Another global climate docu: CBC - Global Warming Doomsday Called Off

[MelchyBeau]

Nielso,

This isn't hey lets make hasty generalizations forum. You often attack sources yourself. You often reject anything any governmental organization says. Yet you critique someone for attacking the sources for this documentary.

You choose to ignore any arguements by using the box method. Leave that to BBV.

there will be no exchange of information between you and other people on this board because you simply choose to ignore anything anybody says that doesn't fit your worldview.

Why don't you dig up some papers from the 1970s as well that support your "theories". I am sure they will be well recieved

So he's saying that based on what he heard from the natives, that tree was in the exact same precarious position for 50 years, and since it hasn't fallen over completely, that's proof that the sea level isn't rising (since waves would accompany that).

Did I get that straight?

Ohhh the irony..

[Nielsio]

It would be helpful if someone who actually supports that stuff, to provide the 'new and improved' ipcc arguments/evidence.

Simply saying "I heard of someone claiming he has arguments that aren't addressed here" is not very helpful.

To add a bit more meat to this discussion:

- In the video they attack the "hockey stick" graph of warming that was a key feature of the 2001 report they criticize. Given that the video was aired in 2004 and probably produced in 2003, all concerned would have been unaware of the findings of later comprehensive reviews by the Senate and National Academy of Sciences, which affirm the hockey stick, although with larger error margins.

- 2005 was the hottest year on record, hotter than 1998, with 2002,2003 and 2006 behind that, and the hockey stick continues to climb, further affirming the trend. See:

http://www.nasa.gov/centers/goddard/...2006_warm.html

- The video claims that temperature measurements are affected by the heat of buildings, roads, etc. The report specifically investigated this and found:

Urban heat island effects were determined to have negligible influence (less than 0.0006 °C per decade over land and zero over oceans) on these measurements.

The urban heat island is kind of specious anyway, since ocean data shows exactly the same trend as land data. You can see that on the NASA site. So WTF are they talking about?

- Even global warming deniers now generally agree that the earth has warmed beyond a doubt, given the data from 2001 to now. This is one of the very things they attack in the video, claiming that it's due to "heat island effects" caused by buildings and concrete. Just about no one gives any credence to that claim - the warming is real, whether it's human caused or not. See what I mean about the video being out of date?

Anyway, I suggest you read the IPCC report for yourself (I would bet my life that you never have), instead of spending your time on outdated pop culture docutainment. There's real science here if you care to look at it.

Now THAT was an ad hominem

Hi Phil

Given that there is a warming trend, which I thought most scientists agree was occuring, and given that it could be caused by green house gasses such as water vapor, what exactly are we supposed to do about it? Drain the oceans?

[Phil153]

Evaporation is a function of temperature. Something else has to cause the system to get hotter first; water doesn't spontaneously begin evaporating more to cause the planet to get hotter.

The only things that can really do that are fluctuations in long lived gasses which cause warming (such as CO2 and methane), changes in solar output, things like cosmic rays affecting cloud formation, and possibly local effects such as reflective changes in a particular region. The world's scientists are conservatively more than 90% certain (in the sense of statistical error) that greenhouse gasses are the main cause in the warming we see, and that they will continue to drive warming into the future. Take that for what you will.

What we need, as wacki says, is alternative energy sources, and quickly. An energy Manhattan Project would be a good start that would also reap enormous benefits for the economy, security and technological development. There's really no reason not to do it.

[Zeno]

The world's oceans are a large heat sink and help moderate local weather and long-term climate. Draining them would be an interesting experiment but would only exacerbate the present situation.

[Arp220]

If you want to get all scientific about it, CO2 amplifies an initial climatic forcing.

And that video is laughable.
