At COP29, The World’s Top Polluters Are No-Shows | Walking Pneumonia Is Spiking

Leaders from the top-polluting countries, like the US and China, aren’t showing up to the UN’s big climate conference in Azerbaijan. And, walking pneumonia typically affects school-age kids, but the CDC reports a rise in cases in children aged 2-4.At COP29, The World’s Top Polluters Are No-ShowsThe United Nations’ annual international climate conference, COP29, got underway this week in Baku, Azerbaijan. Leaders from around the world come together at this conference to hammer out deals between nations to lower emissions and coordinate climate change-related financial efforts.And a big focus this year was to negotiate a deal for wealthier countries to financially compensate developing nations who’ve experienced climate-change related damage. The only problem is that world leaders from the top-polluting countries, like the US and China, aren’t even showing up.Ira Flatow is joined by Umair Irfan, senior correspondent at Vox, to catch up on this and other science stories of the week, including new data on rising alcohol consumption, why Voyager 2 got an inaccurate snapshot of Uranus in the 1980s, and why the world’s largest organism might also be its oldest.Walking Pneumonia Is Spiking. Here’s How To Stay SafeLast month, the Centers for Disease Control and Prevention put out a report outlining a significant spike in Mycoplasma pneumoniae infections, better known as walking pneumonia. This respiratory illness is caused by bacteria spread through respiratory droplets, and symptoms usually mimic the common cold. It’s pretty common, with about 2 million infections happening each year, mostly in school-age kids. This year’s spike, which started in the spring, is a little different: There’s been a significant increase in kids aged 2 to 4 and it is now the new leading cause of pneumonia for that group.Dr. Preeti Sharma, pediatric pulmonologist at Children’s Heath in Dallas, knows what it’s like to have a child with mycoplasma pneumonia. Her daughter came home with the illness in the spring. What she thought was a typical cold turned into a deep and lingering cough: a telltale sign of walking pneumonia.Dr. Sharma, who is also an associate professor at UT Southwestern, joins Ira Flatow to discuss this year’s Mycoplasma pneumoniae spike, the best treatments, and how to keep your family healthy this holiday season. Transcripts for each segment will be available after the show airs on sciencefriday.com.
