Two Stories: New York Times & Ars Technica

 

An Invasive New Tick Is Spreading in the U.S.,
New York Times, August 6, 2018.

"...is spreading rapidly along the Eastern Seaboard. It has been found in seven states and in the heavily populated suburbs of New York City."

"It’s not known when or how long-horned ticks reached the United States, nor why the species is spreading so fast now."

"In theory, just one female could have produced all the long-horned ticks spreading in the country through asexual reproduction. But Dr. Egizi said she has found three mitochondrial DNA lineages, meaning at least three females arrived."

University of Helsinki, December 13, 2018.

MAIN POINTS

“...the abundances of mountain-specialist birds has declined by as much as 10% in the 2000s. ”

Running our of “Running” Room
“These species are also very susceptible to climate change, as global warming is reducing their liveable habitats. In principle, species may relocate further up the mountains, but closer to the top their habitat inevitably shrinks.”

Cause
It’s Us!
“...declined in line with climate change projections.”

Short Answer: Yup!

Organic food worse for the climate,
Chalmers University of Technology, December 13, 2018.

MAIN POINTS

"Organically farmed food has a bigger climate impact than conventionally farmed food, due to the greater areas of land required."

Massive CO2 Increases
“Our study shows that organic peas, farmed in Sweden, have around a 50 percent bigger climate impact than conventionally farmed peas. For some foodstuffs, there is an even bigger difference – for example, with organic Swedish winter wheat the difference is closer to 70 percent...”

Despite More Intense Rain, Blue Water Decline from Warmer Soil’s Reduced Runoff

WATER SUPPLY SHRINKING GLOBALLY

Blue Water Decline from Warmer Soil’s Reduced Runoff

The long dry: why the world's water supply is shrinking,
University of New South Wales, December 13, 2018.

MAIN POINTS

More Rain = Less Water
“...our water supplies are shrinking at the same time as climate change is generating more intense rain.”

Scope
“...the most exhaustive global analysis of rainfall and rivers...”

No Models
“...relied on actual data from 43,000 rainfall stations and 5,300 river monitoring sites in 160 countries, instead of basing its findings on model simulations of a future climate, which can be uncertain and at times questionable.”

Results
"We expected rainfall to increase, since warmer air stores more moisture - and that is what climate models predicted too. What we did not expect is that, despite all the extra rain everywhere in the world, is that the large rivers are drying out.“

July’s, “Bay-Delta Plan,” Reducing California River Water Withdraws, PASSED

WATER is for FIGHTING

July’s, “Bay-Delta Plan,” Reduced River Water Withdraws, PASSED

State board approves controversial river flows. What’s the next step for MID, TID?
Modesto Bee, December 12, 2018.

This article above & below references the Dept of Water Resources, “Bay-Delta Plan,” of last July:
California proposes reducing river flows for farms & cities

MAIN POINTS

“The state board, on a 4-1 vote Wednesday, approved a Bay-Delta plan that includes what the districts consider unacceptable flow requirements for the Tuolumne River, as well as the Stanislaus and Merced rivers, a decision that’s expected to spawn lawsuits in the next 30 days.”

Scammers
“The MID and TID, and its partner the San Francisco Public Utilities Commission, wanted more time for an environmental review on the voluntary settlement negotiated with representatives of the state Department of Fish and Wildlife and Department of Water Resources.”

Snow over Antarctica buffered sea level rise during last century,
NASA/Goddard Space Flight Center, December 13, 2018.

 

MAIN POINTS

Steadily Increasing Snowfall
“...an increase in snowfall accumulation over Antarctica during the 20th century mitigated sea level rise by 0.4 inches. However, Antarctica's additional ice mass gained from snowfall makes up for just about a third of its current ice loss.”

“...without these gains, we would have experienced even more sea level rise in the 20th century."

2,500 year old, 881,849 pound, Quarter-Square Mile Super Mushroom

'Humongous fungus': 25 years later, this Armillaria gallica is bigger than first thought, says researcher,
Physorg, University of Toronto, November 14, 2018.

MAIN POINTS

Discovered
“In 1992...estimated that the honey mushroom, which is growing in a forest on Michigan's Upper Peninsula, was 1,500 years old, weighed 100,000 kilograms and covered 15 hectares.

Today’s Estimate
“Using current research and analytic techniques...that the mushroom is at least 2,500 years old, weighs 400,000 kilograms and covers about 70 hectares.”

"I view these estimates as the lower bound."

NPR, December 12, 2018.

2018 NOAA Arctic Report Card

MAIN POINTS

Vast Transformation
“The Arctic has experienced the "most unprecedented transition in history" in terms of warming temperatures and melting ice, and those changes may be the cause of extreme weather around the globe, according to the National Oceanic and Atmospheric Administration's 2018 Arctic Report Card.”

“...rapid warming over the past three decades has led to a 95 percent decline of the Arctic's oldest and thickest ice.”

CHAOS
“...it may be the catalyst for extreme environmental events across the world.”

Greenland Ice Sheet Melt 'Off the Charts' Compared with past Four Centuries

Updated
December 10th!

 

ECO-CRASHING OCEAN NEWS

Waterworld on the Way

Greenland ice sheet melt 'off the charts' compared with past four centuries,
Woods Hole Oceanographic Institution, December 5, 2018.

MAIN POINTS

“Ice loss from Greenland is one of the key drivers of global sea level rise.”

Overdrive
"Melting of the Greenland Ice Sheet has gone into overdrive. As a result, Greenland melt is adding to sea level more than any time during the last three and a half centuries, if not thousands of years."

