cannot be happening and will come up with all sorts of arguments to defend themselves and keep their head-in-the-sand policy because they're just too afraid to face the truth:

This is our fault, and if we leave it with nothing done, we will have to face the consequences.

We can't blame it on nature or the sun, we have to take responsibility for our previous mistakes.

The risks are to high, the consequences to serious.



Things like these diminish my hope and lead me to believe that our very human nature will sink us to the bottom.

Things like this give me hope that we will pull through on top.

Re: I

why are we starting another thread on this? Im merging them

Ignorance is bliss for some.

Therefore we are our own demise in this world unfortunately.

There are some things you can't ignore.

See that there just proves you do not have an open mind and had no intent to debate. You will make a good democrat and enviro nut with thought processes that closed if you keep thinking like this.

because she likes the attention.

 

[AUDRAA]

Dana be nice.

 

[Dana]

I am... I didn't call her names

 

[Goat Whisperer]

Dana, go away.

You did too! I saw it before you deleted it.

 

[Maulds]

OK I am politely asking questions here, don't bite my head off.

Why is CO2 blamed for the heating?

I quoted myself...thats shameless

 

[Goat Whisperer]

Because of the green house effect. CO2 is a green house gas -> we are adding to it -> green house gasses block in long-wave radiation, that warm the earth -> therefore, because of the increase in CO2 we are increasing the temperature.

 

[Maulds]

But weren't CO2 levels much higher in times past? Seems like I read somewhere that they've been as much as 12 times higher in the past than now. Why wasnt there catastrophic climate change then?

 

[Goat Whisperer]

First off, you don't have a source, so probably not and that was just a poor skeptic argument someone made up. Especially since I can't find anything about it--not even on the skeptic sites.

Secondly, you might have been referring to the beginning of time when all gasses were out of whack. And to that I'd say *probably* but that was extreme nature, obviously much different then today.

Until you give a source, I really can't come up with more.

 

[Maulds]

I'm gonna Google til I find something that matches what I said because I know I saw it somewhere.


edit: Wait a minute, what if I find the source...does that mean you just discredit the source instead? I'll find it for you, gimme a few.

 

[Goat Whisperer]

I like to debate on science not words, if you give me the thesis I'll give you a fair rebuttal to the science.

 

[Maulds]

from heartland.org:



Carbon Dioxide is such a small component of Earth's atmosphere (380 ppmv) that the "slice" it represents in this chart is really only a "line" about 1/2 as thick as the line shown. Compared to former geologic times, Earth's atmosphere is "CO2 impoverished."​

​

In the last 600 million years of Earth's history only the Carboniferous Period and our present age, the Quaternary Period, have
witnessed CO2 levels less than 400 ppm, except during periods of glacial expansion during ice ages.

​

Late Carboniferous to Early Permian time (315 mya -- 270 mya) is the only time period in the last 600 million years when both atmospheric CO2 and temperatures were as low as they are today (Quaternary Period).
Temperature after C.R. Scotese Climate History
CO2 after R.A. Berner, 2001 (GEOCARB III)
There has historically been much more CO2 in our atmosphere than exists today. For example:
During the Jurassic Period (200 mya), average CO2 concentrations were about 1800 ppm or about 4.7 times higher than today.
The highest concentrations of CO2 during all of the Paleozoic Era occurred during the Cambrian Period, nearly 7000 ppm -- about 18 times higher than today.
The Carboniferous Period and the Ordovician Period were the only geological periods during the Paleozoic Era when global temperatures were as low as they are today. To the consternation of global warming proponents, the Late Ordovician Period was also an Ice Age while at the same time CO2 concentrations then were nearly 12 times higher than today -- 4400 ppm.
According to greenhouse theory, Earth should have been exceedingly hot. Instead, global temperatures were no warmer than today. Clearly, other factors besides atmospheric carbon influence Earth temperatures and global warming.










Now don't be hateful, this is the kinda thing you've been begging for.
