Nitrogen makes up approximately 78% of the air we breathe. But scientists have never fully understood how it came to be present in the atmospheres around Earth and other planets.

Forestation is one of the main strategies recommended by the scientific community for climate change mitigation.

A new study shows that “hotspots” of nutrients surrounding phytoplankton — which are tiny marine algae producing approximately half of the oxygen we breathe every day — play an outsized role in the release of a gas involved in cloud formation and climate regulation.

At the Delaware Memorial Bridge, about 35 miles southwest of Philadelphia, the tidal waters of the Delaware River estuary push upstream with every incoming tide but are opposed by the river’s downstream flow. 

A new study shows that plant materials originating in Arctic sea ice are significantly incorporated into marine food webs that are used for subsistence in local communities of the greater Bering Strait region. 

Hurricanes moving slowly over an area can cause more damage than faster-moving storms, because the longer a storm lingers, the more time it has to pound an area with storm winds and drop huge volumes of rain, leading to flooding. 

In a study published in Nature Sustainability, an ecosystem scientist and an agricultural economist outline how to develop a more sustainable land management system through data collection and stakeholder buy-in.

Not long ago, the azure waters of the Caribbean contained healthy and pristine coral reef environments dominated by the reef-building corals that provide home to one-third of the biodiversity in the region.

The huge Antarctic iceberg has floated into warmer waters, but it is still mostly intact.

After ruling out pressure within the magma chamber, scientists investigate precipitation as a cause for 2018 eruption.
