The Snowy 2.0 Pumped Storage Power Station – simply known as Snowy 2.0 – is a giant power generation project in Australia that is designed to supply 2.2 gigawatts of capacity and 350,000 megawatt-hours of large-scale energy storage to the national electricity market. The massive storage capacity will enable the introduction of more wind and solar generation by acting like a giant battery.

Africa’s forests were once among the world’s largest carbon sinks, absorbing roughly 20% of all the carbon dioxide captured by plants. For centuries, the continent’s rainforests and woodlands helped regulate the planet’s climate, acting as a vital buffer against global warming.

Storing energy in batteries is an increasingly important aspect of the modern world. Electric cars and giant battery banks for electric utilities require high-capacity batteries. The majority of these batteries are lithium-ion batteries that come in a number of different varieties based on the other elements used to make them.

The final agreement produced at the COP30 meeting where representatives of nearly 200 countries met to address the issue of climate change makes no mention of transitioning away from fossil fuels.

In 2015, a report by the UN's Intergovernmental Panel on Climate Change estimated that the world was headed towards 3.7 to 4.8 degrees Celsius of warming if stronger actions were not taken to cut emissions. This level of increased temperature (as much as nearly 9 degrees Fahrenheit) was described as being incompatible with an organized, equitable, and civilized global community. In short, the consequences would be dire.

Antarctica is warming roughly twice as fast as the rest of the planet, putting its vast ice sheets, surrounding oceans, and unique ecosystems at growing risk. A new study led by researchers from the Australian National University and the University of New South Wales warns that the continent may face sudden and potentially irreversible changes. Without sharp global reductions in carbon emissions, these shifts could reverberate far beyond Antarctica, affecting ocean currents, weather patterns, and coastal communities across Australia and around the world.

Researchers at the King Abdullah University of Science and Technology in Saudi Arabia have found that there are marine bacteria living in all the world’s oceans that are able to consume and digest plastic – in particular polyethylene terephthalate (or PET) plastic – the plastic found in soda bottles, clothing, and many other things.

Crops that sustain communities and economies around the world are increasingly at risk from a changing climate. Rising temperatures and extreme weather are putting everything from staple grains and fruits to specialty crops at risk, including three global favorites: coffee, chocolate, and wine grapes. According to a new study by researchers at Colorado State University, even bold climate intervention efforts may not be enough to protect them.

There has much coverage of the plight of sunflower sea stars, the large starfishes with 16 to 24 arms that inhabit the Pacific Coast of North America. A wasting disease that hit the population starting in 2013 killed off more than 90% of the population from Mexico to Alaska. Only recently has the underlying cause of the disease been identified: a specific bacterium of the Vibrio genus. But sunflower sea stars aren’t the only species that have fallen victim to the wasting disease. In fact, it has killed billions of sea stars in up to 20 species.

Texas and oil have been an inexorable combination for well over a century. The oil and gas industry is the state’s largest economic engine, generating billions of dollars and supporting hundreds of thousands of jobs. But these days, Texas is meeting much of its rising electricity demand with renewable energy.
