United States Secretary of State John Kerry goes to Indonesia and delivers a powerful warning:

“Because of climate change, it’s no secret that today Indonesia is … one of the most vulnerable countries on earth. It’s not an exaggeration to say that the entire way of life that you live and love is at risk …

“Think about the proliferation of weapons of mass destruction. It doesn’t keep us safe if the United States secures its nuclear arsenal while other countries fail to prevent theirs from falling into the hands of terrorists. The bottom line is this: it is the same thing with climate change. In a sense, climate change can now be considered another weapon of mass destruction, perhaps even the world’s most fearsome weapon of mass destruction.

“Terrorism, epidemics, poverty, the proliferation of weapons of mass destruction: all challenges that know no borders. The reality is that climate change ranks right up there with every single one of them.”

Australia’s Prime Minister, Tony Abbott, goes bush — to regions devastated by worsening drought — and stands on bone-dry fields among dead cattle and broke farmers.

He is not asked about the impact of climate change.

And he doesn’t once address it.
