Antarctica’s ice sheet and The Landscape Below

Aerial view of rugged mountainous terrain with glacial water in between the peaks.

A groundbreaking new map offers an unprecedented glimpse beneath Antarctica’s ice sheet, revealing the continent’s hidden topography with remarkable precision. This high-resolution terrain map, known as the Reference Elevation Model of Antarctica (REMA), was released by researchers at the National Geospatial-Intelligence Agency in September 2018. The REMA provides detailed imagery down to the size of a car in some areas, […]

The Missing Heat – Global warming hits plateau

The Missing Heat - Global warming hits plateau

Global warming hits plateau. . . What does that mean for the threat of catastrophic climate change? Why has the warming trend slowed? Climatologists aren’t sure. What they do know is that the average air temperatures at the earth’s surface have risen only about 0.2 degrees Fahrenheit since 1998—the hottest year of the 20th century—even as humanity has continued to […]

Antarctic ice sheet is more vulnerable to carbon dioxide than expected

Results from a new climate reconstruction of how Antarctica’s ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought. Details appear in two […]

Megadrought may grip the Southwest

Megadrought

The Southwest and central Great Plains are likely to be hit in coming decades by the most prolonged megadrought in more than 1,000 years, a new climate study predicts. Scientists from NASA, Columbia University, and Cornell University created a long-term climate model after analyzing historical temperature records, carbon dioxide emissions, and drought trends from tree rings.The record shows that the […]

1934 is the hottest year on record

The year 1934 was a very hot year in the United States, ranking fourth behind 2012, 2006, and 1998. However, global warming takes into account temperatures over the entire planet. The U.S.’s land area accounts for only 2% of the earth’s total surface area. Despite the U.S. heat in 1934, the year was not so hot over the rest of […]
