What has happened to the National Academy of Sciences  – Part Two

INTRODUCTION

In Part One, I described when, over a fifteen or so year period of my work assignments, I needed current knowledge of the toxicity of chemicals used in military applications. From 1976-1979, the chemicals were Unsymmetrical Dimethyl Hydrazine, and Nitrogen Tetroxide, propellants for the Air Force Titan 2 Missile. Then, 1984-1994, the chemicals were Fluorine, Nitrogen Trifluoride, and Hydrogen Fluoride (HF) [actually its deuterated fluoride isotope cousin (DF)] for the Navy’s MIRACL laser at White Sands Missile Range (WSMR).  In those days my colleagues and I respected and trusted the National Academy of Sciences Committee on Toxicology, and by inference the National Academy itself.  For me, that period in my work history ended in 1994.

DOUBTING ALLEGED CO2 CLIMATE EFFECT

My beginning of doubt into significant “human-caused, CO2-Fueled Global Warming” arose after James Hansen’s 23 Jun 1988 testimony to the Senate, Continue reading “What has happened to the National Academy of Sciences  – Part Two”

The Madden-Julian Oscillation: a weather system Wikipedia lists under Climate Change

by Robert W. Endlich

A significant weather system which affects the globe was not even discovered until the 1970s, perhaps because it is stronger in the Southern Hemisphere than the Northern. This system, the Madden-Julian Oscillation, is an area of enhanced rainfall with these characteristics:

The enhanced precipitation anomaly starts in the Indian Ocean; it always moves eastward, and usually moves from Indian Ocean into mid-Pacific at speeds of 9-19 Miles/Hour. In addition to the enhanced precipitation area itself, there is an associated area of suppressed precipitation, an out-of-phase area ahead of it, usually way out ahead of it. The disturbed weather areas usually last 30 to sometimes 90 days.

The convective precipitation signature of this system is strongest within 15 degrees north and south of the Equator. Continue reading “The Madden-Julian Oscillation: a weather system Wikipedia lists under Climate Change”
