ok, let's go back 1000 years and then look at some model results. (graph in the middle of the page, the IPCC site is slow at the moment)
In the grand scale of the Earth the observations just a century so of data might as well be one days data.
True, but on the grand scale of me, or a city, or a civilization, 140 years is quite a long time. And applying theories to data (and data to theories) is what science is all about). If you're doing historical science you can make a prediction about what you expect to see in data obtained from the past. Do you not believe in geology?
here's some "empirical evidence of global warming":

Actually, the current record for "most powerful camera" around mars goes to Mars Global Surveyor's Mars Orbital Camera, launched in 1996, which itself was a duplicate of an instrument on the failed Mars Observer (1993).
Morph was definitely in use in computer animation circles pre 1993. It made big splash in Michael Jackson's "Black or White" video in November 1991. I'm sure the term was in use before then.
in principle I agree about embargoing data to fit a scheduled press release, but on the other hand NASA would be justifiably upset if a major newspaper or network ran a mars image and gave credit to a hobbyist. (I've seen the AP, Reuters, and AFP frequently get credit for NASA images)
it may also be an issue of infrastructure--archiving and distributing scientific data is non-trivial. you want to make sure all the data packets have been received, ensure data integrity, make sure the medata is connected to the right file, etc. etc.
keep in mind that everyone even remotely involved with Mars at JPL is completely overworked at this point. outreach people have been pulled from other projects, and I suspect botht the scientists and PAO can't get out as much as they would like to.
It's not emitting much of anything near visible wavelengths, since the temperature maxes at about 5 degrees C. (for significant emissions you need to be in the thermal infrared (measued by the Mini-Thermal Emission Spectrometer, not the pan camera). The pan camera is seeing reflected light.
I would guess (based on my experience with other NASA data archives) that the full scientific data are not being released until they've been calibrated, at which point they'll probably end up in the Planetary Data System It's also possible that the Principle Investigators (who are affiliated with Cornell, not NASA) have exclusive use of the data for some period of time. Scientists are often very reluctant to share data until they're happy with it. Whether this is good public policy (since the data was all paid for by the US public) or good science is open to debate, but it's certainly not a conspiracy.
In the case of the more dramatic images, Public Affairs is almost certainly embargoing the images so the press release will (in theory) have more impact. If you really want the data you can always try a Freedom of Information Act request.
It just means that one app is still limited to 4 GB of logical address space. That will change soon but there isn't any rush since nothing really needs that yet.
Actually, I think OSX apps are limited to 2GB of memory. And those of us who push Photoshop and After Effects (think HD video) could easily use 8GB.
I'm the Earth Observatory site designer, and my boss is the Terra Project Scientist-i.e. he's in charge of the satellite that carries MODIS. We work closely with the MODIS rapid response team (http://rapidfire.sci.gsfc.nasa.gov/) who are doing the heavy lifting on data processing (and in turn they rely on the MODIS science team for algorithm development for such things as atmospheric corrections). We do captioning, image annotations, some visualizations, and publishing. The site is the result of a collaboration bewtween a lot of people at NASA. The forest service is more of a data user than data producer.
We're being pointed to from everywhere, but Slashdot is the #1 referrer, followed by Google. The problem isn't so much total bandwidth, but database efficiency, which we're working on. We've also got new servers winding their way through the procurement process.
The main nasa.gov site is handled by a completely different infrastructure.
Actually, the MODIS data of the fires is at 250 m/pixel--well below SPOT's 5m/pixel. The highest resolution data NASA is allowed to acquire (by Congressional statute, I believe) is 15m/pixel. 15m LANDSAT and ASTER data are available to the public for a fee from the USGS, and some scenes are available from a variety of sources for free (http://glcf.umiacs.umd.edu/index.shtml) Any higher res data would (in theory) compete with commercial sector. Ironic since the federal government (primarily DoD) pays the commercial sector $5 million a year for high res data from Ikonos and Quickbird. State and local governments shell out more.
Military satellites (which don't officially exist) may have resolutions of 10cm/pixel.
Interesting--you stopped reading comics when I started. My girlfriend at the time got me into the Sandman after it finished. Aside from the Maxx (by Sam Kieth), which I was introduced to by the MTV series, I had trouble finding anything else that interested me. Things are much better now, however. In additon to Powers: Top Ten (and its spinoff Smax) and League of Extraordinary Gentleman by Alan Moore, Finder by Carla Speed McNeel, Y the Last Man by I forget, and Astro City, by Kurt Busiek.
Lone Wolf and Cub--a Manga originally published in the 70s but recently re-released, is also amazing (if drawn-out by the end).
Actually, you will not be able to find a case as nice as the G5, or even the G4. The new G5 case runs at 35 dB, is almost completely screwless (including the hard drives!), has handles, and looks SWEET. PC cases are getting better, but Apple wins on industrial design, hands down. (with the caveat that there's only 2 drive bays, which sucks)
and the fact that the book carried a warning counted AGAINST Mr. Castillo, because it suggested he knew it contained explicit sexual content

... why are space weather forecasters, satellite operators, and power companies relying on a satellite which is already two years past its most optimistic scheduled lifespan?
because Congress (and various European governments) doesn't want to pay for a new one.
Actually, the raw (black and white, not contrast adjusted) image is saved as a GIF - and it's still pretty big 'cause there's some invisible noise in the black.
In any case, JPEG does LZW (or similar) compression as a final step, so a JPEG would also have been very small if the noise was removed.

a: carbon dioxide is increasing in the atmosphere (see the Climate Monitoring and Diagnostics Laboratory)
b: carbon dioxide absorbs infrared radiation (graph)
So an increase in CO2 should lead to an increase in temperature, which we observe. Any questions?

Sounds like progressive JPEG to me, in which case the patent would apply to browsers.

O'Keefe's only been NASA administrator for 2 years--almost everything NASA is doing now started before he arrived.

Curious -
NASA officially uses SI units. It's the contractors who still use antiquated units.

"The Tempest," as the second of the plays Shakespeare wrote for Morpheus, was integral to the storyline. I don't see it as extraneous.
