17 June 2019 (University of Southampton) – The first mission involving the autonomous submarine vehicle Autosub Long Range (better known as Boaty McBoatface) has for the first time shed light on a key process linking increasing Antarctic winds to rising sea temperatures. Data collected from the expedition, published today in the scientific journal PNAS, will […]
By Alison Auld 11 June 2019 (Dal News) – Populations of large fish and other marine species will decline steadily if little is done to stem the effects of climate change, according to a study led by Dalhousie University researchers that shows how greenhouse gas emissions could cause widespread global stock losses and habitat shifts. […]
By Rebecca Morelle 13 May 2019 (BBC News) — An American explorer has found plastic waste on the seafloor while breaking the record for the deepest ever dive. Victor Vescovo descended nearly 11km (seven miles) to the deepest place in the ocean – the Pacific Ocean’s Mariana Trench. He spent four hours exploring the bottom […]
By Dr. Jeff Masters 6 May 2019 (Weather Underground) – If humanity maintains its current business-as-usual emissions path for the next 100 years, the resulting 4°C (7°F) of warming may be enough to cause highly reflective stratocumulus clouds over the subtropical and tropical oceans to disintegrate, resulting in an additional 8°C (14°F) of warming, according […]
By Jennifer Chu 6 May 2019 (MIT News) – Virtually all marine life depends on the productivity of phytoplankton — microscopic organisms that work tirelessly at the ocean’s surface to absorb the carbon dioxide that gets dissolved into the upper ocean from the atmosphere. Through photosynthesis, these microbes break down carbon dioxide into oxygen, some […]
By Naveena Sadasivam 17 April 2019 (Grist) – For more than a decade, indigenous communities in Alaska have been fighting to prevent the mining of copper and gold at Pebble Mine in Bristol Bay, home to the world’s largest sockeye salmon fishery and a crucial source of sustenance. The proposed mine, blocked under the Obama […]
By Lindsay Fendt 15 April 2019 (The Guardian) – Every year, from November through March, leatherback sea turtles arrive to the secluded shores of the Río Escalante Chacocente wildlife reserve on Nicaragua’s Pacific coast to lay their eggs. Though leatherback nesting habits vary, Chacocente has been a reliable egg-laying site for as long as conservationists […]
4 April 2019 (James Cook University) – The damage caused to the Great Barrier Reef by global warming has compromised the capacity of its corals to recover, according to new research published today in Nature. “Dead corals don’t make babies,” said lead author Professor Terry Hughes, Director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University (JCU). […]
1 April 2019 (UZH) – An unprecedented marine heatwave had long-lasting negative impacts on both survival and birth rates on the iconic dolphin population in Shark Bay, Western Australia. Researchers at UZH have now documented that climate change may have more far-reaching consequences for the conservation of marine mammals than previously thought. Shark Bay in […]
28 March 2019 (WMO) – The physical signs and socio-economic impacts of climate change are accelerating as record greenhouse gas concentrations drive global temperatures toward increasingly dangerous levels, according to a new report from the World Meteorological Organization. The WMO Statement on the State of the Global Climate in 2018, its 25th anniversary edition, highlights […]
