New research indicates the impact of rising CO2 levels in the Earth’s atmosphere will cause unstoppable effects to the climate for at least the next 1000 years, causing researchers to estimate a collapse of the West Antarctic ice sheet by the year 3…

Large CO2 release speeds up ice age melting
Radiocarbon dating is used to determine the age of everything from ancient artifacts to prehistoric corals on the ocean bottom. But in a recent study appearing in the Aug. 26 edition of the journal, Nature, [...]
Galactic super-volcano in action
A galactic “super-volcano” in the massive galaxy M87 is erupting and blasting gas outwards, as witnessed by NASA’s Chandra X-ray Observatory and NSF’s Very Large Array. The cosmic volcano is being driven by a giant black hole in the galaxy’s …
New Look at Satellite Data Supports Global Warming Trend
A new analysis of satellite data collected since the late 1970s from the lowest few miles of the atmosphere indicates a global temperature rise of about one-third of a degree Fahrenheit between 1979 and 1999. The results are at odds with previous analyses that show virtually no warming in the satellite record over the 20-year period.
