“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.

What's one thing we can all do in the fight against climate change? Talk about it, as daunting as that may seem!
Because people care about climate change (and want to talk about it) more than you probably think.

These people are nuts. NCAR developed the GPS dropsonde, which revolutionized the understanding of TC structure, improved forecasts, and validated remote sensing platforms, as documented in over 400 peer-reviewed publications in the last 25 years. And that’s just one of NCAR’s countless advances.
Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

Before the 1990s, plane crashes caused by microbursts used to kill planeloads of people fairly regularly.
Dr. Ted Fujita and NCAR scientists figured out how to detect microbursts and warn pilots about them.
Since then? Zero airliner crashes from microbursts.
