Study Reveals Atlantic Ocean's Warming Threshold Depends on Speed of Change

The Atlantic Ocean has more capacity to absorb warming than previously thought—but only if that warming occurs gradually, according to new research. Scientists studying the Atlantic Meridional Overturning Circulation (AMOC) have discovered that the ocean system responds differently depending on the speed of temperature change. When warming happens slowly,

Laser Surveys Uncover Evidence of a Massive Ancient Civilization in the Amazon

New laser-based surveys are reshaping our understanding of the Amazon's past. Researchers using airborne LiDAR (Light Detection and Ranging) technology have uncovered hundreds of ancient earthworks hidden beneath the rainforest canopy—structures invisible to the ground-level surveys that dominated archaeology for decades. The findings suggest that parts of

Form Energy Secures $750M to Scale 100-Hour Grid Battery Production

Form Energy has closed a $750 million funding round to accelerate production of its iron-air batteries designed to store electricity for up to 100 hours—significantly longer than typical lithium-ion grid storage systems that typically provide 4–8 hours of capacity. The company, which counts Google and cloud infrastructure provider

Tracking Extreme Heat by the Hour Makes Climate Change Seem Even Worse

Traditional climate analysis has long relied on daily average temperatures, but a growing body of research suggests that looking at heat exposure hour by hour provides a clearer picture of how climate change affects people and ecosystems. This hourly approach reveals patterns that daily averages obscure. When scientists examine temperature

Research Suggests AI Could Increase Fossil Fuel Emissions by Nearly 5%

A recent research study is raising concerns about an unintended consequence of artificial intelligence adoption in the energy sector. The findings suggest that by making the fossil fuel industry more productive, AI could paradoxically drive carbon emissions upward rather than curbing them. The research indicates that AI-enabled efficiency gains in

China Accelerates AI Weather Forecasting as Extreme Events Rise

China is ramping up its deployment of artificial intelligence systems for weather forecasting, driven by the growing intensity and frequency of extreme weather events across the country. As climate change amplifies storms, floods, heatwaves, and other severe conditions, traditional forecasting methods are being supplemented—and in some cases replaced—by

Amazon's Off-Grid AI Data Center Highlights Tension Between Cloud AI Expansion and Climate Commitments

Amazon has revealed plans for its first self-sufficient data center, designed to operate independently from the broader electrical grid. The facility will be powered by a newly funded natural gas power plant that is projected to become one of the largest sources of greenhouse gas emissions in the United States.
