Global Climate Change = The Weather

Earth's climate continues to confound scientists. Following a 30-year trend of warming, global temperatures have flatlined since 2001 despite rising greenhouse gas concentrations, and a heat surplus that should have cranked up the planetary thermostat.

"The discrepancy gets to the heart of one of the toughest problems in climate science -- identifying the difference between natural variability from human-induced change"

Maybe its tough because there is no difference.
