If the anomaly does not stabilise by August, ‘the world will be in uncharted territory’, says climate expert

Over the past year, there has been a vigorous debate among scientists – and more broadly – about whether global warming is “accelerating”.

An international team of scientists has warned against relying on nature providing straightforward 'early warning' indicators of a climate disaster, as new mathematical modeling shows new fascinating aspects of the complexity of the dynamics of climate. It suggests that the climate system could be more unpredictable than previously thought.

The Amazon rainforest is facing a barrage of pressures that might tip it into large-scale ecosystem collapse as soon as 2050, according to new research Wednesday warning of dire consequences for the region and the world. The Amazon, which holds more than 10 percent of the world's biodiversity, helps stabilize the global climate by storing the equivalent of around two decades of emissions of planet-warming carbon dioxide.

New paper claims unless demand for resources is reduced, many other innovations are just a sticking plaster Record heat, record emissions, record fossil fuel consumption. One month out from Cop28, the world is further than ever from reaching its collective climate goals. At the root of all these problems, according to recent research, is the human “behavioural crisis”, a term coined by an interdisciplinary team of scientists.

The European Commission has received an open letter signed by 110 academics, businesses, civil society organisations and research institutions urging the EU to separate emissions reductions, land-based sequestration and permanent carbon removals in the EU’s post-2030 climate framework. This separation should be at the heart of both the setting and the implementation of the 2040 target and associated plans.

Humanity faces ‘devastating domino effects’ including mass displacement and financial ruin as planet warms

Referring to the Paris Agreement’s target of keeping Earth from warming no more than 1.5 degrees Celsius since the Industrial Revolution, the number has become a rallying cry for climate advocates and scientists, who say the goal is humanity’s best bet on avoiding the most catastrophic outcomes of climate change by the end of the century. Venturing even 0.5 degrees past that threshold could drastically increase the frequency and severity of extreme weather, biodiversity loss, famine and water scarcity, as well as make it more likely that tipping points accelerate warming further, climate scientists say.

the starkest warning yet that human activity is pushing Earth into a climate crisis that could threaten the lives of up to 6 billion people this century, stating candidly: “We are afraid of the uncharted territory that we have now entered.” Writing in the journal Biosciences, the coalition of 12 researchers, spanning North America, Europe and Asia, state in unusually stark language: “As scientists, we are increasingly being asked to tell the public the truth about the crises we face in simple and direct terms. The truth is that we are shocked by the ferocity of the extreme weather events in 2023.”

Catastrophic climate change and the collapse of human societies By Josep Peñuelas, Sandra Nogué National Science Review, Volume 10, Issue 6, June 2023 The scientific community has focused the agend…

Previously, anthropogenic ecological overshoot has been identified as a fundamental cause of the myriad symptoms we see around the globe today from biodiversity loss and ocean acidification to the disturbing rise in novel entities and climate change. In the present paper, we have examined this more deeply, and explore the behavioural drivers of overshoot, providing evidence that overshoot is itself a symptom of a deeper, more subversive modern crisis of human behaviour. We work to name and frame this crisis as ‘the Human Behavioural Crisis’ and propose the crisis be recognised globally as a critical intervention point for tackling ecological overshoot. We demonstrate how current interventions are largely physical, resource intensive, slow-moving and focused on addressing the symptoms of ecological overshoot (such as climate change) rather than the distal cause (maladaptive behaviours). We argue that even in the best-case scenarios, symptom-level interventions are unlikely to avoid catastrophe or achieve more
