Climate-driven oxygen loss in the Black Sea thousands of years ago triggered the expansion of microorganisms capable of producing the potent neurotoxin methylmercury. That is shown in a new study published in Nature Water, led by Eric Capo at Umeå University, which suggests that similar processes could occur in today’s warming oceans.

Planting wheat earlier in the spring to avoid crop damage from ever-hotter summers may not keep harvests on pace with current levels.

New research at Washington State University challenges assumptions that earlier planting could offset the effects of a warming climate. Researchers used computer modeling to show that moving crop plantings earlier in the season brings about other plant growth issues that could hinder productivity.

The findings were published in Communications, Earth, and Environment.
