The IPCC's stern warnings about the pressing danger of global heating are an understatement.

How to ramp up the sense of danger? For one thing, stop using the bland term "climate change" that was imposed by Dubya's global heating denialists and start talking about "global heating".

Meanwhile, efforts to direct politicians' attention towards the necessary action face censorship.

Under great pressure, Abbott agreed that the G20 meeting statement can include a token paragraph about global heating.

As long as he prevents any substantive action to reduce use of fossil fuels, he considers it a victory.
