Global warming is real say experts

US experts say satellite readings, temperature records, support each other

A team of US scientists has fired a counter volley against climate sceptics who have cited satellite temperature measurements showing a global cooling of the lower troposphere of around 0.05 degrees centigrade per decade as evidence that global warming is not occurring. The satellite measurements contradict surface air temperature readings which indicate a global annual mean warming of 0.13 degrees centigrade per decade, leading in 1995 to the warmest year on record. However, in a letter to the science journal Nature, published today, a team from the US National Center for Atmospheric Research in Boulder, Colorado, suggests that errors in measurements are incurred when readings are taken from different satellites. They conclude that taking these errors into account, the real trend in [satellite recorded] temperatures is likely to be positive, albeit small.
