I'm sick of hearing GLOBAL WARMING AGGHHH

Yes I guess oil will run out in the future some time that has been known for some time. Look on the bright side when it does run out, NO MORE C02. Life will surely be different when that happens

Sadly, it will make it worse. Once we have peaked in oil production, demand will outstrip supply and we'll burn just about everything in an attempt to replace oil. Coal is 70% carbon and we will replace oil with coal.

I thought from the ice cores somehow :?

That'll slow the hoons down. :D

That and tree and coral rings.

$5 a litre will do that too.

I think Waldo's idea is more plausible.

Careful Rod, you're weakening...

There is no doubt that the human race has the power to do something about it. A short journey through our short history will show that we are able to react quite well when a threat is recognised to enough of us.

Now, hypothetically, looking back on the present from the future, (and lets just pretend that we already decided it is happening): the real risk is, will we recognise the threat before it is too late to modify our collective behavior to do something about it?

The problem with managing such a large system as the climate, is that there is no on/off switch. As the ozone hole experience shows, there are big measuring sticks required between the action and the re-action. The sooner, the better IMO.

I'm not much of a ring studier myself but some scientists are.

One way that paleoclimatologists unlock the secrets of ancient climates is by studying the rings in certain types of trees, such as the redwoods and giant sequoias found in California and different varieties of pines. As a tree grows, it adds a new layer of wood to its trunk every year. This forms a ring, and the age of the tree can be determined by counting the number of these annual growth rings.

The science of predicting the 'when', 'where', and 'if' of global warming is uncertain. Our weather systems are so complicated we can't always work out what's going on. In the next issue we will look at how scientists use all the information they collect about the weather to predict what climate changes are likely to happen.
TREE thermometers

You can do your own research into climate change. Find a tree stump, a log or even a thick branch and have a look at the rings. Remember: the wider the ring, the warmer the temperatures in that year.(Hint: pine trees have the best rings).

If you're into tree rings, pine trees have the best. :)

I got as far as "FACT SHEET TEXT" in your link.

Coming from the Australian government, thats an oxymoron.

Scientists see it in tree rings, ancient coral and bubbles trapped in ice cores. These reveal that the world has not been as warm as it is now for a millennium or more. The three warmest years on record have all occurred since 1998; 19 of the warmest 20 since 1980. And Earth has probably never warmed as fast as in the past 30 years - a period when natural influences on global temperatures, such as solar cycles and volcanoes should have cooled us down. Studies of the thermal inertia of the oceans suggest that there is more warming in the pipeline.
Climatologists reporting for the UN Intergovernmental Panel on Climate Change (IPCC) say we are seeing global warming caused by human activities and there are growing fears of feedbacks that will accelerate this warming.

:trumpet: This a public service announcement. :meg:

People of the world..................

Stop typing on your computer about global warming, the energy used by your computer isnt helping with the global warming.....you are the cause of it.:death:

End of announcement.

Al :hmm:

Sorry Al, it's either that or surf for .
