The first humans to arrive in Australia destroyed the pristine
landscape, probably by lighting huge fires, the latest research
suggests.


Ever seen lightning hit a eucalyptus tree ?

Makes a real bright fireball real fast hurts your eyes to see , but the leaves seem to explode in white hot sparks , like the whole tree just went blue/white glittery sorta then goes orange in a ball of flame and there is almost a mini mushroom cloud of smoke goes up , and fire seems to fall from the tree like rain , burnng leaves and sticks I guess , falling off . These hit the dry leaves,grass and twigs under the tree , perfect tinder actualy and away it goes , I seen it happen a couple times now .

Have these boffins figured naturally occuring fires into their theory ?

I know that the burning was / is done to keep the fuel levels down and prevent lightning fires getting out of hand .

Its a big problem in the wheatbelt in West Au still at harvest time , the crops are tinder dry , the temps get up to 50 deg c , and we get electric storms come over , no rain butlots of lightning on tinder dry paddocks of grass ..... guess what that makes ?

I seen it happen over the scrub too the fires are much more spectactular .. We have been cut off at times almost ( I was lucky enough to know the backroads in the area ) when lightning began fires in front , behind and to the sides of us while we were traveling between Geraldton and Perth , just north of Badgingarra , shut the highway for a day almost till the fires burned out . It was kind of scary racing to get ahead of the fire before it crossed the road and locked us in .

In short , I dont realy buy their theory . the scariest and biiggest fires I have seen were not lit by people , but then this is now , they are tlking about way back when , did naturaly occuring fires happen then , or were they all man made ?

Not meant as a slight, but damn us humans have always been mucking
things up!

"Humans were influencing the climate long before the Industrial
Revolution, new research suggests.


But not on the scale or with the toxicity as was during and after the industrial revolution , pollution and environmental degradation on such a sale for so long a periods of time was simply not possible before .

Levels of methane rose steadily in the atmosphere in the first
millennium, according to an analysis of gases trapped in ice beneath
Antarctica.


Hell , that could even be from the 'great flood' of the bible , or any of the global floods told of in legend , even dream-time legend , inca legend Chinese legend ..... there be lots of rotting stuff after a catastrophe .

I was reading of the charting of pesticide leveles found in the antartic ice it was interesting , since the govt claimed that it couldnt reach islands 20 km offshore from the mainland .. yet its found way down there .

What was the acid rain like back then tho ? Water polution , was there such a thing as petroliom plumes inthe underground water then ? Pesticide drift and outgassing , was this an issue then too ?

Much of the greenhouse gas came from huge fires lit by humans as they
cleared land for settlements and farming, researchers report in
Science. "

Natural forrest fires didnt contribute tho ? amazing , I need to look deeper into this .

Maybe that global warming wasn't such a bad thing, I hate the F#$%in'
snow.
Perhaps we helped end the Ice Age.
I am reminded of the old saw, "todays solutions become tomorrow's
problems."

Maybe we did maybe we didnt . I watched a docco about "global dimming" , it combined global warming with someother theories and came up with a seemingly sensible answer , but the implacations of it were bloody scary too .

It was also a bbc docco , if you can get your hands on it , its worth a look .
