Stuck in a rut: Ocean acidification locks algal communities in a simplified state

Researchers have found that ocean acidification limits algal communities to a state of low diversity and complexity. Communities grown in waters rich in carbon dioxide (CO2) were dominated by turf algae, and had low biodiversity, ecological complexity and biomass. Communities grown under acidic conditions and then transferred to waters that weren’t CO2-enriched increased their biodiversity and complexity, showing that they can recover if CO2 emissions are significantly reduced.

2020: Hottest Year On Record

NASA data show that 2020 was the hottest year on record.  The image below shows that high temperature in 2020 hit Siberia and the Arctic Ocean.  In above images, the temperature anomaly is compared to 1951-1980, NASA’s default baseline. When…

Changing resilience of oceans to climate change

(University of Exeter) Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests.

2020 tied for warmest year on record

2020 was Earth’s hottest year in the 140-year record, effectively tying 2016, the previous record-holder.

50 Countries Just Joined New Coalition to Protect 30% of the Planet’s Land and Oceans By Decade’s End

A band of more than 50 countries, chaired by France, the UK, and Costa Rica, have committed to an ambitious push to conserve and protect 30% of the world’s land and oceans by 2030. The agreement was made by the fledgling High Ambition Coalition for People and Nature (HAC) at the One Planet Summit for […]

Megalodon shark’s enormous babies ate their siblings in the womb

Megalodons – the extinct giant sharks that lived in most of Earth’s oceans about 3 million years ago – gave birth to babies that were larger than adult humans, scientists say.

New classification marks paradigm shift in how conservationists tackle climate change

(Wildlife Conservation Society) A new study co-authored by researchers from the Wildlife Conservation Society’s (WCS) Global Conservation Program and the University of British Columbia (UBC) Faculty of Forestry introduces a classification called Resistance-Resilience-Transformation (RRT) that enables the assessment of whether and to what extent a management shift toward transformative action is occurring in conservation.
