Increases in airborne pollution have dimmed the skies over most of the world during the past 30 years by blocking sunlight, researchers report in Friday’s edition of the journal Science.
While decreases in atmospheric visibility, known as global dimming, have been reported in the past, the new study compiles satellite and land-based data for a longer period than had been available.
“Creation of this database is a big step forward for researching long-term changes in air pollution and correlating these with climate change,” Kaicun Wang, assistant research scientist in the University of Maryland, said in a statement. “And it is the first time we have gotten global long-term aerosol information over land to go with information already available on aerosol measurements over the world’s oceans.”
They reported that dimming is occurring everywhere except Europe, where declines in pollution have resulted in brighter skies.
Changes in aerosols can affect weather and also may have an impact on climate, although past studies have been inconclusive.
These pollutants can result in cooling by reflecting sunlight back into space, but they also can absorb solar energy and warm the atmosphere.
Researchers at the National Oceanic and Atmospheric Administration , meanwhile, warned that suggestions for a high-atmosphere “sunshade” of particles to battle global warming could reduce energy production from solar power plants.
Those proposals are aimed at blocking sunlight that can be absorbed by so-called greenhouse gases like carbon dioxide, warming climate.
Indonesia yesterday began enforcing its newly ratified penal code, replacing a Dutch-era criminal law that had governed the country for more than 80 years and marking a major shift in its legal landscape. Since proclaiming independence in 1945, the Southeast Asian country had continued to operate under a colonial framework widely criticized as outdated and misaligned with Indonesia’s social values. Efforts to revise the code stalled for decades as lawmakers debated how to balance human rights, religious norms and local traditions in the world’s most populous Muslim-majority nation. The 345-page Indonesian Penal Code, known as the KUHP, was passed in 2022. It
US President Donald Trump on Friday said Washington was “locked and loaded” to respond if Iran killed protesters, prompting Tehran to warn that intervention would destabilize the region. Protesters and security forces on Thursday clashed in several Iranian cities, with six people reported killed, the first deaths since the unrest escalated. Shopkeepers in Tehran on Sunday last week went on strike over high prices and economic stagnation, actions that have since spread into a protest movement that has swept into other parts of the country. If Iran “violently kills peaceful protesters, which is their custom, the United States of America will come to
Auschwitz survivor Eva Schloss, the stepsister of teenage diarist Anne Frank and a tireless educator about the horrors of the Holocaust, has died. She was 96. The Anne Frank Trust UK, of which Schloss was honorary president, said she died on Saturday in London, where she lived. Britain’s King Charles III said he was “privileged and proud” to have known Schloss, who cofounded the charitable trust to help young people challenge prejudice. “The horrors that she endured as a young woman are impossible to comprehend and yet she devoted the rest of her life to overcoming hatred and prejudice, promoting kindness, courage, understanding
‘DISRESPECTFUL’: Katie Miller, the wife of Trump’s most influential adviser, drew ire by posting an image of Greenland in the colors of the US flag, captioning it ‘SOON’ US President Donald Trump on Sunday doubled down on his claim that Greenland should become part of the US, despite calls by the Danish prime minister to stop “threatening” the territory. Washington’s military intervention in Venezuela has reignited fears for Greenland, which Trump has repeatedly said he wants to annex, given its strategic location in the arctic. While aboard Air Force One en route to Washington, Trump reiterated the goal. “We need Greenland from the standpoint of national security, and Denmark is not going to be able to do it,” he said in response to a reporter’s question. “We’ll worry about Greenland in
