'If we can make a space station fly, we can save the planet': An astronaut's view on protecting the Earth – CNN

Published

 on


(CNN)French astronaut Thomas Pesquet spent six months aboard the International Space Station last year, and his view of the Earth was as alarming as it was breathtaking.

Long periods with his feet off solid ground gave him a unique and privileged perspective on our planet. His Instagram account is bursting with beautiful images of “the blue ball we call home.” But the beauty is tainted. Pesquet says that even from space the effects of climate change are visible.
He says that since his previous visit to space, in 2016, the consequences of human activity have become even more apparent, with glaciers visibly retreating, and a rise in extreme weather events.
Environmental concern motivated him to become a UN Food and Agricultural Organization (FAO) Goodwill Ambassador. As an astronaut on board the ISS he supported the FAO’s research into agricultural innovation and methods of food production. Limited resources in space provide an opportunity to model human behavior on a planet with dwindling resources, and Pesquet wants to highlight the parallels between life on a spacecraft and life on Earth.
CNN spoke to Pesquet at the Houston Museum of Natural Science. This interview has been edited for clarity and brevity.

The astronaut caring for ‘spaceship Earth’ 04:04
CNN: What does the Earth look like from “out there?”
Pesquet: When you look at the Earth from the space station, it’s absolutely magical. You’re not that far away, so you still have a relatively close-up view. But you can see the curvature and you see the atmosphere. It glows in blue. It is absolutely breathtaking the first time you see it. It’s the most beautiful scenery you could possibly imagine.
When you’re on the Earth, you feel that everything is so vast, everything is endless. You have a hard time understanding how limited we are. Then, when you take a step back and you see the Earth in its entirety, you suddenly understand that we live in an oasis in the cosmos. All around us is nothing, no life, blackness, emptiness, absolutely nothing — apart from this blue ball with everything we need to sustain human life, and life in general, which is absolutely fragile.
It makes you want to cherish the Earth and protect it, the more you see it from space.
CNN: What are the real effects of climate change that are visible from space?
Pesquet: You can see a lot of the consequences of human activities from space. Some of them are from climate change, and some of it is just plain old pollution, e.g. river pollution, air pollution.
The most visual visible effect is glaciers retreating year after year and mission after mission.
But what you can see as well is extreme weather phenomena. They’re getting stronger and stronger year after year. My first mission was 2016-2017, and my second mission was five years later in 2021. I could see a net increase in the frequency and the strength of extreme weather phenomena like hurricanes, like wildfires.
CNN: What contribution can an astronaut make?
Pesquet: There’s a ton that you can do from space to help out on the planet. First of all, as a space agency, we have satellites that can observe the Earth and measure variables such as the heights of waves, the temperature of the sea, ice on the polar caps retreating.
But we can also go a little bit deeper. We have experiments that are geared towards protecting the planet — for example, experiments on fluids. Fluids in orbit behave differently, so our research is trying to understand the motion of the magma and lava inside the planet, and the movement of waves in the ocean. This can help us predict some of the extreme weather events that affect our environment.
Crucially, we have to manage our limited resources onboard the space station. We have limited atmosphere, limited water, limited food. And so the way we deal with everything on board the space station gives us techniques that we can apply on Earth because the situation is parallel. I think the people on Earth can learn a great deal about how space technology deals with water, how we recycle water, how we recycle air oxygen.
CNN: Does it take its toll on family life when you’re away in space for several months?
Pesquet: It’s not easy for us being up there, and it’s not easy for the people we leave behind. The toughest thing is being deprived of your loved ones, and also being constantly worried that if something happens to them, you cannot help them. I think it’s the nightmare of all the astronauts, that something happens to their families on Earth while they’re away.
I believe there’s an element of selfishness in me going to space because it’s a fantastic magical experience. But I also firmly believe that there’s a hugely positive impact on society in general because of what we do; because of the research, because of the international cooperation. So I think we have to do it even if there’s a price to pay. It’s not easy, but I think it’s a good thing to do.
CNN: As a climate advocate, do you think about the environmental cost of space travel?
Pesquet: As an astronaut, you witness the fragility of planet Earth, while simultaneously thinking, “wait a minute, what is my impact on all this? I’m going to space in a rocket, how does that impact the environment?”
Yes, space travel produces some CO2, and it is not entirely environmentally friendly. But I think you have to take into account the positives with the negatives. There are so few rocket launches that compared to aviation, cars or other industries, our impact is negligible. We need activity in space to get satellite research done. This benefits the planet a lot. So space travel is a necessary evil.
CNN: Since you have returned from the ISS, what are your hopes for the future protection of our planet?
Pesquet: If we set ourselves on the right path, there’s nothing we cannot do. We built this unbelievable facility in space for good reasons. We’re using it every day, in peaceful cooperation between countries that were not always friends. So if we can transfer that model to the way we deal with the environment on Earth, I think we’ll get there.
We’re creative enough, we have the technology and we have the will. So I’m optimistic for the future. If we can make a space station fly, then we can save the planet.

Here’s how Helene and other storms dumped a whopping 40 trillion gallons of rain on the South

Published

 on

 

More than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it — an unheard of amount of water that has stunned experts.

That’s enough to fill the Dallas Cowboys’ stadium 51,000 times, or Lake Tahoe just once. If it was concentrated just on the state of North Carolina that much water would be 3.5 feet deep (more than 1 meter). It’s enough to fill more than 60 million Olympic-size swimming pools.

“That’s an astronomical amount of precipitation,” said Ed Clark, head of the National Oceanic and Atmospheric Administration’s National Water Center in Tuscaloosa, Alabama. “I have not seen something in my 25 years of working at the weather service that is this geographically large of an extent and the sheer volume of water that fell from the sky.”

