Watch today's "We the Geeks" at 2:00 p.m. ET right here, or on the White House Google+ page.

Here at the White House, while we’re beginning to thaw from this week’s bone-chilling deep freeze, our discussions about the science of weather extremes are heating up.

We know that no single weather episode proves or disproves climate change. Climate refers to the patterns observed in the weather over time and space – in terms of averages, variations, and probabilities. But we also know that this week’s cold spell is of a type there’s reason to believe may become more frequent in a world that’s getting warmer, on average, because of greenhouse-gas pollution.

Join us this Friday, January 10th at 2:00 p.m. ET for We the Geeks: "Polar Vortex" and Extreme Weather, for a conversation with leading meteorologists, climate scientists, and weather experts about why temperatures dipped to such frigid lows this week, how weather experts turn raw data into useful forecasts, and what we know about extreme weather events in the context of a changing climate.

Cristin Dorgelo and resident polar-science expert Brendan Kelly from the White House Office of Science and Technology Policy will moderate the live discussion, to include:

We hope you’ll join us this Friday at 2:00 p.m. ET at WhiteHouse.gov/We-The-Geeks and on the White House Google+ page to hear from the experts on the front lines of weather forecasting and climate science.
