Catherine Ritz is a French Antarctic researcher, best known for her work on ice sheets and their impact on sea level rise.

[1] Catherine Ritz received her master's degree Maîtrise de Physique in physics in France in 1975.

The article, based on research led by Ritz and Tamsin Edwards from The Open University, created models based on satellite data to examine the potential impact of Antarctic sea ice collapse on global sea levels.

Using more comprehensive methods than those used in previous studies,[7] the team found that the collapse of Antarctic ice sheets would have serious consequences for sea level rise (up to a half-meter by 2100 in a high-emissions scenario),[8] but that the effects likely would not be as dramatic as other high-profile studies had predicted.

Ritz also plays a prominent role in international efforts to monitor Antarctic ice and understand climate change.
