We are the last generation that can prevent irreparable damage to our planet, let's clean up, catch up and smarten up.

Recent mobile phone-based technologies can provide new insights into the effects of large-scale migrations as they happen.

How we can create a more ambitious, more radical (and maybe even more optimistic) view of the low-carbon future.

Around 700,000 lives are lost worldwide due to antimicrobial-resistant infections every year. Without viable antibiotic treatment options we are likely to return to a relative dark age of medicine – a time when common infections or injuries could kill, and common surgeries and immunosuppressive therapies may become unfeasible.

With an ever-increasing energy demand, the world is in need of a powerful and inexhaustible energy source. Nuclear fusion, presenting the additional advantage of being a clean source of energy, is the ideal candidate. Inertial confinement could solve the remaining challenge of producing high enough temperatures and pressures to hold the fusion material together.

The possibility of the UK exiting the European Union, or Brexit, could have a significant impact on national energy policy and infrastructure. The EU referendum could define whether the UK will meet its Paris COP21 targets, and what energy resources are utilised.

The growth of pro-government political militias and unidentified armed groups has traditionally been associated with weak state capacity however, new research suggests this may be a method of institutional management and can be seen as evidence of a strong state rather than a fragile one.

Much debate surrounds the choice of indicator used to determine economic performance and stage of development for governments, businesses and citizens.

A promising technology that aims to reflect a small percentage of sunlight back into space called Solar Radiation Management (SRM) could complement mitigation and adaptation in the fight against climate change.

Is ‪climate‬ modelling for carbon pricing based on theoretical assumptions that are unlikely to hold in the real world? The benefits of carbon pricing are highly uncertain, and hence it is likely not the most effective way to tackle greenhouse gas emissions.

In 2003, one million people fled Beijing during a SARS outbreak. In 2009, tens of thousands fled Zimbabwe during an outbreak of cholera. Anna Brach and Khalid Koser discuss how health crises arising from climate change are a significant driver of mass migration.

Automatic enrolment to pro-social programmes is popular but unlikely to always be the optimal policy. New behavioural economics research suggests that whether a policy breeds guilt or resentment helps determine if it will be effective or not.

Climate change affects everyone. For Arctic communities, the unpredictable nature of the changes is having a profound impact on health and entire livelihoods. The Arctic people know they’ll need to adapt to a rapidly changing landscape, one in which dependency on the seasons can no longer be relied upon.

In order to tackle exposure to air pollution emissions in urban environments, policies should aim to keep people away from the most polluted areas rather than focusing exclusively on containing the root of the pollution itself.

What distinguishes many of today's problems from those faced by former generations? The interconnected nature of global issues like emerging bio-technologies and climate change raises the possibility of 'wildfire risks', where the actions of one can have a great impact on many.

The challenge of moving towards a low carbon future is one now embraced by the political leaders of the G7, but how that path will unfold is still a live political debate. Local energy co-operatives offer a viable and progressive path to sustainability.

Marine energy has the potential to play a key role in the UK's energy mix in the coming decades, benefited by both its geography and its historical expertise. It is now critical that the necessary steps are taken to enable the technology to progress to the commercially viable stage, and realise its full potential.

A rights-based approach to protecting victims of climate-induced displacement is needed; one which recognises entitlement to assistance and protection, and leverages opportunities for safe and dignified migration.

Catastrophe models are an emerging tool for governments, NGOs and international aid agencies to assess and prepare for the risks posed by natural disasters.

Nuclear proliferation in the Middle East is high on the regional and international agenda. Fear of a nuclear arms race in the region driven by tensions between Iran and Israel, and continued mistrust surrounding the Iranian nuclear programme, threaten preparations for the upcoming Helsinki conference.

Can humanitarian aid ever really be non-political? How far should NGOs go to avoid being drawn into the power-struggles inherent to warfare? And what happens when international organisations are denied access, and local communities become the only humanitarian actors?

The human mind is fascinated by the possibility of other life in the universe. From as early as the fifth century B.C, science fiction and science fact have been intricately linked driving forward innovation and imagination.

International collaboration in space exploration has provided a platform for immense technological innovation and research that has benefited a range of scientific disciplines.

The Japanese government and their domestic nuclear industry are facing a serious dilemma. While geologists caution about the risk of active seismic faults the electric power industry is pressing the need to restart nuclear power plants.

Until now only a fraction of 1% of energy has been provided by direct conversion of solar energy, but that is set to change: International Energy Agency projections anticipate that some 11% of electric power will be provided by solar technologies by 2050.

Access to clean water is a fundamental human need. We must find low-cost ways of analysing toxic contaminants in the field, and develop cheap and effective remediation methods.

The answer to nuclear waste disposal may lie in deep underground geological storage, yet this strategy faces strong ‘Not In My Back Yard’ opposition.

High rates of urbanisation and population growth has led to housing and infrastructural incapacity in Ghana, threatening the country's economic success story.
