A favourite lie of the environmental movement takes another blow

The LNT model encapsulates the idea that there is no safe level of radiation exposure, no threshold below which exposure is not a problem.

Why toxicologists resisted and radiation geneticists supported EPA’S adoption of LNT for cancer risk assessment

Precipitable Water Redux

Guest Post by Willis Eschenbach In my last post I investigated the mathematical relationship between the amount of total precipitable water vapor (TPW) in the atmosphere, and the clear-sky greenhouse effect. Here is the main figure from that post showing the relationship: Figure 1. Scatterplot, TPW (horizontal scale) versus Atmospheric Absorption (vertical scale). Dashed yellow…

Precipitable Water

Guest Post by Willis Eschenbach One of my great pleasures is to come across a new dataset. Turn me loose on new observations of this magical world, and there’s no telling where I’ll end up. Thanks to a recent article here on WUWT I got to thinking about water vapor. Some research found the RSS…

The next big worry: Claim of major U.S. aquifers contaminated by Uranium – but is it really a problem to health?

Study: 2 major US aquifers contaminated by natural uranium Naturally occurring uranium is being mobilized by farm-related pollution From the University of Nebraska, Lincoln. Nearly 2 million people throughout the Great Plains and California above aquifer sites contaminated with natural uranium that is mobilized by human-contributed nitrate, according to a study from the University of…

Silver Ants

Guest Post by Willis Eschenbach I stumbled across a lovely article about the Saharan silver ant over at phys.org. These ants have special hairs that reflect strongly in the visual and radiate strongly in the infrared. They show a photo of the ant hairs under a couple different amounts of magnification: Figure 1. Photograph from the phys.org…

The Desert Finder

Guest Post by Willis Eschenbach Despite doing lots of research and investigations over the last few weeks, I’ve written little. Well, actually, I’ve published little, although I’ve written a lot. But I didn’t publish what I’d done, there was no wonder in it, no awe. So I tossed it all out and started “simply messing…
