“Tackling climate change in fact represents one of the greatest opportunities to benefit human health for generations to come”, according to the co-chair of the Commission on Health and Climate, Professor Anthony Costello, director University College London Institute for Global Health. The Commission, a group of scientists convened by The Lancet journal, has published its second report on 22 June 2015.
The study brings together data on climate and population trends and quantifies the future global health impacts of climate change. It looks at both direct impacts of extreme weather like heat, floods and storms, and adverse indirect effects of food insecurity, poor air quality or even displacement. For instance, three times more people will be exposed to drought by the end of the century and four times more to extreme rainfall. In many areas, this implies no less than reversing development gains. Urgent action on mitigating climate change and preparing for its health-related challenges is needed: actual carbon emission rates have been even higher than in the worst-case scenario of the previous Lancet study (2009) on health and climate.
Major health co-benefits of climate action should encourage policy-makers to act more decisively. Fortunately, there is increasing momentum. For example, the intergovernmental Climate and Clean Air Coalition to Reduce Short Lived Climate Pollutants (CCAC), initiated in 2012, emphasises that mitigating methane, black carbon, and HFCs can help avoid two million premature deaths every year. In fact, air pollution was proclaimed one of “the leading avoidable causes of disease and death globally” by the World Health Assembly in a resolution of 26 May 2015, as every year 8 million deaths can be attributed to polluted air exposure indoor and outdoor.

Pakistan’s unprecedented climate shocks make it clear: regional cooperation for managing shared waters is desperately needed. To halt the increasing impacts on agriculture and livelihoods that cripple the country’s economy, diplomacy is of paramount importance. In our interview, Moeen Khan explains how territorial and ethnic tensions with India hinder much-needed transboundary solutions – and how the international community can help.
Environmental defenders in Brazil are at risk — last year, 57 were assassinated and the numbers are increasing. The UN has launched a new initiative to address the escalating violence. This article shows the challenges faced by an activist from the Amazon region who fights for justice, and it notes how the Brazilian government can save lives while preventing unregulated exploitation in the region.
Changes are occurring that could make climate action a driver of the domestic agenda for economic and social progress and for international cooperation. With the help of market forces and technological advances, the tide is moving toward climate action. Paul Joffe argues that a key to success is a strategy that draws public support and makes climate policy a force in a larger industrial renaissance.
The world can achieve slower climate warming, preventing temperatures from rising by more than 1.5˚C, a global scientific panel says. But time is short.
