 Man and Nature

 
April
, 2019

Happenings in the relationship between Man and Nature affecting our hike down life's trail through both worlds. We study both the reality created by humans and the uncreated reality reflected in, and tended by Nature. 

The vast majority of our reporting on Nature comes from the American Association of Scientists summarizations of each day's bounty of the peer-reviewed research published by academic institutions and journals around the world.

Our focus is on everything, every living thing and natural process that we will encounter hiking from Lake Tahoe to Mount Whitney, and out the Portal. The birds, the bees, the water, the trees, the granite in the ground under our feet, and the stars in the sky at night.

Our goal of tracking the status and trajectory of everything we encounter and engage as we hike through the Natural World then brings into play everything it takes to put and keep us out there, which covers a plethora of backpacker-related safety, health, fitness, gear, skills, observation, navigation, and, of course, weather and climate issues.
 

Finally, the most deciseive factor we track that predicts the current status and future trajectory of the health and well-being of Nature are the behaviors, science, culture, and arts of Mankind, who are both one of Nature's greatest and worse creations at the same time. We're going to try to make things better at the bottom-line.

We track the alingment of forces affecting the Nature of our hike through Life on this planet.

You will get the latest news from the forefronts of Climate, Bio, Astro, and the hard sciences affecting our engagement with Nature here, typically two days before hitting the corporate press, but a very long time after they've already deeply affected Man & Nature, if the grimness of our purposeful ecological collapse even comes across the pages of the corporate press at all.

You'll get the real deal here.

CLIMATE, WEATHER, & CURRENT & FUTURE PROSPECTS

The Great Drought is Over

New Era
It appears the drought we've experienced over the past 11 years or so, is finally, and fully over. This last 11 year period of the most extreme period of drought in modern West Coast history (1300 years or 500?) has happened along the clear trajectory of our 30+ year trend of a steadily warming and drying climate on the California Coast and in the High Sierra.

41% Sierra & Rocky Mountains Snow Pack Loss since ‘82

Long Trends-Sharp Extremes
This long warming & drying trend had already remodeled our seasons in the Sierra and West Coast through the gradual, but significant shortening of our Fall, Winter, & Spring seasons we've experienced over the past 30 years, which has reciprocally brought about our new reality of super-extended Summers and short Winters. Well, the extreme drought that rode in on that trend-line of warming and drying weather is finally over. For now.

That trend has been, "bucked," this year! Spring conditions will extend into Summer.

Don't get too comfortable with, "normal," weather, as the long trend-line of warming and drying remains, and continues, unabated.

Quick Changes
2017 & 2018
One Wet Year-One Dry Year
We saw the massive 200% snow season of 2017 (May), which many observers back then were claiming had ended the drought (I refuted that contention), be followed by the 54% snow pack of 2018 (27% in May!), which maintained outright drought conditions, and near-drought conditions across much of California, the High Sierra, and the whole Southwest of the US.

Bouncing Between Extremes
Rapidly
We had seen the extreme tropical activity of the monster El Nino of 2015 all be deflected around California, the Sierra, and Southwest US by monster ridging on the US West Coast, resulting in the driest Winter on record happening during the largest El Nino ever seen.

On the other hand, two years later we watched the extreme, wettest Winter in the history of the Sierra, of 2017, happening during a strong La Nina that was supposed to suppress storm activity on the US West Coast...

Anomolous weather behavior and outcomes have become normal as the system rapidly swings from record-level extreme drought to record-level extreme flood conditions. Nonetheless, we are now part of a trend with two extreme wet years sandwiching the below-normal year of 2018, which has finally knocked us out of drought.

Two of Three Extreme Wet Winters
2017 & 2019
High Saturation

Now, that deluge of 2017 is being backed-up by another in 2019 (April 2), so far.
The normal levels of snow the High Sierra received by January 18 of this year had effectively ended the drought, and has now been significantly accentuated since then by the almost complete dispersal of the blocking ridge so characteristic of the drought era.

All Systems A Go
We will finally enter a Summer with ground water, snow, ground saturation, and reservoir levels all saturated by two out of three years of extreme above average snowpack, for the first time since 2009. The drought is over.

Next
Extremes Continue
My bet is on extremes continuing, as the Northeast Pacific/Arctic weather system has been rapidly moving from one extreme to the other, from super-wet to super-dry years in rapid succession, one after the other, and I expect this trend will continue to move from one extreme to the other. The question is, then, "which extreme will be next?"

Which Way, Whey?
We could be finishing this year's Spring Season in the Sierra Nevada off with Tropical Transport Mechanisms that further fills the Sierra to levels of snow similar to 2017 (200% in May!), or, on the other hand, that same tropical mositure falling as rain across the Sierra in May or June could quickly scour considerable amounts of the snow pack into instantly raging rivers.

I could just as easily imagine the Big West Coast High building-in again, bringing an end to all major storm activity, and ushering in the beginning of the thaw now.

We live in the Theatre of All Possibilities...

My Guess
All Three, in Sequence
It looks to me like we are going to experience scenario #1, with a few more TTMs bringing in warm, wet snows to maintain a near-record snow pack through May, before the West Coast High builds into a heat wave in late June, followed by warm tropical downpours bringing monster thawing and flooding into July. High points on the trail will preserve snow into the beginning of the Winter of 2020.

Right now, I'm figuring the Crest will not be substantially snow-free until late July.
We'll see, but right now I am making my plans based on the extreme amount of snow on the ground, which pushes me towards erring on the side of caution...

Last of the Winter Conditions
Prime Time
Right now we are looking for opportunities to catch the last bit of Winter conditions for some excellent Spring Snow Trips, before the thaw begins in earnest, before snow gets soft, the streams come out of the snow, and the rivers start raging.
