Remote Sensing Systems has just released their global satellite measured temperatures for the month of April.
Globally, the average April 2013 temperature for the lower troposphere was .219 degrees C. or .394 F. above normal, making it the 13th warmest April in the satellite record.
The latest RSS decadal temperature trend for the lower troposphere is +.130 C. per decade. (see image below).
Another cold month for the continental U.S.
For the third consecutive month, the U.S. averaged colder than normal. April 2013 was .549 degrees C. or .988 degrees F. below normal. This was also the third straight month that the U.S. temperature anomaly was at least a 1/2 degree C. or lower.
Climate model projections can become quite uncertain at more localized levels.
Arctic sea ice melt season trend this year.
Last month was the warmest of any month on record globally going back to the late 19th century.
Why hasn't global sea level rise accelerated over the past 20+ years?
Researchers recently compiled a new historical record of sea ice extent in the Arctic going back to the mid-19th century.
The annual "State of the Climate" report was just released and the results are quite sobering.
