Latest Satellite temperature measurements Stories
Human influences have directly impacted the latitude/altitude pattern of atmospheric temperature.
Scientists at NASA report that 2012 was the ninth warmest year on record since 1880. This continues a long-term global trend of rising temperatures.
One popular climate record that shows a slower atmospheric warming trend than other studies contains a data calibration problem, and when the problem is corrected the results fall in line with other records and climate models.
In order to separate human-caused global warming from the "noise" of purely natural climate fluctuations, temperature records must be at least 17 years long, according to climate scientists.
A nagging difference in temperature readings that had raised questions about global warming has been resolved, a panel of scientists reported Tuesday.
For the first time, new climate observations and computer models provide a consistent picture of recent warming of the tropical atmosphere.
WASHINGTON (Reuters) - A dispute over whether global warming is really happening may have been caused by the placement of sensors on weather balloons when studies were done in the 1970s, researchers said on Thursday.
