The Kenyan marine ecologist David Obura is chair of a panel of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the world’s leading natural scientists. For many decades, his speciality has been corals, but he has warned that the next generation may not see their glory because so many reefs are now “flickering out across the world”.

Major study finds world's most productive farming regions are especially vulnerable to rising temperatures, and face steep declines in agricultural output this century.

In the run-up to the November election, conventional analysis suggested that a Trump victory would mean an additional four billion tons of CO2 emissions to the atmosphere by 2030, a total surrender on the climate pledges the country had made under the Paris Agreement and the functional end of the global goals that agreement established among nearly all the world’s nations.

In 1919, at the height of a global crisis that resulted from the turmoil of the Russian Revolution, the devastation of the first world war, and the collapse of Europe’s great continental empires, Irish writer William Butler Yeats penned his famed warning to humanity, mourning the end of the old world: “Things fall apart; the centre cannot hold / Mere anarchy is loosed upon the world.”

Among the many things global warming will be melting this century—sea ice, land glaciers and tourist businesses in seaside towns across the world—is permafrost. Lying underneath 15% of the northern hemisphere, permafrost consists of accumulating dead biomass that remains frozen, never having had a chance to release all its carbon.

A recent paper suggested damaging climate tipping points could be closer than first thought.

the starkest warning yet that human activity is pushing Earth into a climate crisis that could threaten the lives of up to 6 billion people this century, stating candidly: “We are afraid of the uncharted territory that we have now entered.” Writing in the journal Biosciences, the coalition of 12 researchers, spanning North America, Europe and Asia, state in unusually stark language: “As scientists, we are increasingly being asked to tell the public the truth about the crises we face in simple and direct terms. The truth is that we are shocked by the ferocity of the extreme weather events in 2023.”

The celebrated science broadcaster and environmental activist says we have to stop elevating the economy and politics over the state of our world

The WFPHA proposes to lead a discussion about global aid and Global Health Initiatives (GHIs), beginning in these Federation Pages. In this issue (JPHP 31.1), we have invited authors from the Department of Public Health from the Institute of Tropical Medicine Antwerp, Belgium, and from the Federal Ministry of Health, Addis Ababa, Ethiopia to discuss the ‘New dichotomy in health systems’ strengthening and the role of global health initiatives’. Next, the WFPHA will take a very active part in the upcoming Geneva Forum, 19–21 April 2010, entitled Globalization, Crisis & Health Systems: Confronting Regional Perspectives (http://www.ghf10.org/). The problems of GHIs will be the topic of a special session. In it, the organisers will integrate views of researchers, such as the contributors here, along with those of GHIs professionals, and participants from recipient countries.

In recent years, governments of several low-income countries have taken decisive action by removing fully or partially user fees in the health sector. In this study, we review recent reforms in six sub-Saharan African countries: Burkina Faso, Burundi, Ghana, Liberia, Senegal and Uganda. The review d …

In the last few years, one of the solutions envisaged for improving access to healthcare – seen by some as a step toward universal access – is to remove part of the financial barrier to healthcare ...

Although interest in colonisation has grown throughout the West in recent years, it is mostly limited to historical colonialism. Little attention is paid to the ways in which we colonise the future. However, this is done with the same ruthlessness and short-sightedness with which regions around the world were invaded in earlier times. During the 50th edition of the Huizinga Lecture, David Van Reybrouck focuses on the way in which humanity is currently plundering and enslaving future generations. And further, the violence is not limited to human but affects all life on earth.

Industry funds ‘grassroots’ resistance to tougher rules while touting green credentials, study shows

Wildfires, floods and soaring temperatures have made climate change real to many Americans. Yet a sizeable number continue to dismiss the scientific consensus that human activity is to blame. “Victory,” according to the American Petroleum Institute’s memo, “will be achieved when average citizens ‘understand’ (recognize) uncertainties in climate science… Unless ‘climate change’ becomes a non-issue… there may be no moment when we can declare victory.”

Deforestation coupled with the rampant destruction of natural resources will soon have devastating effects on the future of society as we know it, according to two theoretical physicists who study complex systems and have concluded that greed has put us on a path to irreversible collapse within the next two to four decades.

In 1998, as nations around the world agreed to cut carbon emissions through the Kyoto Protocol, America’s fossil fuel companies plotted their response, including an aggressive strategy to inject doubt into the public debate.

Recent studies from around the world show insects are disappearing fast. If this continues, this will have profound consequences for mankind and for our planet, for insects provide a myriad of vital ‘ecosystem services’, such as pollination, pest control, decomposition and recycling. This lecture looks at the causes of this crisis, at possible solutions including more sustainable farming systems, and at what we can do individually to create insect-friendly habitats.

Nonviolent protests are twice as likely to succeed as armed conflicts – and those engaging a threshold of 3.5% of the population have never failed to bring about change.

Today’s oceans are a tumult of engine roar, artificial sonar and seismic blasts that make it impossible for marine creatures to hunt or communicate. We could make it stop, so why don’t we?

Joe Biden is under pressure to declare a national climate emergency as temperatures soar across the US and Europe. Facing political gridlock in Washington, the president could make such an announcement – which would unlock federal resources to address the crisis – as soon as this week, the Washington Post reported on Tuesday.
