Truth over opinion. Climate politics and economy (failing alternative to science & policy). Hope can only help when we realize that there are viable alternatives to our political/economic dystopia.

As someone who often conducts fieldwork in remote places, I find it really irritating that many basic applications now require an internet connection to function.

You probably heard the US admin is threatening to break up the National Center for Atmospheric Research: but did you know they already froze funding for the 9 regional Climate Science Adaptation Centers? From tracking invasives to helping tribes with drought, here's why the CASCs matter ⬇️
From invasive species tracking to water security – what’s lost with federal funding cuts at US Climate Adaptation Science Centers
The people who manage America’s aquifers, wetlands, shorelines and recreation areas rely on federal science as they face new and rising risks in a changing climate.

#quickFix thinking, triggering “good camp vs. bad camp thinking” is the result of #fear. It prevents clear #thinking and while we’re under it’s influence we are unable to #solve it. We can only - #collectively - change our #society, so #hope & #trust can reappear! Let’s start now!

I’m increasingly convinced that self care is climate action. After all, if we want a sustainable world, don’t we have to be sustainable too?
For me, that means time with friends & fam, nature, knitting, chocolate, tea, and a stack of good books.

For years I’ve dealt with some of the nasty comments & emails I receive by writing completely unfiltered replies, telling the sender exactly what I think of them and their comment—then deleting them. Never sending.

About 90% of CO₂ removal (CDR) credits were bought by Microsoft in 2025. People have different ideas about how to scale CDR, but I don't think CDR will ever go anywhere unless the R&D is funded and led by governments.

For me the answer is neither. Let's get out of fossil fuels fast enough to minimise both of these very real risks.
