As the climate warms, vegetation in far northern forests is changing as more trees and shrubs appear, according to new NASA research.

The Sahara Desert can be thought of as a vast expanse of barren sand, an extreme environment for plants and animals to thrive. But in fact, vegetation growth in the desert has waxed and waned over millennia, with periods of increased growth referred to as “green-up.”
Scientists have found that past Arctic ice melt has generated inflows of freshwater into the North Atlantic, which in turn have impacted global ocean circulation patterns.
An international team of astronomers has used the James Webb Space Telescope to detect the first brown dwarf candidates outside the Milky Way in the distant and mysterious star cluster.
A group of Spanish scientists has indicated that artificial wetlands can reduce the effects of agricultural waste, which can be exported to areas such as Doñana or the Mar Menor, as they also promote carbon capture and soil formation.
Atmospheric rivers are long and narrow tongues of water vapor, which are associated with clouds and abundant rainfall, and now it has been observed that they are moving to higher latitudes, and that is changing climate patterns around the world.
A new study highlights the importance of increased caution behind the wheel, especially on nights with a full moon, when the road is theoretically better visible than on dark, moonless nights. Why?
In a new study, the research team looked at whether consumers who buy and drive such vehicles have a smaller carbon footprint than other consumers who continue to drive gasoline-powered vehicles. The results are surprising.
NASA's Curiosity rover, currently exploring Gale Crater on Mars, is providing new details of how life on the planet could not have developed as we know it on Earth.
Scientists are observing and analyzing the consequences of the increase in "good" stratospheric ozone over much of 2024 in the Arctic, and are looking for reasons and trends for this increase in the future.
Atmospheric rivers are conveyor belts for high concentrations of water vapor/humidity and are precursors of potential floods when they reach land. A very intense and long-lasting river has recently developed.
A scientific study shows that iron bound to Sahara dust, which blows west over the Atlantic, has properties that change with distance traveled and is used by certain marine and terrestrial beings. It is the so-called bioreactive iron.
Photosynthesis, a process that requires sunlight, can occur even in extremely low light conditions, according to an international study that examined the development of Arctic microalgae at the end of the polar night.
Scientists find that more than 60% of the world's cities have more rainfall than surrounding rural areas and cities with taller buildings receive more rainfall than others with shorter buildings due to wind convergence.
It has been more than two weeks since Hurricane Ernesto formed, and as of today, the NHC does not forecast any new named storms within 7 days of peak hurricane season. This period would be the longest streak without the formation of a new named storm at the peak of hurricane season.
La Niña has been making her appearance during the summer of 2024, when she was expected, at least, as a weak to moderate phenomenon for the second part of 2024. Now it seems that the waters of the central equatorial Pacific are cooling at a rate that will make La Niña a reality very soon.
At the climatological peak of tropical cyclone activity, the Atlantic is relatively inactive with only two tropical waves and one of them could become a tropical depression or tropical storm as it heads toward the Caribbean and could subsequently impact southwestern Mexico.
An atmospheric river brought heavy rains to southern Alaska in early August 2024, triggering a large landslide and tsunami at Pedersen Lagoon.
New research from the University of Liverpool has revealed how an underwater avalanche grew more than 100 times in size, causing a huge trail of destruction as it cut 2,000km across the Atlantic Ocean seabed off the north-west coast of Africa and the north of the Canary Islands.
Researchers have discovered an unexpected increase in the abundance of two variants of water molecules in the mesosphere of Venus. This phenomenon challenges our understanding of the history of the water of Venus and the possibility that it was once habitable in the past.
