Scientists have made a groundbreaking discovery by tracking the speed and direction of glaciers around the world, revealing that these massive ice masses are changing at an unprecedented rate. For the first time, researchers have created a global dataset that analyzes over 36 million satellite image pairs - including decades of Landsat data - to track the seasonal "pulse" of every major glacier on Earth.
Using Landsat data, scientists were able to measure the movement of glaciers, revealing that seasonal changes in glacier flow are becoming more pronounced as the planet warms. The study found that when annual maximum temperatures exceed freezing point, seasonal variability becomes prominent in glacier flow, and its amplitude increases with each degree of warming above that threshold.
The researchers combined Landsat data with radar data to track ice velocity, allowing them to reconstruct a complete timeline of glacier flow. This approach made it possible to isolate universal relationships driving seasonal fluctuations in glacier flow globally.
However, the study highlights regional and glacier-type differences in glacier dynamics, making it crucial to understand these global variations. By analyzing nearly every glacier on Earth, researchers identified general patterns that suggest temperature plays a key role in shaping glacier response to external forces like meltwater lubricating bedrock or changes in frontal melting.
The findings of this research also have significant implications for future studies and the potential impacts of remote sensing technology advancements. With Landsat 9 data already being incorporated into the ITS_LIVE project, researchers are looking forward to exploring new insights on glacier mechanics and seeing what breakthroughs come from the wider scientific community exploring this open data.
The use of Landsat data in tracking glaciers has several advantages, including near-exact repeat orbits, nadir viewing, and stable instrument geometry. However, future sensor improvements offer a trade-off: increased spatial resolution allows for higher surface feature tracking but may also increase error rates due to accumulated displacement signals. Increased temporal frequency can reduce data gaps caused by surface changes, but it also risks increasing error rates.
This study provides new insights into the dynamic behavior of glaciers and highlights the importance of understanding regional and glacier-type differences in glacier dynamics.

I'm literally blown away by this discovery!!! Scientists tracking glaciers for decades just now realized that they're changing at an unprecedented rate 
Like, our planet is warming up and it's affecting those massive ice masses in ways we never thought possible 
. It's not just about climate change, it's about understanding how our actions impact these incredible natural wonders 
. And I love that this study is like, totally open to the scientific community, so more people can get on board and help us figure out what's going on 
scientists are finally using sat imagery to track glacial movement & its shocking how fast they're melting 
. like, we already knew it was bad, but 36 million image pairs is a wild amount of data 
. now that they've got this global dataset, we can see patterns emerging & it's actually kinda scary 
. glaciers are like, super sensitive to temp changes & it's not just about the temp itself, but how it affects meltwater & bedrock 
. what's next? gonna be a wild ride exploring these new findings 
... But apparently they're moving way faster than we thought! It's like, scientists looked at old satellite pictures (Landsat data) of these glaciers and tracked how fast and which direction they were moving over time. And guess what? They found out that the Earth is getting warmer and it's making glaciers change more rapidly.
️... if it gets warmer, the ice gets slushy and harder to control. That's basically what's happening with glaciers now. The warmer temperatures are causing them to melt and move faster. It's pretty cool (get it?) that scientists were able to figure out this stuff using satellite pictures.
... so we need to understand these differences to know how they're going to change in the future. Scientists are already working with new satellite tech that's gonna give us even more insights into glacier behavior. Fingers crossed we can learn from this and make some progress!
. what's trippy is how temperature plays a huge role in shaping glaciers, like, it's not just about melting ice, it's also about the bedrock and stuff. anyway, can't wait to see where this research takes us 
like what is happening to our planet?! We're basically running out of time to figure out how to save these ice giants and our planet with them... it's all so interconnected, you know? The science behind this study is literally mind-blowing 
- they used satellite images to track the movement of glaciers over decades and created this huge dataset that shows us the pulse of every major glacier on Earth. It's crazy how much info we can get from just analyzing Landsat data 
But seriously, it makes total sense that global warming would cause them to speed up. I mean, ice is melting and stuff... it's not rocket science or anything 
.
. What's really striking is how temperature plays a big role in it all - the more it warms, the more pronounced the seasonal changes become. Makes sense, right? 
But what I find even more interesting is how these advancements could lead to breakthroughs with remote sensing tech. Can't wait to see what comes next! 
about this discovery! Scientists finally have a way to track glaciers on a global scale, which means we can actually see how fast they're melting 
36 million satellite image pairs is insane! 1 degree warming above freezing point increases seasonal variability by 20-30% 
i'm low-key amazed we didn't know this already, the science is out there and we're still learning 
! I mean, scientists are actually tracking glaciers around the world like they're athletes competing in some kind of ice-racing championship! And the best part is, they've created a global dataset that's gonna help us understand how these massive ice masses are changing at an unprecedented rate... which, let's be real, is not exactly what we want to see happening. BUT, on the bright side, this research is gonna give us some awesome insights into glacier dynamics and how temperature plays a key role in shaping their response to external forces. Plus, it's all thanks to satellite image pairs - talk about tech advancements 
...anyway, can't wait to see what new breakthroughs come from this open data and ITS_LIVE project! 
& it's like, totally mind blown! scientists found out that glaciers are changin at an unprecedented rate cuz the planet is gettin warmer 
. they analyzed over 36 million satellite image pairs & created a global dataset that shows us how temperature plays a key role in shapin glacier response to external forces 
& the fact dat researchers r lookin forward 2 explorin new insights on glacier mechanics 
They're always melting, growing, moving... it's like they're trying to outdo each other in some sort of frozen game show. But seriously, can we please take care of these ice giants? We've got a dataset that's tracking all 36 million satellite image pairs and it's showing us that glaciers are changing at an unprecedented rate. I mean, who needs that much ice melt, right?
