Global Warmists back off on prediction

The second guess makes a lot of sense. The chemicals and CO2 is usually not the main factor (until recently maybe???), but a catalyst that has made the main factor much stonger.

Are you saying its a synergistic reaction whereby the gases we emit are exponentially affecting the natural variances?

[piercehawkeye45]

I used catalyst as a simile.

If the gases increase the effects of the natural rise in temperatures then the gases can be related to catalyst by making the final product much stronger than what would have happened naturally.

The differences is that a catalyst usually speeds up a reaction instead of strengthening it and a catalyst has no effect on the actual reaction while the gases will have an effect.

From Pond Scum To The Jet Tank
BusinessWeek 08/13/2007
Boeing (BA ) has teamed up with a handful of airlines to figure out how to make a jet engine that's efficient and environmentally friendly. Among the candidates for the biofuel that will power this engine: algae.

Turns out the green gunk that coats stagnant ponds and unkempt aquariums offers advantages over other efficient fuels, such as ethanol made from corn. Algae-based fuels may hold up better in the extreme temperatures, pressures, and weather conditions at which jets operate. What's more, algae is abundant and grows naturally, which should make it cheaper to harvest than crop-based fuels. Boeing is working on the project with New Zealand-based Aquaflow Bionomic and Air New Zealand.

Separately, Boeing is testing other types of biofuel with Virgin Atlantic Airways in an effort to convert an engine to run on clean fuel by 2008. A spokesman says one promising candidate is babassu, a Brazilian fruit similar to the coconut.

Oh and
CO2 is niet de grote boosdoener bij de klimaatverandering en de opwarming van de aarde. Dat is de conclusie van een groot wetenschappelijk onderzoek van het KMI dat deze zomer nog wordt gepubliceerd.

It's a least another piece of the puzzle. I doubt like hell there is one lone answer to the climate's future.

And forget the second link, they aren't even smart enough to speak English.

Dare I say, Bruce, that you'll get in Dutch?

Secretary of the Air Force Michael Wynne announces in front of a B-52H¸ at Edwards Air Force Base¸ that the B-52H is now certified to fly a blended synthetic fuel. [U.S. Air Force photo]Secretary of the U.S. Air Force Michael W. Wynne, Aug. 8, announced the completion of the Air Force’s certification of Fischer-Tropsch fuel blends for the B-52H during a signing ceremony at Edwards Air Force Base, Calif.

Wynne signed a certificate at the ceremony certifying that a blended FT and standard JP-8 jet fuel is safe for operational use in all B-52H aircraft.
"This is a great day for the U.S. Air Force, it’s a great day to be here at the flight test center, and it’s another milestone achievement that’s been accomplished at the flight test center," said Wynne.

The B-52H was chosen as the test platform because of key advantages such as its eight engines, he said. The fuel system in the B-52 can simultaneously isolate, carry and manage both a test fuel and the standard JP-8 fuel.

The Air Force now plans to test and certify every airframe to fly on a domestically-produced synthetic fuel blend by early 2011.

Heh, often when I see "synthetic", I think "made from petroleum". What is synthetic jet fuel synthesized from?

[xoxoxoBruce]

The Fischer-Tropsch process is a catalyzed chemical reaction in which carbon monoxide and hydrogen are converted into liquid hydrocarbons of various forms. Typical catalysts used are based on iron and cobalt. The principal purpose of this process is to produce a synthetic petroleum substitute, typically from coal or natural gas, for use as synthetic lubrication oil or as synthetic fuel.

edit
I would think they will certify others, like the pond scum fuel, as they become available.

I read that as "catalyst as a smilie" and I was thinking...where's that smilie, never saw that one? [/unrelated levity]

No Arctic ice cap by the summer of 2030?

Experts say they are "stunned" by the loss of ice, with an area almost twice as big as the UK disappearing in the last week alone.

[xoxoxoBruce]

Good, it'll make it harder for the terrorists to come over the pole and easier to get at the Arctic oil reserves for our Hummers.

[HungLikeJesus]

Bruce, did you mean to post that here, or in the Sexually Ambiguous Words thread?

[Griff]

...pretty expensive hummer

A decade later, how have our views on Global Warming shifted? A decade is an insignificant blip on any meaningful data set, but how have the intervening years of "muddy the waters" versus "nails in the coffin" science/news influenced us all?

Would it have mattered if we'd known that Exxon has known about human-caused climate change since 1977?
