Livestock was the main contributor to nitrogen emissions, along with synthetic fertilisers, land-use change and manure emissions Humans currently add around 150 teragrammes (Tg) of reactive nitrogen to the Earth’s land surface each year through agriculture and industry. This amount is more than double the pre-industrial rate, according to a new report. Climate change could contribute …

Climate change — particularly whiplash between two wet winters followed by a bone-dry, unusually hot spring, summer and fall — set the stage for Los Angeles’ deadly and devastating fires, scientists say. Why it matters: Whatever the source, it’s clear a changing climate made the fires more ferocious, long-lasting and destructive, as has been the trend across the West …

The water cycle is crucial as it not only enables the availability of water for all living organisms but also regulates weather patterns on the Earth Climate change has been “wreaking havoc” on Earth’s water cycle by disrupting how water circulates between the ground, oceans and atmosphere, according to a new report. This has led …

On February 2, 1887, residents of Punxsutawney, Pennsylvania, consulted a large rodent regarding the arrival of spring, marking the first official celebration of Groundhog Day. According to Rob Guralnick, curator of biodiversity informatics at the Florida Museum of Natural History, our ability to predict the timing of seasons hasn’t improved much since then. “We can’t …
