marshlands and estuaries are wierd concepts that depending on the author can be interpreted as land or as see depending on the person making the interpretation

also todays coastlines have clearly been changed by human action the aral sea desert the pakistani coastline continous recess all cause by damms for agricultural use

as for the sahara rain forest disapearing without human action thats bogus ever since the appearance of agriculture that a culture of burning up a place to make it suitable for agriculture exists i mean if humans turned australia into a massive desert by doing this and overhunting you mean to tell me that the same didn´t happened in the sahara ? the poeni agriculturalist practics made far more temperate areas of north africa into deserts then other areas less forgiving that where inhabited by the garamantines wich managed to keep those areas fertile until the 17th century (last time the sahara gained large tracts of land over the humans )

as for if this was a cooling period you can go and read the 70´s and 80´s articles on global cooling that was scaring everyone we live in micro periods so even if in a micro period (30-50 years) it might seem it´s going on one direction the trufh is that it might actually go in the opposite direction

climatologists don´t know whats trully going on atm with our planet atm all they keep discovering are mechanisms that the earth has to regulate itself like over eating and the trees free carbon dioxid that trees are growing 30% faster then 50 years ago and how does the heat and carbon that keeps going into the north atlantic carbon drain hasn´t turned the sea water acid yet some defend that new micro organism will develop (absorbing the carbon) others defend that it will stop the ocean chain but in the end they don´t know all they know is mechanisms and that we have passed the amount of carbon in the air that ever existed on earth before

only the study of the oceans is far more complex then what people imagine much more the wider area of all climatology some dudes defend the dumping of iron in the pacific to feed organism that can suport the water acidity and can use that carbon to create shells others defend that it will kill the sea cause it will allow the expansion of poisenous algae and jelly fish so if you wanna be honest what you can trully say is that we don´t know but the clues aren´t positive and yes we humans have a big hand on it mercury in the atmosphere acid and trash and toxics in the streams

just for example go and search the effects of bisphenol a in the gender atribution in mamals and how just a litle plastic can screw up an entire eco system and then multiply that by the thousands of chemicals we create and unleash on the enviroment without knowing it´s effects ofc humans have no impact ...

sorry if the tone might seem agressive but sometimes i can still feel the flame lighting up luckly it doesn´t go off as much as in the past
