Mathematics predicts a sixth mass extinction

Scientists have analyzed significant changes in the carbon cycle over the last 540 million years, including the five mass extinction events. They have identified 'thresholds of catastrophe...

Wave Glider surfs across stormy Drake Passage in Antarctica

A hardy ocean drone made a first-ever attempt to surf across Antarctica's stormy Drake Passage gathering data about ocean mixing.

Fly away home? Ice age may have clipped bird migration

The onset of the last ice age may have forced some bird species to abandon their northerly migrations for thousands of years, says new research led by an ornithologist. The study challenges a long-...

Animal acoustic activity decline shows forest fire pollution wreaks havoc on wildlife

Forest fires in Southeast Asia during the El Niño droughts of 2015 caused considerable disruption to the biodiversity of the region due to the smoke-induced 'haze' they created, accordin...

Atmospheric effects of Arctic snowmelt

Researchers are exploring the changing chemistry of the Arctic's atmosphere to help answer the question of what happens as snow and ice begin to melt.

End-of-summer Arctic sea ice extent is eighth lowest on record

Arctic sea ice appeared to have reached its yearly lowest extent on Sept. 13, scientists have reported. Analysis of satellite data showed that at 1.79 million square miles (4.64 million square kilo...

Changes in non-extreme precipitation may have not-so-subtle consequences

Extreme floods and droughts receive a lot of attention. But what happens when precipitation -- or lack thereof -- occurs in a more measured way?

A cereal crop survives heat and drought

Scientists have published the genome sequence of Pearl millet, a drought resistant crop plant most important in arid regions in Africa and Asia. This plant is important to small and medium farmers ...

Urgent emission reductions needed to achieve 1.5°C warming limit

Significant emission reductions are required if we are to achieve one of the key goals of the Paris Agreement, and limit the increase in global average temperatures to 1.5°C; a new partnership war...

Changes in Earth's crust caused oxygen to fill the atmosphere

New research has uncovered a direct link between changes in the earth's crust three billion years ago and the introduction of free oxygen to the atmosphere. Without these changes, oxygen could...
