Methane emissions from Siberia have more than doubled over the past decade, according to new research co-led by scientists at the University of Edinburgh’s National Centre for Earth Observation (NCEO)

Exclusive: Commission says alert would trigger coordinated international response that could help avoid millions dying. The climate crisis should be declared a global public health emergency by the World Health Organization, or millions more people will die unnecessarily, leading international experts have said. The independent pan-European commission on climate and health, which was convened by the WHO, concluded the climate crisis was such a worldwide threat to health that the WHO should declare it “a public health emergency of international concern” (Pheic).

GLOBAL TIPPING POINTS REPORT - 2025

GLOBAL TIPPING POINTS REPORT 2025 - Summary

Why is the Trump Administration trying to kill a small space science institute in New York City? Explanation begins with Galileo’s method of scientific inquiry and ends with the role of special interest money in the United States government. Galileo improved the telescope, allowing clearer observations of the planets and the Sun. Galileo differed from his peers, as he was unafraid to challenge authority. He claimed that the world should be understood based on observations, and he spoke directly to the public. He obtained philanthropic support for his observations and openly described the conclusion that Earth was not the center of the solar system – Earth revolved around the Sun.

Extreme heat ‘the new normal’, says UN chief, as authorities across the continent issue health warnings

Outgoing special rapporteur David Boyd says ‘there’s something wrong with our brains that we can’t understand how grave this is’

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.

ibrio are bacteria that cause an estimated 80,000 illnesses each year in the United States. About a dozen species of Vibrio are pathogenic to humans. V. parahaemolyticus causes the most infections in the United States, accounting for about 40% of reported cases of vibriosis, followed by V. alginolyticus, which accounts for about 20%. Most people with Vibrio infection have diarrhea. Some people might also have stomach cramping, nausea, vomiting, fever, and chills. One species, V. vulnificus, is known to cause life-threatening infections. About 150–200 V. vulnificus infections are reported to CDC each year and about one in five people with this infection die—sometimes within 1–2 days of becoming ill.

The UN Secretary-General’s Early Warnings for All Initiative (EW4All) is rapidly gaining ground. Action plans are being rolled out around the world to ensure that people know when dangerous weather is headed their way. Tajikistan has held a two-day national consultation, co-chaired by the Deputy Prime Minister and the UN Resident Coordinator in Tajikistan, and bringing together key stakeholders from state and international organizations, media and civil society. Ethiopia also held an inception workshop.

La Niña is present.* Equatorial sea surface temperatures (SSTs) are below average across most of the Pacific Ocean. The tropical Pacific atmosphere is consistent with La Niña. La Niña is expected to continue into the winter, with equal chances of La Niña and ENSO-neutral during January-March 2023. In February-April 2023, there is a 71% chance of ENSO-neutral.*

A new analysis of flash droughts finds that droughts coming on suddenly seem to be striking faster in the last two decades, with approximately 33–46 percent of flash droughts now emerging within just five days.

The term 'microplastic' was coined just 18 years ago, but already they seem to be just about everywhere. Each year, the average human consumes an estimated 74,000 particles of plastic with unknown health effects. In March of this year, scientists announced they'd found microplastics flowing through our very veins.

Patagonian ice fields are among some of the fastest-melting glaciers on the planet. As these glaciers disappear, the earth that once lay beneath them is rebounding upwards at rates much faster than expected.

The accelerating melting of the Himalayan glaciers threatens the water supply of millions of people in Asia, new research warns.

Hugo Tagholm can clear a beach in minutes. He issues a raw sewage alert and everyone races out of the water. Swimmers hate sewage as much as sharks — no one wants to splash about in excrement. But even Tagholm gets it wrong sometimes and finds himself surfing a brown wave. “It’s pretty unpleasant paddling through effluent,” he says. “I avoid it at all costs.”

ome problems are so big, you can't really see them. Climate change is the perfect example. The basics are simple: the climate is heating up due to fossil fuel use. But the nitty gritty is so vast and complicated that our understanding of it is always evolving. Evolving so rapidly, in fact, that it's basically impossible for humans to keep up.

If Earth had a pulse, it might be The Atlantic Meridional Overturning Circulation (AMOC) – a swirl of ocean currents that carries tropical heat north towards polar waters. Over the past century this global heartbeat has eased, slowing to a speed not seen in more than a millennium. New research based on a range of indices has now bolstered views that the weakening isn't a trivial one, and critical transition is imminent.

Abrupt disruptions to Earth's climate thousands of years ago that caused extreme sea-level rise and mass ice cap melting can serve as an early warning system for today's planetary tipping points, according to new research.

Climate change and deforestation have flipped a large swathe of the Amazon basin from absorbing to emitting planet-warming carbon dioxide (CO2), a transformation that could turn humanity's greatest natural ally in the fight against global warming into a foe, researchers reported on Wednesday.
