@exconomist @LudoGazze This would be my approach, unfortunately it would take quite a bit of processing. I’ve done it for calculating my own heating/cooling degree days metrics , but don’t know of a public source for this sort of measure. Feel free to reach out for more details.

Super interesting and creative work!

Tree planting is widely popular w/ programs from the Sahel to South Korea – but can it lead to *local* climate change?

@florian_grosset @ctaylor463 and I study this in a new WP "Rain follows the forest: Land use policy, climate change, and adaptation" https://t.co/cqHDCFfgYG 1/8

@MeganKonar I started grad school wanting to pursue water economics but the data just wasn’t there for the questions I had. Makes me happy that this kind of resource is there for today’s young researchers!

[Chris Mihiar @chris_mihiar]

Really impressive work here and public data too!

[Megan Konar @MeganKonar]

How much water does each crop use?

We estimate irrigation for each crop in the United States, by county, year, & water source.

Our database of ~2.5 million data points is freely available.

More than 61 million people consume water from the eastern region's forested watersheds - and the majority of those forests are owned by individuals & families! Raise a glass to our family forest owners! #cheers #NationalWaterQualityMonth

Many people new to machine learning have no idea that labeling data is a problem they need to think about.

To be clear: "labeled datasets" aren't a thing in the real world.

Here is an excellent approach to getting past this problem:

Here is my #viz for the #TidyTuesday challenge - week 24. This one is about the historical drought conditions (1895 – 2022) in the U.S. contiguous.

Opinion piece: To stymie #deforestation, we need to focus on ending gross, not net deforestation. It’s a crucial distinction omitted from the recent #GlasgowDeclaration on #forests: https://t.co/IggWHkReB0 #ClimateChange #COP26 #emissions

Healthy forests don’t happen by chance.

The 176 million acres of forest in the Northeast & Midwest provide clean water, wildlife habitat, recreation, jobs, forest products & carbon storage.

Read about how we are working together to ensure these benefits

For millennia, humans have used more and more land for agriculture, taking over wild habitats.

But, we are at a unique point in history: agricultural land use has peaked.

The pandemic triggered a worker shortage in many areas. A @usfs_srs scientist explains how the pandemic limited the availability of wood products, such as softwood lumber & structural panels used to build homes. https://t.co/4hPzOVhEei 📷 Licensed Getty image
