Not at all LW - reckon we're singin' off the same hymn sheet.

Yep I agree BC.... Everything I have read says they are new , but im wrong again... Should have read better books I think...

Goldierocks,
If the Malenkovic cycle you mentioned previously (a change in the earths orbit) also includes a shift in the earths axis so that over a few million years the axis of the Antarctic is somewhere over the Southern Ocean, why wouldn't everything be frozen and the ice-caps re-form?... given that the sun only appears on the horizon for a few months of the year and the winter temperature averages -67 degrees Celsius.
I just can't see lush forests that far from the sun, even if it was on the continent, polar bears maybe.. :sunny:

I believe the "experts" are wrong but i hope they are right so i can grow my own bananas
Not necessarily - but I have seen many examples of people actually believing such things (dog-paddling bear cubs etc).LoneWolf said:That pic was just meant to show a point and ... Do you think im that stupid to think a dumb bear would stand there till the ice around him melts?

There is plenty of good evidence for the warming (in fact that the Arctic is warming faster than elsewhere). But it is fairly dry and boring scientific data that does not sell newspapers, so you wont read it in the popular media.LoneWolf said:Yep I agree BC....

There is some wobble in the Earth's axis related to the Malenkovic cycles, but it is not as extreme as that. I guess you cant imagine such extremes because you possibly had not even heard that this has occurred in the past - it is outside any experience that either of us have had. But we have techniques that tell us that the Antarctic was in the same polar position in both warm periods and ice-covered periods. We know that the cold beech forests that only exist in parts of Australia now (eg NE Tasmania), extended to Broken Hill only a million years ago (humans prior to **** sapiens were already around 4 million years ago). We find fossil marsupials in Antarctica. We find rocks called laterites characteristic of warm intervals in Siberia.EVIE/BEE said:
You seem to be ascribing ice caps to lengths of days and sunlight, but they require much more than that. We are in an ice age and the Earth is usually not in an ice age but much warmer (6 degrees). Malenkovic cycles appear to be important in flipping us in and out of each glacial and interglacial cycle (of the present ice age), but this is only one factor - carbon dioxide seems to control temperatures (warming and cooling trends) once a cycle has started. Latitude is an important factor as you say, being colder near the poles than elsewhere (but colder is not always the same as icy). Interiors of continents show more temperature extremes (I have been to a place in Siberia where winter temperatures of minus 72 degrees Celsius and summer temperatures of plus 42 degrees Celsius have been recorded). The flow of air (winds) and ocean currents is also a factor - the Antarctic ice cap only developed after the separation of Antarctica and Australia, which permitted westerly winds and currents to isolate it thermally. So no one cause.
Although the present warming has very potential very negative impacts in the future, it is worth keeping in mind that without human-induced warming, we would have soon gone into the next glacial period. In 25,000 years we would have had to all retreat to the equator and much of Europe, Asia and North America would become covered by ice kms thick where no human could survive. This happened to humans during the last glacial period (although the aborigines were able to exist in warm Australia for 50,000 years without interruption, in Europe people had to retreat to areas like Spain and the Levant, and could only re-populate Europe again10,000 years ago. The difference was that plants and animals had tens of thousands of years to adapt, whereas with the present warming they may have too little time (hundreds of years).
Forests extend to more than 60 degrees north at present and the Antarctic Circle is at 66 degrees (south). The poles do not get sun only a few months of the year, they get equal months of sun and darkness, so the sun does not go down in summer (I had to cover my head to get any sleep in summer). In fact the North Pole gets 100 hours more daylight than the equator. And of course high latitudes have deciduous trees - their leaves fall off and they do not grow over winter, so darkness does not worry them. Plants still grow into the Arctic circle - one major reason for no trees is that the ground is still frozen from the last glacial period, so tree roots cannot penetrate the still-frozen ground.
Well I just googled 'Dog Paddling Bear cubs' and Yes they do dog paddle.. The first 12 'items' says they do and im sure many others do too. in a bear like way... up to 10kmh too... :koala:

Well no, these are not my opinions, but those of scientists who study climate. I don't think it is condescending to state what the scientists believe - the scientific evidence. What other evidence is there for the science? Wouldn't it be as valid for me to say that you are condescending when you refute the scientific evidence using uninformed media sensationalism and speculation? However I would not be so rude to you, because obviously most people don't read scientific papers and therefore cannot detect the fabrications of the media. I thought those reading might want to know what scientists actually have evidence for - we all see the media reports.goldierocks said:
I do not claim to be an expert - however I am an Earth scientist who has written papers on palaeoclimate, who reads the relevant scientific literature, and who has worked in the Arctic of Canada and Siberia over a number of years. So I have a fair knowledge of the science (and of plants, animals, daylight hours and ice cover of the region through daily observation over that time). I also teach human evolution and how humans have been affected by climate change throughout time, and I have dated ancient humans and the rocks of the past.
I meant that I did not think you or anyone had to be stupid to think that (even if you did) - anyway I'll bow out now, as there seems to be less interest than I had thought.LoneWolf said:goldierocks said:Not necessarily - but I have seen many examples of people actually believing such things (dog-paddling bear cubs etc).LoneWolf said:That pic was just meant to show a point and ...

I am interested in the science. Its hard to get your head around such a complex thing as the earths climate and what is causing its change let alone sea level rise, beyond basic things like, the sea levels are rising and the earth is getting warmer. There is an endless amount of data supporting or refuting the rest of the narrative, most of us side with the data supporting what we already feel is true.
This day and age you can find graphs ,studies ,pictures and scientific opinions to prove both sides of any arguement, trust nothing.

Just wait till the solar system plunges through a hydrogen cloud in space.... probably the very space around us will be aglow with light..... and it may well just rain for 40 days and nights.... or more. Afterwards as the atmosphere adjusts and we cast off that which we cannot hold and the waters receed we may well be only a few waterlogged specimens to start anew. Be plenty of light at the poles on the way through the space cloud though hey !
wonder how good they are at seeing space clouds... or would we just see straight through em.... bugga's get a fright when they spot a new near earth object ..... who's gunna spot a little blobby cloud out beyond the solar systems reach
