Welcome to the High Sierra Backpacker's Magazine, including forums for local and long-distance hikers sharing info about hiking the Sierra between Tahoe and Whitney.

This Magazine covers everything Sierra. Its
Forums cover TYT, PCT, & JMT and alt-route hiker input from the Guide. The Tahoe to Whitney Trail Guide explores the trails  & the necessary skills, fitness, and gear required to hike from Tahoe to Whitney. This evolving Magazine covers Current Conditions, News, the Arts, Sciences, Physicality, Spirituality, Gear, Environment, History, and Cultures of hiking Tahoe to Whitney.

Generally Bad for Bodies
"...found in 2015 that soybean oil induces obesity, diabetes, insulin resistance, and fatty liver in mice. Then in a 2017 study, the same group learned that if soybean oil is engineered to be low in linoleic acid, it induces less obesity and insulin resistance."

The Bottom Line

Escape from the Tech Trap

Our rising technological understanding of the physical reality around us has shifted humanity's fundamental challenge, which started with basic physical survival, into the sphere of the spiritual and motivational world.
As the scope and power of our technological understanding evolved to threaten all of us, and all life on this planet, it has become vitally important that the brutal operating code that our physical reality operates on, that, "life eats itself to survive," be put aside, by us, for our own survival.

When, Where, & How We Spread Globally

A handful of recent discoveries have shattered anthropologists' picture of where humans came from, and when,
Business Insider, January 5, 2020

MAIN POINTS

New Picture Emerging
A New Puzzle, Really...
"A 2017 finding in Morocco threw into question the idea that modern humans originated in East Africa. Those bones were significantly older than any others ever found."

Trickle?
"The initial dispersals out of Africa prior to 60,000 years ago were likely by small groups of foragers, and at least some of these early dispersals left low-level genetic traces in modern human populations."

Flood?
"A later, major 'Out of Africa' event most likely occurred around 60,000 years ago or thereafter."

Amazon Regeneration Slower that Thought

 

TREE NEWS
Killing the Whole Planet

The Amazon is Crashing

Amazon deforestation is close to tipping point,
Fundação de Amparo à Pesquisa do Estado de São Paulo, March 19, 2018.

 FULL CRASH MODE APPROACHING

"Deforestation of the Amazon is about to reach a threshold beyond which the region's tropical rainforest may undergo irreversible changes that transform the landscape into degraded savanna with sparse shrubby plant cover and low biodiversity."

"The Amazon system is close to a tipping point."

OLD TIPPING POINT

"...the tipping point would be reached if approximately 40% of the region were deforested." 

NEW TIPPING POINT

"...climate change and indiscriminate use of fire...indicates a shift to non-forest ecosystems in the eastern, southern and central portions of the Amazon region at between 20% and 25% deforestation."

Amazing Human-Climate Interactions

What a Long, Strange Trips It’s Been

Ancient farmers spared us from glaciers but profoundly changed Earth's climate,
University of Wisconsin-Madison, September 6, 2018.

MAIN POINTS

Human Global Warming began a Long Time Ago
“Millenia ago, ancient farmers...may have been fundamentally altering the climate of the Earth.“

Ice Age Averted
“...without this human influence, by the start of the Industrial Revolution, the planet would have likely been headed for another ice age.”

First Human Tipping Point
“...the Holocene reversed direction 5,000 years ago, hitting peak concentrations of both gases by 1850.”

The Long Cycle
“For most of Earth's 4.5-billion-year history, its climate has largely been determined by a natural phenomenon known as Milankovitch Cycles, periodic changes in the shape of Earth's orbit around the sun - which fluctuates from more circular to more elliptical - and the way Earth wobbles and tilts on its axis.“

WHERE WE AT

Earth Closest to the Sun

The Earth at Perihelion,
In-The-Sky, January 6, 2020.

MAIN POINTS

Closest at Mid-Winter
"The Earth's annual orbit around the solar system will carry it to its closest point to the Sun, at a distance of 0.98 AU."

Annual Variation
"The Earth's distance from the Sun varies by around 3% over the course of the year because its orbit is slightly oval-shaped, following a path called an ellipse."

"...a 3% difference in the Earth's distance from the Sun is barely noticeable."

Our Tilted Engine of Weather
"Annual changes in our weather, for example between the summer and winter, are caused entirely by the tilt of the Earth's axis of rotation, rather than by any change in its distance from the Sun."

Tipping Points Falling Like Dominoes

Nine Climate Tipping Points Now 'Active,' Warn Scientists,
University of Exeter, November 27, 2019.

MAIN POINTS

"More than half of the climate tipping points identified a decade ago are now "active", a group of leading scientists have warned."

"This "cascade" of changes sparked by global warming could threaten the existence of human civilisations."

"...these events are more likely and more interconnected than was previously thought, leading to a possible domino effect."

"...we must admit that we have underestimated the risks of unleashing irreversible changes, where the planet self-amplifies global warming."

Moron Alert
"Scientifically, this provides strong evidence for declaring a state of planetary emergency, to unleash world action that accelerates the path towards a world that can continue evolving on a stable planet."

Easy Money
"Exiting the fossil fuel economy is unlikely before 2050, but with temperature already at 1.1°C above pre-industrial temperature, it is likely Earth will cross the 1.5°C guardrail by 2040."

Nine active tipping points:
