I will discuss the first detection of the power spectrum of CMB lensing in temperature maps made by the Atacama Cosmology Telescope. The CMB lensing power spectrum is a direct gravitational probe of dark matter and geometry at redshift ~2. I will demonstrate the power of such CMB lensing measurements by explaining how with our measurements, CMB data alone require the presence of dark energy at above 3-sigma.
