A day to cheer, break open the champagne, a historic global climate deal with a goal to keep warming well below 2 degrees Celsius has been reached ("Countries strike grand deal to tackle climate change", smh.com.au,   December 13). Prime Minister Turnbull is to be congratulated, overturning the ban on the Clean Energy Finance Corporation investing in wind farms.
Now a ban on all new coal mines and fossil fuel subsidies is more than possible with the depressed state of coal and oil prices. 
Bring on the technology and clean energy revolution - positive change is afoot for a more balanced Australian economy and brighter future for all.

Your correspondent Tom Arup's challenge to Malcolm Turnbull is full of insinuation about how he might dodge his climate responsibilities and not deliver what Arup thinks he should ("Paris delivers but can Turnbull", smh.com.au,   December 13).
Well, welcome to politics. Arup's comment that Turnbull was "giving a carefully balanced speech with one eye on the politics back home" would have been true of every leader who spoke at the conference.
Turnbull has been Prime Minister for only three months. Sure he hasn't changed every arch-Conservative policy that was foisted on the electorate in 2013 through broken promises and a broken budget.
But he hasn't been elected by the Australian people in his own right and he still is saddled with Coalition policies that he probably doesn't agree with.
He has no option but to go forward carefully and politically, until he can make policy changes that are more intelligent and progressive on a whole range of issues.
I'll take bets on a double dissolution in the first half of 2016. Perhaps a little patience is in order for the media just now.

In Paris, our minister Julie Bishop urges all countries to take the necessary steps towards a low-carbon emissions future. Let us see if there is truth in the saying: "There is no zealot like a convert."

The number of delegates at Paris' climate change conference would be greater than the number of wind turbines operating globally. Plenty of hot air there to keep everybody warm during the vote.

That should take some of wind out of Abbott's sails ("Malcolm Turnbull has lifted Tony Abbott's wind power investment ban", smh.com.au   December 13).

Awake, Sir Tony (Quixote) Abbott, your lance is broken.

Huge cost of justice
The unseemly Independent Commission Against Corruption v Margaret Cunneen v David Levine saga throws the spotlight on the legal system in NSW ("Car crash and fake boobs make Margaret Cunneen's battle with ICAC great fodder for Sydney shock jocks",   December 11-12).
Here we have an example of the "legal class" fighting it out, on what most would call somewhat trivial matters, at vast expense to taxpayers. That the Australian Crime Commission is involved (more taxpayer funds) adds further to the feeling of insult to the public.
The legal community derives vast amounts from government-instituted inquiries, commissions and ongoing appointments.
Who is monitoring this largesse to ensure value for money and public benefit?
The royal commission into the building industry is estimated to eventually cost up to $80 million. The bulk of this will go into the pockets of barristers and solicitors, earning up to $5000 each day; a daily rate more than a monthly income for many Australians.
The recent spat between members of the Bar Association over the use of SC v QC and the email war of words gave the public an insight into the machinations of this privileged group. It was not a good look.
The cost of legal representation in NSW is often cited as a reason for not pursuing a rightful cause. Consumers are at the mercy of a unionised cartel that sets its own rules and rates. Are they worth it?
