Climate Economics and Finance are completely ignored by the private sector based financial sector and other economic sector participants.
The climate-related financial disclosures aka #TFCDs and other nudges, being promoted by different global financial institutions and economic blocs, have not yet reached many countries.
Most banks and other firms are now investing in climate-related risk modelling and stress testing.
Central Banks in the Third World should ask licensed banks to do the same to promote a Green, Clean, and Care Economy.

Con gusto. New links to observe how the Arctic sea ice (#BOE) and Greenland ice sheet (#GIS) export fresh cold water to the Atlantic. How long until the AMOC tips and shuts down, accelerating warming and sea level rise?…
Hansen 2016…
Monsoons. Note what mental contortions the authors perform under the absurd @Peters_Glen @hausfath @MLiebreich crusade against #RCP85. Have we stopped this nonsense yet?…

@climate_ice, is GIS subglacial methane cycling accelerating?…
@Peters_Glen @hausfath @MLiebreich @climate_ice This really isn't hard. Please focus and do science that matters if you can. We need your support.

Today marks 20 yrs of #remission from #Crohns. For some #IBD patients, remission feels like an elusive thing. I get it, I’ve had my share of time in the #ICU. I’m extremely fortunate that #Remicade has worked this long. Many people must switch meds to find a lasting solution. 1/n
The last 20 yrs haven’t come w/o complications. A sustained high quality of life was worth the trade offs that come with #biologics. I lived with recurrent infections and a #cancer diagnosis. Was it challenging? Yes. Was it better than living with flares? Absolutely. 2/n
There isn’t a day that I don’t think of those that weren’t as lucky. Alex Davidson, Ty Redler, Lacey Conners and Lindsey D’Ercole were younger than me and have since passed from IBD complications. In spite of some survivor’s guilt, I do my best to keep their memory alive.💜 3/n

My new map shows the population change (%) between 2017 and 2020, using Eurostat data

#population #Demography #depopulation #europe #RStats #maps #dataviz #gis Image
One pattern is visible for Central & Eastern European countries: apart from major towns the rest has a negative population growth
🇮🇹Italy has a negative population growth in nearly every corner of the country including Rome 😬

3D maps can look complex & difficult to make…
Here are 12 humans who proved to me that 3D is not out of reach:
Different tools, many styles... all fantastic: 1/14🧵 #dataviz #3dmaps #gis
Graig Taylor | @CraigTaylorViz: Legendary 3D maps made in #Cinema4D. Not only gorgeous maps but also perfectly animated worlds. His maps cannot be unseen. Clearly a #3dmap guru. #GIS #dataviz 2/14
Tyler Morgan-Wall |@tylermorganwall devlpr of the incredible R libraries #rayshader and #rayrender adding features & tutorials for free at an incredible pace: a *true treasure* for the #rstats #3dmaps & #3dviz world. A must-follow for 3d #dataviz. 3/14 🧵

Anyone wants to get started or has used #rspatial and learned from tutorials/courses using packages such as {rgdal} {rgeos} {sp} {raster}? Are you getting used to them already? You might want to reconsider 🤔
🧵 1/n
For the past few months the R Spatial community of developers and active users has been dealing with the news of the retirement of {rgdal} & {rgeos}
🧵 2/n
For {sp} is a similar story, although still getting maintenance, a migration to {sf} should be mostly preferred for any new developments and implementations

Ihr habt gesprochen – zwei Drittel meiner Open-Data-Bubble finden, dass WMS-Kartenservices durchaus als #OpenData anzusehen sind. Vielen Dank! #gis 🗺️ 1/12
Der ursprüngliche Anlass zu der Umfrage war die Frage, ob bestimmte WMSe in aus dem Portal entfernt werden sollten, weil es sich bei ihnen nicht um Open Data im eigentlichen Sinne (maschinenlesbar, strukturiert) handelt. 2/12
(Übrigens stehen die allermeisten WMSe im Berliner Datenportal nicht für sich, sondern haben mind. einen WFS, der sie spiegelt.) 2.5/12

BK Kurz bekommt heute in München den „Medienfreiheitspreis“ eines konservativen deutschen Verlags.
Zu Unrecht, meint ⁦@POLITICOEurope⁩:…
Zur Medienpolitik von Kurz meint der Stifter des „Freiheitspreis der Medien“ Wolfram Weimar:
In dem @POLITICOEurope-Artikel heißt es übr. zum ORF: “‘There have been critical phases in the past, but it has never been as bad as it is now,‘ said a senior ORF journalist.“
Das sehe ich nicht so. Das war unter Türkis-Blau tats. schlimmer.

