The only publication for climate action, covering the environment, biodiversity, net zero, renewable energy and regenerative approaches. It’s time for The New Climate.
Emerging infectious diseases, biodiversity loss, and anthropogenic environmental change are interconnected crises with massive social and ecological costs. In this Review, we discuss how pathogens and parasites are responding to global change, and the implications for pandemic prevention and biodiversity conservation. Ecological and evolutionary principles help to explain why both pandemics and wildlife die-offs are becoming more common; why land-use change and biodiversity loss are often followed by an increase in zoonotic and vector-borne diseases; and why some species, such as bats, host so many emerging pathogens. To prevent the next pandemic, scientists should focus on monitoring and limiting the spread of a handful of high-risk viruses, especially at key interfaces such as farms and live-animal markets. But to address the much broader set of infectious disease risks associated with the Anthropocene, decision-makers will need to develop comprehensive strategies that include pathogen surveillance across s

Natural ecosystems store large amounts of carbon globally, as organisms absorb carbon from the atmosphere to build large, long-lasting, or slow-decaying structures such as tree bark or root systems. An ecosystem’s carbon sequestration potential is tightly linked to its biological diversity. Yet when considering future projections, many carbon sequestration models fail to account for the role biodiversity plays in carbon storage. Here, we assess the consequences of plant biodiversity loss for carbon storage under multiple climate and land-use change scenarios. We link a macroecological model projecting changes in vascular plant richness under different scenarios with empirical data on relationships between biodiversity and biomass. We find that biodiversity declines from climate and land use change could lead to a global loss of between 7.44-103.14 PgC (global sustainability scenario) and 10.87-145.95 PgC (fossil-fueled development scenario). This indicates a self-reinforcing feedback loop, where higher levels

Although humans have long been predators with enduring nutritive and cultural relationships with their prey, seldom have conservation ecologists considered the divergent predatory behavior of contemporary, industrialized humans. Recognizing that the number, strength and diversity of predator-prey relationships can profoundly influence biodiversity, here we analyze humanity’s modern day predatory interactions with vertebrates and estimate their ecological consequences. Analysing IUCN ‘use and trade’ data for ~47,000 species, we show that fishers, hunters and other animal collectors prey on more than a third (~15,000 species) of Earth’s vertebrates. Assessed over equivalent ranges, humans exploit up to 300 times more species than comparable non-human predators. Exploitation for the pet trade, medicine, and other uses now affects almost as many species as those targeted for food consumption, and almost 40% of exploited species are threatened by human use. Trait space analyses show that birds and mammals threaten

Backed by the UN, an alliance of conservationists and policymakers is devising new ways to finance the preservation of biodiversity by placing economic values on ecosystems. Some analysts say such schemes have the potential to boost conservation, but others are skeptical.

The steady destruction of wildlife can suddenly tip over into total ecosystem collapse, scientists studying the greatest mass extinction in Earth’s history have found. Many scientists think the huge current losses of biodiversity are the start of a new mass extinction. But the new research shows total ecosystem collapse is “inevitable”, if the losses are not reversed, the scientists said.

Negotiators hope to put humanity on a path to harmonious coexistence with nature by 2050.

Small patches of land given over to wildlife-friendly planting can make a big difference to pollinator conservation, a new study suggests. Bee and other pollinator populations in Europe and North America are in decline due to a range of factors including habitat loss and insufficient flowers for food.

Industry groups representing some of the world’s largest companies are “opposed to almost all major biodiversity-relevant policies” and are lobbying to block them, according to a new report. Researchers found that 89% of engagement by leading industry associations in Europe and the US is designed to delay, dilute and block progress on tackling the biodiversity crisis, which scientists say is as serious as the climate emergency.
The summary for policymakers (SPM) and the chapters of the Methodological assessment regarding the diverse conceptualization of multiple values of nature and its benefits, including biodiversity and ecosystem functions and services (referred to as the “assessment of the diverse values and valuation of nature”), were approved and accepted respectively by the IPBES Plenary during its ninth session, held from 3 to 9 July 2022 in Bonn, Germany. The background of this assessment dates to 2013, when at its second session (IPBES 2) in Antalya, Turkey, the IPBES Plenary approved the initiation of scoping for a methodological assessment. During the third session of the IPBES plenary, in Bonn, Germany in 2015, the expert group established for scoping the methodological assessment and developing a preliminary guide, was requested to revise the scoping report for the methodological assessment based on comments received following an open review by Governments and stakeholders. At IPBES 4, in Kuala Lumpur, Malaysia in 2016

So it makes sense that, of all the patents found by the researchers, 47% belonged to Baden Aniline and Soda Factory (BASF), the largest chemical-producing company in the world. Collectively, Germany-based BASF owns 5,701 patents on sea life genes—more than any of the other 220 gene-patenting companies combined. Other major players include Dow Dupont, Bayer, Monsanto, Syngenta
A wildfire racing across a hillside has become emblematic of climate change. And for good reason: a quarter of the world’s natural landscapes now face longer fire seasons as a result of warming and shifts to rainfall, according to a recent landmark climate report.
Humans will cause so many mammal species to go extinct in the next 50 years that the planet's evolutionary diversity won't recover for 3 to 5 million years, a team of researchers has found.
To understand how long it will take to recover from this extinction event, a team of European scientists from Germany, Switzerland, the UK and The Netherlands decided to compare it with the previous mass extinction event, which occurred 66 million years ago when an asteroid hit our planet. This was a major event event that wiped off dinosaurs along with 75% of all species.

Our study assessed whether the opportunity to see many vertebrate animal species mattered to tourists visiting Costa Rica, and if so, how important it was compared with other features like hotels and beaches. in Costa Rica, our research shows that biodiversity needs to be paired with infrastructure like hotels and roads that enable access to nature.
A new study describes a period of rapid global climate change in an ice-capped world much like the present—but 304 million years ago. Within about 300,000 years, atmospheric carbon dioxide levels doubled, oceans became anoxic, and biodiversity dropped on land and at sea.

The Working Group II contribution to the IPCC Sixth Assessment Report assesses the impacts of climate change, looking at ecosystems, biodiversity, and human communities at global and regional levels. It also reviews vulnerabilities and the capacities and limits of the natural world and human societies to adapt to climate change.

In December 2020, 50 of the world’s leading biodiversity and climate experts, selected by a 12-person Scientific Steering Committee assembled by IPBES and IPCC, participated in a four-day virtual workshop to examine the synergies and trade-offs between biodiversity protection and climate change mitigation and adaptation.

Humanity has swung a wrecking ball through the biosphere. We have chopped down over half of the world’s rainforests and by the middle of this century there may not be much more than a quarter left. This has been accompanied by a massive loss in biodiversity, such that the biosphere may be entering one of the great mass extinction events in the history of life on Earth.
