The Timeline of Earth through Ice Cores
With more climate data regularly available to scientists, we know more about our environment than ever before. But, there are just so many ways to use the data, and it is important that it is used to bring awareness to imminent danger our world is in.
Of course, we need to remember that climate change is not an issue for tomorrow. We are living it now. And, if we want to save the world, it would be helpful to find ways to manage it now.
A team of scientists from MIT published a new paper this week that presents an innovative approach to help the environment.
The paper uses ice cores to measure temperature from ancient times. The idea is to look back ten thousand years, and create a record of how the environment evolved. Ice has frozen layer by layer over millions of years, and each layer has different materials in it depending on the era. This provides a great way to learn about the era, or when a specific layer of ice was on the surface. This allows scientists to understand not only the environmental changes of the past, but also the people and animals that lived at the time
The team used the data that was recorded back in the 1970s. Since then, many scientists have focused their attention on finding ways to store the data. But while these are useful for scientists, they aren’t helpful for us in today’s day to day lives.
The team used a novel approach that allows them to create a record of temperatures with a 3D printer. They deposited a thin material, called a nano pillow, in water and the area dried out. After that, they used a technique called evaporative cooling to create a thin film of water around the core. The team used a novel method of cooling their cores by melting water with a cooling chip.
The team found that the device can be scaled up. In fact, they discovered that by using a microchip, they could make a thermal radiometer.
“You can scale this experiment to the world,” says Harry M. Brumley, one of the researchers on the paper, in an interview with the MIT Technology Review.
The study was published in the Journal of Chemical Technology and Biotechnology.
