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.

Climate change: what would 4°C of global warming feel like? – The Conversation UK

Another year, another climate record broken. Globally, 2020 tied with 2016 as the warmest year ever recorded. This was all the more remarkable given that cool conditions in the Pacific Ocean – known as La Niña – began to emerge…

Greenland melting likely increased by bacteria in sediment

Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island’s contribution to sea-level rise, according to scientists. That’s because the microbes cause sunlight-absorbing sediment to clump together and accumulate in the meltwater streams, according to new study. The findings can be incorporated in climate models, leading to more accurate predictions of melting, scientists say.

Scientists reduce uncertainty in forest carbon storage calculations

Investors who bet on tropical forest conservation and reforestation to solve global warming by storing carbon in wood face huge uncertainties because the science behind predicting carbon stocks is still shaky. Even the best Earth Systems Models fail to predict how carbon stored by tropical forests varies from place to place.

Extreme fire weather

(University of California – Santa Barbara) When the Thomas Fire raged through Ventura and Santa Barbara counties in December 2017, Danielle Touma, at the time an earth science researcher at Stanford, was stunned by its severity. Burning for more than a month and scorching 440 square miles, the fire was then considered the worst in California’s history.
