Black, African and Caribbean people are exposed to higher illegal nitrogen dioxide levels than the percentage of the population they account for

Black communities in London are disproportionately more likely to breathe illegal levels of air pollution than white and Asian ones, new research seen exclusively by the Guardian shows.

The study for the mayor of London shows black, African and Caribbean people account for 15.3% of all Londoners exposed to nitrogen dioxide (NO2) levels that breach EU limits, but they account for just 13.3% of the city’s population.

The new book by Mitch Hescox and Paul Douglas is a marriage of science and faith

Most of you are aware of a growing movement amongst persons of faith to bring more action on dealing with climate change. The argument is powerful for the faithful – the Earth is God’s gift to humanity. We should care for it accordingly.

From within this movement, there are huge voices, widely respected by both the scientific and faith communities. Perhaps the best known is Dr. Katherine Hayhoe, a top climate scientist who is also an evangelist Christian. There are other persons and organizations who work similarly to connect these two world viewpoints in a powerful yet common-sense way.

Ben Damh, Wester Ross Each stag is ready to fight to the death for his chance to mate – and he only has only a short window to take his opportunity

Ben Damh means “hill of the stag” in Gaelic. You can see why. In the season of the rut the hill is alive with the sight, sound and smell of red deer. Even before we reach the ridge we can hear roaring, like the sound of a distant lawnmower.

Each stag is ready to fight to the death for his chance to mate – and he only has only a short window to take his opportunity. On such poor ground as this, the hinds are in oestrus for just four short weeks around the beginning of October. They gather on the high greens to graze while the feeding is good, and the males soon follow.
