Like a broken record, another monthly record for the average sea surface temperature in the northern half of the Atlantic Ocean...

Data available from NOAA ERSSTv5 (https://psl.noaa.gov/data/gridded/data.noaa.ersst.v5.html).

@ZLabe I prefer this type of graph, it factors in that the data is cyclic and shows much better where the trend is going

@ZLabe warning ⚠️ signs everywhere and wait for when the CH4 & CO2 heat captures form a cooperative feed back loop 🍿 😳😬

Some cooler sea surface temperature (SST) departures continue to linger in the Sea of Okhotsk and Bering Sea. However, a sharp gradient in SST anomalies is found around Scandinavia with the warmest areas to the south and in the Baltic Sea.

Data from https://psl.noaa.gov/data/gridded/data.noaa.oisst.v2.highres.html

Polar stereographic map showing sea surface temperature anomalies in May 2024 relative to 1982 to 2010. Most areas are warmer than average. Sea-ice cover is also shown if sea-ice concentration is at least 15% per each grid point. Red is shown for warmer sea surface temperatures, and blue is shown for colder sea surface temperatures. Data is from OISSTv2.1.

    100 years of average January-May temperature anomalies over land areas through 2024... not great!!

    [Data from GISTEMPv4; some missing data prior to ~1960, especially over the Antarctic and Southern Ocean]

    Animation of global maps showing January to May surface air temperature anomalies over land for each year from 1925 to 2024. There is a long-term warming trend. Anomalies are calculated relative to a 1951-1980 baseline using NASA/GISS GISTEMPv4.

    Wonderful illustration.

    Thanks.

    Hopefully this illustration becomes widely seen.

    Temperature anomalies over the last month (left), 3 months (center), and 12 months (right) in the Northern Hemisphere...

    Data from @CopernicusECMWF ERA5 reanalysis at https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-single-levels-monthly-means?tab=overview

    Three orthographic maps showing 2-m air temperature anomalies in May 2024, March 2024 to May 2024, and June 2023 to May 2024. Red shading is shown for warmer anomalies, and blue shading is shown for colder anomalies. Most areas are warmer than average. The mean temperature anomaly for each map is also displayed. Anomalies are calculated relative to a 1981-2010 baseline.

    @ZLabe @CopernicusECMWF thank you Zack for all of your posts, I think visuals are effective for showing the drastic changes across the globe.

    Happy Friday! Enjoy your weekend! Here's your latest ice update - sea ice extent is currently the 6th lowest on record (JAXA data)...

    • about 100,000 km² below the 2010s mean
    • about 780,000 km² below the 2000s mean
    • about 1,290,000 km² below the 1990s mean
    • about 1,730,000 km² below the 1980s mean

    More plots: https://zacklabe.com/arctic-sea-ice-figures/

    Line graph time series of 2024's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with white for the 1980s, green for the 1990s, blue for the 2000s, and purple for the 2010s. Thin white lines are also shown for each year from 2002 to 2022. 2024 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between April and July by looking at the decadal average line positions.

    The temperatures averaged across nearly all latitude bands were warmer than the 1951-1980 average in May 2024.

    [Plot shows zonal-mean surface temperature anomalies, with latitude = y-axis (not scaled by distance). GISTEMPv4 data.]

    Temperatures in May 2024...
    🟥 - warmer than average
    🟦 - colder than average

    The average global air temperature was...
    +1.14°C above 1951-1980 baseline
    +1.27°C above 1921-1950 baseline
    +1.42°C above 1880-1920 baseline

    ALARMS.

    They warned for DECADES, Exxon lied, LIES, called it a hoax.

    Now the warnings ARE TRUE, but the effects ARE WORSE.

    Canada burned 30 billion trees last year.

    Scale is hard to under stand, 30 billion trees is three hundred times the size of all combined annual logging in Canada, three centuries of logging. Canada isnt 200 years old.
    WORSE than the warnings.

    FIRST end burning carbon, BUILD the replacement AT SPEED.

    REPLACE ALL carbon burning engines, today.

    Looking for the status of greenhouse gas levels, here is the latest monthly data...

    Monthly observations provided by: https://gml.noaa.gov/ccgg/. Compare this to the last 800,000 years: https://epa.gov/climate-indicators/climate-change-indicators-atmospheric-concentrations-greenhouse-gases.

    Graphic shows three line graph time series of monthly carbon dioxide abundance in ppm (blue line), monthly methane abundance in ppb (red line), and monthly nitrous oxide in ppb (purple line). Graphs are all shown from January 1984 through February 2024/May 2024. Current levels of CO2 are 427 ppm. Current levels of methane are 1929 ppb. Current levels of nitrous oxide are 338 ppb. All graphs show long-term increasing trends along with some interannual variability and seasonality.

    One man's record emissions is the next man's peak emissions, either way you always have an excuse to crack the champagne over your fellow man's head.

    Last month was also the warmest May on record globally in the GISTEMPv4 dataset...

    [(Preliminary) data/info: https://data.giss.nasa.gov/gistemp/faq/]

    Line graph time series of global mean surface temperature anomalies for every May from 1880 through 2024. A red 30-year lowess smoothing line is also shown. Anomalies are computed relative to a 1951-1980 baseline. The global mean surface temperature anomaly in May 2024 was +1.14°C. There is large interannual variability and a recent long-term warming trend.

    Methane (CH₄) is a potent greenhouse gas. Here are the most recent monthly observations...

    February 2024 - 1928.96 ppb
    February 2023 - 1920.26 ppb

    Red colored line graph time series of global atmospheric methane abundance from January 1984 through February 2024. Methane abundance is measured in units of parts per billion. Current levels are 1929 ppb. A seasonal cycle is visible on the graph. There is also decadal variability and a long-term increasing trend.

    sea ice extent has recently dropped to the 2nd lowest on record for the date in response to a slowdown in the rate of the sea ice freeze-up (austral winter).

    More graphs: https://zacklabe.com/antarctic-sea-ice-extentconcentration/

    Line graph time series of 2024s 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 the record low for most days, which is shown in yellow. There is substantial interannual and daily variability. There are no clear long-term trends.
