Most of the world's chalk streams are in southern and eastern England and are under particular strain.

Foreign companies should not be able to sue the government for taking action on climate change

An article in the Conversation with the catchy title “Hey Minister, leave that gas trigger alone” has urged the Labor government not to extend the Turnbull government’s gas trigger, which could be used to compel foreign-owned gas companies to keep gas reserves for use in Australia in some circumstances. It warns that actually using the trigger could inadvertently allow such companies to seek to sue the government under Australia’s existing international agreements.

Many Australians don’t know this but some of our trade agreements give foreign-owned companies special legal rights to sue the federal government if a change in law or policy reduces their profits, even if the change is in the public interest. The mechanism is known as an investor-state dispute settlement (ISDS).

Canadian oil and gas producers could potentially receive compensation for reducing the same emissions under federal and subnational climate policies that incorporate carbon capture, utilisation, and storage (CCUS), threatening the environmental integrity of these programmes and deflating credit prices, experts told Carbon Pulse.

Climate research finds modelling used cannot predict localised extreme weather, leading to poor estimations of risk

Trillions of dollars may be misallocated to deal with the wrong climate threats around the world because the models used by central banks and regulators aren’t fit for purpose, a leading Australian climate researcher says.

Prof Andy Pitman, director of the Australian Research Council’s Centre of Excellence for Climate Extremes, said regulators are relying on models that are good at forecasting how average climates will change as the planet warms, but are less likely to be of use for predicting how extreme weather will imperil individual localities such as cities, however.

The concerns, detailed in a recent report in the journal Environmental Research: Climate, were underscored by the Australian Prudential Regulation Authority’s release on Monday of its corporate plan 2022-23. Apra plans to “continue to ensure regulated institutions are well-prepared for the risks and opportunities presented by climate change”.
