A United States and Spanish research team has conducted a study into the most likely causes of climate change and came to a rather surprising conclusion. The most feasible manner of stopping climate change is halting economic growth. Or changing … Continue reading →
A large diversity of gasses in the atmosphere influence air quality, climate change and the recovery of the ozone layer. Measuring the concentrations of these gases in the atmosphere is quite straightforward. But pinpointing wether the gasses are a natural … Continue reading →
Eating is actually a big word for the marine worm Olavius algarvensis, since the worm completely lacks a digestive system. Over the course of evolution the worm has gathered millions of symbiotic bacteria that have found a home under its … Continue reading →
Environmental policy has historically been driven by a demand-side mindset — attempting to limit consumption of precious fossil fuels through pollution permits, taxation, and multi-national climate change treaties. However, new research from the Kellogg School of Management at Northwestern University suggests that actually buying coal, oil and other dirty fossil fuel deposits still in the ground could be a far better way to fight climate change.
Researchers have combined gold nanoparticles (in light red) with copper nanoparticles (in light green) to form hybrid nanoparticles (dark red), which they turned into powder (foreground) to catalyze carbon dioxide reduction (credit Zhichuan Xu)
Copper — the stuff of pennies and tea kettles — is also one of the few metals that can turn carbon dioxide into hydrocarbon fuels with relatively little energy. When fashioned into an electrode and stimulated with voltage, copper acts as a strong catalyst, setting off an electrochemical reaction with carbon dioxide that reduces the greenhouse gas to methane or methanol.
There has been much speculation about what exactly caused the end of the last ice age 10,000 years ago. Some say the Earth’s orbital changes were the cause, others say it was an increase in atmospheric CO2. But although a … Continue reading →
With atmospheric and oceanic CO2 levels rising and the consequent acidification of the oceans, marine life has to adapt rapidly if they want to stay around. Especially calcium carbonate skeleton building organisms are affected by the rapidly dwindling seawater pH … Continue reading →
