Ice in Antarctica

We know that ice started to form in Antarctica some 34 million years ago while that did not happen in the Northern Hemisphere until about 20 million years ago - why? Elevation! GHG concentrations and thus temperatures slowly declined over the last several 10s of millions of years. At the same time, Antarctica saw tectonic uplift and at some point the rising land and falling temperatures meant that the glaciation level dropped to below the land elevation and it became possible to snow to persist year-around - cool!

Well-done Cleo! This video offers great context centered around three important dates or decision points: 1959, 1987, and 2026. Watch the last minute or whole thing:

 

AI & Data Viz

Or, to make it simpler: Making charts with AI (as opposed doing it yourself with MS Excel). Good stuff here from the folks at Storytelling With Data: https://www.storytellingwithdata.com/ai-data-storytelling

485 Million Years!

Good WP article & PBS Terra video!

• The REAL STORY of Climate Skeptics New Favorite Graph
• Scientists have captured Earth’s climate over the last 485 million years. Here’s the surprising place we stand now.

What are the take-home messages? CO2 is the main climate driver and climate change is normal. Yep, but: the climate change we are measuring today is a) much faster than anything over the last 485 million years and b) caused by humans, not by nature.

Lean & AI

Lean is the hip thing in math these days, especially in connection with AI. That's all I know, but here's more: ‘It is incredible’: How AI is transforming mathematics
