AI Thread Summary
Global dimming, a phenomenon linked to pollution and industrial activities, particularly in regions like Southeast Asia, is causing a significant reduction in sunlight, with some areas experiencing a decrease of up to 20%. This reduction in sunlight has implications for global warming, contributing to droughts, such as those seen in Africa during the 1980s. The discussion highlights concerns about the impact of decreased sunlight on solar energy production, agriculture, and forest growth, raising questions about future oxygen supply amid ongoing deforestation. While some participants note that the U.S. has more forest land than in the past, the overarching concern remains about the broader environmental consequences of global dimming and the need for a balanced approach to address these issues.

As we know about global warming , how many of you have heard of global dimming? As you may well guess, it's all to do with the pollution effects of sunlight over the whole world, particularly in places like south east asia where there is a hell of a lot of coal burning and eccesive factories burning toxins. The worst culprit of all is probably high altitude aircraft. In some places around the world the sunlight has fallen by 20% due to all this crap in the atmosphere. This has also accounted for drought back in the eighties in Africa as rainfall has plummeted. It goes show just what global warming is doing and the balance must be restored.

I guess we have been there and here too. I'm not sure if all those conclusions about drought are all that accurate. It may all be a wee bit more complicated.
 
Your name is exactly the same as mine only mine has an " I " on the end.
 
I havnt read a lot about the isse "global dimming" but sunlight is decreasing think of the problems that will create. Less energy for solar power. Decresing farming and tree growth, added to our current problem of rain forests being cut down at alarming rates. Where will get get our oxygen?

Solar power? How much solar power are we getting now?

In the US, there's more forest land then there was back around the Native American times.

We'll get our oxygen from the air! :confused:

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...
