A missed Earth Day

Weeks ago, as the pandemic dragged on and protests against police violence ramped up across the region, I spoke to several Bay Area residents involved in different kinds of climate change activism. How had the pandemic affected their efforts — and how did they see multiple crises interacting with each other?

The short version: Everyone’s frustrated, especially when it comes to planned rallies and in-person education. But there’s no other choice except to adapt to virtual efforts amid a world that changed faster than even they expected.

“Some of our more disruptive actions, sit-ins, marches — they’re most visual, they make the most political change — those aren’t as safe right now,” one young activist told me. “It requires significantly more work (to think through): What are pandemic protesting tactics?”

Can we ‘see’ the pollution impact of shutdown?

Bay Area carbon dioxide levels by county before and after the shutdown.

The Bay Area saw sudden steep declines in air pollution and greenhouse gas emissions in the first weeks of the coronavirus shutdown — but did they stick?

New preliminary data from San Francisco company Aclima show air pollutants getting closer to normal levels several months into the pandemic — and big differences in which parts of the Bay Area saw air quality improve and carbon dioxide concentrations decline.

There are also very cool comparison maps showing levels of carbon dioxide change on a street-by-street basis across the first six months of the year and a short explanation on why carbon dioxide is a “tricky pollutant to understand.”

Rising bay

Before MicroClimates launched, we asked readers how the pandemic had (or hadn’t!) affected your thinking on climate change.

For those for whom it had made a difference, there was a split in how: The experience of living through a global pandemic had made some feel more pessimistic about our ability to act on climate change and others more optimistic. The changes in daily life also made an impact: One reader noted that being outside of a heavily air-conditioned office had shifted how aware they were of extreme heat.

Here’s a few of your comments:

“If the pandemic is any indication of problems humanity face, imagine the problems with a heating world and more migrants coming to the US to escape the heat, the lack of rain. If we are this divided about basic things about wearing a mask, imagine the problems we are about to face regarding water.” Gina Grandini.

“It has made me see that we can act quickly in the face of an existential threat.”Marina Psaros, co-author of the upcoming “The Atlas of Disappearing Places: Our Coasts and Oceans in the Climate Crisis.”

For next time: On top of everything else, we have an election coming up: Do you consider yourself a climate voter? I’d like to hear from some Bay Area voters who are going into this election considering global warming as one of their top issues, potentially for inclusion here in MicroClimates and also to inform our upcoming coverage of local elections.
