Things are less than ideal right now. Here are some climate-themed valentines to, at least, maybe put a slight smile on your face.

You can't... repeal... a scientific finding. At that point it's just called lying about it.
Breaking News: The Trump administration repealed the bedrock scientific finding that greenhouse gases threaten human life and well being, meaning that the EPA can no longer regulate them. nyti.ms/4rSszQu

I love writing about geeky science that has real-world implications. In this case, a new NOAA index does a more solid job of classifying El Niño and La Niña—and that helps explain some recent puzzling events. @climateconnections.bsky.social

The extreme cold across eastern N America is due to the Alaskan Ridge regime, which on average brings the coldest winter weather to this region.
Is this happening more often?
No. During the modern warming era, there has been no observed trend in the occurrence of this regime at this time of year.

“Survey after survey has shown that business owners overestimate how many customers drive to their stores vs walking or biking. In a 2012 Los Angeles study, more than half of the store owners on the bike-laned part of the boulevard thought most of their customers drove. The actual number was 15%.”
I read all the studies on the economic impact of bike lanes. Here's what I learned.
Research proves that bike lanes are good for business. So why do so many stores and restaurants still oppose them?

Climate change isn't the sole culprit of this holiday heat, but it did make it much more likely than past generations would have experienced.
Climate Shift Index shows human-caused climate change made this widespread warmth far more likely -- and in some areas, nearly impossible without it.
