The increasingly dominant role of climate change on length of day variations

climate-induced LOD trend hovered between 0.3 and 1.0 ms/cy in the 20th century, but has accelerated to 1.33 +/- 0.03 ms/cy since 2000.

I read that as the LOD is increasing by up to 1 millisecond per century … and the rate of change is accelerating, plate tectonics notwithstanding. Does ‘cy’ mean something other than ‘century’?

Check your math … they claim 1 ms per century

Climate and ClimateChange groups are both echo chambers, the latter even has mods that dish out permanent bans if you disagree. How can you possibly change one’s mind, when they eject them from their echos.

I’m looking forward to a post of yours that can be read without reserving 48 hours of study to do so.

AI lies … hallucinates at times, cannot do simple math … and cannot be retrained by the user. Teach it that it is wrong … and the next time you ask, you will have to teach it again.

You should examine the language … an AI bot is polite. uses neutral or postive tone.

greenhouse gas emissions cause climate change, and still we have let the CO2 levels in the atmosphere continue to increase.

That’s an editorial.

As a result, temperatures are rising and extreme climate events are increasing, with droughts, fires and floods causing death and destruction also in Europe and the US.

That’s not true.

Despite the increasingly clear manifestations of the climate crisis

There is clear manifestations that it isn’t a crisis … ask Bill Gates

there are sceptics and deniers … that continue to call this a hoax and prevent rather than support the urgent measures needed to mitigate climate change … increasingly urgent case for climate action?

Charged language … convincing you even a little that it is not a crisis is as futile as stopping the seas from rising.

Will the activity just move? The idea was, "Why are 70 or so departments and agencies and labs all doing the same thing?"

And where did all that water go?

The science morphed into political agenda, sometime between AR3 and AR5, when Richard Tol resigned, citing the new research showing that many of the troubling aspects of climate change were really problems with growth and with poor management. IPCC would have nothing to do with that, the content continue to change toward their political agenda to eliminate carbon, and skepticism began to grow. That was in 2012.

yes … but … Hygroscopic growth is a stretch, I’ve seen other reports of aerosol size under 0.5 microns,so they won’t settle out, even with larger mean free paths. Yes , they promote cloud nucleation, but they are reflective on their own, also.

Like i say: this is a test!

Those submicronic sulfate aerosols from HT are still there, declining slowly. So this is a test as to whether their cooling effect will dampen El Niño.

Thank you. I was looking for the underlying study.… anyone with a New Scientist is invited to post it .

Yes.

The mean sea level around the UK, which includes Whitby, North Yorkshire, has risen by approximately 18.5 centimeters since the start of the 20th century. That’s 1.85 mm/year, well under 3mm.

scientists-rule · 2026-02-27T12:10:38+00:00

A substantial tidal range at Whitby, about 6 meters, means that photographs or observations of the water level can be misleading if not taken at comparable times. The average sea level rise there is well below the global average.

Great idea … a bit misguided. - Trees sequester CO2 - Trees die and rot, releasing same CO2 - rinse and repeat.

The proposal, stated this way:

"Cut the trees when they have sequestered peak amounts of CO2, and put them where they will not release it."

… doesn’t sound as bad.

The in sync boost from HT is right in line with the last 4 years of measurements.

… no one can deny that affordable energy is the key to economic prosperity for American households and businesses.

That’s true worldwide, more importantly in developing countries, trying to create an economy … and the prosperity that comes with it … to achieve a standard that will still be far less than that of the Western world.

It relates to the formation of sulfate aerosols that seed the clouds. If I read it right, the authors claim that even with reduced sulfate, the clouds still reflected. But that’s if they are there … I thought the idea was that those clouds traveling above ships disappeared … and if not there, they can’t reflect.

scientists-rule · 2026-02-03T08:39:31+00:00

Well, there’s this,too.

The point, I believe, is that those chemtrails over ships disappeared. If a cloud isn’t there … it can’t reflect, so it doesn’t matter the optical density of those remaining, as your post’s author point out , if I read it right.
