Continuation of Present Warming NOT an “EXISTENTIAL THREAT”

Proxy Temperatures & Historical Records show continuation of the present warming is NOT an “EXISTENTIAL THREAT” to humans

 Robert W. Endlich

US President Joe Biden has declared

“Climate change is literally an existential threat to our nation and to the world.”

By this he means

“human-caused, CO2-fueled global warming,”

and he presumes that humans can pass “climate legislation” to regulate the climate.  While this view is popular in Media, Government, and the Academy (academia,) I show that it is without foundation.

Here’s the United Nations with a similar story on this same subject:

“… (the) UN Secretary-General insisted that unless governments everywhere reassess their energy policies, the world will be uninhabitable.” Continue reading “Continuation of Present Warming NOT an “EXISTENTIAL THREAT””

Kinetic Space Launch

With Emphasis on SpinLaunch 

William M. Gutman
Introduction 

Kinetic space launch refers to a launch in which the vehicle is imparted very high initial velocity and leaves the launch apparatus at maximum speed. The vehicle, at least initially, is a simple projectile.

Centrifugal accelerator built by SpinLaunch at NM Space Port.

The highest velocity occurs at exit where atmospheric pressure is highest. Therefore

      • The dynamic pressure on the vehicle is highest.
      • Atmospheric drag is highest.
      • Aero-thermal effects are highest.

Currently, no one pursuing kinetic launch systems expects to reach orbit directly with a kinetic system.  Rather, a second stage rocket will be used to attain the final increment of orbital speed.  Companies do, however, expect to exceed the Karman Line.  The Karman Line is the most commonly used definition of the threshold of space.  It is 100 km Continue reading “Kinetic Space Launch”
