28 million American children between the ages of 5 and 12 are lining up to get vaccinated against COVID-19, after health authorities there gave Pfizer's jab for kids emergency approval.

In Australia, the health minister Greg Hunt says there'll be a little more of a wait, although he is indicating the first jabs could be administered to children by January.

So what do we know about how COVID-19 affects children?

And can the delay in vaccinating them be justified?

Australia has undergone a revolution in how we talk about many crimes and disorders.

A week ago we were wondering what the UN climate summit in Glasgow, COP26, might deliver for humanity.

We'd been told many times that the world is not on track to limit warming to less than 2 degrees, and that Glasgow was our best - if not our last - chance to fix that.

At the halfway mark, Swedish activist Greta Thunberg says the talks have already failed.

So is she right?

Today on The Signal, while world leaders have mostly left, negotiations still have a week to run.

So what's the world agreed to so far? And is there still cause for hope in the final week?

A handful of Nationals have pitched nuclear power as a way to lower Australia's emissions.

It's not the first time the idea has come up in Australia — but there's been a ban in place since 1998, and lacklustre public support since nuclear disasters such as Chernobyl.

So is it a good idea now, either environmentally or financially? And would the public support it this time around?

There's a lot of pressure on the leaders of wealthy countries gathering in Glasgow at the moment to be more ambitious on cutting emissions.

When the focus turns to Australia, the prime minister Scott Morrison has a standard reply: Australia's record on cutting emissions shows that we always keep our promises.

What he doesn't talk about, is how.

Today on The Signal, Australia's true record on climate targets.

How much of it is actually smoke and mirrors?
