Suddenly, at the level of central banks, Australia is regarded as an investment risk.
On Wednesday Martin Floden, the deputy governor of Sweden's central bank, announced that because Australia and Canada were "not known for good climate work".
As a result the bank had sold its holdings of bonds issued by the Canadian province of Alberta and by the Australian states of Queensland and Western Australia.
Central banks normally make the news when they change their "cash rate" and households pay less (or more) on their mortgages.
But central banks such as Australia's Reserve Bank and the European Central Bank, the People's Bank of China and the US Federal Reserve have broader responsibilities.
As an example, the new managing director of the International Monetary Fund Kristalina Georgieva warned last month that the necessary transition away from fossil fuels would lead to significant amounts of "stranded assets".
Those assets will be coal mines and oil fields that become worthless, endangering the banks that have lent to develop them. More frequent floods, storms and fires will pose risks for insurance companies. Climate change will make these and other shocks more frequent and more severe.
In a speech in March the deputy governor of Australia's Reserve Bank Guy Debelle said we needed to stop thinking of extreme events as cyclical.
And he said the changes that will be imposed on us and the changes we will need might be abrupt.
Australia's central bank and others are going further then just responding to the impacts of climate change. They are doing their part to moderate it.
Over thirty central banks (including Australia's), and a number of financial supervisory agencies, have created a Network for Greening the Financial System.
Its purpose is to enhance the role of the financial system in mobilising finance to support the transitions that will be needed. The US Federal Reserve has not joined yet but is considering how to participate.
One of its credos is that central banks should lead by example in their own investments.
They hold and manage over A$17 trillion. That makes them enormously large investors and a huge influence on global markets.
As part of their traditional focus on the liquidity, safety and returns from assets, they are taking into account climate change in deciding how to invest.
The are increasingly putting their money into "green bonds", which are securities whose proceeds are used to finance projects that combat climate change or the depletion of biodiversity and natural resources.
Over A$300 billion worth of green bonds were issued in 2018, with the total stock now over A$1 trillion.
Central banks are investing, and setting standards
While large, that is still less than 1% of the stock of conventional securities. It means green bonds are less liquid and have higher buying and selling costs.
It also means smaller central banks lack the skills to deal with them.
These problems have been addressed by the Bank for International Settlements, a bank owned by 60 of the central banks.
In September it launched a green bond fund that will pool investments from 140 (mostly central bank) clients.
Its products will initially be denominated in US dollars but will later also be available in euros. It will be supported by an advisory committee of the world's top central bankers.
It is alert to the risk of "greenwashing" and will only buy bonds that comply with the International Capital Market Association's Green Bond Principles or the Climate Bond Initiative's Climate Bond Standard.
Launching the fund in Basel, Switzerland, the bank's head of banking Peter Zöllner said he was
It's an important role. Traditionally focused on keeping the financial system safe, our central banks are increasingly turning to using their stewardship of the financial system to keep us, and our environment, safe.
