Dim Sum in New York

leave a comment »

We had a great Dim Sum luncheon at this place on Saturday, so we went back again on Sunday—still excellent.

Healing the ozone has helped the climate

leave a comment »

Good news from a recent article:

Montreal trumps Kyoto, at least when it comes to global warming.

The 1987 Montreal protocol, which restricts the use of CFCs and other ozone-depleting halocarbons, will be five or six times as effective at reducing global warming as the Kyoto protocol, say researchers at the Netherlands Environmental Assessment Agency (NEAA).

The 2007 assessment by the Intergovernmental Panel on Climate Change (IPCC) estimates that halocarbons now in the atmosphere have a warming effect on the Earth’s surface of 0.34 watts per square metre. Guus Velders of NEAA and his colleagues calculated that, had it not been for the Montreal protocol, this would have nearly doubled.

Another way to quantify the effect of Montreal is to look at how much CO2 emissions would have to be cut to achieve the same effect. By 2010, says Velders, the protocol will have prevented the equivalent of between 9.7 and 12.5 gigatonnes of CO2 being pumped into the atmosphere every year. If all countries meet their Kyoto targets by 2012, the equivalent of only about 2 gigatonnes of CO2 per year will have been saved.

Interesting parallels: cigarettes and global warming

leave a comment »

Two stories from the NY Times today. First is the story of the gradual—and bitterly fought—revelation of the degree to which cigarette smoking adversely affects health. (Emphasis added to highlight the parallels with the next story.)

For many Americans, the tobacco industry’s disingenuousness became a matter of public record during a Congressional hearing on April 14, 1994. There, under the withering glare of Representative Henry A. Waxman, Democrat of California, appeared the chief executives of the seven largest American tobacco companies.

Each executive raised his right hand and solemnly swore to tell the whole truth about his business. In sequential testimony, each one stated that he did not believe tobacco was a health risk and that his company had taken no steps to manipulate the levels of nicotine in its cigarettes.

Thirty years after the famous surgeon general’s report declaring cigarette smoking a health hazard, the tobacco executives, it seemed, were among the few who believed otherwise.

Back home again

leave a comment »

The post title reminds me that when Homer Capehart ran for re-election as US Senator from Indiana, his campaign song was “Back Homer Again in Indiana”. 🙂

But that’s by the way. Megs seems quite happy to see me, and will be even happier as I settle down for a nap—got up at 4:00 a.m. to catch flight home (1:00 a.m. Pacific time). Good flight: non-stop from BWI to SFO had just 43 people on a 757. And the whole visit was good, with stories from the visit still to be posted.

But that will be after a brief nap, during which time my replacement Logitech Revolution mouse will be charging. The old one lost its ability to recharge, so I got a complete new one at no cost. Good tech support, too.

I noticed several articles worth noting on the way home—in the NY Times and New Scientist and the Atlantic Monthly. I’ll post summaries and links later.
