Trees That Live Fast, Die Young, and Mess with Climate Models

Under a business-as-usual scenario of greenhouse gas emissions, the average global temperature may increase by almost 5°C through the end of the century. This climate change could cause a 1-meter increase in sea levels, possibly wreaking havoc on coastal regions and demanding hundreds of billions of dollars every year in adaptation and mitigation […]

How do stars die? | Live Science

Stars begin their lives when hydrogen fusion ignites in their dense, hot cores. Once that process starts, it’s game on. The gravitational pull of all the mass of the star tries to squeeze it down into a tiny point, but the energy released by fusion pushes outward, creating a delicate balance that can persist for […]

What is renewable energy? | Live Science

Renewable energy comes from sources that are replenished naturally, such as the sun and wind. Traditional energy sources, like coal and oil, are finite and when burned, release carbon in the form of carbon dioxide and methane — two greenhouse gases that significantly contribute to the acceleration of global climate change. Renewable energy, on the […]
