    After nearly two weeks of overwhelming uncertainty, today it happened. I was fired from my dream of working at NOAA. I'm so sorry to everyone also affected. My job was to strengthen NOAA's use of machine learning and AI for subseasonal-to-decadal weather and climate prediction

    Uh. Graphic from zacklabe.com/antarctic-sea-….
    Line graph time series of 2023's daily Antarctic sea ice extent anomalies in red shading compared to each year from 1979 to 2022 using shades of purple to white for each line. Anomalies are computed relative to a 1981-2010 baseline. 2023 is a negative outlier for this time of year. There is substantial interannual and daily variability. There are no clear long-term trends.

    As always, my last tweet of the year - rising carbon dioxide (CO₂)... There is no deadline. Any reduction in emissions will reduce future climate warming. I am hopeful! Thank you all for following! 🙂 + Visualization/info by @gcarbonproject: globalcarbonproject.org/carbonbudget/2…

    Wow, another new record! Last month was the warmest September on record globally 📈 [Summary of data: climate.copernicus.eu/surface-air-te…]

    The extreme event continues to unfold in the high #Arctic today in response to a surge of moisture and "warmth" 2018 is well exceeding previous years (thin lines) for the month of February. 2018 is the red line. Average temperature is in white (sites.uci.edu/zlabe/arctic-t…)

    I keep thinking we've reached the largest anomaly (in terms of absolute magnitude), but that's not the case yet. The #Antarctic departure continues to widen. Apologies if you are tired of seeing me post this same graphic. Other graphical perspectives at zacklabe.com/antarctic-sea-…

    Wow, January 2020 was the warmest on record and greater than 3°C above the 1981-2010 climate average in Europe. The average global temperature was also the highest on record. 🔥 More info (@CopernicusECMWF): climate.copernicus.eu/surface-air-te…

    End of 2019 reminder - 5 warmest years on record are in the last 5 years. Plot shows global climate variability (bumps) and climate change (long-term upward trend). The 12-month running mean is >1.2°C above pre-industrial levels. [Description of graph: columbia.edu/~jeh1/mailings…]

    This is quite astounding... Today's #Arctic sea ice extent is almost 500,000 km² *lower* than the previous record low for the date [using JAXA data]

    This is Arctic climate change ⬇️ "...the thickest ice—usually more than four years old—had declined by more than 86% since 1985 to make up just 2% of total ice in 2020" climate.gov/news-features/…
