Arctic ice levels logged in the last two years have reached record lows, whilst per decade have – on average since 1979 to 2020 – dropped by nearly 13%, a new vast report on the ocean worldwide shows.

Sea ice covered more area this summer compared to recent years, but it was also much thinner.

Today's technology offers far better solutions, creating a network of animal trackers that can deliver accurate, GPS-enabled otter locations more frequently.

The new insights come during a time when Arctic sea ice appears to have hit its annual minimum extent after waning during the warmer months in 2021.

Ecosystems provide multiple services for humans. However, these services depend on basic ecosystem functions which are shaped by natural conditions like climate and species composition, and human interventions.

Plastic pollution clogs river systems for considerably longer than previously thought, new research from the University of Leicester shows.

Reactive nitrogen emissions contribute to greenhouse gases, as well as air and water pollution.

Coral reefs are among the most biologically diverse, complex and productive ecosystems on the planet. Most of coral reef biodiversity consists of tiny organisms living deep within the three-dimensional reef matrix.

Coral reefs all over the world, already threatened by rising temperatures brought about by climate change, also face serious challenges from the possibility of fish species extinctions. 

Few craters are as large, or as old, as this impact structure in southeastern Ontario, Canada.
