The film "Arctic Emergency: Scientists Speak On Melting Ice and Global Impacts" by Max Wilbert features climate scientists discussing the critical state of the Arctic in their own words.

Rising Arctic temperatures are causing sea ice to melt and permafrost to thaw, destabilizing a system vital to global climate, often called "Earth's Air Conditioner." This directly contributes to global warming, impacting weather patterns, natural systems, and human life worldwide, with the Arctic at the center of these profound changes.

Published on August 1, 2014, the film includes insights from leading experts such as Jennifer Francis (Rutgers University), Ron Prinn (MIT), Natalia Shakhova (University of Alaska-Fairbanks), Kevin Schaefer (National Snow and Ice Data Center), and others from prominent research institutions.

Alejandro Aravena's architectural philosophy is to "bring the community into the process." Ten years ago, when tasked with building housing for 100 families in Chile, he found inspiration in favelas. Instead of small units in large buildings, he designed flexible "half-homes" that each family could expand. This complex problem found a simple solution through direct collaboration with the families themselves.

Aravena showcases three projects where clever rethinking led to beautiful, beneficial design. Learn more at Alejandro Aravena's website, or follow TED on Twitter and Facebook.

A 60-second animation by the Royal Society and the US National Academy of Sciences explains climate science.

Over the last 200 years, human activities, primarily fossil fuel burning, have increased atmospheric CO2 by 40%. If unchecked, these emissions could warm the planet by 2.6°C to 4.8°C this century, posing serious threats to societies and nature.

Award-winning economist Paul Collier explores how to reconcile economic growth with environmental sustainability. He argues against "plunder," where a few exploit many, taking resources that belong to future generations. Our obligation to the future is a fundamental principle.

His book, "The Plundered Planet," delves deeper into these ideas. Purchase it on Amazon or at your local bookstore. This content was produced by the RSA (Royal Society for the encouragement of Arts, Manufactures & Commerce).
