Overshoot reshapes climate strategies—but the path to net zero remains unchanged
Temporary overshoot of global temperature targets—particularly the 1.5°C goal of the Paris Agreement—is no longer just a modeling concept. New research, published in Nature Climate Change and led by the Euro-Mediterranean Center for Climate Change (CMCC) in collaboration with
Why being nice matters in a complex world
Coan says practicing kindness, be it big or small, is a one-two punch for your health and for those around you. That includes "weak ties," the casual, micro-relationships people form. "People often deride small talk as shallow," he said. "Well, it's not. Small talk and weak
Salt may have pushed us further into Snowball Earth 700 million years ago
Our planet plunged into one of the most dramatic climate states in its long history, approximately 720–635 million years ago. During a period geologists call Snowball Earth, ice sheets crept from the poles all the way to the tropics, covering the oceans and continents in a
