What happened back then?

[D2Cat]

Approximately 6,000 years ago, the Sahara Desert was characterized by a rich ecosystem comprised of lakes, rivers, and expansive grasslands, which supported diverse wildlife and human populations. Research conducted by the U.S. Geological Survey indicates that this fertile environment began to undergo significant transformation around 5,000 years ago, coinciding with alterations in Earth's orbital patterns that precipitated a marked reduction in precipitation levels. Consequently, the region experienced a process of desertification, leading to the arid landscape that is recognized today. This pronounced ecological transition underscores the impact of Earth's natural cycles on environmental conditions and the human civilizations that once thrived in those habitats.


Its called climate change and we don't cause it nor can we stop it. The elite want to make money off it by making us suffer.

Desertification of the Sahara was also helped along by extreme overgrazing by the local people’s livestock. This occurred in more recent times.

All caused by the camel dung used for fuel!

see ! it IS man made climate change !!!!

If only they had made the switch to electric camels everything would have been good and we'd be enjoying margaritas on the Sahara beach watching the whales swim by.

Nevada is a prime example of climate change....12,000 years ago Nevada was largely under the waters of prehistoric Lake Lahontan. It took only about 3000 years for that to dry up and turn Nevada into the desert it is now. Not too many people living in Nevada back then to cause climate change.....

Now all we have left of that huge lake is giant dry lake beds everywhere:

Now things seem to be changing again. The last few years we've had around 30% more precipitation each calendar year compared to the past 100 years (at least in my location).

re: Not too many people living in Nevada back then to cause climate change.....

yeah, gotta blame it on the dinosaurs pooping in the water !!

saw a bit on how 20 African countries are trying to make a 'line of trees' to stop the Sahara from heading south... I applaud them for their effort !!!

Being a practical person and skeptic with at least half a brain still working I’m thinking that if the unprecedented rise in CO2 and methane we know we have released is ignored and the science folks are right we F ourselves by doing nothing. If they are wrong and we mitigate we get cheaper electricity, cleaner air, fewer stripped out land sites, and preserve the fossil fuels for a time when we can know they are safe to use. I just hate to bet against the possibility of disaster when it looks like we might be able to plan to deal with it if it happens. Kinda like owning a house in Altadena and saying it can’t happen here. Poor folks.

It seems that according to the NEW Biology101 courses, tress no longer breath in CO2, exhale O2 AND store Carbon.

THAT'S the problem..... at least according to scientists and politicians and the GW/CC crowds....

That’s not true. Where did you hear that nonsense? Biology 101 does not teach that.

What about women?

 

[GreensvilleJay]

well 'they' seem to think so, why else would 'they' NOT be planting a zillion trees and ELIMINATE the 'CO2 problem' !
frankly after reading what some 'scientists' are promoting as the truth, they're now about 3 rungs below 'politicians'.

I'm beginning to understand what Political Science graduates do, I always wondered what was scientific about politics.

The problem with your information is not the information, it's the outcome you present. It's is true the earth goes through climate shifts and has for close to 4.5 billion years, without humans. So you can graph these patterns and see changes. What we see is the change above normal climatic patterns over the last century, with a shift above normal of 1.5°C.

Now I'm just an average person with 2 degrees in Earth Science and 33 years of experience and data on this topic. The question is not that humans are causing it, we are. The question is how are we going to deal with this in the future. We as a species have lived in both colder and warmer climates, just not with the added bonus of overpopulation and massive amounts of toxins. Take the test on how much plastic is now in your body......

Now this may not change your mind, it will probably cause you to firm up your own beliefs.....I see that all the time. Know that not everyone who owns a tractor thinks the same things.

Peace...

One problem I have is the accuracy of the numbers scientists come up with. Just HOW do they KNOW what the temperature was 1000,5,000.,10,000 ,100,000 years ago ? Heck, how accurate were mercury thermometers in the 1800s ?
According to their numbers ,east coast of USA is supposed to be underwater ......
Lots of examples.... 'man made CO2 bad, volcano CO2 is GOOD ??' I KNOW that planting a 'zillion' tress WILL reverse the man made CO2 problem..
I'm surprised someone in a white coat hasn't already calculated the increase in hazmat to the east coast from the LA fires......

Great set of questions..... Without going into a long drawn out lecture I will address accuracy and temperatures. First, there are small ocean animals that live in a certain range of temperatures. Others live in different ranges. If you look at lake or ocean sediments you can find them. Carbon date the samples and you will get both temperature range and dates. You know carbon dating has a plus or minus 2%. So a date maybe 10,500 yrs. +/- 225 years. Ice core data traps tiny air bubbles which can be analyzed for atmospheric gasses. Put the two together and you can get a good idea to what was going on and when.

Now the whole good/bad thing boils down to the ability for the earth to "carry" what's on it. The carrying capacity of the earth is approximately 9-10 billion, depending on your source. We are 8.2 billion as of tomorrow. We are seeing resource conflicts and mass migrations of people from areas that cannot support them. 153 families, climate refugees, had to move from southern Louisiana because of sea level rise. This was reported in the wall street journal.

Trees are an interesting idea. A study conducted more then ten years ago looked at population and the amount of trees per person. In the 1780's, based on historical data of world Forrest cover, was approximately 32 trees per person. This was the last decade nature could keep up with the amount CO2 produced by humans. Today number is single digits and shrinking fast.

A personal friend of ours, noble prize winner, in chemistry for her work in climate studies came over for dinner. One simple fact came out at dinner, that night. People can and do alter their surroundings. More people, more alterations.

In the long run we will find it easier to challenge the data then look at our own actions. I'm not pointing figures, hell I drive a f350 with the 7.3 gas engine and 4.30 gears. I'm I doing my best to address this issue? NO. How about my nonemission b8200? Nope. What I do however is realize is we are changing our climate. I'm a scientist, I question everything. Having a good dose of scepticism is a good thing to have. Even the most conservative of my friends mine agree we are. They take issue at how we want to "fix it"

 

[GreensvilleJay]

Well it's great to want to fix it, BUT...when you keep buying stuff from China, who DOESN'T want to fix it, well 'Houston ,we have a problem.We( Canada) could stop 100% of our GHG polution, China outputs that amount ,what every week ? Hard to get real numbers but they do commision a coal fired plant every week or two.....
As for 'trees', I've tried for 3 decades to get someone either the feds or provinces to run a program(self funding, no taxpayer money needed) to 'reduce wildfires' that would MINIMIZE loss of trees, MINIMIZE loss of structures, MINIMIZE loss of life and gee, save MILLIONS of critters that live IN those forests...simple, easy to implement, creates jobs, etc.. have never, ever received an acknowledgement form the 20 -25 emails over those 3 decades. If LA had implemented this ,they would not have lost 15,000+ homes, 50+ lives, 100B$ in 'losses'.

Just because something CAN be done,for the better of all, doesn't mean it WILL be done.

In the meantime, I'm trying to figure out why 2 pilots tried to land on 19, without 3 green.
