Quick post. I’ve been travelling and laptop battery has failed, so no posts for last two weeks.
September was the ‘hottest month evah’ in the UAH satellite data series since 1978, by quite some margin.
As Ron Clutz says here:
Remarkably, in 2023, SH land air anomaly shot up 1.5C, from -0.56C in January to +0.93 in July, then dropped to 0.53 in August. Now in September SH shot up again to 1.5C. Tropical land temps are up 1.48 since January and NH Land air temps rose 0.9, mostly since May. The consolidated rise greatly exceeds the upward spikes peaking in 2016.
As I said in this post:
Another thing to note is that warming is expected to be more intense in the southern hemisphere. At the moment, according to Dr Roy Spencer, there is more warming occurring in the northern hemisphere and the tropics. However, Roy Spencer does note that the southern hemisphere land anomaly is a record and we know that land warms a lot more quickly than ocean (of which there is a lot in the southern hemisphere!). Look at Australasia - a huge anomaly of 1.43, increased from 0.06 in June. This would appear to confirm that the southern hemisphere is starting to respond to the water vapour perturbation from Hunga Tonga. When the oceans respond, it may get very warm indeed.
So in future months we should see an accelerated warming in the southern hemisphere if Tonga is indeed responsible for this spike in global temperature.
It’s highly unlikely that the current remarkable warming is due to El Nino, even more unlikely that it is the result of man-made greenhouse gases. La Tonga - which has injected unprecedented amounts of water vapour into the stratosphere, is the most likely cuplrit. Watch this space.
Tom Nelson and Matthew Weilicki discuss the impacts of Hunga Tonga on temperature in a recent podcast. It's very insightful and convincing. It is utterly implausible (for me) to believe that a trace gas that seems to be steadily increasing (the vast majority of which is naturally produced) could have such profound effects on temperature over such a short duration. It's preposterous and illogical.
There is a NOVA episode about the eruption. Season 50 Episode 8, aired May10. You should be able to find it online. Most recent NOVA seasons are pretty Woke and they really promote Global warming. This is still a good episode to watch.
