Both African elephant species are now endangered, one critically – “At this point, there can be no doubt that poaching and habitat loss have devastated populations of elephants all across Africa”

By Rachel Nuwer 25 March 2021 (National Geographic) – Elephants have long been thought of as either African or Asian. But there are actually two species of African elephant: The savanna elephant is larger, has curving tusks, and roams the open plains of sub-Saharan Africa. The smaller, darker forest elephant, with straight tusks, lives in the […]

Western Monarch butterfly abundance at 149 overwintering sites in California, 2017-2021. These critically low numbers follow two years with fewer than 30,000 butterflies—the previous record lows, indicating that the western monarch butterfly migration is nearing collapse. Sites were visited during both the Thanksgiving and New Year’s Counts during the 2020–2021 count season. Graphic: Xerces Society

Western Monarch butterfly population closer to extinction – No Endangered Species Act protection in sight – “In only a few decades, a migration of millions has been reduced to less than two thousand butterflies”

PORTLAND, Oregon, 19 January 2021 – The Xerces Society today announced that only 1,914 monarch butterflies were recorded overwintering on the California coast this year. This critically low number follows two years with fewer than 30,000 butterflies—the previous record lows—indicating that the western monarch butterfly migration is nearing collapse. The final results from the 24th annual Western […]

Forest degradation in the Monarch Butterfly Biosphere Reserve core area, 2002-2020. The presence of the Monarch butterfly in the Mexican hibernation forests decreased by 26 percent last December, occupying 2.10 hectares (ha) compared to the 2.83 hectares reported during the same month in 2019. Meanwhile, the core forest area in the Monarch Butterfly Biosphere Reserve (MBBR) where the lepidopteran establishes the main hibernation colonies recorded, between March 2019 and March 2020, 20.26 ha of degradation, four times more than in 2018-2019 when 5 ha were degraded.

Eastern Monarch butterfly population declined by 26 percent in 2020 – Degradation of temperate forests in the Monarch Butterfly Biosphere Reserve was four times higher than in 2019

By Wendy Caldwell 25 February 2021 MEXICO CITY (Monarch Joint Venture) – The presence of the Monarch butterfly in the Mexican hibernation forests decreased by 26 percent last December, occupying 2.10 hectares (ha) compared to the 2.83 ha reported during the same month in 2019. Meanwhile, the core forest area in the Monarch Butterfly Biosphere […]

Trump administration opens millions more acres of Alaska to drilling – “A last-minute and irresponsible effort to open an enormous amount of land in a sensitive area”

By Dino Grandoni 5 January 2021 (The Washington Post) – The Trump administration, in its final days, decided to open millions more acres of land in the Alaskan Arctic to oil and gas drilling. The decision from the Bureau of Land Management on Monday, finalized just two weeks before President Trump is set to leave office, will […]

Watching Earth burn – “The war has started. We’re losing.”

By Michael Benson 28 December 2020 (The New York Times) – I have a pastime, one that used to give me considerable pleasure, but lately it has morphed into a source of anxiety, even horror: earth-watching. Let me explain. The earth from space is an incomparably lovely sight. I mean the whole planet, pole to […]

Projected geographical shift of the human temperature niche. (Top) Geographical position of the human temperature niche projected on the current situation (A) and the RCP8.5 projected 2070 climate (B). Those maps represent relative human distributions (summed to unity) for the imaginary situation that humans would be distributed over temperatures following the stylized double Gaussian model fitted to the modern data (the blue dashed curve in Fig. 2A). (C) Difference between the maps, visualizing potential source (orange) and sink (green) areas for the coming decades if humans were to be relocated in a way that would maintain this historically stable distribution with respect to temperature. The dashed line in A and B indicates the 5% percentile of the probability distribution. Graphic: Xu, et al., 2020 / PNAS

Broken societies put people and planet on a collision course, says UNDP – “No country in the world has yet achieved very high human development without putting immense strain on the planet”

NEW YORK, 15 December 2020 (HDRO) – The COVID-19 pandemic is the latest crisis facing the world, but unless humans release their grip on nature, it won’t be the last, according to a new report [pdf] by the United Nations Development Programme (UNDP), which includes a new experimental index on human progress that takes into account countries’ […]

Biomass and anthropogenic mass estimates since the beginning of the twentieth century on a dry-mass basis. The green line shows the total weight of thebiomass (dashed green lines, ±1 s.d.). Anthropogenic mass weight is plotted as an area chart, where the heights of the coloured areas represent the mass of the corresponding category accumulated until that year. The anthropogenic mass presented here is grouped into six major categories. The year 2020±6 marks the time at which biomass is exceeded by anthropogenic mass. Anthropogenic mass data since 1900 were obtained from ref. 22, at a single-year resolution. The current biomass value is based on ref. 11, which for plants relies on the estimate of ref. 10, which updates earlier, mostly higher estimates. The uncertainty of the year of intersection was derived using a Monte Carlo simulation, with 10,000 repeats. Data were extrapolated for the years 2015–2025 (lighter area).

The mass of human-made materials now equals the planet’s biomass – “Anthropogenic” mass is doubling every twenty years

9 December 2020 (Weizmann Institute of Science) – Earth circa 2020: The mass of all human-produced materials – concrete, steel, asphalt, etc. – has grown to equal the mass of all life on the planet, its biomass. According to a new study at the Weizmann Institute of Science, we are right at this tipping point, […]

Climate change now top threat to natural World Heritage sites – Great Barrier Reef declines to “critical” status

GLAND, SWITZERLAND, 2 December 2020 (IUCN) – Climate change is now the biggest threat to natural World Heritage, according to a report [pdf] published today by IUCN (International Union for Conservation of Nature). A third (33%) of natural World Heritage sites are threatened by climate change, including the world’s largest coral reef, the Great Barrier […]

22 June 2020 (The Bee Informed Partnership) – The western honey bee, the species used across the country to support food production, to provide a natural sweetener, and to quite simply contribute to our leisure and free time, is among the most important of pollinators. To mark Pollinator Week, the Bee Informed Partnership (BIP) recently […]
