This Bulb

Perhaps we can start a thread for climate change videos.

Apologies if this link doesn't work or translate properly:

This is a link to find the American Meteorological Society Panel on Arctic Ice Change.

There are two options, and the first, 1:44, is the better version.

I like these real player versions because you can drag forward to 25:00 minutes and watch the specific part about the modeled "tipping point" possibly happening now (instead of in 40 years as predicted). See the graphed yellow line!

http://12.170.145.161/Search/advanced.asp?AdvancedQueryText=American+Meteorological+Society+Discussion&StartDateMonth=11&StartDateYear=2007&EndDateMonth=12&EndDateYear=2007&Series=&ProgramIssue=Science%2FTechnology&QueryType=Match+Any+Word&QueryTextOptions=&ResultCount=10&SortBy=bestmatch

...or you can search these terms on CSPAN to get a windows media player.

Environmentally friendly light bulbs ‘can give you skin cancer’

http://www.dailymail.co.uk/pages/live/ar...70&ito=1490

"There have been growing concerns that low-energy light can trigger migraines, as well as dizziness, loss of focus and discomfort among those with epilepsy.
...
Dr Colin Holden, president of the [British Association of Dermatologists], said: "It is important that patients with photosensitive skin eruptions are allowed to use lights that don't exacerbate their condition. Photosensitive eruptions range from disabling eczema-like reactions, to light sensitivities that can lead to skin cancer."

I'm not so hot on the CFL's, but....

This article is an example of horrible journalism.

Yes, "flickering" can be problematic; but is there any association between CFL's and skin problems?

None listed (except in the sensational headline)!

I prefer LED's

...and while I trace back to Leeds,
I think these Spectrum folks (from your link) are only interested in profits.
http://www.its.leeds.ac.uk/projects/spectrum/consortium.html

They are taking a 'BAD' comment out of context, and running with it, I think.

Samwik,
Your link led to a page of links. Which one, specifically, are you referring to?

Do you mean the Spectrum link?

My point was to show Spectrum's focus (transportation, infrastructure, & energy interests); not to say anything about Spectrum's specific links.

I was pointing out that Spectrum may not be an unbiased community advocate.

That is a quote that includes the word cancer. Of course, as others note, what doesn't cause cancer, it is important to know that the risk is increasing.

I don't doubt that there are a few people that are Photolight Sensitive. Time will tell if these new Compact Fluorecent Bulbs
show up this type of sensitivity.
What is also important is that they all contain a couple of milligrams of Mercury. As result they have been banned in some UK schools in case of their accidental breakage, which would release Mercury vapour. Mercury beads are virtually immpossible to find and clean up.
The London Borough of Barnet, (in my area) has banned these bulbs in schools, unless they are protected by an enclosure.

Its also interesting to note that the popular kids shoes that light up while they walk, are activated by a Mercury switch.
