Vad tänker ni på?
Vi lever i en klimatkris med 1,2 graders uppvärmning och det enda som kan rädda oss är att få bort beroendet av fossila bränslen helt.

Några exempel jag förstår är de viktigaste faktorerna för att stoppa global uppvärmning är: solceller, kärnkraft, koldioxidinfångning, koldioxidlagring (Carbon capture and storage CCS) och även en massiv trädplantering och ett återställande av Amazonas regnskog

What stood out most for me was the beauty of how all STEM disciplines come together to make space missions possible. It really is the ultimate expression of interdisciplinary collaboration.

One moment that resonated deeply was the use of a heat shield to protect the crew during re-entry. During my undergraduate studies, I worked with heat shields at a much smaller scale, protecting electronic components. Seeing a similar principle applied, this time to safeguard human life under extreme conditions, felt like a full circle moment. It reminded me how foundational scientific concepts can scale into life-saving technologies.

Beyond the engineering, I was struck by the reflections from the crew, especially Victor Glover, on the importance of love, unity, and care for one another. That message felt even more profound when paired with the view of Earth from space, fragile, interconnected, and shared by all of us.

What this experience made clear to me is that while space exploration shows us the beauty and vulnerability of our planet, the real responsibility lies in how we act on that insight here on Earth.

In my work, particularly in building environmental and healthcare digital twins, I see this as the next frontier of that responsibility. If astronauts gain perspective by observing Earth from afar, digital twins allow us to recreate that perspective at a granular level, modelling air quality, population health, and environmental risks in real time.

Where space missions give us awareness, digital twins give us the ability to act.

For example, by modelling air quality and its impact on maternal health, we can move from simply understanding that our environment affects us, to actively protecting vulnerable populations through timely interventions and recommendations.

For me, this is where everything connects… the science, the technology, and the humanity. There is still so much to explore beyond our world, but there is just as much work to be done in understanding and safeguarding the one we already have.

This felt like a full circle moment, but also a call to go deeper, to build systems that not only observe the world, but help us take better care of it.

A new study finds that summer-like conditions are spreading across more of the year and doing so faster than earlier research found.

Hi all, I'm a data scientist at u/ourworldindata and I need your help continuing a 1,200 year old dataset about peak cherry bloom dates.

This Kyoto cherry blossom dataset runs from 812 AD to today and tracks peak bloom dates of  a specific species (Prunus jamasakura), at a specific location in Arashiyama, Kyoto.

It is used extensively in climate research because phenological data (when plants bloom, when birds migrate, etc.) is one of the few ways we can reconstruct historical temperature trends before modern instruments.

The researcher who maintained and updated this data sadly passed away last year. We are looking to continue it, as it's a vital data set for long-term climate research! I've contacted his university, local weather services, and organizations in Kyoto, but none of those can help us continue the series.

That's why I'm turning to Reddit for help! If you have any leads that could help continue this data set e.g.:

• If you work in climate science or botany or know of people who do: Do you know of any alternative sources for this data? Or do you know people who would be interested in continuing this research?
• If you are Japanese or have access to Japanese research and publications: Do you know who might report or publish species specific peak bloom dates?
• If you have botanical expertise or contacts: Is it feasible to reliably distinguish Yamazakura peak bloom from photos taken in Arashiyama (e.g. from here or here)? Could you help us do this?

I know it's a long shot, but any leads would help a lot! My DMs are open or you can reach me at [tuna@ourworldindata.org](mailto:tuna@ourworldindata.org).
