U.K. project examines the idea of a nuclear-powered passenger aircraft
As worries about the rising price of oil and climate change grow, so grows the interest in nuclear power — but not only for ground-based power generation; a U.K. government-funded project examines the idea of nuclear-powered passenger plane

Sun's growing brightness a threat to Earth
The Sun is slowly getting brighter and warmer; in seven billion years it will engulf Earth — but much sooner, in 1.1 billion years, the Sun will grow 11 percent brighter, raising average terrestrial temperatures to around 50 °C, causing oceans to evaporate; the solution: move Earth away from the Sun

The long view
Keeping the lights on during and after a disaster
The threat of an inevitable earthquake is the uncomfortable truth we all face in the Cascadia Subduction Zone, which stretches from Alaska to California. Because the last major earthquake in the area was in the 1700s, our infrastructure developed without an appreciation and understanding of earthquake resilience. That means the next major earthquake will likely devastate our buildings, roads, bridges, and utility providers, posing immediate risks for the health and safety of those who live in the region. And later, there will be long-term economic aftershocks.
Causal link established between climate, conflict, and migration
Researchers have established a causal link between climate, conflict, and migration for the first time, something which has been widely suggested in the media but for which scientific evidence is scarce. There are numerous examples in recent decades in which climatic conditions have been blamed for creating political unrest, civil war, and subsequently, waves of migration. One major example is the ongoing conflict in Syria, which began in 2011. Many coastal Mediterranean countries in Europe are also inundated with refugees arriving by sea fleeing conflict in Africa.
In one generation, climate of North American cities will shift hundreds of miles
In one generation, the climate experienced in many North American cities is projected to change to that of locations hundreds of miles away—or to a new climate unlike any found in North America today. New web application helps visualize climate changes in 540 North American cities.
Water security key to unlocking African prosperity
There is mounting evidence of the risks posed by water scarcity to business and economic growth. A 2012 projection by the International Food Policy Research Institute says 45 percent of total GDP — $63 trillion — will be at risk due to water stress by 2050. With coordinated action, better water provision in Africa will strengthen economic growth and unlock the path to prosperity for millions, according to SABMiller’s Chief Executive Alan Clark.
Freshwater vulnerability threatens developing nations' stability
Many nations and regions already facing uncertain political futures must contend with a growing threat to stabilization: freshwater vulnerability. An analysis of 119 low-income countries finds common challenges that could inform broad solutions.
1.5°C vs 2°C global warming: Half a degree makes a big difference
European researchers have found substantially different climate change impacts for a global warming of 1.5°C and 2°C by 2100, the two temperature limits included in the Paris climate agreement. The additional 0.5°C would mean a 10-cm-higher global sea-level rise by 2100, longer heat waves, and would result in virtually all tropical coral reefs being at risk.
