More time for decarbonization: 125 aircraft could cool polar regions

With comparatively limited geoengineering, the polar regions could be cooled and climate change slowed down, say US researchers. 125 military tanker aircraft are to be used (Image: US Air Force) A Yale University researcher suggests reflecting the sun off the Earth's poles off microscopic particles and slowing global warming. This is reported by Sky News from Great … Continue reading More time for decarbonization: 125 aircraft could cool polar regions

Global warming: Japan is fighting heat death with low and high tech

Heat waves are an issue everywhere. Japan's government now wants to reduce heat deaths to zero. At the same time, companies sense new business. (Image: Dmitry Rukhlenko / Shutterstock.com) An unprecedented heat wave in June not only made Tokyo's power producer Tepco sweat. Nine extremely hot days in a row – with maximum temperatures above 35 degrees Celsius … Continue reading Global warming: Japan is fighting heat death with low and high tech

Microplastics as a raw material for artificial photosynthesis

A Korean-Dutch research group has developed a process to produce valuable chemicals from microplastics. They mimic photosynthesis. Plastic weathers over time - and accumulates as microplastics in the environment. A research group led by Chan Beum Park from the Korea Advanced Institute of Science and Technology has succeeded in combining two promising future technologies in one … Continue reading Microplastics as a raw material for artificial photosynthesis
