Share Leonardo DiCaprio’s Jetset Climate Burden

Watts Up With That?

Guest essay by Eric Worrall

The Verge has written one of the most unintentionally hilarious descriptions ever of serial Climate Clown Leonardo DiCaprio’s desire to share his green angst with the proletariat.

… Celebrities are keen on adopting righteous causes, but few are as vocal as Leonardo DiCaprio about his quest to save the planet from ecological collapse. “I am consumed by this,” DiCaprio told Rolling Stone in a profile earlier this year. “There isn’t a couple of hours a day where I’m not thinking about it.”

With Before the Flood, DiCaprio is asking us to sample a fraction of his daily burden. Directed by Fisher Stevens, Before the Flood documents DiCaprio as he jet-sets from Greenland, to Indonesia, to Miami and beyond, speaking to world leaders and, per the film’s liner notes, “bearing witness to climate change on a scale that no one should deny.” In the vein of…

Mystery as stratospheric wind patterns change for first time in 60 years of observations 

Lowest solar cycle in a hundred years, 60 odd years of observations….must be climate change *palms forehead*

Another climate mystery – this time the QBO – for scientists to get their teeth into, as the Mail Online reports.

For more than 60 years, atmospheric scientists have observed the consistent behaviour of a wind pattern known as the ‘quasi-biennial oscillation’ – a phenomenon that repeats every 28 months. But in late 2015, the long-reliable pattern suddenly changed. 

The winds have since returned to their normal course, and while no immediate effects were detected, astronomers are working to understand if this was just a one-time ‘black swan’ event, or a ‘canary in the coal mine’ signalling unseen conditions.

From COSMOS: “How do spacecraft get a speed boost from gravity assists?”

No rocket ever made could have provided the acceleration, or deltaV budget, to propel Rosetta to the speed it needed to rendezvous with comet 67P. ESA

Back in 2014, the Rosetta spacecraft arrived at its destination, comet 67P/Churyumov-Gerasimenko, after a 10-year journey. The moment was significant as it again demonstrated that how much fuel a spacecraft carries did not necessarily determine how far it could go.

But how was this possible and what forces are at play when it comes to making spacecraft travel further than they should?

Scientists designing rocket missions have a few tricks up their sleeve that allow them to accelerate an object to a speed that is higher than its fuel store would allow. To understand this better let’s start with how astronomers and space scientists view energy.

Earth sized planet found orbiting our sun’s nearest neighboring star, Proxima Centauri

Watts Up With That?

From Nature (h/t to Dr. Leif Svalgaard)

Astronomers have discovered evidence of a small, rocky planet orbiting our nearest star – and it may even be a bit like Earth. Nobody knows whether the planet, called Proxima b, could ever sustain life. The little planet orbits our sun’s nearest neighboring star, Proxima Centauri, making it the closest exoplanet ever found.

proxima-centauri

Proxima Centauri, the star closest to the Sun, has an Earth-sized planet orbiting it at the right distance for liquid water to exist. The discovery, reported today in Nature1, fulfils a longstanding dream of science-fiction writers — a potentially habitable world that is close enough for humans to send their first interstellar spacecraft.

“The search for life starts now,” says Guillem Anglada-Escudé, an astronomer at Queen Mary University of London and leader of the team that made the discovery.

Humanity’s first chance to explore this nearby world may come…

Spencer Axani

A doctoral student and his adviser designed a tabletop particle detector they hope to make accessible to budding young engineering physicists.

When Spencer Axani was an undergraduate physics student, his background in engineering led him to a creative pipe dream: a pocket-sized device that could count short-lived particles called muons all day.

Muons, heavier versions of electrons, are around us all the time, a byproduct of the cosmic rays that shoot out from supernovae and other high-energy events in space. When particles from those rays hit Earth’s atmosphere, they often decay into muons.

Muons are abundant on the surface of the Earth, but in Axani’s University of Alberta underground office, shielded by the floors above, they might be few and far between. A pocket detector would be the perfect gadget for measuring the difference.

Now a doctoral student at Massachusetts Institute of Technology…

Rainbow Cloud or Earthquake Light in the sky over Poland

Behind The Scenes 24 News

Rainbow Cloud earthquake lights Phenomenon PolandAccording to the video uploader a spectacular rainbow cloud appeared over the city Rybnik in southern Poland end of July 2016.

According to a meteorologist from a TV weather channel, the unusual shape and colors above the clouds is a so-called rainbow cloud, it arises as a result of the passage of sunlight which breaks down the ice particles in clouds at certain heights, but I am not sure if it is just an unusual optical sky phenomenon. Is it possible that this phenomenon is an earthquake light?

An earthquake light is an unusual luminous aerial phenomenon which takes many forms that reportedly appears in the sky before an earthquake and something afterwards and could provide an early warning sign. It is known that earthquake lights appear weeks up till minutes before an earthquake occurs.

Appearances of the earthquake light seem to occur when the quakes have a high magnitude, generally 5 or higher on the Richter…

The Sun will Turn into a “Ring of Fire”

Behind The Scenes 24 News

The Sun will Turn into a Ring of FireOn September 1, 2016 the moon will block much of the sun in
a so-called annular solar eclipse, also known as a “ring of fire” solar eclipse.

On September 1st, skywatchers in parts of Africa will see the Moon pass directly in front of the Sun, creating an annular solar eclipse.

During an annular solar eclipse, the Moon is farther away from Earth than during a total solar eclipse, so it appears smaller and doesn’t completely cover the Sun.

A partial solar eclipse will be visible from most of the African
continent.

The annular solar eclipse will be visible from Madagascar and locations in Central Africa. The Moon’s shadow will also cross parts of the Atlantic and Indian Oceans. For most viewers in Africa, the eclipse will be a partial solar eclipse.

The eclipse will begin at 06:13 UTC on September 1, 2016.
The maximum point will take place at 09:01…

University of Adelaide research has for the first time statistically proven that the earliest standing stone monuments of Britain, the great circles, were constructed specifically in line with the movements of the Sun and Moon, 5000 years ago. H/T ScienceDaily

The research, published in the Journal of Archaeological Science: Reports, details the use of innovative 2D and 3D technology to construct quantitative tests of the patterns of alignment of the standing stones.
