Northern Warming Seen in Boreholes
February 22 — Measuring temperatures inside holes in the ground accurately shows that Earth's Northern Hemisphere has warmed about 2 degrees Fahrenheit since the Industrial Revolution. The new research in Geophysical Research Letters confirms a study published lat year in Nature. (University of Utah release) More

Uneven Global Sea-Level Rise Explained
February 21 — Global climate change is having a direct impact on the Earth?s sea level and scientists have shown the sea level ?fingerprints? of polar ice sheet melting to prove it. The study in the journal Nature shows that melting from the Antarctic, for example, has a distinctly different pattern or fingerprint in how it affects sea level than melting from Greenland or small mountain glaciers. (University of Toronto release) More

Southern Ice Caps Likely to Vanish in 15 Years
February 18 — Many glaciers and ice caps atop mountains in Africa and South America will probably have melted within the next 15 years. At least one-third of the massive ice field atop Tanzania's Mount Kilimanjaro in Africa has disappeared, or melted, in the last dozen years, according to Lonnie Thompson of Ohio State University. (Ohio State University release) More

Springtime Ozone Voids Seen Above Arctic Surface
February 7 — Data gathered last spring have revealed long swaths of the lower atmosphere nearly empty of ozone over northern latitude seas. An instrument-laden research aircraft observed the ozone loss while flying at extremely low altitudes over Hudson Bay, Baffin Bay, and parts of the Arctic Ocean. (NCAR release) More

Ordinary Soot a Major Cause of Global Warming
February 7 — In their search for a solution to global warming, climatologists and policy makers have overlooked one of the leading causes of rising world temperatures: soot. According to a new study in Nature, soot may be the second biggest contributor to global warming. (Stanford University release) More
