Did you know that the sound from a heavy truck moving down the road – approximately 85dB (decibel) – can have an adverse effect on your health? It isn’t just rock musicians who suffer from hearing loss due to exposure to loud noises – noise pollution can cause a host of ailments, from tinnitus to depression. Exposure to sounds as …
If a new scientific paper is proven accurate, the international target of limiting global temperatures to a 2°C rise this century will not be nearly enough to prevent catastrophic melting of ice sheets that would raise sea levels much higher and much faster than previously thought possible. “Parts of [our coastal cities] would still be sticking above the water, but …
Gun the engine, and the ignition of fossil fuel produces not just working energy but heat that dissipates quickly into the atmosphere. But it also produces carbon dioxide that dissipates into the atmosphere. And in less than two months, according to new research, that pulse of carbon dioxide will have engendered more heat for the planet than the original touch …
The rapidly rising levels of carbon dioxide in the atmosphere affect plants’ absorption of nitrogen, which is the nutrient that restricts crop growth in most terrestrial ecosystems. Researchers at the University of Gothenburg have now revealed that the concentration of nitrogen in plants’ tissue is lower in air with high levels of carbon dioxide, regardless of whether or not the …
Last week’s piece drew responses that throw into relief how much the language we use depends on our most basic assumptions about how the world works. If left unexamined, that language leads to further conclusions that go unchallenged because the underlying assumptions are never scrutinized. I challenged the Breakthrough Institute’s notion that humans are in one category and nature in another. If one …
What if there were a risk-free way of helping to mitigate climate change while simultaneously addressing food and water security? A new report from the Center for Food Safety’s Cool Foods Campaign says that such an opportunity is possible, and it’s right below our feet. Soil & Carbon: Soil Solutions to Climate Problems outlines how it is possible to take atmospheric …
The gases used to knock out surgery patients are accumulating in the Earth’s atmosphere, where they make a small contribution to climate change, report scientists who have detected the compounds as far afield as Antarctica. Over the past decade, concentrations of the anesthetics desflurane, isoflurane and sevoflurane have been rising globally, the new study finds. Like the well-known climate warmer …
Scientists warn that our fate is in our own hands as humans now control almost every aspect of the planet, on a scale akin to the great forces of nature. Nature has been replaced by humans as the driving force behind changes on the planet − and we need to take urgent action if we are to avoid our own …
The human-dominated geological epoch known as the Anthropocene probably began around the year 1610, with an unusual drop in atmospheric carbon dioxide and the irreversible exchange of species between the New and Old Worlds, according to new research published in Nature. Previous epochs began and ended due to factors including meteorite strikes, sustained volcanic eruptions and the shifting of the …
Trees are like our planet’s lungs. Every second of every day, they’re absorbing CO2 from the atmosphere, and converting it into energy. In fact, according to a study by researchers at NASA, each year, tropical rainforests absorb a staggering 1.4 billion metric tons of CO2 from Earth’s atmosphere. Through the process of photosynthesis, they’re “inhaling” that CO2, and keeping it …
