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.
First complete ‘scientific health check’ shows most global systems beyond stable range in which modern civilisation emerged
Extreme weather is ‘smacking us in the face’ with worse to come, but a ‘tiny window’ of hope remains, say leading climate scientists
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
Recent news articles about a breakthrough in nuclear fusion research heralded the potential for “limitless” energy. Whenever I read that word limitless I wince, because I’ve learned to view it as a subtle instruction to readers to “please stop thinking now.” After decades of false promises to delive
Earth For All is both an antidote to despair and a road map to a better future. Using powerful state-of-the-art computer modeling to explore policies likely to deliver the most good for the majority of people, a leading group of scientists and economists from around the world present five extraordinary turnarounds to achieve prosperity for all within planetary limits in a single generation.
Global heating could become "catastrophic" for humanity if temperature rises are worse than many predict or cause cascades of events we have yet to consider, or indeed both. The world needs to start preparing for the possibility of a "climate endgame."
Experts call for a new ‘Climate Endgame’ research agenda, and say far too little work has gone into understanding the mechanisms by which rising temperatures might pose a catastrophic risk to society and humanity.
The EPA ruling means it may now be mathematically impossible through available avenues for the US to achieve its greenhouse gas emissions goal
António Guterres compares climate inaction to tobacco firms dismissing links between smoking and cancer
In the face of environmental collapse, humanity may need to turn to artificial replacements for nature – how might we avoid the most dystopian of these futures? Researcher Lauren Holt makes the case for a broader form of "offsetting" to help balance technology with natural systems.
Humankind is revealed as simultaneously insignificant and utterly dominant in the grand scheme of life on Earth by a groundbreaking new assessment of all life on the planet. The world’s 7.6 billion people represent just 0.01% of all living things, according to the study. Yet since the dawn of civilisation, humanity has caused the loss of 83% of all wild mammals and half of plants, while livestock kept by humans abounds.
Humanity has triggered the sixth mass extinction episode since the beginning of the Phanerozoic. The complexity of this extinction crisis is centred on the intersection of two complex adaptive systems: human culture and ecosystem functioning, although the significance of this intersection is not properly appreciated. Human beings are part of biodiversity and elements in a global ecosystem.
Inflation is a disease that disproportionately afflicts the poor. Even before Vladimir Putin unleashed his brutal war on Ukraine, whose byproducts include soaring energy and food prices, inflation was already over 7.5% in the US and above 5% in Europe and the UK. Calls for its taming are, therefore, fully justified – and the interest rate rise in the US, with the same expected in the UK, comes as no surprise. That said, we know from history that the cure for inflation tends to devastate the poor even more. The new wrinkle we face today is that the supposed solutions threaten not only to deal another cruel blow to the disadvantaged but, ominously, to snuff out the desperately needed green transition.
Rapidly rising levels of atmospheric methane are "very bad news for humanity and the planet," warned one observer.
Last month, the United Nations Intergovernmental Panel on Climate Change issued its latest report, sounding a “code red for humanity.” The IPCC stressed the need for drastic emissions cuts immediately if we want to maintain a habitable planet and warned that we are running out of time to act to avoid climate catastrophe.
The climate crisis is accelerating at unprecedented pace, according to a new United Nations state-of-the-science report. It is "a code red for humanity," said UN Secretary-General António Guterres — and given that the report concludes the entirety of the warming is due to human greenhouse gas emissions, avoiding the worst of its consequences is up to us.
