4. "Who's to say a warming planet won't be better for us than a cooling planet?"
My god man, there is so much research that advises to the contrary it is simply amazing that you would embarrass yourself by saying this.
Scientific consensus changes often. It wasn't so long ago that scientists were warning about a new ice age in the future. It would be beneficial to avoid an ice age if possible. A warmer planet would have several advantages. Frozen parts of the world like Siberia and Antarctica could become fertile farmland. Longer growing seasons in other areas may result in increased agricultural production. The northwest passage would open up sea transportation routes improving transport and commerce. Less energy would be needed to warm homes in currently cold countries.

Yes, a warmer planet would have many disadvantages too, but likewise there would also be many disadvantages to a colder planet. Who is to say the current temperature of the Earth is its 'optimum' temperature and that we should do whatever we can to keep it at this temperature? The temperature of the Earth has always fluctuated and will continue to do so, regardless of human intervention.

5. "Just let the climate change and adapt to the changes. We can't prevent them."
Now THIS is interesting in relation to future property prices. How do you see prices moving in relation to this adaptation. Please comment in relation to not only sea side properties and flow-on effects but also impacts on income, food prices, relocation costs, etc.
This has nothing to to with house prices. I don't see much of a link - certainly nothing that will impact house prices to any significant degree in my lifetime.

2. Residential property loans regulated by NCCP Act. Banks can't margin call unless borrower defaults.
3. Housing is second highest taxed sector of Australian Economy. Renters subsidised by highly taxed homeowners.
4. Ongoing improvement in housing affordability. Australian household formation faster than population growth since 1960s.

This is hard for me to say but...
Good post - I agree with Shadow.

Climate change has occurred throughout the Earth's history due to natural causes, and this continues today.

However today we also have humans contributing to climate change. I agree with that.

The question is, what proportion of current climate change is natural, and what proportion is human?

It is 95% natural and 5% human? 50/50? Who knows? Nobody knows.

I agree that we should reduce emissions, but I think we should do that in order to improve measurable indicators such as air quality, salinity, water quality etc. I don't think we should do it to 'prevent climate change' or even 'reduce climate change'. Our impact on the climate can't be measured, and we can't prevent climate change regardless of how much money we spend trying.

For example, we could spend billions trying to reduce global temperatures, and then measure the temperature in 50 years to find it has risen by 1 degree. How much of that was caused by the billions spent? Was the money wasted? Nobody knows. There is absolutely no way to tell what proportion of climate change is caused by humans.

Climate change has always been with us, and I suspect man's impact on the climate is tiny compared to the natural forces that have always caused climate change. Instead of spending huge sums of money trying to stop the climate changing, perhaps we should spend that money on ways to adapt to the inevitable change. We can't prevent it. We should adapt to it instead.

The climate has been influenced and changed throughout the earth's history.

There are two categories for the changes; human and natural.

The natural causes are things like volcanic eruptions, ocean currents, changes in the earth's orbital and solar variations etc.

There growing rate of change in concentrations of greenhouse gasses in the atmosphere has been unprecedented. This corresponds to the observations and empirical evidence of climate change.
OK, now we're getting somewhere.

This was the post I was referring to earlier , sorry I should have highlighted it.

There has been mention of what part of greenhouse gas has been from natural intervention and of human intervention.

My question is , is the human not natural and all that he does is a part of his nature , so in effect all causes of green house could be described as natural. Sorry

to throw confusion in , just wanted to make the point rather than ask the question .

For a good summary of the current science (and there are several dimensions / aspects to climate science) have a look at this pamphlet from the Royal Society: http://royalsociety.org/uploadedFiles/Royal_Society_Content/policy/publications/2010/4294972962.pdf

For Aussie property bears, "denial", is not just a long river in North Africa.....

That's typical false logic. Attack a point of view (i.e. the view that climate change is a bad thing for human beings) by attacking a statement that sounds ridiculous (i.e. that the current temperature is 'optimum') but that no-one actually said.

No-one is saying that the current temperature of earth is 'optimum'. What people are saying is that if the temperature increases enough it will have serious consequences for life as we know it, which is adapted to a particular temperature range.

Seems that the climate change proclaimers are having doubts :lol:

WIDELY-HELD assumptions that climate change is responsible for an upsurge in extreme drought, flood and storm events are not supported by a landmark review of the science.

Review fails to support link to disasters, not climate change. Don't be fooled by the bias of The Australian or the cherry picking of information. This isn't news.

Having said that, glad you are open to people changing their mind. Here's an article you might like;

And more information for those feeling open minded...

Of course climate change is 'real'. I don't think anyone here is claiming the climate is not changing (as it has always done).

The real question is how much of that change is natural and how much is caused by humans. Nobody knows the answer.

Australian Property Forum is an economics and finance forum dedicated to discussion of Australian and global real estate markets and macroeconomics, including house prices, housing affordability, and the likelihood of a property crash. Is there an Australian housing bubble? Will house prices crash, boom or stagnate? Is the Australian property market a pyramid scheme or Ponzi scheme? Can house prices really rise forever? These are the questions we address on Australian Property Forum, the premier real estate site for property bears, bulls, investors, and speculators. Members may also discuss matters related to finance, modern monetary theory (MMT), debt deflation, cryptocurrencies like Bitcoin Ethereum and Ripple, property investing, landlords, tenants, debt consolidation, reverse home equity loans, the housing shortage, negative gearing, capital gains tax, land tax and macro prudential regulation.

Forum Rules: The main forum may be used to discuss property, politics, economics and finance, precious metals, crypto currency, debt management, generational divides, climate change, sustainability, alternative energy, environmental topics, human rights or social justice issues, and other topics on a case by case basis.
