Winter to Spring to Summer 2015-16: Depths of Drought to Depths of Flooding?

December 11 2015

Our goal here is to track each stage of the Fall-Winter-Spring transition to Summer conditions. Our main goal is to determine when trails will open to Summer conditions.

As Fall comes to a close certain patterns have manifested themselves. These have set the stage for the advent of Winter. We've seen that the remnants, the tail ends of the tropical fronts hitting the Sierra have put a reasonable Fall coat of snow on the Sierra.

THE SETTING
Every year the Sierra experiences a different transition from Winter through Spring into Summer conditions. Every year there is a different pattern of "overlap" between the seasons, with bits of warm happening early, and bits of snow and rain happening late.

Contact with nature may mean more social cohesion, less crime

Contact with nature may mean more social cohesion, less crime,
Nov. 25, 2015, American Institute of Biological Sciences.

The scientific evidence is building that Nature is Good for Man.

How about that!

The Original Character of our Nation's Founders was ascribed to their closer contact with "Nature" by both adherents of the European Enlightenment and their Conservative Opponents.

Mutagenic chain reaction could knock malaria out of mosquitoes for good

Very Scary Stuff:
Mutagenic chain reaction could knock malaria out of mosquitoes for good,
Nov 23, 2015, Ars Technica.

I don't like mosquitoes, but releasing a self-replicating, self-modifying gene-sequencing device into mosquitoes in the wild does not seem like a good idea. Franken foods are bad enough without Franken-skeeters.

This also begs the question, what would a world without mosquites look like?

This is not good news for everyone who lives at lower lattitudes than BC, which includes the whole vast population of the United States.

Denge Transmission

 Dengue has been surging out of the expanding tropical areas of the world as tropical conditions push North and South from the Equator. 

The mosquitoes carrying Denge and a whole host of other diseases, and the diseases themselves have ridden the warm currents of climate warming into California, the Sierra, and the Northern Lattitudes.

The attention of pharmacutical companies will increasingly turn to these diseases as richer populations sicken as greed's transformation of our world accelerates.

Oct 1 2015: Cayenne's View Forward

Cayenne just posted a note adding her perspective to the Fall Backpacker's Alert. I thought is was worth sharing more broadly, so here it is:

Killer Bees in North California

‘Killer bees’ found in the Bay Area for the first time,
SF Gate, Sep 28, 2015.

We are going to have to develop "killer-bee safety plans" that address potentially dangerous interactions with "killer bees" on the trail. It's just a matter of time and more heating.
