As it looks increasingly unlikely we’re going to meet our climate mitigation targets, scientists have been investigating more and more extreme solutions, such as geoengineering. Examples include spraying huge amounts of sunlight-reflecting particles into the atmosphere, or dumping trillions of tons of fake snow onto glaciers to stabilise them. These ideas are untested, incredibly risky,

Pacific islanders are running out of time. If global emissions are not drastically reduced, thousands of low-lying atolls may become uninhabitable within decades. And the biggest threat doesn’t actually come from losing land to rising seas. Small island states in the Pacific are responsible for only 0.03 percent of the world’s carbon dioxide emissions, and

It’s springtime Down Under, and along with overexuberant local football fans, that means another annual menace on Australian streets: angry birds. September is peak magpie breeding season. And like much of Australia’s native wildlife — think deadly snakes, spiders and jellyfish — the country’s magpies are meaner than those found elsewhere. Male birds defending their

Hopes of a breakthrough in international climate change ambitions are being downplayed for a landmark meeting in New York. The United Nations climate action summit looks set to disappoint the thousands of campaigners who will take to the city’s streets just days earlier. The summit is arguably the most important moment for climate change since

A 16-year-old Swedish climate activist demanded Wednesday that Congress “listen to the scientists” who were sounding the alarm on the threat of global warming. Rather than offer prepared remarks to the House Climate Crisis Committee and a House Foreign Affairs subcommittee, Greta Thunberg said she was attaching as testimony a landmark 2018 United Nations report

Last month, we got the exciting news of a rare flash of light on Jupiter, bright enough to be seen through telescopes. According to a new analysis, the cause of this smash was a small asteroid, with a density consistent with meteors that are equal parts stone and iron. The meteor exploded in Jupiter’s upper

On its surface, the plan was simple: gene-hack mosquitoes so their offspring immediately die, mix them with disease-spreading bugs in the wild, and watch the population drop off. Unfortunately, that didn’t quite pan out. The genetically-altered mosquitoes did mix with the wild population, and for a brief period the number of mosquitoes in Jacobino, Brazil

The Northern Hemisphere just had its hottest summer on record since 1880, according to National Oceanic and Atmospheric Administration data released Monday. NOAA found the average global surface temperature taken by thousands of thermometers, buoys and other sensors on land and sea tied with that of 2016 for the top spot, with a temperature anomaly

A small group of super-powerful corporations has become a dominant force that essentially controls human industry and shapes the modern world we live in, scientists say. In a new study, an international team of researchers suggests that this elite cadre of dominant transnational corporations (TNCs, sometimes also called multinationals) may wield an outsized influence over

According to new research, the dead may not always rest in peace… quite literally. For more than a year after death, corpses move around “significantly”, and this finding could be important for forensic investigations. Researchers at an Australia-based decomposition research facility – colloquially known as a “body farm”, a term some scientists find disrespectful –
