Give me all relevant info on the catastrophic cyclical events on earth (spanning aprox 12-27k years)
ChatGPT Cyclical events that span approximately 12,000 to 27,000 years on Earth are often associated with astronomical phenomena and geological processes. Here are some relevant topics related to these cyclical events:
Milankovitch Cycles: Milankovitch cycles refer to variations in the Earth's orbit, axial tilt, and precession over long periods. These cycles are believed to play a role in shaping the planet's climate and have a periodicity of around 23,000 to 100,000 years. Changes in these orbital parameters can influence the amount and distribution of solar radiation reaching Earth's surface, potentially leading to climate variations.
Ice Ages: Ice ages, also known as glaciations, are periods of extensive glacial advance followed by retreat. These occur over long timescales and are linked to Milankovitch cycles. The last major ice age occurred approximately 20,000 years ago and lasted until about 10,000 years ago. Ice ages can have profound effects on sea levels, ecosystems, and global climate patterns.
Mass Extinctions: Throughout Earth's history, there have been several mass extinction events where a significant portion of species on the planet went extinct. While not necessarily cyclical, these events have occurred sporadically over millions of years. Notable mass extinctions include the Permian-Triassic extinction (approximately 252 million years ago) and the Cretaceous-Paleogene extinction (around 66 million years ago), which wiped out the dinosaurs.
Geomagnetic Reversals: Earth's magnetic field periodically undergoes reversals, meaning the magnetic north and south poles switch places. These geomagnetic reversals are recorded in the rock record, and they occur irregularly over long timescales. The most recent reversal, known as the Brunhes-Matuyama reversal, happened approximately 780,000 years ago.
Supercontinent Cycle: The movement of tectonic plates on Earth's surface leads to the assembly and breakup of supercontinents over millions of years. The most famous supercontinent is Pangaea, which formed about 300 million years ago and later broke apart. This process is believed to occur in cycles, with supercontinents forming and dispersing roughly every 300 to 500 million years.
It's important to note that while these cyclical events have occurred in Earth's history, predicting or attributing specific catastrophic events to them with precise timelines is challenging. The geological and astronomical processes involved are complex and subject to various factors. Scientists continue to study these phenomena to gain a better understanding of Earth's past and future changes.
User Which of the above is most overdue?
ChatGPT Of the cyclical events mentioned, the Earth's geomagnetic field reversal is one that is difficult to predict precisely in terms of timing. Geomagnetic reversals occur irregularly, and it is challenging to determine when the next reversal will happen.
The last reversal, the Brunhes-Matuyama reversal, occurred approximately 780,000 years ago. Based on the geological record, reversals have occurred at irregular intervals ranging from tens of thousands to millions of years. Therefore, it's not accurate to say that a reversal is "overdue" in the sense of a specific timeframe.
It's important to note that the geological timescales associated with these cyclical events are extremely long, and our understanding of them is still evolving. While scientists continue to study these phenomena, predicting the exact timing of such events remains a significant challenge.
I believe there is substantially larger things to worry about. Yes, our environment is important, and barely a person I know doesn't believe this. If you want to fix it, stop using plastic (forever). Good luck doing that.
That nobody has yet figured out how to convert all the free carbon in the atmosphere into money is only a matter of time. Money will always trump whatever other bullshit gets swindled on any given day.
PS - the world was supposed to end many hundreds of times since the 70s due to global warming. It seems somehow we are still here. So maybe stop stressing about things you have little to no impact on.
If you are really serious about affecting anything, make the cows eat seaweed...
The formatting on this will be bad, but I just had ChatGPT generate this for me.

Please note that the examples provided reflect notable claims or predictions that have received attention, but the "Did Happen" column remains represented as a boolean, with "False" indicating that the specific claims did not happen. The list is not exhaustive and is intended to showcase a range of historical climate alarmism claims over the past 100 years.1. Teach: humanity has done X to the environment
2. Teach: if we don’t do something Y will happen
3. Conclude: I was not alive to do X
4. Ergo: the adults in my life did X
5. Ergo: the adults in my life will continue to do X which will cause Y because I can’t affect meaningful change
I don’t automatically assume they start at step 5 at school. I’ve seen his math homework. Is that a normal way of thinking though?
To automatically assume that with my son would teach him (likely, inadvertently) that what he learns at school may not be right (which isn’t true, for the most part). Rather I want to teach him that he takes ownership of the words that come out of his mouth. That his opinions are his own and he has to defend them, and further learn what is an opinion and what is a fact.
Wait, you don't teach him that?
This is a 100% attitude and filtering issue.
I don't want to teach my son that him misunderstanding something is someone else's fault. Obviously, this wasn't taught in class. He was taught lots of things and was a conclusion he came to on his own. Like nobody ever told me that a McDonald's hamburger will cost around $50 when I retire, I simply did some math based on the average inflation. Will it actually? no idea. But I know that I should probably have that much more in my retirement account.
No, pretty sure he concluded exactly what his teachers wanted him to conclude. Nine year olds are not famous for their critical thinking and deep research skills.

Do you know us IRL or something?
Our kids are worried about it, more so than our generation, that's for sure.