The flood damage from the rain is apocalyptic, meteorologists said. More than 100 people are dead, according to officials.

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just Georgia, Tennessee, the Carolinas and Florida from Hurricane Helene.

Clark did the calculations independently and said the 40 trillion gallon figure (151 trillion liters) is about right and, if anything, conservative. Maue said maybe 1 to 2 trillion more gallons of rain had fallen, much if it in Virginia, since his calculations.

Clark, who spends much of his work on issues of shrinking western water supplies, said to put the amount of rain in perspective, it’s more than twice the combined amount of water stored by two key Colorado River basin reservoirs: Lake Powell and Lake Mead.

Several meteorologists said this was a combination of two, maybe three storm systems. Before Helene struck, rain had fallen heavily for days because a low pressure system had “cut off” from the jet stream — which moves weather systems along west to east — and stalled over the Southeast. That funneled plenty of warm water from the Gulf of Mexico. And a storm that fell just short of named status parked along North Carolina’s Atlantic coast, dumping as much as 20 inches of rain, said North Carolina state climatologist Kathie Dello.

Then add Helene, one of the largest storms in the last couple decades and one that held plenty of rain because it was young and moved fast before it hit the Appalachians, said University of Albany hurricane expert Kristen Corbosiero.

“It was not just a perfect storm, but it was a combination of multiple storms that that led to the enormous amount of rain,” Maue said. “That collected at high elevation, we’re talking 3,000 to 6000 feet. And when you drop trillions of gallons on a mountain, that has to go down.”

The fact that these storms hit the mountains made everything worse, and not just because of runoff. The interaction between the mountains and the storm systems wrings more moisture out of the air, Clark, Maue and Corbosiero said.

North Carolina weather officials said their top measurement total was 31.33 inches in the tiny town of Busick. Mount Mitchell also got more than 2 feet of rainfall.

Before 2017’s Hurricane Harvey, “I said to our colleagues, you know, I never thought in my career that we would measure rainfall in feet,” Clark said. “And after Harvey, Florence, the more isolated events in eastern Kentucky, portions of South Dakota. We’re seeing events year in and year out where we are measuring rainfall in feet.”

Storms are getting wetter as the climate change s, said Corbosiero and Dello. A basic law of physics says the air holds nearly 4% more moisture for every degree Fahrenheit warmer (7% for every degree Celsius) and the world has warmed more than 2 degrees (1.2 degrees Celsius) since pre-industrial times.

Corbosiero said meteorologists are vigorously debating how much of Helene is due to worsening climate change and how much is random.

For Dello, the “fingerprints of climate change” were clear.

“We’ve seen tropical storm impacts in western North Carolina. But these storms are wetter and these storms are warmer. And there would have been a time when a tropical storm would have been heading toward North Carolina and would have caused some rain and some damage, but not apocalyptic destruction. ”

‘Big Sam’: Paleontologists unearth giant skull of Pachyrhinosaurus in Alberta

Published

 on

 

It’s a dinosaur that roamed Alberta’s badlands more than 70 million years ago, sporting a big, bumpy, bony head the size of a baby elephant.

On Wednesday, paleontologists near Grande Prairie pulled its 272-kilogram skull from the ground.

They call it “Big Sam.”

The adult Pachyrhinosaurus is the second plant-eating dinosaur to be unearthed from a dense bonebed belonging to a herd that died together on the edge of a valley that now sits 450 kilometres northwest of Edmonton.

It didn’t die alone.

“We have hundreds of juvenile bones in the bonebed, so we know that there are many babies and some adults among all of the big adults,” Emily Bamforth, a paleontologist with the nearby Philip J. Currie Dinosaur Museum, said in an interview on the way to the dig site.

She described the horned Pachyrhinosaurus as “the smaller, older cousin of the triceratops.”

“This species of dinosaur is endemic to the Grand Prairie area, so it’s found here and nowhere else in the world. They are … kind of about the size of an Indian elephant and a rhino,” she added.

The head alone, she said, is about the size of a baby elephant.

The discovery was a long time coming.

The bonebed was first discovered by a high school teacher out for a walk about 50 years ago. It took the teacher a decade to get anyone from southern Alberta to come to take a look.

“At the time, sort of in the ’70s and ’80s, paleontology in northern Alberta was virtually unknown,” said Bamforth.

When paleontogists eventually got to the site, Bamforth said, they learned “it’s actually one of the densest dinosaur bonebeds in North America.”

“It contains about 100 to 300 bones per square metre,” she said.

Paleontologists have been at the site sporadically ever since, combing through bones belonging to turtles, dinosaurs and lizards. Sixteen years ago, they discovered a large skull of an approximately 30-year-old Pachyrhinosaurus, which is now at the museum.

About a year ago, they found the second adult: Big Sam.

Bamforth said both dinosaurs are believed to have been the elders in the herd.

“Their distinguishing feature is that, instead of having a horn on their nose like a triceratops, they had this big, bony bump called a boss. And they have big, bony bumps over their eyes as well,” she said.

“It makes them look a little strange. It’s the one dinosaur that if you find it, it’s the only possible thing it can be.”

The genders of the two adults are unknown.

Bamforth said the extraction was difficult because Big Sam was intertwined in a cluster of about 300 other bones.

The skull was found upside down, “as if the animal was lying on its back,” but was well preserved, she said.

She said the excavation process involved putting plaster on the skull and wooden planks around if for stability. From there, it was lifted out — very carefully — with a crane, and was to be shipped on a trolley to the museum for study.

“I have extracted skulls in the past. This is probably the biggest one I’ve ever done though,” said Bamforth.

“It’s pretty exciting.”

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
