Als Ergänzung: Die #ERA5 -Daten sind über eine #API erreichbar, und in unserer lokalen AG Klimaschutz hat auch jemand Skripte zum Auslesen entwickelt.

Theoretisch sollte es also für die #Grünen möglich sein, mit relativ überschaubaren Aufwand lokalisierte Klimadaten für #Kommunalwahlen im großen Stil zu erzeugen.

Und für Umweltschutz-Verbände wie #BUND , #NABU etc. wäre das vielleicht auch interessant.

#Klimawandel

In #Oldenburg sind bald #Kommunalwahlen .

Und da wir #Grünen natürlich über den #Klimawandel reden wollen, haben wir uns diesmal was ausgedacht: Wir haben historische Wetterdaten aus dem #ERA5 - Datensatz _für Oldenburg_ ausgewertet, und die grafisch dargestellt.

Wir dachten uns, daß "globaler Klimawandel" etwas abstrakt ist, aber wenn man sieht, wie sich das Klima hier am eigenen Ort verändert haben, dann nimmt man das vieleicht eher als relevant war.

Und Temperaturdaten sind nur eine Möglichkeit von vielen - da gibt es Daten zu Niederschlägen, Windgeschwindigkeit, Bodenfeuchtigkeit, und viel mehr. Ich denke, andere Ortsgruppen der Grünen könnten vielleicht auch etwas mit diesen Daten machen.

Was meint ihr?

Scientists See More Vegetation In The Himalayas - But It Is Not Good News, Because That Extra “Green” Can Disrupt Water, Snow, And High-Mountain Biodiversity | Plants Growing Higher Across Himalaya As Climate Warms

“For years, the biggest climate warning from the Himalaya was easy to picture because glaciers were shrinking on the roof of Asia. Now, researchers are pointing to a quieter signal, one that can look almost harmless from a distance. The mountains are getting greener.
New research [link above] shows alpine vegetation moving higher across six Himalayan regions from 1999 to 2022, pushed in part by warming and reduced snow depth. That might sound like nature recovering, but in this fragile landscape, more plant cover at extreme heights may change how snow is stored, how water runs downhill, and how rivers behave for communities far below…”

Carlo Buontempo, Director of the Copernicus Climate Change Service (C3S) @ECMWF emphasises how the global average temperature exceeded 1.5°C over a three-year period (2023–2025) – the first time in the #ERA5 record – bringing us closer to the Paris Agreement threshold.

Question: Is anyone here familiar with the #ERA5 dataset used for the climate data at #OpenMeteo ?

I intend to use it for the local elections for my local #Green Party chapter, by visualizing local climatic changes. And I need to be ready for arguments on the lines of:

"This data is interpolated, therefore not real and thus can be dismissed!"

Thus, if there are any good, accessible explanations that summarize how the dataset was created, I would appreciate it. Bonus points if they are in German!

Die #Klimakrise trifft die #Welt:

Der August 2025 war weltweit der drittwärmste seit Beginn der Aufzeichnungen.

Laut #Copernicus-#Klimadaten lag die globale Durchschnittstemperatur bei 16,60 °C und damit 0,49 °C über dem Schnitt von 1991–2020. Im Vergleich zum vorindustriellen Niveau beträgt der Anstieg 1,29 °C.

Besonders #Europa erlebte zwischen dem 8. und 18. August eine ausgeprägte #Hitzewelle mit deutlichen Temperaturabweichungen.

I've been following the news about discontinuing #NOAA data with sadness and apprehension. This is all very messed up.

Currently I rely heavily on #nasapower #gpm and #chirps data for monitoring agroclimatic risks. So I have two questions:

1) How are those data affected by those NOAA cuts?

2) Even if the data is not affected, I'm considering substituting those sources. What are some candidates? For NasaPower, #era5 looks like a good candidate. What about precipitation? Any jaxa products?

Der Mai 2025 war global der zweitwärmste Mai seit Beginn der Aufzeichnungen.

Laut ERA5-Daten lag die durchschnittliche #Oberflächentemperatur 0,53 °C über dem Mittel von 1991–2020 und 1,40 °C über dem vorindustriellen Niveau.

Nur der Mai 2024 war wärmer. In den letzten 23 Monaten überschritt die globale Temperatur 14-mal deutlich die 1,5-Grad-Marke.

Since July 2023, 21 of the last 22 months have seen global average temperatures 1.5ºC above the pre-industrial level, according to #ERA5 data - with July 2024 just 0.02°C below that mark.

Anyone out there got any tips on converting ERA5 .grib files? Trying to get a load of data for a project at work and running up against the CDSAPI computation limits for netcdf files (unless I want to split files daily massively increasing the number of total requests). Running up against error after error with xarray, earthkit and cfgrib when trying to convert. Would love some help.

Out now! Available in the #C3S data store: ERA5 hourly time-series data on single levels from 1940 to present. As a regridded subset of the full #ERA5 dataset on native resolution, it is designed for retrieving long time-series for a single point.

The C3S global temperature trend monitor, based on #ERA5, allows you to explore how the estimate of the time to 1.5°C global warming has changed in recent years. While it should not be interpreted as a forecast, it does show trends in global warming.

Time series - near-surface air temperature

This chart shows daily averages of global mean near-surface air temperature anomalies from the #ERA5 global reanalysis dataset, from January1940 up to two days behind real-time.

Reanalysis datasets like #ERA5 combine conventional weather observations and data from satellites with a computer model of the Earth system. But what does that mean in detail and what is the degree of uncertainty of ERA5 temperature data?

Predicting climate trends, guiding policies, and protecting communities: #ERA5 is a foundation for informed decision-making and action.

📣 We are pleased to announce that the much awaited #ERA5 and ERA5-Land post-processed daily statistics have been released as datasets in the new Climate Data Store, replacing the legacy ERA5 daily statistics application.

Did Copernicus Climate Data Store completely borked #ERA5? I'm downloading monthly data and the date information is bonkers. The coordinate is now called "date" (instead of time) and it's not a real time with units, it's just ISO dates as integers. It's impossible to correctly process with CDO and ncivew is throwing a fit.

Oh guck. #Era5 von Copernicus ist auch nicht von Helene betroffen und hat die letzten 2 Monate auch kein Plateau und auch zuletzt keine Steigerung https://pulse.climate.copernicus.eu
Ist interaktiv. Muss man die Kachel Sea Surface Temperature anklicken, sonst sieht man eingangs die air temperature.

#CopernicusClimate is digitising historical climate data from Africa, enhancing reanalysis datasets like #ERA5 via a new data rescue portal developed with WMO.
👆 A valuable resource for researchers and policymakers.
