One of the things I most enjoy about Mastodon is connecting with a community that is passionate about combating the climate crisis and raising awareness about this issue that impacts us all.

Here are a few experts and organizations that I follow:

@kathhayhoe -- Chief Scientist for the global conservation organization, The Nature Conservancy

@ClimateMigration - curated posts related to climate science

@the-climate-exchange-science - community of climate scientists and experts that share news about the state of our planet

@the-brockovich-report-ErinBrockovich - The Brockovich Report by climate activist and change-maker Erin Brockovich

@climate-change-and-weather-misinformation-NewsLitProject - learn about climate misinformation from The News Literacy Project team
