May 3 (UPI) The world s smallest plants, single-cell organisms called diatoms, provide exceptional carbon capture services, according to researchers.
According to a new study, published Monday in the journal Frontiers in Plant Sciences, diatoms mostly use a single cellular pathway to capture and concentrate CO2.

Every year, diatoms floating near the surface of the ocean capture 10 to 20 billion metric tons of CO2 via photosynthesis. Until now, scientists weren t sure how the unicellular plants concentrated CO2 so efficiently.

Feb. 2 (UPI) Most models underestimate the rate of sea level rise, according to a new study.
Researchers at the Niels Bohr Institute and the University of Copenhagen have developed a new method for testing sea level rise models against the historical record.

Jan. 25 (UPI) A new survey of ice loss around the globe suggests the rate at which the planet s ice sheets and glaciers are melting is rapidly accelerating.
According the new analysis, detailed Monday in the journal Cryosphere, Earth lost roughly 28 trillion tons of ice between 1994 and 2017. In 1994, Earth experienced an annual loss of 0.3 trillion tons of ice. By 2017, annual losses increased to 1.3 trillion tons.
Five years after the Paris climate agreement, bold visions for slowing global warming have emerged from all over the world. Less clear is how countries will meet them.
