Retirement is coming. I gave my last class lecture today. Gave my first one in 1988, 35 years ago. Today was General Ecology and the topic was Global Ecology. I chose to look at how the Earth has changed since I first started lecturing. A series of Tweets --

But I also reminded my class today of positive changes that have come about from careful studies and social commitment. Favorite examples of mine are delisting of several Great Lakes AOCs (with more to come), dramatic slowing of invasive species in the Great lakes, and others.

Check out these 3D maps of lakes and human density around them.
PS I now have a version of the global density map with the Great Lakes cut out, plus other large water bodies e.g. Lake Victoria, Lake Baikal - was a bit fiddly to process but I now have the global file compressed to under 2.5MB

Love this! The most important and difficult thing a scientist can do is let data change their mind. The second most important thing is do it publicly because this is what separates science from other human endeavors and people need to know that.
Today my graduate student finished running experiments that demonstrated one of the major hypotheses of the lab was incorrect. The first thing I did was congratulate him on running well thought out experiments. The data is the data.

I'm just coming to this topic, but the new article in Nature suggests humanity's beginnings occurred around a paleo-lake similar to modern Lake Victoria, tens of thousands of km-sq, but tens of meters deep. No wonder humans love large lakes.
