The Climate, Environment and Energy Thread

[LP]

Note that the “Little Ice Age” almost overlaps with the period that Port Phillip Bay was dry land so while it was colder in the northern hemisphere, southern Australia was experiencing higher evaporation rates.  That does suggest warmer temperatures but a much larger part of Australia was arid during the Pleistocene as more of the water budget was locked up in ice caps and glaciers.

Yes, this correlation between ice caps and dry hot periods over low latitudes is frequently overlooked in climate sceptic debates. The general public's assumption is that hot means dry, when history indicates you need more ice at the caps to be dry at low latitudes in the absence of some other effect.

Just An FYI for some readers;
Low Lattiudes are near the equator, +/- 0° north or south, High Latitudes are near the poles, +/- 90° North or South. Be careful when reading about High and Low latitudes, because a term like "Down South" doesn't mean at a Low Latitiude!

Sometimes I think modern scientists should throw out the historical deference to old terminology, some of the terms used in this case were originally phrased when the debates over the earth being round, flat or hollow were still underway!
