Oh look, it's me, interrupting your evening with another outrageous climate graph.

Terrible news from a study out today on emperor penguins in the Antarctic (https://www.nature.com/articles/s43247-023-00927-x):

"Of the five breeding sites in the region all but one experienced total breeding failure after sea ice break-up before the start of the fledging period of the 2022 breeding season. This is the first recorded incident of a widespread breeding failure of emperor penguins that is clearly linked with large-scale contractions in sea ice extent."

"Overall, there is almost no ice over four years old remaining—it now comprises just 3 percent of the total ice cover. This is the same percentage as last year and contrasts starkly with the late 1980s when 30 to 35 percent of the Arctic Ocean’s ice was older than 4 years."

#Antarctic sea ice remains on its own this year compared to any other July in our satellite record. Keep in mind when looking at this graph that the y-axis interval is 1,000,000 km². This is a massive deviation from the previous record for the date.

Oh my - just started to update my own visualizations for July's global (sea surface) temperature data, and let's just say that I am revisiting the formatting of the y-axis maximum limits 🥴

I've designed a new graphic showing the daily ranking for sea-ice extent in nearly every #Arctic region. This graphic will be updated several times per week at: https://zacklabe.com/arctic-sea-ice-extentconcentration/. Let me know if there are issues.

If this graphic is useful, I will add an #Antarctic version. #DataViz #SciComm #OpenScience #OpenData

It was an unbelievable year for global climate.

As data is released in the first two weeks of January, you are going to be hearing all about these new climate change records. Apologies for all my graphs in advance!! 😬

The rate of #Antarctic sea ice growth has slowed down even more in the last few days...

100 years of June temperature anomalies over land through 2023. It will get even hotter.

Data from https://data.giss.nasa.gov/gistemp/.

Animation of global maps showing land surface temperature anomalies for each June over the last 100 years through 2023. There is a long-term warming trend in all areas and large spatial variability. Anomalies are computed relative to a 1951-1980 baseline. Blue shading is shown for colder anomalies, and red shading is shown for warmer anomalies.

Global sea ice extent remains at a historic low for this time of year due to unusually small ice cover at both poles (but especially the Antarctic)...

ZLabe, 9 months ago to random

The extent of global sea ice cover remains record small for this time of year. Both poles are unusually low, but the largest departure is currently coming from the extreme event in the Antarctic.

Uh, yeah, this is still happening...

Yeahhh, the last three months have observed a lot of warmth globally - visible across all latitude bands...

Latest 'cloud-free' mosaic from MODIS satellite imagery showing the lack of #Arctic sea ice and thus greater areal coverage of open water (compared to past decades). Note also the large phytoplankton bloom and drifting wildfire smoke.

Happy #DecemberSolstice! 🌞

Understanding seasons - a look at the hourly incoming solar radiation during the two solstices (23.5°N/S). I've added a red marker for ease of viewing. Dashed line shows the equator
