A mother writes about joining an anti-fracking protest because of the threat to her children's lives from future global heating.

If you are a young person today, there is considerable danger you will be killed by global heating — not soon, of course, but when it reaches the point where millions are starving, and fighting over food, globalized supply chains could break down, which would make a lot of technology and industry stop working world-wide.

We can't predict what will happen, as there are too many imponderables. Maybe some lucky surprise will avert the disaster, but do you want to bet your life on that? If we are to avoid it, we have to curb the greenhouse gas emission now.

South Sudan is being torn apart by tribalism.

The West must not ignore the repeated messages that its wars stir up hatred.

There are two ways to consider terrorist attacks such as those in New York in 2001 and in London in 2005: as crimes or as war.

To consider them as crimes means responding by hunting and prosecuting the perpetrators — not by launching wars. If we view the issue in terms of crime, the attack on Rigby was a crime too and prosecuting its perpetrators was legitimate. However, invading Iraq was not legitimate and we have a duty to prosecute those responsible.

On the other hand, if we consider those terrorist attacks as war and say they justify war in response, the enemy can say the same. Viewed as war, the killing of Rigby was an attack by a guerrilla force on a military target. The US has committed plenty of war crimes, and so have the Taliban and its supporters, but attacking Rigby wasn't one.

We can't have it both ways.
