Almond trees bloom early in Spain due to unseasonal warmth and climate change
Almond trees in northeastern Spain started to bloom in late January, nearly three weeks earlier than usual.
Climate change is threatening the sustainability of low Earth orbit, with new research from MIT revealing that shrinking atmospheric layers could significantly reduce the number of satellites able to operate safely by the end of the century.
Climate change is altering the environment of near-Earth space in ways that could significantly reduce the number of satellites able to safely operate in low Earth orbit by the century's end, according to a new study by the Massachusetts Institute of Technology (MIT), as reported by Anadolu Agency.
Published in Nature Sustainability on Monday, the research reveals that greenhouse gas emissions are causing the upper atmosphere, particularly the thermosphere, to shrink. This is the region where the International Space Station and most satellites orbit.
As the thermosphere contracts, the thinning air reduces the natural drag that typically slows down old satellites and space debris, causing them to re-enter the atmosphere and burn up. With less drag, defunct satellites and space junk will remain in orbit for much longer, increasing collision risks and overcrowding in low Earth orbit.
Researchers project that by 2100, the capacity of key orbital regions could decrease by 50%-66% if emissions continue to rise. The study highlights the urgent need for emission reductions and careful management of satellite launches.
NASA astronauts Butch Wilmore and Suni Williams completed an unexpectedly long 286-day mission on the ISS, returning to Earth aboard a SpaceX capsule after delays caused by technical issues with Boeing’s Starliner.
In a groundbreaking study published in Cell on January 18, Chinese researchers have unveiled a novel cancer treatment that ingeniously disguises tumors as pig tissue, triggering the body’s immune system to mount a hyperacute rejection response against the cancer cells.
Russian President Vladimir Putin agreed on Tuesday to a proposal by U.S. President Donald Trump that Russia and Ukraine cease attacking each other's energy infrastructure for 30 days, the Kremlin said following a lengthy phone discussion between the leaders.
On March 16, at around 09:45, Armenian armed forces opened fire on Azerbaijani positions located in the direction of the Digh settlement in the Goris region, using firearms, according to Azerbaijan's Ministry of Defence.
Sweden’s Prime Minister Ulf Kristersson stated on Thursday that purchasing U.S. weapons does not pose a security risk for his country, but emphasized the need for Europe to reduce its reliance on American defense systems. His comments come amid growing discussions within Europe.
Glaciers around the world are melting at an alarming rate, with the last three years seeing the largest mass loss on record, according to a UNESCO report. The accelerated ice loss, driven by climate change, is contributing to rising sea levels.
Record greenhouse gas levels in 2024 have driven global temperatures to an all-time high, accelerating the loss of glaciers and sea ice, raising sea levels, and bringing the world closer to a key climate threshold, according to the World Meteorological Organization (WMO).
Zara owner Inditex reported a 10% rise in transport emissions in 2024, driven by increased air freight to avoid shipping delays caused by Red Sea disruptions. While the retailer made progress in reducing sourcing-related emissions, it faces challenges in meeting its long-term climate targets.
Ireland has committed €15 million ($16.3 million) to Brazil's Amazon Fund over the next three years, aiming to support efforts to combat deforestation in the world's largest tropical rainforest.
