The Amazon Rainforest is approaching a tipping point beyond which it would become savannah – “When it will be observable, it would likely be too late to stop it”

By Eric Shank 14 March 2022 (Salon) – A vast expanse of unique biological diversity hangs in the balance as the “lungs of the world” approach a tipping point from which there is no recovery. The Amazon Rainforest is losing its ability to regenerate, reported a peer-reviewed study, Monday, in Nature Climate Change. For 10% of all known species on […]

Aerial view of an area in the Amazon deforested for the expansion of livestock, in Lábrea, Amazonas state. The Amazon is still covered in smoke and torn by criminal and unrestrained destruction, according to overflights produced by the Amazon in Flames Alliance, organized by Amazon Watch, Greenpeace Brazil and the Brazilian Climate Observatory. The expedition took place between September 13th and 17th 2021, in the cities of Porto Velho (Rondônia state) and Lábrea (southern Amazonas state).

Brazil detects record Amazon deforestation in January and February 2022 – Forest destruction rate in 2021 was highest in ten years

By David Biller 11 March 2022 RIO DE JANEIRO (AP) – Detected deforestation in the Brazilian Amazon reached a record high for the month of February following a similar record the prior month. Satellite alerts of deforestation in February corresponded to 199 square kilometers (77 square miles), the highest indicator for that month in seven […]

Two bird species that are extinct but not listed as such, for fear of committing the “Romeo Error”. Both species are still listed as Critically Endangered by IUCN because of the slim chance that one or more birds may still be alive. Such species are therefore not counted among extinct species, and vast sums of money are often spent in the vain hope that they will be found again.

Earth on trajectory to Sixth Mass Extinction say biologists – “Including invertebrates is key to confirming that we are indeed witnessing the onset of the Sixth Mass Extinction in Earth’s history”

By Marcie Grabowski 14 January 2022 (UH News) – Mass biodiversity extinction events caused by extreme natural phenomena have marked the history of life on Earth five times. Today, many experts warn that a Sixth Mass Extinction crisis is underway, this time entirely caused by human activities. A comprehensive assessment of evidence of this ongoing […]

(a) Linear sea surface temperature (SST) trend (°C yr-1) for August of each year from 1982 to 2021. The trend is only shown for values that are statistically significant at the 95 percent confidence interval; the region is shaded gray otherwise. White shading is the August 2021 mean sea ice extent, and the yellow line indicates the median ice edge for Aug 1982-2010, (b, c) Area-averaged SST anomalies (°C) for August of each year (1982-2021) relative to the 1982-2010 August mean for (b) Baffin Bay and (c) Chukchi Sea regions shown by blue boxes in (a). The dotted lines show the linear SST anomaly trends over the period shown and trends in °C yr-1 (with 95 percent confidence intervals) are shown on the plots. Mean August SST warming trends from 1982 to 2021 persist over much of the Arctic Ocean, with statistically significant (at the 95 percent confidence interval) linear warming trends of up to +0.1°C yr-1 (a). Overall, Baffin Bay SSTs are becoming warmer in August with a linear warming trend over 1982-2021 of 0.05 ± 0.01°C yr-1 (b). Similarly, Chukchi Sea August mean SSTs are warming, with a linear trend of 0.06 ± 0.03°C yr-1 (c). Mean August SSTs for the entire Arctic (the Arctic Ocean and marginal seas north of 67° N) exhibit a linear warming trend of 0.03 ± 0.01°C yr-1. Graphic: Timmermans and Labe / NOAA

Amazon deforestation soars to 15-year high – “This is not surprising. The result of pulling apart Brazil’s environmental policy is deforestation.”

By Manuela Andreoni 19 November 2021 RIO DE JANEIRO (The New York Times) – Brazil’s pledge this month to end illegal deforestation in eight years drew much praise from global leaders, but an official report this week cast doubt on that commitment after it showed that the rate of deforestation in the Amazon rainforest was at its […]

Satellite view of Lake Tuz in Turkey acquired on 23 October 2021. Lake Tuz is Turkey's second-largest lake and home to several bird species. During the summer of 2021, the lake completely dried up causing the death of thousands of flamingos and other bird species that inhabit the lake. Experts attribute the extreme drought in eastern Turkey to climate change. Photo: European Union / Copernicus Sentinel-2 imagery

Haunting satellite imagery shows Turkey’s second-largest lake has dried up

By Molly Taft 2 November 2021 (Gizmodo) – A new satellite image of Turkey’s Lake Tuz is gorgeous—and, if you know more about what it’s portraying, worrying. The stunning capture from the European Space Agency’s Sentinel-2 satellite shows Turkey’s second-largest lake has completely dried up this year, exposing a haunting expanse of salt. While Lake Tuz, one of the world’s largest saltwater lakes, […]

The American bumblebee has vanished from eight states – Bee population has plummeted by 89 percent over past 20 years – “Endangered species” listing could be imminent

By Elizabeth Gamillo 6 October 2021 (Smithsonian) – The American bumblebee (Bombus pensylvanicus)—once abundant and found lazily floating around in grasslands, open prairies, and some urban areas throughout the United States—now face a rapidly declining population. According to a proposed rule released by the U.S. Fish and Wildlife Service, the species’ population has dropped nearly 90 percent […]
