TEDx Talks· 2025-09-22 17:01
[Music] I've got to say I feel quite self-conscious about standing here today. And that's because what I'm about to share with you is something that none of you want to hear. About three years ago, I was hit with a brutal, brutal truth. that we were no longer going to make it. Those climate deadlines, we were missing them.

Is science an exclusive club? | Dr. Lucia Perez-Diaz | TEDxUNINA Federico II
TEDx Talks· 2025-09-15 16:25
Main Argument - Science often feels inaccessible due to poor communication from scientists and an overwhelming amount of information [1][2][3][9][10] - The key to understanding science is to find its relevance to everyday life and to ask questions [2][7][14][15][17] - Scientists need to improve their communication by sharing the stories and purposes behind their work, not just the data [3][23][24] - Non-scientists can help by asking questions, engaging with the material, and challenging explanations that don't make sense [24][25] Examples & Illustrations - Cooking is presented as an example of everyday science involving observation, testing, and learning [1][2] - Plate tectonics is used as an example of an abstract scientific concept that is relevant to everyday life, such as the formation of oceans, mountains, earthquakes, and volcanoes [4][5][6][8] - Climate change is used as an example of a complex scientific issue with conflicting information, where the "climate stripes" are presented as an intuitive way to understand the issue [10][11] - Scientists drilling into ancient ice in Antarctica are seeking air bubbles that are "time capsules" of Earth's atmosphere from a million years ago [16][19] Call to Action - Scientists should build "bigger doors" to make science more accessible and inspiring [22] - Non-scientists should embrace curiosity, ask questions, and challenge scientists to improve their communication [21][24][25]

But burning things for energy is creating a crisis.We must urgently reduce emissions to avert climate change. Yet, our energy demand is rising. I know what you're thinking.We're screwed. But the answer is closer than you think. B ...
