The net zero approach of the Paris agreement has become detached from reality as it increasingly relies on science fiction levels of speculative technology.

Huge patches of forest in Tasmania have rapidly turned brown over recent months, with many trees dying after a dry summer. As climate change causes hotter and drier weather, can we expect more tree deaths in the future?

In recent months we have seen lifechanging technological advances in the capabilities and use of artificial intelligence. At the same time, we are witnessing new, life-threatening risks as a result of AI – from the propagation of disinformation, to mass surveillance, to the prospect of lethal autono

Over the past 50 years, humans have extracted the Earth’s groundwater stocks at a steep rate, largely to fuel global agro-economic development. Given society’s growing reliance on groundwater, we explore ‘peak water limits’ to investigate whether, when and where humanity might reach peak groundwater extraction. Using an integrated global model of the coupled human–Earth system, we simulate groundwater withdrawals across 235 water basins under 900 future scenarios of global change over the twenty-first century. Here we find that global non-renewable groundwater withdrawals exhibit a distinct peak-and-decline signature, comparable to historical observations of other depletable resources (for example, minerals), in nearly all (98%) scenarios, peaking on average at 625 km3 yr−1 around mid-century, followed by a decline through 2100. The peak and decline occur in about one-third (82) of basins, including 21 that may have already peaked, exposing about half (44%) of the global population to groundwater stress. Most

Evidence shows a continuing increase in the frequency and severity of global heatwaves1,2, raising concerns about the future impacts of climate change and the associated socioeconomic costs3,4. Here we develop a disaster footprint analytical framework by integrating climate, epidemiological and hybrid input–output and computable general equilibrium global trade models to estimate the midcentury socioeconomic impacts of heat stress. We consider health costs related to heat exposure, the value of heat-induced labour productivity loss and indirect losses due to economic disruptions cascading through supply chains. Here we show that the global annual incremental gross domestic product loss increases exponentially from 0.03 ± 0.01 (SSP 245)–0.05 ± 0.03 (SSP 585) percentage points during 2030–2040 to 0.05 ± 0.01–0.15 ± 0.04 percentage points during 2050–2060. By 2060, the expected global economic losses reach a total of 0.6–4.6% with losses attributed to health loss (37–45%), labour productivity loss (18–37%) and i

Temperatures in Iran are hitting record highs, rivers and lakes are drying up, and prolonged droughts are becoming the norm, highlighting a water crisis that is turning much of the country’s territory to dust. The desertification of Iran is occurring at a staggering pace, with officials last month warning that more than 1 million hectares of the country’s territory -- roughly equivalent to the size of Qom Province or Lebanon -- is essentially becoming uninhabitable every year.

Ocean-driven melting of floating ice-shelves in the Amundsen Sea is currently the main process controlling Antarctica’s contribution to sea-level rise. Using a regional ocean model, we present a comprehensive suite of future projections of ice-shelf melting in the Amundsen Sea. We find that rapid ocean warming, at approximately triple the historical rate, is likely committed over the twenty-first century, with widespread increases in ice-shelf melting, including in regions crucial for ice-sheet stability. When internal climate variability is considered, there is no significant difference between mid-range emissions scenarios and the most ambitious targets of the Paris Agreement. These results suggest that mitigation of greenhouse gases now has limited power to prevent ocean warming that could lead to the collapse of the West Antarctic Ice Sheet. The authors use a regional ocean model to project ocean-driven ice-shelf melt in the Amundsen Sea. Already committed rapid ocean warming drives increased melt, regard

Almost every country in the world has signed up to the Paris Agreement’s goal of keeping warming well-below 2C and pursuing efforts to limit it to 1.5C.

Although interest in colonisation has grown throughout the West in recent years, it is mostly limited to historical colonialism. Little attention is paid to the ways in which we colonise the future. However, this is done with the same ruthlessness and short-sightedness with which regions around the world were invaded in earlier times. During the 50th edition of the Huizinga Lecture, David Van Reybrouck focuses on the way in which humanity is currently plundering and enslaving future generations. And further, the violence is not limited to human but affects all life on earth.

Increasing risks posed by climate change are causing rare extreme events that can kill more than 10 million people or lead to damages of $10 trillion-plus, posing threats of total societal collapse, a UN report finds.
INTERLAKEN, Switzerland, March 20, 2023 -- There are multiple, feasible and effective options to reduce greenhouse gas emissions and adapt to human-caused climate change, and they are available now, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report released today. ...

The climate crisis has begun to disrupt human societies by severely affecting the very foundations of human livelihood and social organisation. Climate impacts are not equally distributed across the world: on average, low- and middle-income countries suffer greater impacts than their richer counterparts. At the same time, the climate crisis is also marked by significant inequalities within countries. Recent research reveals a high concentration of global greenhouse gas emissions among a relatively small fraction of the population, living in emerging and rich countries. In addition, vulnerability to numerous climate impacts is strongly linked to income and wealth, not just between countries but also within them.
Canadian author and professor of climate justice cautiously hails loss and damage agreements at Cop27. " I think the most important thing is to just find other people. Trying to think through this by yourself is a recipe for feeling like a failure and getting dispirited very, very quickly. The benefit of being part of a broader movement is knowing that some people are doing some things, and other people are doing other things, and nobody has to do everything."
The deployment of low-tech requires taking into account the human factor and changing design practices.

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
