The joint U.S.-European Sentinel-6 Michael Freilich is the next in a line of Earth-observing satellites that will collect the most accurate data yet on sea level and how it changes over time. With millimeter-scale precision, data from this mission will allow scientists to precisely measure sea surface height […]
‘We can say that it might be associated with life,’ says researcher. Or, maybe it’s strange chemistry. Astronomers have detected a chemical signature in the atmosphere of Venus that may be associated with life. While the signature isn’t robust enough to definitively declare that there’s life on our […]
Using aircraft data, scientists have been able to understand the bigger picture on ozone levels. Their new research shows that the pollution levels in the lower part of the Earth’s atmosphere have increased over the last two decades. Called tropospheric ozone, this greenhouse gas and air pollutant can […]
At Dalhousie University, Lindy Weilgart has been studying underwater noise for 25 years. Given all the stressors on the ocean, from pollution to absorbing most of the carbon dioxide we’re putting in the atmosphere, we no longer have the luxury of not being precautionary, she says. Temperatures are […]
The Earth is running out of wilderness, as farmland and city landscapes are increasing. Humans use about 40% of the land on Earth for farmland. Land on Earth in this case includes Antarctica and the far north. In fact, most of the land that hasn’t been farmed is […]
