A carcinogen isan agent with the capacity to cause cancer in humans. Carcinogens may be natural, such as aflatoxin, which is produced by a fungus and sometimes found on stored grains, or manmade, such as asbestos or tobacco smoke. Carcinogens work by interacting with a cell's DNA and induc...
Global warming is a significant increase in the Earth's climatic temperature over a relatively short period of time as a result of the activities of humans. In specific terms, an increase of 1 or more Celsius degrees in a period of one hundred to two hundred years would be considered global...
Nitrous oxide(N2O) is another important greenhouse gas. Although the amounts being released by human activities are not as great as the amounts of CO2, nitrous oxide absorbs much more energy than CO2 (about 270 times as much). For this reason, efforts to curb greenhouse gas emissions have ...
Deep learning is generating new insights into the dynamics of complex natural systems and how to identify early signals of tipping into irreversible and potentially catastrophic environmental change, such as desertification of the Amazon, melting of the Greenland ice sheet, or methane released by ...
Ultimately, what really matters isn’t the amount of greenhouse gas emissions; what matters is the higher temperatures and their impact on humans. And on that front, a gas like methane is much worse than carbon dioxide. It drives the temperature up immediately, and by quite a bit. When ...
“There is the emissions side that comes partly from fossil fuel use and partly from things like nitrous oxide and methane emissions,” she said. “The other side is looking at the soil globally as a key resource. Right now, a lot of agricultural soil is a net emitter of carbon dioxide...
Dumped tires are highly likely to catch fire, which is highly not extinguishable. The thick, dark smoke released contains toxic pollutants including carbon monoxide, benzene, xylene, acetone, ethylene, and cyanide, which spells environmental pollution and poses health risks for humans. ...
Evidence in humans for the relation between serotonin and LDAEP is inconsistent. Proitti-Cecchini et al (1997) showed that a single-dose of zolmitriptan, a 5-HT1B/1D agonist, increased the intensity dependence of auditory N1/P2 amplitudes, whereas fenfluramine decreased it. Studies with ...
Greenhouse Gas Research Centre has pointed out that New Zealand’s animal-produced methane emissions do more to warm the climate than all our carbon dioxide and nitrous oxide emissions combined. The impact of methane in the atmosphere is like compounding interest: it mounts as time goes by. ...
A carbon footprint is only one component of the broader ecological footprint. An ecological footprint compares the population's consumption of resources and land with the planet's ability to regenerate. As of 2022, humans are consuming Earth's resources at a rate 1.7 times faster than the pla...
