Al Gore on China’s climate rise: ‘I would not have seen this coming’

techcrunch.com Connie Loizos 2025-09-23 05:00:00

Twenty-five years ago, Al Gore was in the final stretch of his U.S. presidential campaign, just weeks away from an election that would ultimately slip through his fingers despite winning the popular vote. His platform included ambitious climate action, with America positioned as the natural leader of a global environmental transition. The irony of what has transpired since is not lost on him. “Looking from the standpoint of 25 years ago, I have to say no, I would not have seen this as the most

Study Directly Links Emissions from Fossil Fuel Producers to Devastating Heatwaves

gizmodo.com Ellyn Lapointe 2025-10-01 01:14:12

A new study directly links hundreds of major heatwaves since 2000 to the emissions from fossil fuel and cement producers. Among its fundings, the researchers conclude that as many as a quarter of all heatwaves since the start of this century would have been “virtually impossible” without emissions from any of the world’s 14 largest fossil fuel and cement producers. The study, published Wednesday in the journal Nature, shows that greenhouse gas emissions from 180 of the world’s biggest cement, o

Not so fast: German court says Apple can’t call Watch carbon neutral

techcrunch.com Tim De Chant 2025-10-28 04:35:27

Two years ago, Apple announced its Watch Series 9 as its first carbon-neutral product. From cradle to grave, the company said the manufacturing, use, and disposal of the then-new model didn’t contribute to global warming. Now, a German court says that Apple has to recant the claim. Each aluminum Apple Watch Series 9 and Series 10 — two models with the carbon-neutral designation — generates just over 8 kilograms of carbon emissions. Apple then offsets those emissions through the purchase of car

Lightning declines over shipping lanes following regulation of sulfur emissions

If you look at a map of lightning near the Port of Singapore, you’ll notice an odd streak of intense lightning activity right over the busiest shipping lane in the world. As it turns out, the lightning really is responding to the ships, or rather the tiny particles they emit. Using data from a global lightning detection network, my colleagues and I have been studying how exhaust plumes from ships are associated with an increase in the frequency of lightning.

Why recycling isn’t enough to address the plastic problem

technologyreview.com Casey Crownhart 2025-11-05 09:00:00

And looking into the future, emissions from plastics are only set to grow. Another estimate, from the Organisation for Economic Co-operation and Development, projects that emissions from plastics could swell from about 2 billion metric tons to 4 billion metric tons by 2060. This chart is what really strikes me and makes the conclusion of the plastic treaty talks such a disappointment. Recycling is a great tool, and new methods could make it possible to recycle more plastics and make it easier

When it comes to personal contributions to climate change, most Americans seem to have no clue how damaging some of their individual actions can be. Folks who happily recycle and switch to more energy-efficient appliances, per a recent study published in the Proceedings of the National Academy of Sciences Nexus journal, likely have a far larger carbon footprint than they realize.

Apple’s AI Ambitions Leave Big Questions Over Its Climate Goals

Here’s a simple question: Is the current top iPhone better for the environment than the top iPhone was five years ago? Let’s take the iPhone Pro series. If we’re looking at recycled and renewable materials, it’s an easy yes. Compare the iPhone 11 Pro, released in September 2019, with the iPhone 16 Pro, released in September 2024, and there has been good progress—from a few smaller components and packaging to now at more than 25 percent of the whole phone.

Last week, Mark Zuckerberg declared that Meta aims to achieve smarter-than-human AI.

The greenhouse gases we’re not accounting for

Researchers around the world set to work unraveling the mystery, reviewing readings from satellites, aircraft, and greenhouse-gas monitoring stations. They eventually spotted a clear pattern: Methane emissions had increased sharply across the tropics, where wetlands were growing wetter and warmer. That created the ideal conditions for microbes that thrive in anaerobic muck, which gobbled up more of the carbon-rich organic matter and spat out more methane as a by-product.

Amazon’s AI push is undermining its sustainability goals

Amazon’s decarbonization goals are being undermined by its push to be a leader in generative AI. Its most recent sustainability report concedes its overall carbon emissions grew for the first time since 2022. It reported a six percent increase in its carbon footprint across 2024, laying much of the blame at the feet of its data center rollout.

Shipping has a pollution problem, but one company has a solution that does more than just eliminate a boat’s carbon dioxide. London-based Seabound has developed a carbon capture system that transforms CO 2 from the engine into limestone, a key ingredient in cement. Fittingly, the company has installed it aboard the UBC Cork, a cement carrier currently sailing through the Mediterranean Sea.

Google’s carbon emissions just went up again

Google’s carbon emissions jumped yet again as the company continues to push ahead in AI. The company’s 2025 sustainability report emphasizes that its “ambition-based emissions” grew 11 percent last year to reach 11.5 million metric tons of carbon dioxide pollution, marking a 51 percent increase compared to 2019.

Methane Pollution Has Cheap, Effective Solutions That Aren’t Being Used

This story originally appeared on Vox and is part of the Climate Desk collaboration. Odorless and colorless, methane is a gas that is easy to miss—but it’s one of the most important contributors to global warming. It can trap up to 84 times as much heat as carbon dioxide in the atmosphere, though it breaks down much faster. Measured over 100 years, its warming effect is about 30 times that of an equivalent amount of carbon dioxide. That means that over the course of decades, it takes smaller a

Why Some AI Models Spew 50 Times More Greenhouse Gas to Answer the Same Question

Like it or not, large language models have quickly become embedded into our lives. And due to their intense energy and water needs, they might also be causing us to spiral even faster into climate chaos. Some LLMs, though, might be releasing more planet-warming pollution than others, a new study finds. Queries made to some models generate up to 50 times more carbon emissions than others, according to a new study published in Frontiers in Communication. Unfortunately, and perhaps unsurprisingly,

Demand in the other 40 states declined by about 3% over the same period.
