Scientists have recorded that the temperature of the oceans has been on the rise. The temperatures have been rising at a rate of 40% on average over what they previously predicted over the past five years. The year 2018 was warmer than the previous year and it’s still getting warmer. Heating of the ocean plays a big role in climate […]

Scientists have found telltale evidence that an asteroid twice as large as any previously known smashed into Earth about 300 million years ago. Previously, the largest asteroid impact was believed to have occurred 66 million years ago, when a massive space rock hit what is now the Yucatan Peninsula in Mexico, causing such havoc that it led to the extinction […]

More than 850 million people around the world—one in nearly seven—don’t have enough to eat. Although current global food production is sufficient to feed everyone, the number eating less than the minimum the human body needs—an average 2,100 calories a day for adults—now grows by more than ten million a year, mostly in the poorest nations. Countries with unstable food […]

“It has happened,” said Philip Bump. For the first time in human history, atmospheric carbon dioxide levels hit a daily average of 400 parts per million (ppm) last week. “There is now more carbon dioxide in the atmosphere than at any point since 3 million years ago.” Back then, global temperatures were about 7 degrees higher, the Arctic was ice-free, […]

It’s been five years since the Deepwater Horizon oil rig exploded in the Gulf of Mexico, killing 11 and releasing a torrent of petroleum into the sea. But despite a massive, multibillion-dollar cleanup effort, the effects of the largest marine oil spill in U.S. history may linger for decades. BP (British Petroleum), which operated the rig, has already paid […]

Soil frost is a nearly universal process in the Arctic. In a recent dissertation by doctoral student Marina Becher at Umeå University, it is shown that the frequency and extent of Arctic soil frost is important for the release of the greenhouse gas carbon dioxide from arctic soil. Soil in the Arctic has for thousands of years gathered large quantities […]

Stanford scientists have found that chronically low levels of oxygen throughout the oceans hampered the recovery of life after the Permian-Triassic extinction, the most catastrophic die-off in our planet’s history. Also known as the “Great Dying,” global ecosystems collapsed as some 90 percent of species perished in this extinction event 250 million years ago. The new findings, published this week […]

The temporary housing settlements of Williston, N.D., might seem like an unlikely haunt for archaeologists. Nonetheless, a team of “punk archaeologists” are there, finding the history in the present by peering into the lives of people at the heart of North Dakota’s oil industry. Thanks to the lucrative nature of the “Bakken boom” — the ongoing oil drilling in North […]

Breathalyzers could be used to curb alcohol abuse among scientists at US bases in Antarctica following “unpredictable behavior” caused by excess drinking, including fights and indecent exposure. Officials from the National Science Foundation told an audit of healthy and safety at the two US-run bases — McMurdo Station and the South Pole — that drinking has led to “unpredictable behavior […]

The ozone layer is a protector of the earth from ultraviolet radiation from the sun. According to reports the ozone layer is getting smaller over Antarctica. The scientists are using satellites and sensors to get information on the measurements of the ozone layer. Since the early 20th century when the emissions of chemical substances called halo-carbons the ozone layer has […]
