I doubt if any bears are starving because of climate change (yet, that is). I also suspect this old guy is undergoing his seasonal moult. There is lots of silly climatic stuff on the media (eg no one has yet been driven off their island because of sea level rise - yet).

Looks like more shock tactics to me?goldierocks said:
I recently read an article that was discussing that 30 years ago climate agencies were projecting that whole groups of islands (such as the Maldives) could/would be under water by now. Apparently water levels have only minimally increased & none are anywhere near being or becoming under water
Funnily enough some of these same agencies are still projecting this but now in the next 15 years. There are definately changes occurring but I don't buy the full extent some try to sell us.
Awareness, clean technology & limiting/reducing fossil fuel use (but not removing it altogether) seem to me to be more logical ways forward.
Climate change is fast becoming a topic that for forums & pubs should be bundled in with religion + politics IMO. :argh:
There is little doubt that some islands will go under, and Maldives are near the top of the list. Sea level is constantly rising - no doubt about that - but at present rates of rise it will take 330 years to rise one metre (assuming no increased rate - not expected but possible). However some areas such as the Maldives or Carterist Islands are only a maximum of 75 cm above sea level.

The RATE issue is what is being left out of a lot of the scary prophecies. Partly because there is one rate that will take a long time to reverse - the co2 and resultant warming (ie sea level may take a long time to rise but it will take a lot longer to reverse).
I don't think we should ignore the issue, but we need more honest and rational debate on it - and I suspect we will just have to adapt to at least some degree.

Lived at the same house for 20yrs.The last 10 acres are very close to sea level .(Runs along the pumicestone passage)...The first 15yrs was not a problem. Now on king tides the last 2 acres go under water sometimes up to a foot depending on tide height...So something is happening. You are not aloud to build a low level house out here anymore. :8
Can be various reasons - rise over last 20 years is about 6 cm at most. Other things that can cause it are land subsidence (just as common, even for Pacific Islands - and ask people in Venice) and changes along the coast (eg building Portland terminal devastated land to its east - houses I used to party in have gone completely around Dutton Way). Restrictions on building make sense for the future.Smoky bandit said:
Sea level rise has been constantly rising for centuries and has probably speeded up - but is still around 3 mm per year (was perhaps 1.8 mm per year). However if one is very close to sea level, you become increasingly susceptible to king tides and mini-tsunamis long before you are finally inundated (30 cm high tsunamis occur almost daily). Photo is Maldives town during a 30 cm tsunami - water through every street. So in 100 years they will be in real trouble.
The point I was making is that the media tend to focus on those who purposely don't mention the RATE at which things occur ("the sky is falling"), and those who simply say that such things are not occurring (when we have accurate measurements showing that they are). It blurs what is URGENT and what is less urgent (all is IMPORTANT in the scale of 100-300 years - eg in some parts of Australia if your grandchildren inherit your house they may not be able to sell it when they get old - and the main urgency is that if we cannot drop CO2 emissions - which we can do in tens of years - it will take hundreds of years to reverse the situation).
Climate was never constant - it has been warming steadily for 17,000 years and we have happily ignored the fact - since the industrial revolution we appear to have significantly increased the rate of warming so we have to stop ignoring the fact that nothing in life is constant.

I'd like to dispute the 'fact' that CO2 is the cause of global warming as is being touted repeatedly as being 'scientifically proven'. It has been analysed (by scientists) that for the past 300 million years, in every instance (bar one) of cyclic warming/icing the warming has PRECEDED the increase in CO2. So how can it possibly be the CAUSE of it?
I agree that mankind has been crapping in his own nest for too long and yes, the increase in CO2 is a concern and should be addressed, but please don't feed us the BS that is currently being rammed down our throats!
With reference to sea levels rising causing flooding of the Pacific Islands, it has been proven that some of the Marshall Islands are actually sinking, so unfortunately people are only quoting information that suits their own agenda.

i moved to Tasmania for a few years back in 1990 and there was a scare campaign put out there that the Bass Highway would be under water within 5 years, almost 30 years later i'm still waiting.Anolphart said:
One volcanic eruption puts out more carbon dioxide in one eruption than man could produce in decades.
Too many failed university students out there looking for their big moment... they had to pick climate change.. another failure, sad.
Their problem is they've never been out of the big polluted cities, they can't see the stars at night. Pollution is not climate change, spend some time in the bush, do some detecting, look up at the night sky, be amazed.
Have a look at the ice retention rates as well as the maps showing the historical areas where sea ice had been formed and how long before it thawed. Less pack ice around the artic and antartic result in sea levels rising. Anything thats done now to reduce emissions and harm to the environment will just slow the inevitable, its the cycle that the earth has been on since the beginning of its existence what were doing is just speeding the process up by a few thousand years. People tend to forget that the time they spend on the earth is comparable with a grain of sand on a beach compared to the overall time since the earth was formed
Here's one for yuou to digest,
The atol group called Kiribati has often been used as the example for sea levels rising.
The island of Tarawa had a causway built to a neighboring island by the Japanese government as a goodwill gesture because of some actions taken i ww2.
The trouble it caused was that a low lieing small sand island in the bay, washed back into the sea because the gap between the two island was reduced from hundreds of metre's to about 50 metre's .
This had the same effect as pulling the plug out of the bath.
It quickly washed away the small sand island due to the erosion.
The tide heights have Not changed on the rest of the atol but the greenies still misuse these islands as proof.
Change there is , but co2 is a minute cause if any.
They seem to miss all the other gases which are more destructive and up to hundreds of times the volume of co2.

I am no scientist but am suprised no one seems to take into account the trillions of tonnes of sediment that is washed into the oceans via our rivers, dust storms etc. Wouldn't that have an effect ? Maybe compare that to the hight and mass of growing mountain ranges like the Himalayas ? Do they offset each other evenly ?
I was always of the understanding that the earths crust was a constantly evolving, moving platform, with land rising and falling across the earth surface and therefore there will be changes in sea levels, tidal movements etc on a constant basis.
Classic examples of what can happen with land mass, just build a groyne from the coast out into the sea, with tidal movement watch sand that has been deposited over many thousands of years disappear and the coastline erode due to tidal influence.
Adelaides beaches are a classic example of this, hence our government spends millions pumping and trucking sand along the metro coastline.

You can't stop on the side of the freeway in Perth without getting bogged in sand. Drove 200 klms east of Perth into the wheatbelt and got bogged on the verg!!!Goldfreak said:Maybe Perth could help us out. They seem to have plenty of sandManpa said:
They build houses on that stuff. Just waiting for an earthquake (subsidence). wow.
I remember the stink driving down to Edithvale on Springvale Rd. PHEW!!!
Put all your toys in the bath and the water level goes up , so think about how many boats man has in the ocean , plus they stopped whaling and dubia has built citys where the ocean was plus hawaii grows from lava flowing into the ocean.
Goldfreak has a very valid point about the trillions of tons of sediment that has made its way to the ocean.
Also when i freeze water it expands so if the icebergs have most of there volume under the water line melting them should not take up anymore space then there expanded form .
Climate change started well before the dinasuars and the middle of Australia was cover by ocean.
