The most extensive survey of atmospheric chemical compositions of exoplanets to date has revealed trends that challenge current theories of planet formation and has implications for the search for water in the solar system and beyond.

Concentrations of methane, a greenhouse gas about 28 times more potent than carbon dioxide, have risen steadily in Earth’s atmosphere since 2007. 

In a two-year experiment in Ireland and Switzerland, researchers found a positive relationship between plant diversity and yield stability in intensely managed grassland, even under experimental drought conditions. 

Close friendships improve the survival chances of rhesus macaques, new research shows.

As the climate changes, myriad animal populations are being impacted. In particular, Arctic sea-ice is in decline, causing polar bears in the Barents Sea region to alter their feeding and hunting habits. 

What are those streaks over the horizon? New Starlink satellites reflecting sunlight.

The Global Groundwater Statement — A Call  to Action cites recent scientific breakthroughs that have highlighted the regional and international importance of the issue as well as global connections and threats to groundwater, which makes up 99 per cent of the Earth’s liquid freshwater.

Greenland is losing ice faster than in the 1990s and is tracking the Intergovernmental Panel on Climate Change’s high-end climate scenario.

Understanding what influences the amount of methane in the atmosphere has been identified by the American Geophysical Union to be one of the foremost challenges in the earth sciences in the coming decades because of methane’s hugely important role in meeting climate warming targets.

The identification of natural carbon sinks and understanding how they work is critical if humans are to mitigate global climate change.
