“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.

Colombia’s long-standing internal conflict and the country’s contribution to climate change share one common root cause: land concentration. Policies to strengthen access to land and to ensure sustainable land use might therefore hold the key to promoting peacebuilding in Colombia, while simultaneously reducing emissions.
As disasters wreak havoc all over South Asia, health impacts have increasingly emerged as a major concern for communities and governments in the region. It underscores the need for concerted efforts towards building synergies between the Paris Agreement, the Sendai Framework for Disaster Risk Reduction and the 2030 Sustainable Development Agenda, particularly now, in the post-disaster reconstruction phase, to ensure “building back better” and future disaster prevention.
In the Inner Mongolian county of Horinger, Northwestern China, afforestation efforts have transformed a barren, dusty landscape into a pine forest. Planting trees has diminished the sandstorms, boosted biodiversity and improved the environment generally. As the climate emergency worsens, the potential for planted trees to draw carbon out of the atmosphere is being re-examined. What can the world learn from the Chinese experience with afforestation?
Two events in August 2019 underlined the complexity of paving the way to a climate-neutral world: the publishing of the new IPCC report and the Amazon fires. Both events demand that climate diplomats move beyond a narrowed focus on energy in decarbonisation debates.
