Restoring balance and harmony: A paradigm shift
If we were to describe the underlying message that we seek to express at the Optimist Daily it would be that we live in a “we-world” not in a “me-world." We recognize and respect the many challenges facing our society, yet too often “doom and gloom” stories are the only kind of news we Read More...
System to capture astronaut exhalations inspires Earth-based CO2 removal
When astronauts aboard the International Space Station (ISS) exhale carbon dioxide (CO2), it's removed from the air and pumped into space. Could an Earth-based version help remove greenhouse gas emissions from our atmosphere? In order to limit global warming to Read More...
Your future smartphone could fix its broken screen by pulling carbon from the air
Carbon-fixing materials — substances powered by the sun that use atmospheric carbon dioxide to grow and repair themselves, just as plants do — don’t yet exist outside the lab. But scientists are getting tantalizingly close to making them a commercial Read More...
Electric ferries represent the first step in sustainable maritime transportation
Since ferries take the same route again and again, they will be first mode of maritime transportation to be electrified. In Canada, two electric ferries equipped with a battery pack system are already getting to work. The electric vessels, which originally ran on diesel, are expected to reduce Read More...
Why forests are the best 'technology' to stop climate change
The warning from the world's top climate scientists that carbon dioxide (CO2) will need to be removed from the atmosphere to limit global warming to 1.5 degrees Celsius is both a due and dire recognition of the great task in front of Read More...
Bionic leaf is 10 times better at photosynthesis than real plants
Plants take in carbon dioxide, water, and sunshine to create a sugary fuel. Now researchers have done the same, but even Read More...
Companies are already capturing CO2 and turning it into something good
New companies are capturing CO2 from the atmosphere and are putting it to good use. A couple of factories in Italy and Canada are sucking carbon dioxide out of the atmosphere and turning it into carbon-neutral fuel. These technologies could make ground for a “new carbon economy” where captured Read More...
Reduction is no longer enough: Welcome to the new age of carbon removal
Reducing carbon dioxide emissions isn’t enough. The stark report in early October by the Intergovernmental Panel on Climate Change, exhorting companies and countries to move quickly to throttle global warming, is fueling heightened interest in high-tech and low-tech solutions for sucking the Read More...
Innovative material regenerates itself by absorbing carbon dioxide from the air
Scientists at MIT have developed a pioneering material that absorbs carbon dioxide from the air and uses it to restore itself. The material, which undergoes a chemical reaction similar to the process of photosynthesis in plants, could be used to make pavement that heals Read More...
Fewer biofuels, more green space: climate action researcher calls for urgent shift
Growing and harvesting bioenergy crops—corn for ethanol or trees to fuel power plants, for example—is a poor use of land, which is a precious resource in the fight against climate change, says a University of Michigan researcher. Untampered green areas like forests and grasslands naturally Read More...
