Understanding Greenland’s wild climate swings

If we polled climate scientists for the weirdest thing we learned by drilling into Greenland’s ice, Dansgaard-Oeschger cycles would be strong contenders. During the colder parts of Greenland’s ice age history, it has frequently experienced a wicked case of climate whiplash. Parts of Greenland could endure a warming of 10 degrees Celsius in the space of a couple of decades. That would be followed by centuries of cooling and, eventually, another abrupt warming.

Look at ocean sediment cores in the Atlantic and you’ll see something else happening at the same time: sand and stones appearing in the seafloor mud, carried there by dirty, slowly melting icebergs. (In fact, some icebergs may have made it as far as Florida.) These impressive launches of iceberg armadas are called Heinrich events—and there’s clearly some connection between Heinrich and Dansgaard-Oeschger.

We’re pretty sure these wild events relate to the downward flow of salty, dense surface water in the North Atlantic, which completes the conveyor belt that turns northward-flowing surface water into southward-flowing deep water. If the salty surface water loses its greater density, the conveyor belt—and the warmth it carries northward—seizes up. Conversely, switching the conveyor belt back on can rapidly deliver warmth northward, which may explain some of the sudden warmings.

#WMCFW: Hilary MacMillan Fall 2015

wmcfw hillary macmillan

Another family affair, this time in Toronto. Canadian designer Hilary MacMillan's relatively new fashion label is known for its mix of luxurious fabrics and a signature print she develops every season. For fall 2015, she collaborated with members of her family to create a darker, rose and skeleton print.

The color palette was cream, black, bright and dark blood red. While it isn't obvious, the muse behind this season's collection was the Mexican holiday of Day of the Dead. The fashion show combined satins and leather, silk and knits. There were a lot of separates with updated proportions. Long topper jackets were paired with crop tops, loose pants that ended below the knee and jackets with elbow length sleeves. The models sported smokey eyes and slicked "wet look" hair (or they just ran out of the shower onto the runway).


Macmillan put the show in the fashion show, with the band St. Royals entertaining the guests. Guests included the who's who of Canadian showbiz personalities, like 24's Elisha Cuthbert and TV's Supernatural's Richard De Klerk.

Hilary MacMillan is committed to designing and manufacturing her label within Canada. She designs for the modern urban woman like herself. In a short time she has already made fans of all the top Canadian magazines. When you're on a roll, just enjoy the ride!

Washed Up: Alejandro Duran’s Site-Specific Found Plastic and Trash Installations

Derrame

Working along a single stretch of coastline in Sian Ka’an, Mexico’s largest federally-protected reserve, artist Alejandro Duran collects countless bits of trash that washes up from locations around the world. So far he’s discovered plastic debris from dozens of countries on this shore of the Caribbean coast which he utilizes for site site-specific installations for an ongoing project titled Washed Up. By creating aesthetically pleasing landscapes from a disheartening medium, it’s Duran’s hope to create a harsh juxtaposition that draws attention to the global catastrophe of ocean pollution. He shares in a statement about Washed Up:

Over the course of this project, I have identified plastic waste from fifty nations on six continents that have washed ashore along the coast of Sian Ka’an. I have used this international debris to create color-based, site-specific sculptures. Conflating the hand of man and nature, at times I distribute the objects the way the waves would; at other times, the plastic takes on the shape of algae, roots, rivers, or fruit, reflecting the infiltration of plastics into the natural environment.

More than creating a surreal or fantastical landscape, these installations mirror the reality of our current environmental predicament. The resulting photo series depicts a new form of colonization by consumerism, where even undeveloped land is not safe from the far-reaching impact of our disposable culture.

Duran just received the Juror’s Award from CENTER for his efforts, and has upcoming exhibitions at Habana Outpost in Brooklyn and at the XO KI’IN Retreat Center. (via This Isn’t Happiness, LENSCRATCH)

SpaceX releases deck camera footage of Falcon 9 almost-landing

Video: the CRS-6 Falcon 9 almost remotely lands on a barge but then falls over and explodes because space is hard. (video link)

The April 15 launch of SpaceX’s Falcon 9 booster carrying supplies for the International Space Station went well, but the automatic return and landing of the booster didn’t quite work out. Although the rocket was able to navigate to the landing barge waiting for it out in the Atlantic Ocean, video released yesterday shows it coming down too quickly, frantically gimbaling its LOX/RP-1 engines to shed velocity and stay on target.

Today, new video has been released that shows the landing from a different perspective—from the landing barge’s deck. It’s a much closer view of the same landing, showing the booster slewing in from the upper right of the frame. It appears that, at the last moment, the rocket managed to handle its excess of vertical velocity. But that didn't leave it enough time for it to handle its horizontal velocity or the large yaw motion introduced by swinging into position—when it does touch down, it does so at a significant angle.

The small cold-nitrogen reaction control jets near the booster’s apex can be seen frantically attempting to keep the stack upright, but the rocket is already past its tipping point and the jets simply don’t have the thrust. The explosion is only a few frames long, but it’s pretty spectacular.

Mister Triple X at Art Hearts Fashion Fall 2015

art hearts fashion
mister triple x fashion

Who doesn't like a little kink and fetish to heat up the NY Fashion Week runway? 
Mr. Triple X  opened the Art Hearts Fashion Show with a collection body conscious separates for both men and women that were accented with chains and leather straps. The signature pieces were more accessories that could be worn alone for a sexy club (or night in) look or to add some edge to more traditional fashion ensembles. My friends and family were most grateful for the plentiful eye candy of the male models.

The label is designed by Erik Rosete. He intended his collection to be a  high end street wear line for everyone's inner rock star. He is also one of the founders of Art Hearts Fashion organization which brings together artists, designers and creatives to produce events in multiple cities to benefit the AIDS Healthcare Foundation. Before talent management and fashion, he actually started his career as a mortgage banker. Quite a complex background which no doubt benefits him now.

Like what you see? You can support Art Hearts Fashion and the AIDS Healthcare Foundation by texting "FIGHTAIDS" to 41444 to donate any amount you choose.

Raw & Rendered: Experimental 3D Artworks by Joey Camacho

raw-1

In early 2014, Vancouver-based graphic artist Joey Camacho set out to learn more about rendering images using Cinema 4D and Octane Render, with the goal of creating a new piece each day. His first attempts were pretty rudimentary, but it wasn’t long before his exploration and experimentation began to pay off with increasinly subtle details inspired by biology, sound, and geometry. Only several months into his ‘Progress Before Perfection‘ project, he started getting requests for prints as his images were shared widely around Tumblr and elsewhere. You can see more of his work on Behance and prints of many pieces are available through his website.
