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.
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.
Siberia defrosting would certainly be interesting. It has massive amount of methane under the ice.
The northwest passage is already open most summers so yes it will definitely open up - this is a benefit.
But you are bringing up very minor points of benefit.
Now, if the world was to warm very slowly and open up these parts then some of your arguments would hold more weight, but it is moving too fast for most species to keep up with. The optimum temperature has only a minor impact compared to the rate of change and the issues associated with that (mass extinctions - etc).
As for property values - well it depends on how long you are going to live. But I beleive you are late 30's. So yes, you will likely see values drop due to this in your lifetime. 1 - seaside properties (if sea level rise is prediction firm up on the high-side then these will be on borrowed time - future rent affects present value) 2 - floods (see above) 3 - money diverted from current economy to decarbonising the economy (costs associated with changes)
Did you even glance at the Stern report?
You aren't listening to what I am saying about RATE OF CHANGE. I summise you do not know what it means or the implications. This is climate science/economics 101. Learn it.
Nope it doesn't. This is not news to climate scientists, it is inherently understood.
It is only news to those who don't quite understand it. If ignorance was funny, the joke would be on you.
You see, the media and politicians have to dumb it down for people to understand and also make it relevant to people who can't understand future consequences of current actions. Therefore they twist the story enough to make you think it is causing problems now - this is the only thing they think people understand (and might be right for most). Then ask questions and write a story they themselves constructed and tell people they have disproved something.
IF it was deliberate it would be an age old marketing strategy. (but they aren't that clever).
I will also point out that there is no proof that the measured temperature change isn't causing the effects now. The story just points out there is no confidence that is is. I trust you don't understand this either.
I'm not really sure what you're trying to convince me of?
By what degree do you believe the climate will change if we...
A - Spend as much money as possible trying to prevent it? B - Do nothing to prevent it?
You have made up you mind and frame questions that show your limited understanding. You are rehashing old ground - I showed earlier that there is evidence that man contributes more than 50%, therefore we can eliminate this entirely. You choose to ignore it, instead thinking your opinion is of equal weight. This is your ego fucking with you ;)
I can lead an elephant to water but I can't make it drink.
There is no point to further "debate. "
All you possibly need is easily available to you online.
Well, there are folks working on it. A couple of years ago I saw an intriguing TED presentation on Geoengineering from a fellow in the field. I think this is the one here:
IIRC he seems a little over optimistic, but still worth a look.
Apart from the stuff he talks about, there has been a raft of ideas and research on increasing the albedo of the oceans, promoting algea blooms to lock up carbon, taking limestone from South Australia and dumping it into the sea (reducing the PH of the sea and allowing it to absorb more CO2), and a bunch of other stuff.
Much falls into the "what could possibly go wrong" category, but yes there is likely to be some available tools if things get too bad.
Not that we should rely on this...
Yes, I touched on this earlier. There is money to be spent here and ties in well with the "constructionist" viewpoint of many here.
I ask, how much effort does it take to not release a gas compared to how much energy it would take to clean it up or mitigate it's effects?

there are enough benefits beside stopping global warming from spend all that money to create non-fossil fuel world
we should not even discuss whether there is global warming or whether it is man-made, we should be discussing the most efficient way of replacing bad, ugly and non-sustainable fossil fuel economy

Looks like global mean sea levels have fallen recently...
They seem to be making some excuses that the drop is related to El Nino transitioning to La Nina, but I don't see that large a drop happening with prior El Nino / La Nina changeovers, and even if that is the cause, then we could apply the same logic to say that prior cyclical rises in sea level were partly caused by the opposite transition from La Nina to El Nino. Bottom line here is that there are far too many complex human and natural interactions impacting on climate change, and nobody knows what proportion of change is caused by each factor.

Sheeshh!
What I understand is that you have no evidence but a plethora of empty rhetoric to support your views.
DRAMATIC forecasts of global warming resulting from a doubling of atmospheric carbon dioxide have been exaggerated, according to a peer-reviewed study by a team of international researchers. In the study, published today in the leading journal Science, the researchers found that while rising levels of CO2 would cause climate change, the most severe predictions - some of which were adopted by the UN's peak climate body in its seminal 2007 report - had been significantly overstated.
The authors used a novel approach based on modelling the effects of reduced CO2 levels on climate, which they compared with proxy-records of conditions during the last glaciation, to infer the effects of doubling CO2 levels.
They concluded that current worst-case scenarios for global warming were exaggerated.
"Now these very large changes (predicted for the coming decades) can be ruled out, and we have some room to breathe and time to figure out solutions to the problem," the study's lead author, Andreas Schmittner, an associate professor at Oregon State University, said.
Scientists have struggled for many years to understand how to quantify "climate sensitivity" - how Earth will respond to projected increases in atmospheric carbon dioxide.
In 2007, the UN's peak climate body, the Intergovernmental Panel on Climate Change, warned that a doubling of CO2 from pre-industrial levels would warm the Earth's surface by an average of 2C to 4.5C, although some studies have claimed the impact could be 10C or higher.
Professor Schmittner said it had been very difficult to rule out these extreme "high-sensitivity" scenarios, which were very important for understanding risks associated with climate change.
The study found high-sensitivity models led to a "runaway effect" under which the Earth would have been covered in ice during the last glacial maximum, about 20,000 years ago, when CO2 levels were much lower.
"Clearly that didn't happen, and that's why we are pretty confident that these high climate sensitivities can be ruled out," he said.
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.
