It seems like something out of a science fiction movie, but a nearly silent train that glides along its tracks emitting nothing but water is a reality. In March, Germany conducted successful tests of the world’s first “Hydrail,” which is a hydrogen-powered, zero-emission train.
There has been much news recently about the growing bleaching events going on in the world’s coral reefs associated with ocean warming and acidification. The massive damage to Australia’s Great Barrier Reef is an ongoing tragedy.
Researchers at the Technion-Israel Institute of Technology have developed a new method for producing hydrogen from water using solar energy. If successfully developed, their approach would make it possible to produce hydrogen in a centralized manner at the point of sale such as at a fueling station for hydrogen-powered cars.
When we think of global climate change, what comes to mind? Rising seas? Melting glaciers? Shrinking sea ice? How about diminishing ocean oxygen levels?
According to a recent study published in the journal Global Change Biology, rising CO2 levels in the ocean can disrupt the sensory systems of fish and can even make them swim toward predators and ignore the sounds that normally deter them from risky habitats.
These days, many of the foods we buy, such as meat, bread, cheese and snacks – come wrapped in plastic. We end up with lots of non-recyclable, non-biodegradable waste. And thin plastic films are not even that great at preserving food because oxygen still gets through them.
Why should you care whether there are trees on your street or on the streets nearby? Besides the obvious fact that they make streets more attractive, street trees provide a number of real benefits both for residents and for the environment.
Should we really be putting food scraps down our sinks? Advertisements for kitchen garbage disposals assure us that these devices are a ‘hygienic way of eliminating waste and keeping odors at bay’ – but behind marketing materials questions remain.
The effects of climate change are being felt around the world, including in some well-known places in the Northeast. Buzzards Bay is a popular destination for fishing, boating, and tourism adjacent to Cape Cod in Massachusetts.
Snow season is here. The chances are good you’ll find yourself behind a truck spreading salt on the roads in an attempt to deice them. You may even try a little salt on your own front porch. Annually we spread about 20 million tons of road salt in the U.S., and we’ve been doing it since the late 1930s.
