June was the 8th warmest month on record, across the globe last month.

Global warming, caused by the greenhouse effect, produced the 7th warmest June on record on a global scale.  As in any month, there were areas with cooler than normal temperatures, but on a world wide scale it was yet another warm month.  Weather and climate should not be confused.  We need to continue to study temperature trends over many years and over a wide global scale to determine what effects are occurring from greenhouse gases.  If your backyard is chilly, that does not mean global warming is bunk.
