Slowing warming by focussing on non-CO2 gases

New study: Slowing climate change by targeting gases other than carbon dioxide
[Via NOAA News Releases]

Carbon dioxide remains the undisputed king of recent climate change, but other greenhouse gases measurably contribute to the problem. A new study, conducted by NOAA scientists and published online today in Nature, shows that cutting emissions of those other gases could slow changes in climate that are expected in the future.

Anthropogenic carbon dioxide is responsible for about 2/3rds of the warming we are seeing. Methane and other greenhouse gases are responsible for the other 1/3rd.

These gases are all more potent greenhouse gases than CO2 but reside in the atmosphere for shorter periods of time.

By reducing these gases by 80% we can hold off or slow down much of the temperature rise for 40-60 years.

This may be an easier thing to handle than totally going after CO2.


The 13 inch Macbook Air is a modern marvel

“The PC world is buzzing lately about how laptop manufacturers are struggling to compete with Apple’s MacBook Air, which has exploded in popularity since the introduction of the third-gen model in 2010. This year’s fourth-gen update is proving to be the must-have laptop of the year. For every laptop manufacturer not named ‘Apple,’ the race is on to make new super-thin and super-light laptops,” Jason Cross reports for PCWorld.

My son got one for his birthday. And the thing is amazing. Faster than anything else we have in a footprint slightly bigger than an iPad.

And so light! It is the perfect laptop for consumin material while also being able to create things, all on the go. He could create a company in a coffee shop. Or create a movie.

The how and why of Apple’s dominance; and why it is not done yet

iPod. iPhone. iPad. Why Apple is Done Inventing New Devices.
[Via Cult of Mac]

Most of Apple’s money comes from recently invented gadgets. More than two-thirds of Apple’s revenue comes from product types that didn’t even exist five years ago (iPhone and iPad). And 78% of Apple’s income is made by products unimaginable just ten years ago (throw in iPod and iTunes).

That means, in order to stay on the same growth curve in the current decade, Apple will have to invent product categories as new as the iPod, iPhone and iPad were, right?

Wrong.

The new products were part of a killer strategy Apple came up with in 1997. Apple will dominate the future by sticking to the strategy, not by trying to invent more product categories.

I have to disagree in part with the article – Apple is not at the end of its innovative cycle. Think innovative networking technology such as white-fi. That will be the final step.

The strategy was to realize that digital content would drive the coming markets – creating it and consuming it. Apple already had a head start on the creating it side. In 1997, it decided to make moves into consuming it.

Almost every move since has been along these lines. It started creating a series of computers designed more for consumption than creation of digital content – first the iMac, then the Macbooks, now the Macbook Air. First no floppy. Then no CD/DVD drives. Everything now comes from digital content served over a network or the Internet.

Then the iPod for consuming music – now no real need for a CD or a CD players. I would bet most CD sales today are made to rip the music into the digital world Apple has helped create.

Then the IPhone – taking an awkward device and bringing it into the age of digital consumption.

Then the iPad –  bridging the gap between digital consumption and creation while providing a unique form factor for entirely new ways to deal with digital.

In Apple’s world, the only physical tools you will need will be Apple’s.  Everything else people will get via Internet downloads. This we now see the reason for iCloud and the fact that their new operating system is download only.

The only thing really hampering Apple in this world – they do not control the connections between the Internet and their  devices. They have all this nice digital content online but have to rely on others to permit the users to get this data.

Apple has had to rely on ATT and now Verizon to provide the connection to the data that Apple wants its customers to access. Or users have to rely on ISPs and wireless hotspots.

But white-fi presents the opportunity for Apple and other high tech companies to  provide these connections between digital devices and the digital realm, without relying on the needs and economic pressures of other corporations. White-fi, for example, has the possibility in certain areas to send a signal 100 km from the transmitter and to permit speeds of 22Mbps.

ATT just accidentally told everyone that upgrading to faster wireless will not cost $38 billion but only $3.8 billion. Pocketchange for Apple and Microsoft. What would happen if a high tech consortium of MS, Apple, Google and others put in money to create their own data service for their customers? Google is already investigating high speed connections for users, as well as wireless transmission.  I expect they all have money in the bank to pay for such a thing. It could use wifi, white-fi, LTE or even new emerging technologies to service their users in ways the wireless carriers still refuse to.

Then Apple and Microsoft will be able to also provide video chatting with their own customers via Face Time and Skype, on handsets whose prodcution they control. Then why would we need the wireless carriers?

So, I think there is one more innovative technology Apple will unveil at some point — the connection to the Internet. Apple will provide the direct connection between the user’s digital device that it sells with the digital data that it serves.

That would be a marvelous day!

Shutting down cell phones by BART not such a good idea

BART statement on killing wireless service in stations on Aug. 11, in anticipation of civil unrest

Finally, here is BART’s cop-out explanation for why they shut down wireless service in Bay Area stations on Aug. 11.

BART temporarily interrupted service at select BART stations as one of many tactics to ensure the safety of everyone on the platform.

Cell phone service was not interrupted outside BART stations. In addition, numerous BART Police officers and other BART personnel with radios were present during the planned protest, and train intercoms and white courtesy telephones remained available for customers seeking assistance or reporting suspicious activity.

Good thing the Bay Area subway system operators are taking a cue from Hosni Mubarak! Because, you know, if an actual riot had occurred, it’s not like anyone affected would have had any need to communicate for help or anything.

There will be a lot of push back against what I am sure BART thought was a good idea. As noted, if there had been an emergency, no one could have called. Imagine the lawsuit BARY would be seeing if someone had a heart attack after they had shut down the cell phones.

Plus, all the protestors have to do now is simply let BART know when a ‘protest’ will be. BART shuts down the cell phones, disrupting their use. The protestors do not even need to show up. They can cause disruptions simply by giving BART dates.

This attempt to control cell phones by authority — something tried by Mubarak in Egypt, contemplated by Cameron in England and no performed in America – is simply counter to what makes for good democracy.

Meanwhile, the Manchester police used social media to deal with the looters. The thing about using a cell phone — there is now a record of what was sent when. Makes for better evidentiary hearings, both for exculpatory evidence or for convictions.

Shutting down technology will only drive the information underground to areas where legitimate authority cannot easily find it.
