Warsaw in 3D

This is actually pretty cool: Warsaw in 3D

Nothing too special here - we have seen these kind of 3D cities before. What is cool is to play around with the dates & times & see how the shadows change with changing sun angles over the course of the day or year.

The Local Wikipedia

This is fun: Local Wikipedia is Wikipedia, but only for things a half hour walk from you! Try it out @ https://edjefferson.com/localwiki/.

The Becket Potholes

The western side of Gobble Mountain in East Becket (MA) apparently offers some actual glacial potholes (as opposed to the fluvial ones  in Shelburne Falls). I wish one of these sources would contain a proper map that one could use to find them, but the pics are good!

    The 2026/2027 'Super' El Nino

    Fact: the current SSTs in the eastern tropical Pacific are about 3 deg C higher than normal and that's more than 1 deg C warmer than the powerful 1997 & 2015 El Ninos. So, what can we expect?
    1. Droughts in southern Africa (e.g. Malawi, South Africa, etc.).
    2. Dry conditions & wild fires in Indonesia, Malaysia, etc.
    3. Dry conditions & wild fires in the Amazon region.
    4. El Nino years, and especially the year after an El Nino year, are generally hotter on a global scale - so expect 2027 to be anothe record year.

    This sea surface elevation comparison (1997 vs 2026 El Nino) from NASA is great: https://science.nasa.gov/earth/earth-observatory/el-nino-then-and-now/

    Sealevel Rise & Lower

    This one is actually pretty cool: https://slidingshores.com/
    Now, the amount of rise & lower is getting pretty crazy & is way more than anything that could happen on Earth, but a) it's fun and b) this is the only 'animation' that I know of where you can actually lower sealevel to demonstrate conditions say during the LGM.

    For a more 'realistic' sea level rise visualization: consider the Coastal Risk Finder.