1/_ Interactive #GIS map showing risk of #DebisFlow for wildland fires. For the legend and to get the most benefit from the map, please click “Map tips” in upper left corner. To search on address click Menu > Search. #CAwx

Open #GISsurfer map: Image
2/_ The map opens at the #CZULightningComplex. You can pan the map to other 2020 fires and see the same type of data. Be patient! The map might be slow to refresh. It depends in part on how much other work the GIS server is doing.
3/_ The map can display the risk of debris flow for fires back to 2017. Here is one way to make a map to see the risk of debris flow for a fire prior to 2020:
A. Click the basemap button and look under the “Overlays” heading
B. Click “Turn off all overlays”

1/14 I have been volunteering to produce online wildland fire maps for about the last 10 years. This is a multi-part tweet to help people understand satellite hotspot data for wildland fires.
2/14 The #1 thing to know is that any fire data you see on maps is **not real time**. After a satellite pass it takes NASA ~3 hours to process the raw data before it can be displayed on any map.
3/14 Since data you see via an online map is **not real time**, never rely on any map (or anything else) to ignore an order to evacuate. The professionals that make decisions which areas must evacuate have more information than is available to you.

Jeg lovede i går at fortælle mere om, hvordan mine data fra databasen skal analyseres. Og fordi landskabet på tangen er så foranderligt i 1700- og 1800-tallet, så spiller rummelighed en aktiv del af forståelsen af disse samfund. /CA 1-18. #spatialhumanities #GIS
Derfor har jeg valgt at anvende GIS som et analytisk værktøj. GIS bliver efterhånden brugt i mange sammenhænge og inden for flere og flere videnskaber. Jeg er heller ikke den første til at bruge det inden for historievidenskaben, selvom det er et relativt nyt felt. 2-18. #HGIS
En af fordelene ved GIS er, at du visuelt kan håndtere en langt større mængde data med en rummelig dimension, og netop det visuelle kan være med til at afsløre mønstre og sammenhænge, som ellers ikke ville være blevet klarlagt ved at se på det enkelte individ. /CA 3-18.

The first article first-authored by my BSc, MSc (and quickly PhD) student @LDaumantas is out!…
By combining insights from #archeology, #paleobiology, #GIS , #geostatistics and #Machine_learning we revealed the dynamics of ancient human settlement rules 1/n
Extending the classical #cliodynamics approach advocated by @Peter_Turchin we tracked the dynamics of evolving spatial interactions of human settlements with geological/geomorphic factors while testing against spatial null models 2/n
Finally, we found that model significance (difference with null models) increased through time while their performance decreased. We explained this pattern as an increase in determinism of settlements, paired with the increase in complexity and specificity of rules 3/n

2/3 Map has lots of #GIS overlays you can turn on/off/restack. Need help? Click "Map tips" upper left corner. There is also a ‘Legend’ link in the upper left corner.
3/3 Note! The map is still showing some ‘false positive’ satellite hotspots. That problem should fix itself mid-morning. For more information, click “Map tips” and read about the data.

I often get asked "What degree should I get if I want to pursue GIS?" They are often surprised when I don't point towards a traditional #GIS degree. In my opinion a cross disciplinary approach to GIS is highly marketable and useful, I think most GIS practitioners would agree.
One of the best things I did was chose #landscapearchitecture as my undergraduate program @WestVirginiaU. At it's foundation, Landscape Architecture (LA) draws on both art and science to solve problems. Sounds a lot like map making to me! Now, I didn't start out with GIS in mind.
Early on in the program you learn about space and place. More importantly, how to conceptualize/visualize your design process. LA has a lot of cross-over between many disciplines such as Graphic Design, Engineering, Planning, Project Management, and of course GIS!

I am always nervous before each and every podcast interview.

Not because I am afraid of working/ learning in public but because want to be respectful of my guest's time and create content that will give the podcast audience value.

Here are the 10 most popular podcast episodes!

1/7 Each day #JohnsHopkins publishes *cumulative* counts of #COVID19 cases for each county in the USA. As a public service I wrote code to convert that cumulative count data into *daily* counts for all USA counties. #CovidData #Covid19Data
2/7 This daily count data is in one csv file per month. There is one set of files with daily *case* counts and another set of files with daily *death* counts. Anyone can download and use this data. The only limitation is no commercial use.
3/7 These files include a latitude longitude centroid for each county and will be easy to import into spreadsheet or #GIS software. Each night the count of new #COVID cases for the prior day is added to the current monthly csv file.

This photo is meaningful to my career as a planetary scientist even though I’m not affiliated with this mission in any way, and this is a short thread why. I’m quickly learning how different my experience has been and prob why it’s necessary to yell about it to the internet. 1/9
This photo was taken and released roughly 5 years ago, mid-July 2015. The first time I saw this, I remember pulling up the front page of reddit while waiting at the bank to ask them to forgive an overdraft fee because I was a really, really broke undergrad student. 2/9
I remember reading the reddit comments about what a large team it took to make this photo happen. Hours of planning, tens of people involved from all over the country. “More than 5 people total, got it.” I had no idea what it was like to plan and execute photos like this. 3/9
