Warming Could Push Atlantic Past ‘Tipping Point’ This Centur

[bluemingidiot]

"The system of ocean currents that regulates the climate for a swath of the planet could collapse sooner than expected."

"The last time there was a major slowdown ... it seems to have plunged Europe into a deep cold for over a millennium."

Questions:

1. Has the earth ever been warmer than now in recorded history? If so, what caused it?

2. Was there a major slowdown in ocean currents? If so, did they seem to plunge Europe into a deep cold for over a millennium?

3. If we don't know if there was a major slowdown then, how do we know there will be a major slowdown this time?

4. Are there any other reasons for Europe to have gone into a deep cold 12,000 years ago?

5. What caused Europe to warm up after the 1,000 years?

6.  If Europe goes into a deep cold, what is the rest of the world going to do?

Humans can usually adapt. Working together would be the key but that most likely won't happen!

All good questions, bluemingidiot, but I'm not sure anyone actually has the answer. All we can do is work with what we get. While I don't necessarily doubt that the climate is changing, I'm not convinced that humans are having a major impact. Things are always changing, and we may just be thinking too highly of ourselves by thinking we have that much influence.

The questions are mostly rhetorical. Worldwide ocean temperatures have only been kept since 1980. That's 43 years. You have a much better chance of predicting the 2024 presidential election by polling 43 people than you have of predicting future weather activity based on this small sample.

"contrary to previously thought, there is no globally synchronous warm period during the Holocene. Instead, the warmest temperatures are found at different times not only in different regions but also between the ocean and on land. This questions how meaningful comparisons of the global mean temperature between reconstructions and models actually are."

The last 12,000 years show a more complex climate history than previously thought (phys.org)

Holocene Epoch (11,700 years ago – present day)
The Holocene is a brief flash of time compared to previous epochs and is, in reality, just an interglacial period of the current ice age. All of recorded human history has occurred entirely within the Holocene.
