Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

Sir: Whilst Charles Arthur is right to report ongoing damage to the ozone layer ("Ozone layer over western Europe falls by two-thirds", 3 December), it really is mischievous to say that the gradual thinning of this layer has increased the occurrence of skin cancer due to over- exposure to ultraviolet rays. There is simply no evidence for this.

Monitoring of ultraviolet radiation reaching the Earth's surface by agencies such as the National Radiological Protection Board in this and other European countries is showing no long-term upward trend.

The incidence of skin cancer is certainly rising and we can debate why this might be. What it is not due to, however, is changes in ambient ultraviolet consequent to ozone depletion.
