Four jet-black spheres clung to a rock on the Pacific seafloor at roughly 20,300 feet, stopping a research crew in its tracks. They looked like eggs, but their color, shape, and shine felt off-script for the deep ocean. Back on deck the mystery held. These were not fish eggs at all but hard little capsules called cocoons, each sheltering several …

The timing of Earth’s seasons is no longer unfolding uniformly across the globe. A new satellite-based study published in Nature reveals surprising disparities in plant growth cycles, uncovering regions where ecosystems just kilometers apart follow different seasonal rhythms. What was once considered a predictable annual cycle is far more complex than previously thought. By analyzing two decades of satellite data, …

The planet’s capacity to store carbon-dioxide emissions in rock formations is much smaller than previous estimates suggest and it could run out as early as 2200, according to a study1 published in Nature today. To meet the goal of the 2015 Paris agreement — limiting global warming to 1.5–2 °C above pre-industrial temperatures — vast amounts of CO2 will need …

As early as 2024, scientists from the US and China discovered that the Earth’s core had slowed down and even stopped moving in relation to the Earth’s crust. But until now, the general public—that’s people like you and me—has barely noticed this remarkable change. The Earth’s core is comprised of metals and, as the name suggests, makes up the interior …

A new global study warns that most of Earth’s land is already beyond safe ecological limits, with far-reaching consequences for climate, ecosystems, and humanity’s future. Credit: Stock Sixty percent of global land is outside safe biosphere limits, with human use of biomass driving widespread ecological strain. A new study provides the first detailed mapping of the planetary boundary known as …

Ever since its formation around 4.5 billion years ago, Earth’s rotation has been gradually slowing down, and its days have gotten progressively longer as a result. While Earth’s slowdown is not noticeable on human timescales, it’s enough to work significant changes over eons. One of those changes is perhaps the most significant of all, at least to us: lengthening days …

According to a recent study, events geologists use to distinguish transitions between geological chapters in Earth’s story follow a hidden hierarchical pattern, one that could shed light on both past and future tumult. “Geological time scales may look like tidy timelines in textbooks, but their boundaries tell a much more chaotic story,” says study co-author Andrej Spiridonov, a geologist and …

The annual clock of the seasons – winter, spring, summer, autumn – is often taken as a given. But our new study in Nature, using a new approach for observing seasonal growth cycles from satellites, shows that this notion is far too simple. We present an unprecedented and intimate portrait of the seasonal cycles of Earth’s land-based ecosystems. This reveals …
