from the article : Northern Arabia 7,000 years ago was very different to today. Rainfall was higher, so much of the area was covered by grassland and there were scattered lakes.
A larger farther out picture would help. I flew all over Iraq during the 2nd war and it has some interesting geography. Like where the Tigris and Euphrates come together before the Persion Gulf is all wetlands... The people there scoot around on little boats.
Yes. My Kurd friends in N. Syria told me that the garden of Eden was in that general area where the Tigress and Euphrates Rivers merge (think it is near Raqqa). Noah’s Ark, they say, is in the mountains near there.
And the last villages where they still speak in the dialect of Aramaic that Jesus spoke are near there.
Some of the best (if not The Best) olives in the world grow in Efrin (Afrin) which was stolen by Turkey and ISIS. Fruit trees of many kinds grow there, but it is being hurt by Turkey bottling up the rivers to prevent them coming into N. Syria.
I am skeptical of archeologists who say they know what the climate was 7,000 years ago. A the best it would be a wild a$$ guess. Like the computer predictions for the Covid19 virus. A lot of BS.
