Right now on Low Plaza, Green Umbrella is holding “350 – Day of International Climate Action at Columbia University,” with appearances and tabling by many other campus student groups. More importantly, though, there’s free food! The organizers tell Bwog food will be in evidence until the event ends at 6.

In other humanitarian news, Kappa Phi Lambda is hosting a dinner supporting victims of domestic violence in Roone at 7 p.m. While tickets are $10, all the proceeds are being donated to Becky’s Fund, “a non-profit organization devoted to ending domestic violence through support and education.” Oh, and the ticket’s good value itself, including “dinner, show, 2 raffle tickets, and free entry to our afterparty.”

Finally, if you can’t wait for This Is It to get your Michael Jackson fix, Columbia University Dance Marathon is offering a free “Thriller dance” class at 7:30 in Aerobics Room 4 of Dodge, ending with (unofficially) participating in the latest attempt to break the world simultaneous-dance record.
