Climate “Scientists” Say Human Cause Doom-Warming Started Earlier Than Thought

This confuses me, because, generally, the Cult of Climastrology claims human-induced warming started in the 1850s, but, hey, they always need Narratives

Scientists looked back in time to find the first signs of human-caused global warming. It’s far earlier than previously thought

The human fingerprint on global warming was likely evident in Earth’s atmosphere far earlier than previously thought—even before the invention of modern cars, a new study says.

Using a combination of scientific theory, modern observations and multiple, sophisticated computer models, researchers found a clear signal of human-caused climate change was likely discernible with high confidence as early as 1885, just before the advent of gas-powered cars but after the dawn of the industrial revolution.

The minute you mention computer models, you know it is mule fritters

The findings, detailed in a paper published Monday in the journal Proceedings of the National Academy of Sciences, raise the likelihood that humanity has been remaking the planet’s climate in a detectable way for longer than previously believed—and highlight the importance of tracking changes in the upper atmosphere.

Scientists had begun to record surface temperature observations by the mid-19th century. The start date for a detectable human signal in surface temperatures has generally been thought to be in the early-to-mid-20th century, though other parts of the climate system showed signs of change at different times.

Really? I’ve almost never seen the cult say it started in the early to mid 20th Century. Are they just attempting to re-write this for some nefarious purpose?

The signal of climate change was detectable in the 19th-century atmosphere after just a 10 parts per million increase in carbon dioxide concentrations in the 40 years between 1860 and 1899. For comparison, planet-warming carbon dioxide levels skyrocketed by about 50 parts per million between 2000 and 2025, Santer said.

Do they have actual measurements of this? The paper doesn’t make that clear. And, how do they know, how do they prove, that it was caused by Mankind, instead of just changes from a Holocene cool period to a warm period?

Andrea Steiner, a climate scientist at the Wegener Center for Climate and Global Change at the University of Graz in Austria, told CNN the study shows human-caused climate change can be detected earlier in the atmosphere than at the surface.

And they were able to gather the actual CO2 readings from the atmosphere from the earlier time frame how? Sounds like BS to me.
