On Monday morning, several shows on CNN and MSNBC picked up on a United Nations report alleging that the world only has about 10 years to reduce carbon dioxide levels in the atmosphere to stave off "dire" and "catastrophic" consequences of global warming.

At 2:00 a.m. Eastern, CNN Newsroom host George Howell intoned: "A dire warning about our home, planet Earth. Experts say our planet only has a few years before the effects of climate change become obvious and even obvious to the doubters."

A bit later, he was joined by CNN meteorologist Ivan Cabrera to discuse the issue for a couple of minutes, and again about an hour later.

CNN's Early Start ran three briefs touting the "dire warning" by the U.N. and, after noting that dramatic actions are reommended, recalled that the Trump administration "rolled back Obama-era climate measures." And New Day followed up with two briefs on the subject, and fill-in host Erica Hill noted that the Trump administration "pulled out of the Paris climate accord."

At 10:44 a.m. Eastern, CNN Newsroom host Poppy Harlow devoted a segment of almost four minutes to discussing the report and its warning of "catastrophic" consequences of inaction.

On MSNBC Live, fill-in host Ayman Mohyeldin highlighted the warning of "dire consequences" and then devoted more than four minutes to discussing the issue in which he fretted that the Trump administration is "actively rolling back protections that were already in place."

And on Andrea Mitchell Reports, host Mitchell discussed the issue with correspondent Anne Thompson who warned that "time's up" and that "something has to be done to reduce carbon dioxide emissions."
