In fact, I have noticed a strange anomaly this year.
Places which were experiencing heavy pollution, such as the SE of China, show up almost completely green now.
And, Northern Thailand is almost the same, but not quite as green.
This must be due to prevailing wind conditions which are atypical, this February.
Or, perhaps, due to colder air flowing into the region.
Or, some other reason...
This is obviously a welcome change for many, if not all, people inhabiting these areas.
I find it strange and unsettling, is all that I am saying.
I do not welcome the smoke.
I only find the sudden and unexplained absence of smoke, at this time of year, puzzling and unsettling.
