The largest solar storm since 2005 swept across the planet this week, forcing airlines to reroute flights and disrupting communications from global positioning satellites. This spontaneous blast of solar radiation may have affected power grids and high-frequency radio communications in the northern latitudes, said the U.S. Space Weather Prediction Center. A number of airlines, which route some U.S.-Asia flights over […]

Ahhh — to remember the glory days before dirty air descended on Delhi, a methane leak in California gassed thousands, and catastrophic smog in China prompted people to buy bottled air, of all things. Before the Industrial Revolution, the world was basically one big, serene Walden Pond, right? Wrong. Take off those rose-tinted glasses and get acquainted with the story of […]

Winter in Antarctica, it is dark all of the time. In the Antarctic summer, (between January and March, when there is plenty of daylight—twenty-four hours a day! In September, the Sun rises, and then doesn’t set again until March. Why does Antarctica have six whole months of darkness in the winter and six whole months of lightness in the summer? […]

Sophrony Kirilov pulls hard on the strings of the heavy Russian bells from inside the world’s southernmost Eastern Orthodox church, calling to Mass anybody wanting to pray on this remote Antarctic island. The 38-year-old Russian priest is clad in a loose black robe and a vest dotted with patches of penguins and seals, marking his four years of service […]

Heatwaves that used to arrive once every 20 years or so could become annual events by 2075 across almost two-thirds of the planet’s land surface – if humans go on burning ever more fossil fuels and releasing ever more greenhouse gases. Claudia Tebaldi, visiting scientist at the US National Center for Atmospheric Research, and Michael Wehner, senior staff scientist at […]

One of the most common arguments of those skeptical of global warming is that the Medieval Warm Period (800-1400 AD) was as warm as or warmer than today. Using this as proof to say that we cannot be the cause of current global warming is a faulty notion based upon rhetoric rather than science. So what are the holes in […]

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 […]

Geologists are convinced that humans have left a mark upon the planet that will detectable millions of years from now. Long after human civilization has perished, there could be a stratum of fossilized rock and a geological time zone that says: “We were here.” So there is a case for calling the present epoch “the Anthropocene” − probably dating from […]

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 […]
