    I'm gonna guess that these were developed by Alfred Wegener to illustrate how the continents experienced different climates as they drifted around the globe.
    But maybe these are earlier than this...

    It´s a bit tricky - I will spoil that it is (much) earlier than Wegener - the map was intended to display what happens if equvalent landareas to modern continents emerge (not move) on other latitudes...

    Hi,
    These are figures from Lyell's Principles of Geology, at least in the 1850's edition.

    That´s correct - I choose it to illustrate the early ideas of climate change in the geologic past:
