Some weeks later, after radiation therapy that was designed to limit the extent of the surgery, he wrote to tell me that the doctors were astounded to learn that the tumor had been stopped cold by the radiation and that surgery would not be required.

«It is likely that very few Americans will be killed directly, suffer radiation sickness, or even have a measurably increased risk for cancer from an attack,» Peter D. Zimmerman and Cheryl Loeb write in «Dirty Bombs: The Threat Revisited,» a report published by the Center for Technology and National Security Policy, National Defense University.

Soon said he is required by the center to recite a disclaimer — saying his views are his own, and not that of Harvard - Smithsonian — each time he speaks or writes on anything outside his expertise in solar radiation.

http://www.vukcevic.talktalk.net/NFC1.htm http://www.vukcevic.talktalk.net/LFC20.htm Re UV: This is a copy of a note I wrote some 5 - 6 years ago with minor changes (I occasionally quote it here and there since I think it still has some merit) Both UV and the particle radiation (particle radiation is a function of solar activity and the strength of Van Allen belt, via the Earth's field strength) could have far larger indirect contribution by controlling plankton volumes, and in turn changing the oceans» clarity and CO2 absorption.

Turgid undergraduate books about heat transfer in university libraries all write that radiation emitted by a colder body is absorbed by a hotter body.

Remembering an old post I wrote, I dug up this paper (open access) by Damon Matthews and Ken Caldeira, which modelled geoengineering by reducing incoming solar radiation uniformly across the globe.

There, it is written that the absorption of surface radiation by CO2 is saturated and that the decrease in the global outgoing longwave emission due to more CO2 in the air is only due to the «higher and cooler» emission level of tropospheric CO2 radiating to the cosmos.

Then, for the benefit of the lay reader, who would not be expected to understand the clear (to a competent physical scientist) implication of this simply - stated fact, I wrote: «This in fact indicates that the Venusian atmosphere is heated mainly by incident infrared [not the VISIBLE portion, which is indeed largely reflected, defenders, but INFRARED] radiation from the Sun, WHICH IS NOT REFLECTED BUT ABSORBED [or allowed in to heat the lower atmosphere] by Venus's clouds, rather than by warming first of the planetary surface.

«6: Incomprehensible...» ANSWER: figure 6 - A to 6 - D explain the basic physics of the radiative effect of trace gas in the air; cards n ° 14, 15, 16 explain further the basics that are supposed to be understood by anyone speaking or writing about radiation in the air.

They come up with all kinds of hypothetical feedback mechanisms involving more natural aerosol emissions in response to global warming: Dimethylsulfide from marine phytoplankton (although a very intriguing possibility, this has never been confirmed to be a significant feedback mechanism, and there is ample evidence to the contrary, which is omitted from the report), biological aerosols (idem), carbonyl sulfide (idem), nitrous oxide (idem), and iodocompounds (idem), about which they write the following: «Iodocompounds — created by marine algae — function as cloud condensation nuclei, which help create new clouds that reflect more incoming solar radiation back to space and thereby cool the planet.»

David Springer wrote: The greenhouse effect, by trapping infrared radiation, can lower the albedo of the earth and cause global warming.
