Note: Please be aware that I mostly post on my Briefed by Data substack. If you like sustainaiblitymath then you may very well like Briefed by Data. For example, this graph and one with all months can be found in this post. Please check it out.

As you can see, May 2024 was a record for May, but when we look at all months, the El Niño effect is clearly fading. In the all-month graph, the May 2024 anomaly is in line with recent neutral conditions. Here is what NOAA had to say about May 2024. It is almost as if you can predict ENSO by the monthly anomaly

May had a record-high monthly global ocean surface temperature for the 14th consecutive month. El Niño conditions that emerged in June 2023 were replaced by ENSO-neutral conditions during the past month, and according to NOAA’s Climate Prediction Center La Niña is favored to develop during July-September (65% chance) and persist into the Northern Hemisphere winter 2024-25 (85% chance during November-January).

Time series data can be found at the top of the NOAA page.

With El Niño still hanging around April set a record, but it is in the pattern we would expect. A record, but not surprising.

Here is what NOAA has to say for April 2024 (data can be found there):

Global land-only April temperature was warmest on record at 1.97°C (3.55°F) above average. The ocean-only temperature also ranked warmest on record for April at 1.03°C (1.85°F) above average, 0.17°C (0.31°F) warmer than the second warmest April of 2023, and the 13th-consecutive monthly ocean record high. These temperatures occurred as the current El Niño episode nears its end. El Niño conditions that emerged in June 2023 weakened further in April, and according to NOAA’s Climate Prediction Center, a transition from El Niño to ENSO–neutral is likely in the next month, with odds of La Niña developing by June–August (49% chance) or July–September 2024 (69% chance).

You can find the all-month graph and other news over at the Briefed by Data post QTRS.

According to NOAA

March 2024 was the warmest March on record for the globe in NOAA’s 175-year record. The March global surface temperature was 1.35°C (2.43°F) above the 20th-century average of 12.7°C (54.9°F). This is 0.01°C ( °F) warmer than the previous March record set in 2016, and the tenth consecutive month of record-high global temperatures. March 2024 marked the 48th consecutive March with global temperatures, at least nominally, above the 20th-century average.

You’ll find the same type of graph, but for all months, on my Briefed by Data site post Quick Takes. You’ll find the data at the NOAA link above.

The October temperature anomaly was a top-5 anomaly overall and a record for October, but this shouldn’t be surprising. If one follows the red bars and El Niño months, the 2023 anomaly follows that trend, and the expectation is that October 2023 will officially be an El Niño month. Expect more record monthly anomalies because (from NOAA)

El Niño conditions that emerged in June continued into October, and according to NOAA’s Climate Prediction Center there is an 80% chance that El Niño will continue through the Northern Hemisphere spring (March–May 2024).

NOAA has the time series data. More on this and other notes can be found in my Briefed by Data Quick Takes post.

September 2023 set a record for a monthly anomaly, but when you read something that says it was surprising, outrageous, crazy, etc., you are being misled. As far as I’m concerned, this is the media making matters worse. A new record anomaly like September is expected, and, in fact, it will happen again. Suggesting that scientists didn’t know this implies that they aren’t credible. Please read the full argument here and while you are there, subscribe to my Substack Briefed by Data.

Summary from NOAA, which has the data available:

The September global surface temperature was 1.44°C (2.59°F) above the 20th-century average of 15.0°C (59.0°F), making it the warmest September on record. September 2023 marked the 49th-consecutive September and the 535th-consecutive month with temperatures at least nominally above the 20th-century average. September 2023 was 0.46°C (0.83°F) above the previous record from September 2020, and marks the largest positive monthly global temperature anomaly of any month on record. The September 2023 global temperature anomaly surpassed the previous record-high monthly anomaly from March 2016 by 0.09°C (0.16°F). The past ten Septembers (2014–2023) have been the warmest Septembers on record.

Here is an excerpt from my Briefed by Data post Minerals for renewables:

A few things stand out. The first is the amount of minerals utilized for offshore wind, which is 50% more than for the next category, onshore wind. The second factor is the importance of copper in all energy sources. Figure 2 shows the copper price from FRED. Prior to 2004, the price remained below 3,000 per metric ton, and it has climbed around four to five times since then.

In my post of the same name on Briefed by Data I make the case that normalizing energy subsidies by BTU in the same year is misleading. If you do so you get the graph here and can make statements like solar gets 300x more subsidies than nuclear per BTU.

In fact, solar subsidies per BTU are higher than for every other energy source, including wind (solar is 4.4 times higher) and oil and gas (solar is 135 times higher). This metric has three flaws, in my opinion.

Read the three reasons I give. The post includes links to the EIA data.

From my post of the same name on Briefed by Data. Figure 1 shows that the August 2023 anomaly was a record for August by a half degree Fahrenheit, or about a 30% increase over the previous record in 2016. Here is what NOAA has to say about August 2023:

The August global surface temperature was 1.25°C (2.25°F) above the 20th-century average of 15.6°C (60.1°F), making it the warmest August on record. This marked the first time an August temperature exceeded 1.0°C (1.8°F) above the long-term average. August 2023 was 0.29°C (0.52°F) warmer than the previous August record from 2016, but the anomaly was 0.10°C (0.18°F) lower than the all-time highest monthly temperature anomaly on record (March 2016). However, the August 2023 temperature anomaly was the third-highest anomaly of any month on record.

Links to the data are in the post, plus two other graphs.

I did a full summary of July on Briefed by Data and here is a  highlights from the post.

First, Figure 1 represents the July historical temperature anomaly. It was certainly a record-setting year for July, on the order of 0.75 °F above the previous record anomaly. It should be noted that ENSO status will not be formally determined for some months. How does this compare to all months?

July’s anomaly was not even a top 10 for a month (see Figure 2 in the post) but it was a warmest month on record, but this is an artifact of July being the warmest month of the year in general. Read more here which includes links to the data.

Grip strength is one of the factors measured in the National Health and Nutrition Examination Survey (NHANES). Grip strength, which is formally tested by gripping a dynamometer, is also a proxy measurement for upper body and total strength. The median summed (right plus left hand) female grip strength is 64% of the median summed male grip strength. Measures of central tendency do not tell the whole story, and we can see from the distribution that relatively few females exceed the male median. In fact, just 17 of the 2,515 females, or less than 0.1%, have a summed grip strength greater than the median summed grip strength of males. Read more about this on my substack Briefed by Data,
Female vs Male Grip Strength, where I include links to the data and two other graphs.
