JPL scientist Josh Willis, from NASA's Ask A Climate Scientist campaign, asserts that global warming is not pausing, despite some decades showing slower surface temperature increases.

Willis points to increased ocean heat trapping and continuously rising sea levels as clear evidence. See [global temperature trends](http://climate.nasa.gov/key_indicators#globalTemp) and [sea level records](http://climate.nasa.gov/key_indicators#seaLevel).

While natural fluctuations occur, human-caused climate change is undeniably progressing. Explore more NASA climate science answers [here](http://bit.ly/1b7rSdL).
