The host of PBS’s “NOVA ScienceNOW” series, most of Tyson’s tweets are about space, but he’s also been known to tweet about wine and ballroom dancing.

CHANGE: Maybe it’s a more convenient truth
“Cool It” DVD, Lionsgate

Bjorn Lomborg’s climate change documentary “Cool It” is being pitched as a calming antidote to Al Gore’s 2006 “An Inconvenient Truth.” Certainly the movie won’t leave viewers in a state of hysteria — maybe a little bored in the cap-and-trade and alternative energy parts, though. Lomborg, a former blogger on The Post’s Planet Panel, believes that global warming is a real phenomenon but argues that “fear has been ruling the climate debate” and therefore we’re not employing smart tactics to solve it. The most interesting parts are about Lomborg himself, a 46-year-old Dane who calls his mother every day and whose 2001 book “The Skeptical Environmentalist” was so controversial that the Danish government investigated (and acquitted) him on charges including “scientific dishonesty.”
