Ancient tools, buried for millions of years in Kenya, may be the oldest example yet of our ancestors' technological prowess. The tools, recently discovered on the Homa Peninsula in Lake Victoria, are now the earliest known examples of Oldowan technology — stretching its known start date back by as many as 400,000 years.

3 million years?! Using tools?!

Sure they had almost 4.5 billion years to learn how to make them
Civilization has risen and fallen many times on this planet. We happen to be crashing back down right now.
New discoveries keep pushing back the date for the start of civilization.
It all depends on how you define "civilization".
Civilization has the same root as city.
Not sure of your comparison, but maybe.....
They all went to Guam and it tipped over.
That first spike in temperature, called the Bolling-Allerod, coincided with melt water pulse 1A which raised sea about 100 feet. Then the temps dropped back to glacial maximum levels followed by another tremendous rise in temps which coincided with melt water pulse 1B that raised sea levels another 45 ft. and by the time the Holocene had begun sea level had risen 400 ft.
A Dryas is a little bitty Arctic flower so if you find one you can certainly pick it. :)
I tried the link you posted in #20. It doesn’t open for me because it’s a paysite. Useless.
You get free articles and it works for me in incognito, and 3 different browsers.
If you have already used your free articles then you should block their cookie, or at least remove it occasionally.
Not useless at all.
Thanks! I’ll see if I can find out how to block their cookie.
Some sites actually block you but most sites that give some free articles can just have their cookie blocked so that you always start at article one.
If you use chrome then click on the lock, up by the web page address, click on cookies, and block and remove the site’s cookies.
Occasionally blocking the cookie is too much so you can block it, then click on “blocked cookies” and click on remove when leaving (or whatever the phrasing is).
Thanks again. I use Firefox but it looks like it works the same. I thought my VPN was supposed to block cookies. Guess I’ll have to recheck the settings on that.
It was a hassle for you tonight but the more you play with that then the more you can get past some site hassles.
Something else I do is use the Quick java Script switcher extension and click, and then unclick it, and that stops some sites from blocking your scrolling down and reading the article.
I don’t understand how it all works but playing with it all does open up sites for you.
Well, you may have just unleashed a monster on paysite journalism sites. :)
I’ll try to get outside the box and work my system more than I’m used to doing.
There were a few cataclysms that happened in that time which practically wiped out people. But I don't think these were true humans. They were missing what we have today...God's revelation.
Re: Not exactly slowly
I was referring to planetary average temperature.
Greenland is an outlier that has radical temperature changes based mostly on tropical and Arctic ocean currents.
Thank you for the excellent charts.
I have not seen them before.
The Greenland ice cores are a proxy for average temps of the Earth. If average temps in Greenland rise 18 C it’s pretty much a certainty they’ve risen quite a bit everywhere else though not necessarily the same amount.
