COP28 Climate Conference Ends | Why Are Some People Affected By Seasonal Affective Disorder?

Climate Conference Ends, With Few Immediate Results

The United Nations climate conference, COP28, ended this week in Dubai. After a lot of arguing over wording, the final agreement from the meeting calls for “transitioning away from fossil fuels in energy systems, in a just, orderly and equitable manner, accelerating action in this critical decade, so as to achieve net zero by 2050 in keeping with the science.” That text is significant in that it is the first time, surprisingly, that fossil fuel use was mentioned by name in a COP agreement. However, many critics of the proceedings point out that even this recognition is too little, too late, with few practical routes to keep global warming under thresholds considered to be catastrophic.

Casey Crownhart, climate reporter at MIT Technology Review, joins Ira to walk through the results of COP28. They also discuss other stories from the week in science, including research into morning sickness, clusters of brain cells that appear to do speech recognition tasks, a first look at asteroid samples from the OSIRIS-REx mission, and the tale of an unusual frog that camouflages itself as poop.

Why Are Some People Affected By Seasonal Affective Disorder?

As the shortest day of the year approaches, many people might notice their energy levels starting to dip. For some, winter is an especially challenging season. About 5% of adults in the United States experience seasonal affective disorder, also known as SAD.

Ira talks with Dr. Kathryn Roecklein, associate professor of psychology at the University of Pittsburgh, about her research into what makes some people more susceptible to seasonal depression than others, and the most effective treatment options.

Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
