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.
Europe is no exception when it comes to the consequences of climate change. It is the fastest warming continent, with temperatures rising at around twice the global average rate.
Microplastics and nanoplastics (MNPs) are emerging as a potential risk factor for cardiovascular disease in preclinical studies. Direct evidence that this risk extends to humans is lacking.
Take part in the new scientific discussion about looming abrupt changes in the Earth system. This new webinar series invites scientists interested in tipping elements and the broader public to attend.
As we mark 100 days until the COP28 UN climate summit, the urgency of addressing the climate crisis has never been more palpable. Global failures to mitigate emissions and adapt to the impacts continue to wreak havoc on the planet, and we’re seeing this in a range of ways. Unprecedented extreme weather events have occurred with frightening regularity in 2023. In March, over 500 people lost their lives when Cyclone Freddy struck Malawi. Last month, flooding in the Philippines caused by Typhoons Doksuri and Khanun displaced more than 300,000 people, and the recent wildfires that ravaged Hawaii – in part exacerbated by climate change – continue to make for distressing headlines. This list is likely to become even longer by the end of the year, when COP28 gets underway in the United Arab Emirates (UAE).
The method used to conduct an attribution study consists of eight steps, described here. The first step is the selection of an extreme event to study. After selecting an extreme weather event to study, the first step is to define the event, which provides a framework for the study. Researchers determine the geographical boundaries of the most impacted area, the best index to quantify the meteorological extreme (eg. maximum temperature, average rainfall, etc), and the duration of the event.
It’s not that our models can’t simulate small-scale weather – they’re basically the same models we use for weather forecasting – it’s just very computationally expensive to have them zoom in and run in “weather mode” to get a highly detailed simulation.
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.
In his Cop27 speech this week, our will-he-go, won’t-he-go prime minister said that stopping the planet dangerously overheating was still within our grasp, leaving many wondering just what planet he was on. According to Rishi Sunak, last year’s Cop26 climate conference in Glasgow was all about keeping alive the possibility of preventing the global average temperature rise since the Industrial Revolution from climbing above 1.5C. That is “alive”, as in connected to a drip, in a coma and suffering cardiac arrest every few hours.
The amount of heat accumulating in the ocean is accelerating and penetrating ever deeper, with widespread effects on extreme weather events and marine life, according to a new scientific review.
Protesters from Just Stop Oil may be breaking the law and yet still be morally right in the face of future disaster
Prudent risk management requires consideration of bad-to-worst-case scenarios. Yet, for climate change, such potential futures are poorly understood. Could anthropogenic climate change result in worldwide societal collapse or even eventual human extinction? At present, this is a dangerously underexplored topic. Yet there are ample reasons to suspect that climate change could result in a global catastrophe. Analyzing the mechanisms for these extreme consequences could help galvanize action, improve resilience, and inform policy, including emergency responses. We outline current knowledge about the likelihood of extreme climate change, discuss why understanding bad-to-worst cases is vital, articulate reasons for concern about catastrophic outcomes, define key terms, and put forward a research agenda. The proposed agenda covers four main questions: 1) What is the potential for climate change to drive mass extinction events? 2) What are the mechanisms that could result in human mass mortality and morbidity? 3) Wh
Chief meteorologist says extreme temperatures ‘entirely consistent’ with human-induced climate crisis
‘This event is completely unprecedented and upended our expectations about the Antarctic climate system,’ one expert said
The Ukrainian crisis has revived an old debate: how to effectively sanction a state like Russia? Let’s say it straight away: it is time to imagine a new type of sanction focused on the oligarchs who have prospered thanks to the regime in question. This will require the establishment of an international financial register, which will not be to the liking of western fortunes, whose interests are much more closely linked to those of the Russian and Chinese oligarchs than is sometimes claimed. However, it is at this price that western countries will succeed in winning the political and moral battle against the autocracies and in demonstrating to the world that the resounding speeches on democracy and justice are not simply empty words.
The Australian Bureau of Meteorology has declared a La Niña weather event is under way, with modelling predicting it “will persist until the late southern hemisphere summer or early autumn 2022”.
Some of the worst financiers of the worts polluters helped write the script - and more, they will implement the decisions after the summit in Glasgow.
Five times in the last 500m years, more than three-fourths of marine animal species perished in mass extinctions. Each of these events is associated with a major disruption of Earth’s carbon cycle. How such catastrophes occur remains mysterious. But recent research increasingly points to the possibility that the Earth system – that is, life and the environment – may experience a cascade of disruptions when stressed beyond a tipping point.
Australian scientists have challenged the latest UN-backed global warming report, saying it underestimated the likelihood major weather events driven by processes in the Pacific will become more extreme as the planet heats.
Global weather is constantly in motion. The Southern Hemisphere is currently in Winter, and strong weather patterns will start a warming event in its Stratosphere. These events are rare, but powerful, having historically been strong enough to affect the entire globe.
Greenland's enormous ice sheet has been struck by a "massive melting event," with enough ice vanishing in a single day last week to cover the whole of Florida in two inches (5 centimeters) of water, Danish researchers have found.
Every metric ton of carbon dioxide humans emit comes at a cost—not only in terms of the financial toll of the damage wrought by floods, heat waves and droughts but also the price in human lives. Substantially curtailing emissions today could prevent tens of millions of premature deaths over the course of the 21st century, according to a new study that calculated this “mortality cost of carbon.”
A fierce cold snap brought rare snow, icy rain, and strong winds to parts of southern Brazil on July 29 and 30, 2021. The event comes after several waves of destructive frost since mid-June.
Michael Moore presents Planet of the Humans, a documentary that dares to say what no one else will — that we are losing the battle to stop climate change on planet earth because we are following leaders who have taken us down the wrong road — selling out the green movement to wealthy interests and corporate America. This film is the wake-up call to the reality we are afraid to face: that in the midst of a human-caused extinction event, the environmental movement’s answer is to push for techno-fixes and band-aids. It's too little, too late.
Study citing ‘perilous state’ of industrial civilisation ranks temperate islands top for resilience. New Zealand, Iceland, the UK, Tasmania and Ireland are the places best suited to survive a global collapse of society, according to a study.
Whenever an extreme weather or climate-related event occurs, the media and decision-makers ask the question to what extent it is influenced by climate change. For a few years now the scientific community has been able to answer that question for relatively simple extremes: hot and cold extremes, extreme precipitation and drought. This emerging field of climate science is called Extreme Event Attribution ...
A new report, published on 14 March, 2021 in the Royal Swedish Academy of Sciences’ journal Ambio, points out that humanity is hurtling towards destruction unless we have the collective wisdom to change course quickly.
While the climate crisis has dominated the airwaves for a while now, the biodiversity crisis is at least as serious. Actually, these are multiple, interconnected crises, stemming from age old systemic failings. In 2019, scientific body IPBES brought to the fore the urgent need for “transformative change” to prevent biodiversity collapse, which would be disastrous for people and planet. As one example, the global coronavirus pandemic has tragically highlighted the risks of ecosystem loss for global public health. In a bid to find an answer to this crisis, the United Nations Convention on Biological Diversity (CBD) is discussing a Global Biodiversity Framework (GBF) - effectively how to ‘save’ nature.
