Blog edited by Sam Carana, with news on climate change and warming in the Arctic due to snow and ice loss and methane releases from the seafloor.
Elizabeth Kolbert on a record-breaking rise in global sea-surface temperatures, which suggests that scientists may not understand how fast the climate is changing.
Climate records tumbled "like dominoes" in 2023, with temperatures far above any recorded level.
Capitalism's endless growth paradigm can't be squared with sustainability. But no one – from politicians to the protest movement – is willing to admit the truth
Bonn and Geneva, 6 September 2023 (ECMWF and WMO) - Earth just had its hottest three months on record, according to the European Union-funded Copernicus Climate Change Service (C3S) implemented by ECMWF. Global sea surface temperatures are at unprecedented highs for the third consecutive month and Antarctic sea ice extent remains at a record low for the time of year.
It’s the middle of winter in South America, but that hasn’t kept the heat away in Chile, Argentina and surrounding locations. Multiple spells of oddly hot weather have roasted the region in recent weeks. The latest spell early this week has become the most intense, pushing the mercury above 100 degrees Fahrenheit, while setting an August record for Chile.
The baby boomer dream of tanning on the beach is fading as temperatures rise. We are going to have to reinvent July and August.
According to ERA5 data from the EU-funded Copernicus Climate Change Service (C3S), the first three weeks of July have been the warmest three-week period on record and the month is on track to be the hottest July and the hottest month on record. These temperatures have been related to heatwaves in large parts of North America, Asia and Europe, which along with wildfires in countries including Canada and Greece, have had major impacts on people’s health, the environment and economies.
Current climate policies will leave more than a fifth of humanity exposed to dangerously hot temperatures by 2100, new research suggests. The paper, published in the journal Nature Sustainability, is entitled "Quantifying the Human Cost of Global Warming."
The WFPHA proposes to lead a discussion about global aid and Global Health Initiatives (GHIs), beginning in these Federation Pages. In this issue (JPHP 31.1), we have invited authors from the Department of Public Health from the Institute of Tropical Medicine Antwerp, Belgium, and from the Federal Ministry of Health, Addis Ababa, Ethiopia to discuss the ‘New dichotomy in health systems’ strengthening and the role of global health initiatives’. Next, the WFPHA will take a very active part in the upcoming Geneva Forum, 19–21 April 2010, entitled Globalization, Crisis & Health Systems: Confronting Regional Perspectives (http://www.ghf10.org/). The problems of GHIs will be the topic of a special session. In it, the organisers will integrate views of researchers, such as the contributors here, along with those of GHIs professionals, and participants from recipient countries.
Microplastic pollution reduces energy production in a microscopic creature found in freshwater worldwide, new research shows. Paramecium bursaria contain algae that live inside their cells and provide energy by photosynthesis. The results of a NEW STUDY showed a 50% decline in net photosynthesis—a major impact on the algae's ability to produce energy and release oxygen
Over the past week, police have taken brutal steps to suppress ecological movements in Europe and the United States. In Germany, police evicted and destroyed the long-occupied village of Lützerath in a massive operation in order to expand an ecologically devastating open pit coal mine.
Wildfires, floods and soaring temperatures have made climate change real to many Americans. Yet a sizeable number continue to dismiss the scientific consensus that human activity is to blame. “Victory,” according to the American Petroleum Institute’s memo, “will be achieved when average citizens ‘understand’ (recognize) uncertainties in climate science… Unless ‘climate change’ becomes a non-issue… there may be no moment when we can declare victory.”
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.
A study of healthy volunteers found that the combination of heat and humidity gets dangerous faster than many people realize
It’s hot and getting hotter. The first six months of the year are about 0.2°C cooler than the first six months of 2016 and 2020 (Fig. 1), but that’s only because the current La Nina continues to cool the tropics. Global temperature is rising despite the La Nina. Earth is out of energy balance (more solar energy absorbed than heat radiated to space) by an astounding amount – more than any time with reliable data – so, within a few years, we will be setting new global temperature records.
An alarming trend shows average temperatures have increased by at least 2F since 1970, with even higher spikes in the west and south-west
What else is new? Hotspots are getting hotter. The major hotspot in April stretched from Iraq to India and Pakistan, and toward the northeast through Russia (Fig. 1). Temperature exceeded 45°C (113°F) in late April in at least nine Indian cities,[1] on its way to 50°C (122°F) in Pakistan in May,[2] where a laborer says “It’s like fire burning all around” and a meteorologist describing growing heatwaves since 2015 says “The intensity is increasing, and the duration is increasing, and the frequency is increasing.” Halfway around the world, Canada and north-central United States were cooler than their long-term average, but people in British Columbia and northwest United States remember being under their own record-breaking hotspot last summer.
As Earth’s climate warms, incidences of extreme heat and humidity are rising, with significant consequences for human health. Climate scientists are tracking a key measure of heat stress that can warn us of harmful conditions.
Warmer winters are happening across the globe, and can be drivers of catastrophic weather events and profound changes
"Trajectoires du Système Terre dans l'Anthropocène", une étude récente cosignée par Will Steffen, chimiste réputé, analyste des systèmes climatiques et professeur de la science du Système Terre à l'Université nationale australienne, met en garde contre des changements catastrophiques du climat de la Terre si les tendances actuelles en matière d'émissions ne sont pas immédiatement inversées.
A new scientific paper proposing a scenario of unstoppable climate change has gone viral, thanks to its evocative description of a “Hothouse Earth”. Much of the media coverage suggests that we face an imminent and unavoidable extreme climate catastrophe. But as a climate scientist who has carried out similar research myself, I am aware that this latest work is a lot more nuanced than the headlines imply. So what does the hothouse paper actually say, and how did the authors draw their conclusions?
Famine, economic collapse, a sun that cooks us: What climate change could wreak — sooner than you think.
