So, we met an astronaut.
No kidding; it's even more exiting than meeting Leonardo DiCaprio. After we registered and got our bearings within the venue, the first place we wandered was the zone where many different countries get to put up different displays and host small side events (and also give away free stuff!). We found the U.S. Pavilion, and the main organization presenting there all week is NASA.
One of our students, Jade, had met employee of NASA Daniel Irwin on her way to our apartment the night she flew in; he was fluent in Spanish and they were staying in the same area, so he helped her arrive safely (and we couldn’t be more thankful for that). Luckily, when we went to the pavilion, he was there – with his good friend, the astronaut of fifteen years, Dr. Piers Sellers.
We got to talk to them both before any official presentations began. When speaking of the Hyperwall (pictured below of some not-so-impressive photos I took while we were there… you should really check out the NASA website to see amazing photos and videos that they simulate on the Hyperwall), Dr. Sellers looked at us with a clever smirk on his face and proudly proclaimed, “oh, wait until you see it. It’s better than Interstellar.”
When the presentation began, we could only see how right he was. It blew us all away. Eyes wide and up in front, it was almost too much to take in at once.
Most of the presentation comprised of data that was gathered purely via NASA satellites. In this single presentation, they went over how they could compile data into comprehensive videos and images of the salination levels in the oceans, the change in ocean currents, the ice coverage globally, fires that happen, and perhaps most poetically: they can show us how the earth breathes.
(See the video clip of this segment here: link.)
Think about it: as spring comes for the Northern Hemisphere, our trees sprout their leaves and our flowers peek up their sleepy heads. They breathe in carbon dioxide, taking it out of the atmosphere; and when it’s winter in the Northern Hemisphere, it’s summer down in the Southern. Earth breathes in carbon dioxide in the summer, and exhales it in the winter. Like you or me, Mother Earth breathes.
Consider this in a way you might not have before. Consider the Earth as one functioning unit; as a body. And this is why climate change is so important; this is why we care. This system is fragile, and we are disturbing this gentle balance.
Luckily, NASA (and other organizations) has the technology to not only compile data into pretty videos, but they also have the ability to model how certain ecosystems will react to climate change. These are not guesses, or cartoons; they are realistic models built with copious amounts of data.
The scary part, though? With just a 4 degree Celsius change, we would be living in a world where we can’t make predictions. A change of just 4 degrees Celsius would cause a world so different from the one we’re currently in, none of our current, real-world data would be applicable.
And studies show we’re going to have to make some serious, serious changes if we want to stop at 2 degrees Celsius.
It’s hard to think of why we should care about climate change in a place like America. After all, climate change isn’t affecting us, right?
The sea level has already risen three inches. This might not sound like a lot, but this is across the entire planet. There’s more water on our planet than there is land, and enough has melted to cause it all, on average, to rise three inches. People in Miami, Florida are already having problems with sea water getting into their plumbing and sewage systems. Climate change is right on our door step, and she’s knocking.
However, with proper use of the models that NASA and other organizations produce—whether they are actual compositions of data or realistic models—it can help us avoid catastrophic disasters. For example, NASA was able to predict the movement of Hurricane Sandy of 2012 that saved the lives of thousands of people in New Jersey, because they knew they had to evacuate.
Beyond that, in the 1980s, when Chlorofluorocarbons (CFCs) were banned by the Montreal Protocol in order to minimize the growth of the Ozone hole, we avoided a disasterous world.
What kind of world?
Let NASA show you.
Let’s hope that our world never becomes like the one on the right. We will not become a projection. We will fix our reality.
