Oxygen atoms in 15‑million‑year‑old giant eggshells reveal how plants reacted to a hotter
Some periods in Earth's history are so different from our own that they may as well belong to another planet. Many people are interested in the age of dinosaurs or the Ice Ages, but it is an intermediate world, the Miocene Epoch—a sort of "in-between" world, geologically speaking
Cosmic dust could play key role in cracking long-standing mystery of solar corona heating
A researcher at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a new study in The Astrophysical Journal suggesting that tiny charged dust grains near the sun may significantly influence how energy moves through the solar c
What makes a star a star? A strange 'in‑between' celestial object is testing astronomers'
A star called TOI-2155 lies around 1,350 light-years (839 trillion miles) from Earth. It is a little bigger, heavier and hotter than the sun, and it is not particularly interesting or unusual in itself.
We can't air-condition our way out of a hotter future, says expert
As temperatures rise around the world, air conditioning is saving lives. But a growing reliance on it is also placing unprecedented pressure on electricity grids, increasing greenhouse gas emissions and making cities even hotter.
'Hotter and hotter and hotter' - Europe's new climate in seven charts
Temperature records were smashed in June - and scientists warn this is a sign of things to come. O recorte ajuda a contextualizar a pauta dentro de Agro.
Block-by-block AI maps uncover real urban air temperatures across 380 U.S. cities
Cities are often described as "heat islands," with media reports warning that some neighborhoods can be 20° F (7° C) hotter than others. But those temperatures are often based on satellite data rather than the conditions people actually experience, due to the dearth of near-surfa
Why does hot weather put me in such a bad mood?
Not everyone experiences heat the same way, and studies show aggression, violence and road rage increase on hotter daysRecently, my husband and I embarked on what should have been a pleasant spring errand: a stroll to the local farmer’s market. But a passing heatwave had made it
Trees for hotter cities: New approach can bolster community input in meeting targets
Efforts to plant more trees in cities could be boosted thanks to a new tool for planners and community groups, published by an international group of researchers. Residents, policymakers and tree officers in Cardiff, Milton Keynes, Edinburgh, York and Camden worked with academics
Planes sent to tackle wildfires of 'exceptional scale' near Paris
It was the first time firefighting planes had been sent up from the normally drier and hotter south of the country to tackle fires in the Paris region.
Study reveals Hawaiian hotspot is getting hotter
Contrary to conventional geological thinking, the Hawaiian mantle plume has gotten hotter by about 250°C (480°F) over the past 47 million years. This discovery, led by Earth scientists at the University of Hawai'i at Mānoa, reverses the long-held idea that hotspots start out very
