How hot will Earth be by 2100? The answer's in the clouds

ArsTechnica - Tue, 2011/07/05 - 10:37

Understanding the behavior of clouds is key to any accurate projection of future climate (as we’ve covered in the past) because of the complex, competing effects that clouds have on Earth’s energy budget. 

Radiation from the sun in the form of visible light (which climate scientists refer to as "shortwave radiation") is reflected back into space by clouds. An increase in clouds (caused by increasing evaporation that comes with higher temperatures) will thus decrease temperatures by reducing incoming shortwave radiation. We call that a negative feedback—it acts to keep temperatures stable.

But water vapor is also a strong greenhouse gas. In fact, compared molecule for molecule, water vapor absorbs 100 times more outgoing infrared (or "longwave") radiation than does carbon dioxide. That means increasing evaporation will cause temperatures to increase even more. That’s a positive feedback—it acts to exacerbate rising temperatures. 

(Despite its greenhouse potency, water vapor provides a feedback, not a forcing—it can’t initiate temperature increases because its presence in the atmosphere depends on temperature, unlike carbon dioxide or methane.)

PhotoForge 2, Possibly the Best iPad Photo Editing App Yet

Wired: Gadgets - Tue, 2011/07/05 - 09:19
IPad-owning photographers should stop reading right now (well, not right now, or you won't know what to do next) and go download PhotoForge 2, a rather splendid update to the already decent photo-editing app. Better still, if you already bought the iPhone version, the update is free -- the app is now universal. The biggest differences ...

Ask Ars: will iTunes Match be used to chase down music pirates?

ArsTechnica - Tue, 2011/07/05 - 09:00

In 1998, Ask Ars was an early feature of the newly launched Ars Technica. Now, as then, it's all about your questions and our community's answers. Each week, we'll dig into our question bag, provide our own take, then tap the wisdom of our readers. To submit your own question, see our helpful tips page.

Q: Will Apple's iTunes Match service be used to find out who has pirated music?

In the fall, Apple will launch its iCloud service for Macs and iOS devices. It includes two iTunes-related services: free access to previously purchased songs via any authorized device, as well as a $25 per year option to store up to 25,000 songs in iCloud. The latter feature, dubbed iTunes Match, will scan a user's library and give immediate iCloud access to any song that "matches" a corresponding track in the iTunes Store library. Songs that don't match will be uploaded to a user's iCloud storage.

The benefit of iTunes Match over competing services from Amazon and Google is that users with libraries that consist of the most popular content will only have to upload a small percentage of music. This makes the process much faster than uploading each and every track, especially given the relatively anemic upload speeds available to most US broadband users. The US iTunes Store boasts over 18 million tracks, so if your tastes don't depend heavily on obscure, independent, or foreign music, there's a good chance that a significant proportion of your library will match up.

Hands-On: The SoundJaw Fixes the iPad 2's Awful Speaker

Wired: Gadgets - Tue, 2011/07/05 - 07:41
It would be hard to say anything good about the iPad 2's speaker. It is tinnier-sounding than the surprisingly good speaker on the first iPad. It faces backwards, firing all sound away from you. It is far too easy to cover it with a hand or a Smart Cover and -- worst of all -- it is about the ugliest piece of design to come out of Apple since that stupid hockey-puck mouse that shipped back in 1998. Luckily, there's a fix.
