Economists map out economically viable path to renewables-based hydrogen manufacturing

Technical College of Munich (TUM)

Hydrogen manufacturing primarily based on wind energy can already be commercially viable as we speak. Till now, it was usually assumed that this environmentally pleasant power-to-gas expertise couldn’t be carried out profitably. Economists on the Technical College of Munich (TUM), the College of Mannheim and Stanford College have now described, primarily based available on the market conditions in Germany and Texas, how versatile manufacturing amenities may make this expertise a key part within the transition of the power system.

From fertilizer manufacturing, as a coolant for energy stations or in gasoline cells for vehicles: Hydrogen is a extremely versatile fuel. Right now, most hydrogen for industrial functions is produced utilizing fossil fuels, above all with pure fuel and coal. In an

The seas get cooler round Iceland-Some charts and anecdotes

Reader Steinar J writes:

Included is a Phrase doc describing sea temperatures within the neighborhood of Iceland, sea ice extent and an excerpt,
(translated from Swedish) from an eyewitness report from the Swedish icebreaker tour to The North Pole in 2018.

Argo buoys, over three,200 of them, are scattered round within the oceans of the world. These buoys measures the water temperature at numerous depths all the way down to 2000 meters depth. Within the depicted sea space in fig. 1, the temperature has dropped since measurements started at the start of the 2000s. That is in the midst of the Gulf Stream. Right here is the temperature growth within the higher 100 meters:

Putting examine finds a local weather tipping level in clouds

From ARS Technica

We aren’t prone to see it occur, but it surely’s nonetheless sobering.

Scott Ok. Johnson – 2/25/2019, 6:13 PM

Stratocumulus clouds, like these within the decrease two-thirds of this picture, are widespread over the oceans.

The phrase “hysteresis” doesn’t instantly appear threatening; it hints at a portmanteau of “historical past” and “thesis”—a dense learn, maybe, however these by no means killed anybody. However that’s not what the phrase means. Hysteresis is a profound habits some techniques can show, crossing a type of point-of-no-return. Dial issues up only one notch, and you’ll push the system by means of a radical change. To get again to regular, you might need to dial it down 5 or 6 notches.

Earth’s local weather system can present examples. Take the conveyor-belt-like circulation of water within the Atlantic Ocean. Trying again on the previous, you possibly can see instances that

A Uncommon Medical Defence of the Proper to be a Local weather Change Skeptic

FIRM – Freedom and Particular person Rights in Medication

Visitor essay by Eric Worrall

Paul Hsieh, co-founder of Freedom and Particular person Rights in Medication (FIRM), thinks medical practitioners shouldn’t rush to diagnose local weather denial as a psychological dysfunction.

How far ought to therapists and psychiatrists go in taking sides on controversial political points equivalent to local weather change?

Reporter Olivia Goldhill just lately described a chat by psychoanalyst Donna Orange, an adjunct professor at New York College, urging that therapists handle “not simply the demons of a affected person’s unconscious, however the horrors of local weather change.”

Dr. Orange believes that therapists “can draw consideration to the threats posed by local weather change, after which problem the psychological defenses that stop individuals from responding to local weather

Examine: A Photo voltaic Signature in Many Local weather Indices


Jean‐Louis Le MouëlFernand LopesVincent Courtillot

We first apply singular spectrum evaluation (SSA) to the worldwide sunspot quantity (ISSN; 1849‐2015) and the rely of polar faculae (PF; 1906‐2006). The SSA methodology finds 22, 11 and 5.5‐12 months elements as the primary eigenvectors of those photo voltaic exercise proxies. We subsequent apply SSA to the ten Madden‐Julian oscillation (MJO; 1978‐2016) indices.

The primary, most intense part SSA finds in all MJO indices has both a interval of 5.5 or 11 years. The longer‐time period modulation of amplitude is on the order of 1 third of the entire variation. The 5.5‐12 months SSA part 1 of most MJO indices furthermore follows the lowering amplitude of photo voltaic cycles. We then apply SSA to local weather indices PDO, ENSO, WPO, AAO, AMO, TSA, WHWP, and Brazil and Sahel rainfalls. We discover that the primary SSA eigenvectors are all mixtures of quite pure 11,

X-rays Could be a Higher Method to Talk in House

Within the coming years, hundreds of satellites, a number of next-generation area telescopes and even a couple of area habitats are anticipated to be launched into orbit. Past Earth, a number of missions are deliberate to be despatched to the lunar floor, to Mars, and past. As humanity’s presence in area will increase, the quantity of information that’s repeatedly being again despatched to Earth is reaching the bounds of what radio communications can deal with.

For that reason, NASA and different area companies are searching for new strategies for sending data forwards and backwards throughout area. Already, optical communications (which depend on lasers to encode and transmit data) are being developed, however different extra radical ideas are additionally being investigating. These embrace X-ray communications, which NASA is gearing as much as take a look at in area utilizing their XCOM know-how demonstrator.

The replication disaster can also be a concept disaster

From Ars Technica

Idea protects from “private intuitions and culturally biased people theories.”

Cathleen O’Grady – 2/16/2019, 11:00 AM

A jumbled jigsaw puzzle, AKA the state of concept within the behavioral sciences.

A replication disaster has referred to as into query outcomes from behavioral (and different) sciences. Complaints have targeted on poor statistical strategies, the burying of destructive outcomes, and different “questionable analysis practices” that undermine the standard of particular person research.

However strategies are solely a part of the issue, as Michael Muthukrishna and Joseph Henrich argue in a paper in Nature Human Behaviour this week. It’s not simply that particular person puzzle items are low in high quality; it’s additionally that there’s not sufficient effort to suit these items right into a coherent image. “With out an overarching theoretical framework,” write Muthukrishna and Henrich, “empirical packages spawn and develop from private intuitions and culturally biased people theories.”

Hubble Exhibits off the Atmospheres of Uranus and Neptune

Like Earth, Uranus and Neptune have season and expertise modifications in climate patterns in consequence. However in contrast to Earth, the seasons on these planets final for years slightly than months, and climate patterns happen on a scale that’s unimaginable by Earth requirements. instance is the storms which have been noticed in Neptune and Uranus’ ambiance, which embrace Neptune’s well-known Nice Darkish Spot.

Throughout its yearly routine of monitoring Uranus and Neptune, NASA’s Hubble House Telescope (HST) just lately supplied up to date observations of each planets’ climate patterns. Along with recognizing a brand new and mysterious storm on Neptune, Hubble supplied a recent have a look at a long-lived storm round Uranus’ north pole. These observations are a part of Hubble‘s long-term mission to enhance our understanding of the outer planets.
