The world's top court may not be able to compel states to halt planet-warming emissions, but experts say its momentous climate decision gives potent political firepower to campaigners. https://www.japantimes.co.jp/environment/2025/07/26/climate-change/world-court-climate-ruling-focus/?utm_medium=Social&utm_source=mastodon #environment #climatechange #climatechange #icj #emissions #environment #parisagreement

The world’s oceans experienced a staggering amount of warming in 2023, as vast marine heat waves affected 96% of their surface, breaking records for intensity, longevity and scale, according to a new study. https://www.japantimes.co.jp/environment/2025/07/25/climate-change/oceans-tipping-point/?utm_medium=Social&utm_source=mastodon #environment #climatechange #oceans #climatechange #emissions

Motor racing, a sport known for flashy, petrol-guzzling racecars speeding at hundreds of kilometers per hour, hasn’t been a pastime known for sustainability. Formula 1 is trying to change that. https://www.japantimes.co.jp/sports/2025/07/25/more-sports/formula-1-carbon-footprint/?utm_medium=Social&utm_source=mastodon #moresports #formulaone #climatechange #emissions #environment

With cooling demand increasing as the planet warms, concern is growing over highly polluting refrigerants. Enter the Recoolit startup. https://www.japantimes.co.jp/environment/2025/07/10/climate-change/indonesia-startup-coolants-global-warming/?utm_medium=Social&utm_source=mastodon #environment #climatechange #indonesia #startups #climatechange #emissions

Another big jump in atmospheric CO₂ measured at Mauna Loa*: based on daily values, the June average was ~429.7 ppm, that's 2.8 ppm higher than last year!

The heat wave searing Europe is making a compelling case for one of the most ambitious climate targets ever set by Brussels. Many in the European Union, however, have yet to be convinced. https://www.japantimes.co.jp/environment/2025/07/02/climate-change/europe-climate-eu-2040-goal/?utm_medium=Social&utm_source=mastodon #environment #climatechange #europe #climatechange #eu #carbon #emissions

The fast-rising energy demands of Big Tech are undermining the ambitious climate pledges that Apple, Amazon, Google, Meta and Microsoft have all made in recent years, according to a report. https://www.japantimes.co.jp/business/2025/06/30/tech/ai-data-center-net-zero/?utm_medium=Social&utm_source=mastodon #business #tech #ai #tech #emissions #netzero #bigtech #environment #climatechange #apple #amazon #google #meta #microsoft

An interesting study which looks at #CO2 #emissions produced by various #AI models

#ArtificialIntelligence

We did the math on #AI’s energy footprint. Here’s the story you haven’t heard.
The #emissions from individual AI text, image, and video queries seem small—until you add up what the industry isn’t tracking and consider where it’s heading next.
The latest reports show that 4.4% of all the energy in the #US now goes toward #datacenters. The #carbon intensity of #electricity used by data centers was 48% higher than the US average.
