Scientists have created the first ever large-scale map of microscopic algae as they bloomed across the surface of snow along the Antarctic Peninsula coast. Results indicate that this ‘green snow’ is likely to spread as global temperatures increase.

The team, involving researchers from the University of Cambridge and the British Antarctic Survey, combined satellite data with on-the-ground observations over two summers in Antarctica to detect and measure the green snow algae. Although each individual alga is microscopic in size, when they grow en masse they turn the snow bright green and can be seen from space. The study is published today in the journal Nature Communications.

Climate warming affects individual trees differently, driving evolutionary responses

Research involving the University of Liverpool has revealed how natural selection can shape the long-term response of trees to climate change. Many tree species reproduce using a strategy called masting, where they switch between years of high and low seed production. Concentrating seed production into occasional bumper...

Gold mining restricts Amazon rainforest recovery

29 June 2020

Gold mining significantly limits the regrowth of Amazon forests, greatly reducing their ability to accumulate carbon, according to a new study. The researchers warn that the impacts of mining on tropical forests are long-lasting and that active land management and restoration will be necessary to recover tropical forests on previously mined lands.

Long-term thermal sensitivity of Earth’s tropical forests

22 May 2020

Tropical forests are well-known as crucial global carbon sinks that act by removing carbon from the atmosphere and storing it in trees, thereby slowing climate change. There are fears that global heating can reduce this storage capacity if tree growth reduces or tree death increases, further accelerating climate change.
