Part of this may have been due to the Hunga Tonga eruption which injected an tremendous amount of water vapor into the upper atmosphere

From the NASA article: "The effect would dissipate when the extra water vapor cycles out of the stratosphere and would not be enough to noticeably exacerbate climate change effects."

I feel like there must be some other influence here, and the Tonga eruption is a good candidate. That's not to say this isn't already exacerbated by existing human-derived climate change, but the way the temperature leaps off the chart starting in April is not like the gradual upward trend we see with climate change. It makes utterly no sense from that perspective. Something external to climate change has to be influencing the system.

Unfortunately, it also seems like a lot of people are hesitant to even discuss this possibility for fear of being ostracized by the mob.

“ Unfortunately, it also seems like a lot of people are hesitant to even discuss this possibility for fear of being ostracized by the mob.”

This assessment is the same that a climate denier would make - it’s essentially climate gas lighting. Why do I say this?

Because the real reason it’s hard to discuss events with nuance is the highly vocal contingent of climate deniers that are looking for any single word or event that can be twisted to obfuscate the issue - first deny climate change, then to claim it’s not that bad etc etc.

That is the actual reason people are careful discussing climate, nothing to do with fear of ostracism. they’re rightly worried that the vocal anti-science people will twist their words.

The only people who fear getting ostracized are those doing the word twisting, the others are simply hesitant to give the Ron desantis types sounds bites to twist.

Apparently warming is compounded by the eruption, low sulphur shipping fuel rules, low amounts of Saharan dust and changes by El Niño according to this:

There's something called a tipping point, and it can result in exactly that sort of sudden rate of change increase entirely due to a certain threshold being breached.

What is the mechanism for They ostracizing anonymous accounts on HN?

[convolvatron]

maybe a lot of people are tired of hearing people flog uniformed opinions and third-hand speculation. its not really a very productive discussion.

[raverbashing]

Humm that's curious

Also, the temperature anomalies seem to be close to the El Nino temperature changes (which is a big blob of hot water over the Pacific)

[refulgentis]

And its the first el nino year in a few years!

A much more compelling argument than your sibling arguing a mob is suppressing anonymous discussion lol.

[marstall]

also it's an El Niño year.
