Ancient marine algae provides clues of climate change impact on today’s microscopic ocean organisms

  • PDF

A study of ancient marine algae, led by the University of Southampton, has found that climate change affected their growth and skeleton structure, which has potential significance for today’s equivalent microscopic organisms that play an important role in the world’s oceans.

Coccolithophores, a type of marine algae, are prolific in the ocean today and have been for millions of years. These single-celled plankton produce calcite skeletons that are preserved in seafloor sediments after death. Although coccolithophores are microscopic, their abundance makes them key contributors to marine ecosystems and the global carbon cycle.

The ‘microbial garden’ taking the shine off glaciers

  • PDF

The first study of the ecological diversity of an entire glacier has found that microbes can drastically reduce the reflectivity of the surface and have a non-negligible impact on the amount of sunlight that is reflected back into space.

The research, led by the University of Leeds and published today [12 June] in the journal FEMS Microbiology Ecology, will help improve climate change models that have previously neglected the role of microbes in darkening the Earth’s surface.

Observing how life thrives at extreme cold temperatures also has important implications for the search for life on distant worlds, such as Jupiter's icy moon Europa.

Picture of sunrise over Bonn for Your Expert Witness storyJune saw two weeks of meeting in Bonn to pave the way for a final international agreement on climate change in Paris next year. Despite early disappointment at the small number of environment ministers attending – despite an undertaking given in Warsaw last year for ministers to attend – the communique issued on 15 June was upbeat.

It stated: “The positivity around the past two week’s meetings culminated at the close when governments asked that the elements of a draft treaty be made available by July in advance of the next meetings in Bonn in October.”

Renault has reduced its carbon footprint by 10% in three years

  • PDF

By making a public commitment to reduce its carbon footprint by 10% between 2010 and 2013, and by meeting that objective, the Renault group has achieved an automotive industry first.

The policy is part of the Group’s determination to reduce the greenhouse gases (and CO2 in particular) emitted by its products and activities and to play an active part in the fight against global warming potential worldwide.
