Arctic sea ice hits lowest peak in satellite record, says US agency
WASHINGTON (AFP) This year's Arctic sea ice peak is the lowest in the 47-year satellite record, the US National Snow and Ice Data Center (NSIDC) said Thursday, as the planet continues to swelter under the mounting effects of human-driven climate change.The start of this year saw the warmest January on record followed by the third-warmest February, with the polar regions heating several times faster than the global average.The 2025 maximum sea ice extent was likely reached on March 22, measuring 14.33 million square kilometers (5.53 million square miles) -- below the previous low of 14.41 million square kilometers set in 2017."This new record low is yet another indicator of how Arctic sea ice has fundamentally changed from earlier decades," said NSIDC senior research scientist Walt Meier in a statement. "But even more importantly than the record low is that this year adds yet another data point to the continuing long-term loss of Arctic sea ice in all seasons."The record-low Arctic maximum extent follows a near-record-low minimum extent of sea ice in the Antarctic, where it is now summer. The 2025 Antarctic sea ice minimum, achieved on March 1, was 1.98 million square kilometers, tying for the second-lowest annual minimum in the satellite record, alongside 2022 and 2024.
Combined Arctic and Antarctic sea ice cover -- frozen ocean water that floats on the surface -- plunged to a record low in February, according to both the US National Oceanic and Atmospheric Administration (NOAA) and Europe's Copernicus Climate Change Service.

European extreme-weather monitoring satellite launches into space
13 Aug 2025 14:01 KOUROU (AFP)The Ariane 6 rocket on Wednesday blasted off carrying Europe's next generation satellite for warning against extreme weather many European countries simmer in a deadly heatwave, the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) said its MetOp-SGA1 satellite will give "earlier warnings to help protect lives and property from extreme weather"."Metop-SGA1 observations will help meteorologists improve short- and medium-term weather models that can save lives by enabling early warnings of storms, heatwaves, and other disasters, and help farmers to protect crops, grid operators to manage energy supply, and pilots and sailors to navigate safely," the agency rocket carrying the four-tonne satellite took off from France's Kourou space base in French Guyana. MetOp-SGA1 was to be put into an 800 kilometre (500 mile) high will be Europe's first contribution to a US-led programme, the Joint Polar System, putting up satellites orbiting between the north and south six monitoring instruments on the satellite are twice as precise as the agency's existing satellite, IASI. It will monitor ocean and land temperatures, water vapour and greenhouse gases in the atmosphere, the amount of desert dust and cloud cover."Extreme weather has cost Europe hundreds of billions euros and tens of thousands of lives over the past 40 years -- storms like Boris, Daniel and Hans, record heatwaves and fierce wildfires are just the latest reminders," said Phil Evans, EUMETSAT director-general."The launch of Metop-SGA1 is a major step forward in giving national weather services in our member states sharper tools to save lives, protect property, and build resilience against the climate crisis." The liftoff was the third by Ariane 6 since its inaugural flight in July last year.

Swiss pilot surpasses solar-powered plane altitude record
13 Aug 2025 13:41 GENEVA (AFP)Swiss pilot Raphael Domjan beat the altitude record for a solar-powered electric plane in a flight that took him soaring to 9,521 metres, his team announced SolarStratos plane made the landmark flight from Sion airport in southwest Switzerland on Tuesday, taking advantage of warm air thermals to go beyond the 15-year-old certified altitude record for a solar plane had stood at 9,235 metres (30,298 feet). It was set in 2010 by the Solar Impulse plane, with Swiss pilot Andre Borschberg at the flight lasted five hours and nine minutes."I share this moment of joy with all the people who have been preparing for this achievement for years," he said, celebrating afterwards with the melted cheese of a traditional Swiss data will be sent to the World Air Sports Federation governing body, which will decide whether to validate the new record."It is the pressure altitude corrected to standard density altitude that is recognised as the official reference for aviation altitude records," the SolarStratos team said in a is aiming to be the first to take a solar-powered plane above 10,000 metres -- flying at the same altitude as this barrier is broken, the team hopes to go on and make a first manned solar-powered flight into the stratosphere, which at Switzerland's latitude begins at around 12,000 metres. "This achievement marks a major milestone on the path toward reaching the stratosphere using only solar power -- and already fulfils the mission's goal: to capture imaginations with emblematic, spectacular challenges that promote solar energy and the protection of our biosphere and planet," SolarStratos said.

US astronaut Jim Lovell, commander of Apollo 13, dead at 97
9 Aug 2025 10:26 WASHINGTON (AFP)US astronaut Jim Lovell, the commander of the Apollo 13 Moon mission which nearly ended in disaster in 1970 after a mid-flight explosion, has died at the age of 97, NASA announced former Navy pilot, who was portrayed by actor Tom Hanks in the 1995 movie "Apollo 13," died in a Chicago suburb on Thursday, the US space agency said in a astronaut's "life and work inspired millions of people across the decades," NASA said, praising his "character and steadfast courage."Lovell travelled to the Moon twice but never walked on the lunar he is considered one of the greats of the US space program after rescuing a mission that teetered on the brink of disaster as the world watched in suspense far below."There are people who dare, who dream, and who lead others to the places we would not go on our own," Hanks said in an Instagram post."Jim Lovell, who for a long while had gone farther into space and for longer than any other person of our planet, was that kind of guy."'Houston, we've had a problem'Launched on April 11, 1970 -- nine months after Neil Armstrong became the first person to walk on the Moon -- Apollo 13 was intended to be humanity's third lunar plan was that Lovell would walk on the mission, which was also crewed by astronauts Jack Swigert and Fred Haise, was already considered fairly an oxygen tank exploded on the way disaster prompted Swigert to famously tell mission control: "Houston, we've had a problem."Lovell then repeated the phrase, which is slightly different to the one used in the Ron Howard movie, according to three astronauts and crew on the ground scrambled to find a United States followed the chaotic odyssey from the ground, fearing that the country could lose its first astronauts in 200,000 miles from Earth, the crew was forced to shelter in their Lunar Module, slingshot around the Moon and rapidly return to composed leadership of Lovell -- who was nicknamed "Smilin' Jim" -- and the ingenuity of the NASA team on the ground managed to get the crew safely back was awarded the Presidential Medal of Freedom, but never returned to on March 25, 1928 in Cleveland, Ohio, Lovell worked as a Navy pilot before joining NASA. He was one of three astronauts who became the first people to orbit the Moon during the Apollo 8 mission in 1968. The mission also took the famous image "Earthrise," in which the blue planet peeks out from beyond the Moon.
