No kings.
When climate deniers argue that atmospheric CO₂ was higher in the past, it's idiotic.
Humans evolved to live in the current climate, and we built our society and infrastructure accordingly.
The atmosphere didn't have oxygen billions of years ago, and we certainly don't want to return to that.
Woahhh super cool
If you're concerned about the impending Climate.gov shutdown, I encourage you to check out this action item list put together by @altnoaaclimate.bsky.social.
Well hello @altnoaaclimate.bsky.social. Extremely glad to e-meet you. 🫡
This is extremely troubling. Climate.gov is a critical hub for scientific data and information that helps with communicating climate change science and making climate-smart decisions. We should be investing more, not scaling it back.
Call your senators, call your representatives, called your governors, call your local officials. Whoever will listen.
Donate to the ACLU and other local legal aid funds. Donate to protestor GoFundMes
The transition to authoritarianism is never abrupt. It’s often a slow and incremental but this definitely feels like a critical inflection point.
I’m begging my US followers to please do what you can to support protestors and protect the immigrants communities who honestly and truly make America great.
Sending in the national guard and now the US military is an abuse of power, a clear escalation, and an attack on our civil liberties.
Standing in solidarity with everyone protesting this week (by and large peacefully) in LA and other places for the rights and safety of Latinx communities being cruelly and methodically targeted by the ICE raids.
Leaf blowers suck but they’re an effective tool against tear gas. Pass it on.

🌿 You’ve probably heard forests help fight climate change by storing carbon—but what about underwater forests?
Learn how the underwater kelp forests that line Canada’s coastlines may offer an untapped option for natural climate solutions: news.uvic.ca/media-releas...

Could underwater kelp forests offer a natural climate solution?
New research from @baumlab.bsky.social & @jennmchenry.bsky.social offers a tentative yes, finding that Canadian kelp forests may export 40,000 - 400,000 metric tons of carbon to the deep ocean each year.

10/ Protecting & restoring kelps won’t replace forests or wetlands in national inventories.
And they’re certainly no substitute for cutting fossil fuel emissions.
But our study suggests they could play a complementary role to other climate strategies, especially given kelps' other benefits.
9/ While data gaps and uncertainties remain, our framework helps constrain the possibilities—and highlights where better monitoring, mapping, and validation is still needed.
In our study we recommended greater public investment in research to fill critical knowledge gaps.
8/ We also found significant differences in kelp standing stocks and productivity across coasts and kelp species.
Although Canada’s Pacific kelp forests really stand out, even lower-productivity Atlantic and Arctic kelp beds showed some potential for deep ocean export which is promising!
7/ In its first application to Canada, we found that between 40,000 to 400,000 metric tons of kelp carbon is being exported annually to deep ocean sinks.
That’s on par with carbon burial in better-known sinks in Canada like its peatlands, saltmarshes, and wetlands.
6/ We developed a blueprint for producing first-order estimates from the limited the datasets available.
Our approach combined:
🗺️ Kelp extent maps & estimates
📈 Biomass & kelp productivity data
🌊 Coastal transport and export estimates 📉A bayesian statistical framework
5/ To address this, we assembled a team of 20+ scientists from 14 institutions under the Blue Carbon Canada program (www.BlueCarbonCanada.ca). Led by the Baum Lab (@baumlab.bsky.social) at UVic (@uvic.ca) and supported with funding from DFO, NSERCC, and OceansNorth.
4/ If we can enhance these processes through effective management, conservation, and restoration, we could one day count these actions towards national climate mitigation efforts.
But so far, few countries have had the data to reliably estimate these pathways at national scales.
3/ Kelps can contribute to long-term carbon sequestration in the ocean through three main pathways:
1️⃣ Transport of kelp fronds & detritus to the deep ocean
2️⃣ Burial of kelp detritus in continental shelf sediments
3️⃣ Export as refractory dissolved organic carbon
