Climate engineering poses serious national security risks; countries facing extreme heat can try anyway, and the world must be prepared
One of the biggest concerns for many countries when it comes to climate change is national security. That doesn’t just mean wars. Risks to food, energy and water supplies are national security issues, as is climate-induced migration. Could climate engineering help reduce national security risks from climate change, or would it just make things worse? … Read more
Climate engineering poses serious national security risks; countries facing extreme heat can try anyway, and the world must be prepared
The historic Paris climate agreement ushered in a mantra for developing countries: “1.5 to stay alive.” It refers to the international goal of keeping global warming below 1.5 degrees Celsius (2.8 Fahrenheit) compared to pre-industrial times. But the world will likely cross that threshold within a decade, and global warming shows little sign of slowing. … Read more
Melting polar ice is slowing the Earth’s rotation, potentially affecting timekeeping
Global warming has slowed the Earth’s rotation slightly – and this could affect the way we measure time. A study published Wednesday shows that the melting of Arctic ice — an accelerating trend caused mainly by human-induced climate change — has caused the Earth to spin less quickly than it would otherwise. The study’s author, … Read more
Planet not at risk of ‘CO2 famine’: scientists
A screenshot of the misleading graph, captured on March 5. Kate TAN Similar reports from New Zealand and France include a 37-second video clip of an interview with William Happer, a professor of physics at Princeton University, broadcast by Sky News Australia in September 2023. Happer, formerly a scientific adviser to former US President Donald … Read more
The Atlantic Ocean is heading to a tipping point – once melting glaciers shut off the Gulf Stream, we would see extreme climate change within decades, research shows
Super storms, abrupt climate shifts and New York City frozen in ice. For example, the blockbuster Hollywood film “The Day After Tomorrow” depicted an abrupt cessation of the circulation of the Atlantic Ocean and its catastrophic consequences. Although Hollywood’s vision was exaggerated, the 2004 film raised a serious question: If global warming halts the Atlantic … Read more
The world has successfully tackled a dangerous pollutant. But did it accidentally warm the planet in the process?
The enormous cargo ships that traverse the world’s oceans sometimes leave behind “trails”: long, wispy clouds that travel across the sky and last for at most a few days before disappearing. These ghost clouds look beautiful, but they are a visible sign of deadly air pollution. They are formed when tiny sulfur dioxide particles belched … Read more
