How sea water circulation underneath Antarctic ice shelves is a vital missing link in climate change projections.
Net zero energy buildings produce at least as much energy as they use. Designing whole net zero campuses and communities takes the energy and climate benefits to a higher level.
Extreme weather events prompt people to move, a trend that could accelerate in a warming climate. But the ability to migrate internally in the US depends largely on economic status.

The long-awaited paper sets a positive tone. But it's not clear if the government grasps the sheer scale or urgency of the emissions reduction task.
Reef fish vanish during marine heatwaves, but may bounce back quickly on reefs that have few other environmental stressors.
While most corals turn ghostly white when they bleach, some turn neon purple. Scientists were baffled – until now.
Microscopic ocean phytoplankton feed a "biological pump" that carries carbon from the surface to deep waters. Scientists have found that this process stores much more carbon than previously thought.
Global quarantine is not a long-term solution – we still have a lot of work ahead.
'Wet-bulb' temperature records show that deadly thresholds for heat and humidity are arriving faster than anticipated.
Changes to Australia's emissions reduction policies may do little more than channel taxpayer money to industry.
New research reveals which sectors of the global economy fuelled the emissions decline during COVID-19. We have a narrow window of time to make the change permanent.
The COVID-19 pandemic is interrupting scientific field work across North America, leaving blank spots in important data sets and making it harder to track ecological change.
It is easy for people in the industrialised world to blame population growth elsewhere for environmental damage. But increased consumption is just as important – if more confronting.
