Sunspots reaching 1,000-year high

AI Thread Summary
A recent analysis indicates that the Sun is currently experiencing higher activity levels than at any point in the last 1,000 years. Researchers from the Institute for Astronomy in Zurich utilized ice core samples from Greenland to reconstruct historical solar activity. Their findings reveal a correlation between the increase in sunspots over the past century and the gradual warming of the Earth's climate. This warming trend is further exacerbated by greenhouse gases emitted from fossil fuel combustion. The implications of this research highlight the complex interplay between solar activity and climate change.

A new analysis shows that the Sun is more active now than it has been at anytime in the previous 1,000 years.
Scientists based at the Institute for Astronomy in Zurich used ice cores from Greenland to construct a picture of our star's activity in the past.

They say that over the last century the number of sunspots rose at the same time that the Earth's climate became steadily warmer.

This trend is being amplified by gases from fossil fuel burning, they argue. [continued]

Very interesting article Ivan, thanks!
 

Thread 'Could an external cosmic body have influenced Earth’s geology?'

Hello, I’m currently writing a series of essays on Pangaea, continental drift, and Earth’s geological cycles. While working on my research, I’ve come across some inconsistencies in the existing theories — for example, why the main pressure seems to have been concentrated in the northern polar regions. So I’m curious: is there any data or evidence suggesting that an external cosmic body (an asteroid, comet, or another massive object) could have influenced Earth’s geology in the distant...

Thread 'The Secrets of Prof. Verschure's Rosetta Stones'

(Edit: since the thread title was changed, this first sentence is too cryptic: the original title referred to a Tool song....) Besides being a favorite song by a favorite band, the thread title is a straightforward play on words. This summer, as a present to myself for being promoted, I purchased a collection of thin sections that I believe comprise the research materials of Prof. Rob Verschure, who at the time was faculty in the Geological Institute in Amsterdam. What changed this...
