SciShow explains why our nights are getting hotter and how that disrupts our sleep

I have another post about climate change featuring two recent videos from SciShow after yesterday's DW Planet A and SciShow address the environmental costs of cryptocurrencies. I begin with the more recent and more general, Why Our Nights Are Getting Hot.

The average global temperature is on the rise, evidenced by the ten warmest years on record happening since 2005. But this isn’t just about greenhouse gases preventing heat from escaping. Another culprit comes in the form of…clouds.
That's a good explanation of how nights can and sometimes do warm up faster than days. It also serves to illustrate that climate change results from changes in the average of all temperature readings over time, not just the daily high temperature. SciShow also covered what this means to people in last week's Can’t Sleep? Blame the Climate Crisis.

Today, we bring you two surprising effects of the climate crisis: less sleep and more dying trees.
I wrote Lancet reports climate change is a 'medical emergency' nearly four years ago and I don't recall sleep disorders being one of the effects mentioned, but that doesn't mean they aren't important. As Hank Green explained, losing sleep results in other health issues, showing that everything is connected to everything else and there is no free lunch. It also means that if someone says they are losing sleep over climate change, they could mean it literally.
