Lightning bolts break apart nitrogen and oxygen molecules in the atmosphere and create reactive chemicals that affect greenhouse gases.

It all started about four years ago, when SUVs and pickup trucks drove uninvited onto their lands, remembers Olimpia Palmar, a member of the Indigenous Wayúu peoples, who have historically occupied the La Guajira desert in northern Colombia and Venezuela.

A massive collaborative research project covered in the journal Nature this week offers projections to the year 2100 of future sea-level rise from all sources of land ice, offering the most complete projections created to date.

A team of Swiss and international climate scientists has shown that the risk of glacial lake outburst floods in the Himalayan region and the Tibetan plateau could triple in the coming decades.

The bulging, equator-belted midsection of Earth currently teems with a greater diversity of life than anywhere else — a biodiversity that generally wanes when moving from the tropics to the mid-latitudes and the mid-latitudes to the poles.

For millennia, humans in the high latitudes have been enthralled by auroras—the northern and southern lights. 

The air in the United States and Western Europe is much cleaner than even a decade ago. 

A study by the UPV/EHU’s CBET research group and the University of Bordeaux has shown that graphene oxide nanomaterials, alone and combined with polycyclic aromatic hydrocarbons, pose a potential source of toxicity to fish, but at concentrations that are above the currently expected environmental levels.

University of Exeter scientists used RFID – similar technology to contactless card payments – to monitor when bumblebees of different sizes left and returned to their nest.

In 2005, greenhouse gas (GHG) emissions from residential energy use hit an all-time high in the United States. Each year since, emissions have dropped at an average annual rate of 2 percent.
