A team including scientists, Indigenous people and conservationists point to the ecosystem connecting Yellowstone and the Yukon as an example of a region where humans and nature are flourishing together.
The Earth is already operating beyond its capacity to sustainably support the global population, according to new research highlighting growing strain on food systems, climate stability, and human well-being. Despite this, researchers say that slowing population growth and increasing global awareness could still help reduce long-term risks.
Researchers identify sharp rise to about 0.35C every decade, after excluding natural fluctuations such as El Niño
Data from World Inequality Report also showed top 10% of income-earners earn more than the other 90%
Exclusive: ‘Devastating consequences’ now inevitable but emissions cuts still vital, says António Guterres in sole interview before Cop30
The unspoken truth about humanity's frightening future.
The world has been too optimistic about the risk to humanity and planet – but devastation can still be avoided, says Timothy Lenton
Mark Lynas has spent decades pushing for action on climate emissions but now says nuclear war is even greater threat Climate breakdown is usually held up as the biggest, most urgent threat humans pose to the future of the planet today. But what if there was another, greater, human-made threat that could snuff out not only human civilisation, but practically the entire biosphere, in the blink of an eye?
What if the rules of the game have already sealed our fate? This is a brutal mathematical reality: an unstoppable, self-reinforcing chain reaction in the Earth’s climate system is now underway.
https://www.ucs.org/resources/1992-world-scientists-warning-humanity - Some 1,700 of the world's leading scientists, including the majority of Nobel laureates in the sciences, issued this appeal in November 1992. The World Scientists' Warning to Humanity was written and spearheaded by the late Henry Kendall, former chair of UCS's board of directors.
Human pressures have pushed the Earth system deep into the Anthropocene, threatening its stability, resilience and functioning. The Planetary Boundaries (PB) framework emerged against these threats, setting safe levels to the biophysical systems and processes that, with high likelihood, ensure life-supporting Holocene-like conditions. In this Review, we synthesize PB advancements, detailing its emergence and mainstreaming across scientific disciplines and society. The nine PBs capture the key functions regulating the Earth system. The safe operating space has been transgressed for six of these. PB science is essential to prevent further Earth system risks and has sparked new research on the precision of safe boundaries. Human development within planetary boundaries defines sustainable development, informing advances in social sciences. Each PB translates to a finite budget that the world must operate within, requiring strengthened global governance. The PB framework has been adopted by businesses and informed
Record emissions, temperatures and population mean more scientists are looking into possibility of societal collapse, report says
Scientists now fear that there is little more than five years left to prevent irreversible climate damage and stark changes to the Earth’s weather patterns from global carbon emissions, Minister for Climate Eamon Ryan has warned.
If currently implemented policies are continued with no increase in ambition, there is a 90% chance that the Earth will warm between 2.3°C and 4.5°C, with a best estimate of 3.5°C.
As space travel and lunar exploration becomes a near-future reality, we should consider the impact of human activities on the lunar environment.
Extreme weather is ‘smacking us in the face’ with worse to come, but a ‘tiny window’ of hope remains, say leading climate scientists
First complete ‘scientific health check’ shows most global systems beyond stable range in which modern civilisation emerged
Population ecologist William Rees, with the University of British Columbia's School of Community and Regional Planning, is reminding denizens of Earth that the planet can only support so many people. In his paper published in the journal World, he points out that many models have been developed over the years that show that only a certain number of animals (such as rats) can live in a given environment—they all show that at some point, a population correction occurs.
Antarctica’s sea ice levels are plummeting as extreme weather events happen faster than scientists predicted
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
