Time series of climate-related responses to anthropogenic drivers, 1990-2020. Out of the 31 tracked planetary vital signs, 18 were at new all-time record lows or highs in 2020. Data obtained before and after the publication of Ripple and colleagues (2020) are shown in gray and red respectively. For variables with relatively high variability, local regression trend lines are shown in black. The variables were measured at various frequencies (e.g., annual, monthly, weekly). The labels on the x-axis correspond to midpoints of years. Sources and additional details about each variable are provided in the supplemental material. Graphic: Ripple, et al., 2021 / BioScience

World scientists’ warning of a climate emergency 2021 – Humans face untold suffering from “the consequences of unrelenting business as usual”

28 July 2021 (BioScience) – In 2019, Ripple and colleagues (2020) warned of untold suffering and declared a climate emergency together with more than 11,000 scientist signatories from 153 countries. They presented graphs of planetary vital signs indicating very troubling trends, along with little progress by humanity to address climate change. On the basis of […]

Graph showing Earth Overshoot Day, 1970-2021. Each year, Earth Overshoot Day marks the date when humanity has used all the biological resources that Earth regenerates during the entire year. Humanity currently uses 74% more than what the planet’s ecosystems can regenerate—or “1.7 Earths.” From Earth Overshoot Day until the end of the year, humanity operates on ecological deficit spending. This spending is currently some of the largest since the world entered into ecological overshoot in the early 1970s, according to the National Footprint & Biocapacity Accounts (NFA) based on UN datasets.

Earth Overshoot Day creeps back to July 29 in 2021 – “With almost half a year remaining, we will already have used up our quota of the Earth’s biological resources for 2021 by July 29th”

GLASGOW, UK, 4 June 2021 (Global Footprint Network) – Earth Overshoot Day 2021 lands on July 29, Councillor Susan Aitken, the Leader of Glasgow City Council, announced today on behalf of Global Footprint Network and the Scottish Environment Protection Agency (SEPA). “With almost half a year remaining, we will already have used up our quota […]

“War in the woods”: activists blockade Vancouver Island in bid to save ancient trees – “If we want our planet to be sustainable, we have to protect these ecosystems”

By Jesse Winter 9 April 2021 (The Guardian) – Hundreds of activists are digging in at logging road blockades across a swath of southern Vancouver Island, vowing to stay as long as it takes to pressure the provincial government to immediately halt cutting of what they say is the last 3% of giant old growth […]

Sea level rise is killing trees along the Atlantic coast, creating “ghost forests” that are visible from space

By Emily Ury 6 April 2021 (The Conversation) – Trekking out to my research sites near North Carolina’s Alligator River National Wildlife Refuge, I slog through knee-deep water on a section of trail that is completely submerged. Permanent flooding has become commonplace on this low-lying peninsula, nestled behind North Carolina’s Outer Banks. The trees growing in […]

Illegal gold rush in the Amazon raises risk to indigenous people – “They are coming in like starved beasts, looking for the wealth of our land”

By Luana Souza 24 March 2021 (Bloomberg News) – Illegal gold and diamond mining is proliferating in Brazil’s Amazon rain forest and threatening South America’s largest group of native people who still live in relative isolation, the Yanomami. Criminal mining groups are encroaching on the indigenous territory that straddles Brazil and Venezuela, polluting rivers, bringing diseases […]

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 […]

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’ […]

The global COVID-19 lockdowns caused fossil carbon dioxide emissions to decline by an estimated 2.4 billion tonnes in 2020 - a record drop according to researchers at the University of East Anglia, University of Exeter and the Global Carbon Project. It means that in 2020 fossil CO2 emissions are predicted to be approximately 34 GtCO2, seven per cent lower than in 2019. Emissions from transport account for the largest share of the global decrease. Those from surface transport, such as car journeys, fell by approximately half at the peak of the COVID lockdowns. Total CO2 emissions from human activities - from fossil CO2 and land-use change - are set to be around 39 GtCO2 in 2020. Video: UEA

COVID lockdown causes record drop in carbon dioxide emissions for 2020

11 December 2020 (UEA) – The global COVID-19 lockdowns caused fossil carbon dioxide emissions to decline by an estimated 2.4 billion tonnes in 2020 – a record drop according to researchers at the University of East Anglia (UEA), University of Exeter, and the Global Carbon Project. The fall is considerably larger than previous significant decreases […]
