Interesting to compare with previous years and important to note that (I believe) the dataset used only goes back to 1981 (satellite era).
This graph https://climatereanalyzer.org/clim/sst_daily/ shows the daily sea surface temperatures, but not they are only calculated for 60N-60S (the dataset is explained below the graph).
I'm always extremely cautious with phrases like 'record breaking' as one does need to look carefully at the data used and compare like with like. Having said that, the warming theme is there to be seen by all. We didn't;t have access to such data in the past and so it's a privilege to see it now.
It does seem there is a strong link between CO2 and temperature and that humans are very likely to be the cause of additional warming over and above natural warming. The rapid access to the data does mean we have the ability to do something about our contribution to warming if we choose to do so.
As for the 'what if you're wrong?' argument, then that's a 'down the pub' discussion, but probably better to do something than not I believe.
There is a lot of hysteria still regarding anthropogenic climate change but I think in recent years we have seen much 'good data' becoming available and that does lead one to suggest action is probably needed.
A final note, I'm also cautious about attribution of individual events to climate change. It's interesting to see the rapid attribution now taking place, and the statistical methods behind it; but I do remain sceptical.
Above all, the atmosphere, weather and climate are king (or queen) of us all!
Oh, you might like this animation. It shows temperature anomaly in the equatorial Pacific Ocean. latitude is along the bottom scale, water depth the left hand scale. Notice the cold water at the top of the chart in March, and the warm water around 150 meters. Then see how the warm water comes to the surface; this is the La Niña changing to the El Niño!
