The signature of La Niña is visible in the central and eastern Pacific Ocean as areas with below-average water levels and, at the same time, modifies precipitation and wind conditions in large areas of the basin.

Astronomers are observing daily re-entries of artificial satellites that are unprecedented to date and this has consequences for atmospheric layers as well as the ozone layer. The problem will only get worse.
PFAS are highly polluting, long-lasting anthropogenic products and scientists have problems eliminating them once they are in the environment. But a simple solution could be close at hand.
According to some scientists, the surpassing of 1.5 °C of warming much earlier than we imagined is partly due to what is happening above the Arctic Circle.
How bad can a solar storm be? Just ask a tree. Unlike human records, which go back hundreds of years, trees can remember solar storms for millennia: these are the Miyake events, far more intense than the Carrington Event of 1859.
Astronomers have discovered a 60-metre-wide asteroid with a low but not negligible probability of impacting Earth in late 2032. There are still some uncertainties regarding its final trajectory and approach to our planet.
Scientists have made an important discovery as the Arctic ice melts due to anthropogenic warming: parts of the Arctic are going from being a sink for CO₂ to being a source of this powerful greenhouse gas.
13,000 years ago, Central Europe experienced a period of extreme cold that scientists have detected in climate records and which is now confirmed to have occurred 150 years earlier than previously thought.
Why do many people live in risky areas over and over again? There are compelling reasons, even for people with high purchasing power, as is the case in areas like Los Angeles, which is currently suffering from deadly and destructive wildfires.
For decades, scientists have struggled to accurately predict solar flares—intense bursts of light from the Sun that can send a surge of charged particles into the solar system. Now, signals that precede these flares have been detected.
Researchers have documented for the first time the systematic occupation of African equatorial rainforests by Homo sapiens more than 40,000 years ago.
A study led by researchers presents the oldest known example in the fossil record of an evolutionary arms race that played out in marine waters millions of years ago.
The Earth has been warming for decades, but recently there has been an extraordinary rise in temperatures in the atmosphere and oceans and scientists are still trying to figure out the reasons, and 2025 is on track.
The maximum number of sunspots in solar cycle 25 was reached in late November and early December 2024, and it remains more active than expected. What awaits us in 2025? Experts tell us about it and its impacts.
A new model suggests how gold from deep underground can emerge in layers close to the Earth's surface and thus be extracted.
Astronomers are studying a galaxy that appears to be staring at us from afar using data and images from the Hubble Space Telescope.
A new NASA-led study has found that how rain falls in a given year is almost as important to the world's vegetation as how much.
Scientists say that over the past four years, the annual ozone hole over Antarctica has remained open for longer than usual and closed in the second half of December 2024, according to Copernicus data.
The Arctic is characterised by its cold, harsh climate and limited daylight hours during the winter. But this typically frigid region is warming about four times faster than the rest of the planet, which has facilitated increased transport and development.
Where does water in Earth's oceans come from? It is an open question that has scientists constantly researching, and comets may have part of the answer.
