When policymakers are told:
Rapid warming is unprecedented. Climate instability is uniquely modern. Current rates are outside natural bounds.
They are not being given the full paleoclimate context. This paper has it. A newly published paper in Climate of the Past provides something climate science could use more of: large-scale, data-driven reconstructions grounded in proxy evidence rather than projections. The study, “A global analysis of pollen-based reconstructions of land climate changes d...

The EU would rather eat bugs than be real about its energy problems — RT World News:
The EU would rather eat bugs than be real about its energy problemsIt’s dawning on some in Brussels that by cutting out Russia, they’ve simply switched dependencies – except they couldn’t even do that right

Will it take them long to start looking like chicken?
I live in flyover country, far from the temperature regulating effects of any oceans.
On some summer days, it is 64F at 6AM, and 104F by 4PM. That is a temperature increase of 4 degrees per hour.
Compare that to the “dangerous rapid warming” due to climate change.
For the sake of argument, let’s estimate the world has warmed 2F over the last century.
The daily variance of 4F/hour is 1.8 million times more rapid than the global warming rate. (4 degrees/hour x 24 hours/day x 365 days/year x 100 years/century divided by 2F/century)
All of the plants and animals in my locale seem to have no problems whatsoever with that rate of temperature change that happens multiple times per year.
Hear me out. Everything you say is true, but it’s highly unlikely that you will survive whatever happens over the next century. /s
Lol.
Then, is there a GCM [general currency model] that tells me when I should max-out
my credit cards (so I can party a lot, but won’t be around to pay them off?) ?
Knew someone who did that. Turns out the terminal cancer diagnosis was wrong.
Given the estimated maximum life for homo sapiens, I can clearly affirm I will not live 100 more years. 🙂
Here at 2500m in Teller Co CO the diurnal max-min is ~ 20c , 36f , year round .
And all CO2 based life is supposed to be in peril over an ` unprecedented 2c per century ?
One of the first red flags that diverted me into this brouhaha in 1980s was the claim that CO2 was causing warming which would take decades to show up .
The atmosphere has damn near 0 memory .
GISP data shows several period of warming, and cooling, of at least similar steepness , and far more protracted, than the tiny little blip since 1900
Source ? Provenance ? Attribution ?
The GISP data is from RB Alley (2000)
Not sure where this version is from, but there are lots if you search “GISP Ice Cores”… and view images
This is one with the least added ‘stuff’
A recent article provides data for an estimate of how global mean sea level varied over the history of the Pleistocene: Global mean sea level over the past 4.5 million years | Science
Basically, both rising seas and declining seas, presumably resulting from temperature changes, are not much different than what we are observing today, without the benefit of modulation from anthropogenic sources. The slopes are similar for rising and falling episodes, and seem to establish a band over which the max and min are restrained. This argues that anthropogenic contributions are irrelevant and the system is driven by internal processes. Thus, increasing CO2 is more likely to be the result of biogenic processes rather than the cause of increasing temperatures.
Ice core analysis shows some 25 rapid warming events in the past where temperatures rose by 5 to 15 degrees in as little as 50 years. They are called Dansgaard events after the Danish scientist who discovered them. Here’s a bit from encyclopedia Britannica on them:
https://www.britannica.com/science/Dansgaard-Oeschger-event
Warming after the Younger Dryas took place over approximately fifty years. Although it is the longest produced vehicle model, I don’t believe there were any Suburbans during that era.
No indeed, there was the Atlantic ocean to Greenland’s south however, which would have been/is subject to currents from the sub-tropics. (N Atlantic drift returning south via the AMOC).
Seems evident that there was major shift in those currents causing an atmospheric coupling.
It is plainly a local (as in not global) phenomenon, as there is no way that the whole globe could warm by that amount in such a short time, and certainly not without there being multiple other global evidence.
Plus, there were more iterations of the DG events indicating an ocillation between ocean and atmospheric coupling.
Ah. A fan of “The Day After Tomorrow.”
So, in summation, it is all just weather. Good to know.
And weather is variable from year to year, sometimes drastically. And sometimes there are a string of hot years, and sometimes a string of cold years, and wet and dry, too. We can read historical accounts that show this has happened throughout human history. And it’s ALL just weather, and the sky is NOT falling…
I live in western Pennsylvania, the weather is drastically variable from day to day. Hell, from hour to hour. 6 months out of the year we can experience all four seasons in a day. 😉
