Jocalyn Clark: The surprising links between child marriage, climate change, and health

16 Jun, 15 | by BMJ

Jocalyn_Clark1It seems obvious that child marriage—marriage before 18 years of age—would be bad for girls’ health. It risks injury and death due to early pregnancy and abuse, and usually means girls stop going to school.

But the link to climate change is less conspicuous. A new Human Rights Watch report, focused on Bangladesh, which has one of the highest rates of child marriage in the world (a full 30% of females in this country are married before 15), sheds light on the role of climate change. Having never thought of adolescent health this way, I find the tripartite fascinating. more…

The BMJ Today: More on climate change

3 Oct, 14 | by BMJ

BirteEarlier this year, The BMJ’s editor in chief, Fiona Godlee, was one of 50 senior UK medical professionals to sign a letter in the Times newspaper about the health benefits of ending investment in fossil fuels, and diverting funds instead to alternative energy and more active forms of transport.

On 1 October 2014, The BMJ published an editorial, calling for the World Health Organization to declare a public health emergency. The BMJ has campaigned about climate change for years, and the reactions from our readers have been interesting—indeed, as Godlee writes, “When The BMJ started publishing articles on climate change, some readers told us to stick to our knitting.” more…

Daniel Maughan: What has climate change got to do with mental health?

15 Sep, 14 | by BMJ

This blog is part of a series on sustainable healthcare, which looks at health, sustainability, and the interplay between the two. The blog is coordinated by the Centre for Sustainable Healthcare and shares ideas from experts across the healthcare field.

The World Health Organization and the Lancet Commission have both stated that climate change is the largest threat to human health in the 21st Century. Does this threat extend to mental health? Weather systems are likely to become more unstable as global temperatures rise, but could unstable weather have an effect on the development of mental disorders? more…

Alistair Wardrope: Healthcare organisations and fossil fuel divestment

27 Jun, 14 | by BMJ

alistair_wardropeMuch has been said about the outcomes of the BMA’s Annual Representatives’ Meeting (ARM) this week. Of the debates held and motions passed, however, perhaps only Tim Crocker-Buqué’s tobacco motion has as strong a claim to world first status as motion 370. Buried in the rather dry sounding section on “Finances of the Association,” this motion called for strong action from the medical profession to tackle the health risks posed by climate change, including a commitment to “transfer their investments from energy companies, whose primary business relies upon fossil fuels, to those providing renewable energy sources.”

On Wednesday morning, the motion passed—albeit with the above clause passing “as a reference,” meaning that it is a direction to Council rather than policy, but the spirit and intent of the motion is kept. With it, the BMA became the first health sector organisation (to my knowledge) to publicly express its intent to divest from the fossil fuel industry. That the move comes from the BMA, one of the oldest and most respected medical professionals’ organisations in the world, demonstrates the power of the divestment movement. more…

Isobel Braithwaite: Taking bold steps to curb climate change

24 Jun, 14 | by BMJ

isobel_braithwaite_3At the end of May, US President Barack Obama unveiled new power plant standards, which are designed to cut pollution and curb greenhouse gas emissions. He should be applauded for this bold step in the right direction, and even more so for recognising and presenting it to the public as a public health policy, which will improve the health of all citizens—particularly children. Climate change is also a health problem. Speaking of the need for stronger standards, the head of the US Environmental Protection Agency (EPA), Gina McCarthy, has called climate change “the biggest public health challenge we face.”

Although carbon emissions are still considered primarily a matter for environmental policy, health considerations have been front and centre in this debate, and more so than with any previous set of energy policies. This reflects both the clear synergy between public health and climate mitigation, which is represented by measures to clean up our air, as well as the personal resonance of problems like smog and asthma for many citizens. more…

David McCoy: The science of climate denialism

26 Mar, 14 | by BMJ

david_mccoyIn a previous posting, I argued that it is important for everyone to have some understanding of climate science—which is why Medact produced a summary and discussion of the latest UN report about the physical science of climate change. I also questioned the scientific understanding of Owen Paterson, minister for environment, food, and rural affairs, following his ill judged comments on the UN report. But why is there is so much scepticism and denial about the evidence of anthropogenic global warming? more…

David McCoy: Why doctors need to take climate change seriously

4 Mar, 14 | by BMJ

david_mccoyOwen Paterson is the minister for environment, food, and rural affairs and therefore leads on government policy with regards to global warming. But his reaction to the latest report on the physical science of climate change by the Inter Governmental Panel on Climate Change (IPCC) raises questions about his fitness to play this vital role. If his attitude towards the care of the planet were transposed to a GP caring for a patient, would I advise the patient to find another GP?

The reason for bringing this up is because Medact has produced and released a summary and discussion of the IPCC report. We did this because the IPCC’s own summary of their 2000+ page report was hard to read. So we produced an alternative that we hope is more accessible—but without “dumbing down” the complexity of climate science. more…

David Pencheon: Climate change—knowing so much and doing so little

22 Jan, 14 | by BMJ

David PencheonAlthough I like to think I am a rational person who can consider most issues objectively, I know this is rubbish. I am biased, prejudiced, and a prisoner of my experience, although perhaps acknowledging this is better than denying it. Not easy, as the ability to deny is probably our most powerful coping mechanism, and extremely useful for people like doctors who spend much of their working lives dealing with constant uncertainty, suffering, and stress. There is only so much reality with which the human frame can cope, and many people do appear to be very skilled (maybe too skilled) at detachment, denialism, and clever ways of dealing with more than their fair share of pain, suffering, and death. Perhaps this explains why we sometimes seem so poor at understanding the effect of our behaviour and actions (or lack of them) on others. more…

Deon Louw: The doctor, the environmentalist, and the gospel of sustainable healthcare

15 Jul, 13 | by BMJ

deon_louwLet’s be honest. Lester Brown sounds like the name of a musician from the Deep South. In fact, Brown is an acclaimed scientist and I had the pleasure of attending one of his lectures. He has 25 honorary degrees and has published more than 50 books on how human systems (e.g. food systems) react to environmental and climate change.

Bearing these credentials in mind, I was surprised that Brown presented his audience with seemingly familiar ideas. He used the construct of supply and demand to explore global food scarcity. On the demand side he listed the pressures on grain supplies as: more…

Rachel Stancliffe and Mahmood Bhutta: Should doctors lead on sustainability?

1 Jul, 13 | by BMJ



Welcome to a new series of blogs on sustainable healthcare that will look at health, sustainability and the interplay between the two. The blog will share ideas from experts across the healthcare field, some of whom are speaking at a major European conference looking at Pathways to Sustainable Healthcare in September 2013.  More about the conference can be seen at

The GMC’s Good Medical Practice states that: “Good doctors make the care of their patients their first concern.” This is of course a laudable principle, and good doctors strive to ensure that patients are seen in a timely manner, that they are treated by appropriately trained staff, and that systems of clinical governance are in place to enable improvement. Yet we all know that we work within constraints, with these most commonly relating to financial or logistical constraints on service provision. However the evidence now makes it clear that those constraints should also include consideration of the wider impact of healthcare provision on the global need to care for the environment and to protect labour rights.   more…