"And increasing melt began around the same time as we started altering the atmosphere in the mid-1800s."

Off the Charts
“From a historical perspective, today's melt rates are off the charts, and this study provides the evidence to prove this"

Vast Increases in Melting
"We found a fifty percent increase in total ice sheet meltwater runoff versus the start of the industrial era, and a thirty percent increase since the 20th century alone."

Totten, & More Glaciers in East Antarctica Are Waking Up

Totten and Four Neighbors are Moving,
NASA Earth Observatory, December 11, 2018.

MAIN POINTS

It’s Moving
“...scientists have long considered the eastern half of the continent to be more stable than West Antarctica. Now new maps of ice velocity and elevation show that a group of glaciers spanning one-eighth of the East Antarctic coast have been losing some ice over the past decade.”

Fast
“...found that the surface height of four glaciers west of Totten, in an area facing Vincennes Bay, has dropped by an average of nearly three meters (9 feet) since 2008.”

East Antarctica on the Move
“Such levels of ice loss are small when compared to those of glaciers in West Antarctica. But still they speak of nascent and widespread change in East Antarctica.”

Delta Stewardship Council Hurdle Derails Devils Straws

A Temporary Reprieve

LATEST UPDATE

Delta tunnels won’t get green light before Gov. Brown leaves office. What will Gavin Newsom do?
Sac Bee, December 7, 2018.

MAIN POINTS

Dead for Now!
“...the Department of Water Resources withdrew its petition to the Delta Stewardship Council to have the project deemed in compliance with what’s known as the the Delta Plan, a set of policy goals, mandated by state law, that put protection and restoration of the fragile Sacramento-San Joaquin Delta estuary’s eco-system on an equal footing with more reliable water supplies.”

“Without the council’s green light, the $16.7 billion project, known officially as California WaterFix, can’t go forward.”

“Now they have to go back to the drawing board and prepare a new certificate.”

“it’s hard to see how these issues could be fixed quickly.”

Spider Babies Like Spider Milk

AMAZING LIFE

Spider Babies Drink Spider Milk

The Next Health Food Fad for Yuppies we will see at Whole Foods?

Until leaving the nest, jumping spiders suckle spider milk from their moms,
American Association for the Advancement of Science, November 29, 2018.

MAIN POINTS

Spider Milk!
“...some baby jumping spiderlings are entirely dependent on nutritious spider milk secreted and fed to them by their mothers. What's more, spider mothers continue to care for and feed their offspring the nutritious milk-like fluid - which contains nearly four times the protein of cow's milk - into their subadult lives and long after they're able to forage on their own.”

8 Spider Tits?
“...the possibility that long-term, milk-provisioning maternal care may be more common in the animal kingdom than previously believed.”

Spider Maternity
“While lactation-like provisioning is known elsewhere in the animal kingdom, the intensity and duration of associated parental care is uniquely mammalian and thought to increase fitness by providing the opportunity for offspring to learn behaviors crucial for survival.”

All Starlight EVER Measured Through Time’s Foggy Lens

 

ASTROPHYSICS PHUN

Let There be Light. Lots of Light

All Starlight EVER Measured Through Time’s Foggy Lens

Clemson scientists measure all of the starlight ever produced by the observable universe,
Clemson University, November 29, 2018.

MAIN POINTS

The Great Fog
“...gamma rays (the most energetic form of light) and their interaction with the extragalactic background light (EBL), which is a cosmic fog composed of all the ultraviolet, visible and infrared light emitted by stars or from dust in their vicinity.”

How Thick
“...using Fermi's Large Area Telescope data to analyze the extragalactic background light. Starlight that escapes galaxies, including the most distant ones, eventually becomes part of the EBL. Therefore, accurate measurements of this cosmic fog, which have only recently become possible, eliminated the need to estimate light emissions from ultra-distant galaxies.”

ARRIVAL of the WINTER of 2019

ARRIVAL of the WINTER of 2019

Current Progress, Comparisons, and the Arts of Prognostication

Warm North Pacific
The anticipated El Nino is not happening, so far at least, as cool water continues to surface off the central-Western coast of South America. But, we are having what appears to be a, "Northern El Nino," with abberant warm waters persisting in the Gulf Alaska, and generally warmer than normal water spread all around & across the North Pacific. Weird...

Tracking El Nino

Nonetheless, we’re looking a lot better this year than last, having 108% of a normal snowpack on December 5th this year, compared to the 23% of average on December 29th of 2017.

Last year’s snowpack total came in at 58% of average, only being preserved, and luckily, being stretched-out to human-use sufficiency, by the cool temps and late-season storms we experienced through last year's Spring.

Will we get so little snow, and be so lucky with its timing, this year as we had last year?

'CRISPR Babies' Scientist Just Defended His World-Shattering Research in First Public Appearance,
Science Alert, November 28, 2018.

MAIN POINTS

“He Jiankui, the Chinese researcher who claimed this week to have helped produce the world's first genetically altered babies, said Wednesday there was another "potential pregnancy" involved in his study...”

“...he had successfully altered the DNA of twin girls while they were embryos to make them resistant to HIV infection, the Stanford-trained bioengineering professor said he felt "proud" of his work and its implications for public health in the face of nearly universal condemnation.”

“...31 embryos created through in vitro fertilization, and 70 percent were successfully edited.”

“...raised the prospect of a future in which parents produce "designer babies" with selectively improved traits such as intelligence or strength.”
