Study blames humans for weather change
Posted by Michael Scott September 17, 2007 17:24PM

A national scientific study released today says that human beings are to blame for increased moisture over the Earth's oceans.

A global increase in moisture will likely lead to an increase in overall temperature, scientists say, and will likely affect us in the Great Lakes region.

Atmospheric scientist Ben Santer of Lawrence Livermore National Laboratory, the primary author of the paper published by the National Academy of Sciences and released at 5 p.m. today, said in a telephone interview that the report does two things:

* It identifies a distinct human impact on ocean atmospheric moisture over a 19-year period by revealing that 22 different world climate models cannot account for the overall increase apart from our influence...

3. The fact that water is the #1 greenhouse gas is touted by the deniers....
...but as usual, they're disseminating.

An increase in atmospheric H20 is an expected feedback to increases in C02.

It's understood and predicted by scientists.

Decrease the C02, and the H20 drops.

5. Also, H2O has a much shorter halflife in the atmosphere, on the order of weeks
CO2 is something like 200 years.

9. the Colorado river ends up in the atmosphere
same for the Nile, etc

unlike how it used to be.

sure, the water drops out in a week or month.
but the process is unendingly replenished

4. I'm not a believer or a denier
the jury is still out with me when it comes to global warming. Last night there was a great program on the History channel called "how the earth was made". After watching that two hour program it really hit me, we are just along for the ride.

8. Well there's no doubt the earth
has been warming since the end of the last ice age.

I also don't think there's any doubt that humans have sped up the process.

The question is what happens next?

I just finished "The World Without Us." which looked at what would happen to the world if all the humans just up and left one day. Interesting though not particularly well written IMO.

11. How the seasonal variations in CO2 concentration create the seasons
Well, first of all you have to forget all that stuff about the spinning Earth being tilted at an angle of twenty-something degrees to the ecliptic, and cooling during its Northern winters, warming during its summers. Forget about the Sun. Or better still, think of the Earth as being flat.

Think instead about CO2 in the atmosphere. During summer, when plant photosynthesis is maximum, plants absorb CO2 from the atmosphere, and reduce its levels, and thus reduce global warming, resulting in a subsequent cold winter. During winter, when plant photosynthesis is at a minimum, CO2 levels tend to rise, resulting in global warming - and the subsequent warm summer.

See. Quite easy to explain.

You’ll probably want to know about anthropogenic seasonal variation too. That is, how humans manage to create the seasons. And this happens because, during winter, humans tend to light fires to keep warm, and these fires generate CO2, which causes global warming, and results in warm summers. During these warm summers, humans stop burning fires, and the excess CO2 is absorbed by plants, reducing atmospheric CO2 concentrations, and bringing global cooling, and the subsequent winter.

The result, as I’m sure you’ll see, is that the seasonal cycle of spring-summer-autumn-winter is entirely created by human activity, and if humans would simply stop burning fires in winter, this seasonal variation would vanish, and terrestrial surface temperatures would remain more or less constant.

Convinced? I’m sure you are. If you want to save the world from the endless cycle of the destruction of the creation, all you have to do is to not turn on your heating system when temperatures fall 10 or 20 degrees C below zero. It would also help if you stayed outside, and didn’t wear any clothes, or ate anything. You know by now that it makes no sense to do stupid things like that, right?

12. That analogy is unconvincing....
The self-proclaimed skeptics on global warming have yet to give a good explanation for the dramatic rise in the average global temperature, one with the kind of solid evidence that human-caused AGW has acquired. They told us that it's solar forcing, cosmic rays, or this mysterious and apparently unknown "climate cycle", which is never explained (we know about the effects of cycles like the . Solar forcing is already accounted for in the models of those who see human-caused AGW as the culprit. The cosmic ray connection theory has holes in it, as well (http://news.bbc.co.uk/2/hi/uk_news/6290228.stm). So now many of the climate change contrarians are saying that it's just a natural cycle. Well, what cycle are they talking about exactly? The precession of the earth, for example? That's also been taken into consideration.
