The Nature Record Now it’s our turn to shape what comes next. A new project. A mission years in the making.

The DRAFT Nature Record national assessment has dropped and is ready for comment! I'm proud to be one of the authors. This is the first comprehensive, independent, evidence-based assessment of how nature is doing across the U.S.
Come read. Come comment. Come shape the record.

The future of Europe’s forest disturbance regimes– a thread.

Tl, dr: Disturbances from wildfire, bark beetles & wind will continue to increase in the coming decades. Under unabated climate change disturbances could more than double by 2100.

Six trillion ways to solve climate change Β» Yale Climate Connections New research shows that mixing and matching manageable climate policy 'wedges' can add up to real solutions.

A new paper on the "stabilization wedge" idea was published in the journal Science today. The authors provide 36 wedge strategies that together can be mixed and matched into more than 6 trillion combinations able to limit global warming to 1.5Β°C. @bhensonweather.bsky.social has a detailed analysis:

Feral camels searching for water descend on remote communities Large mobs of camels are wreaking havoc in remote Indigenous communities as they desperately search for water.

> $300 billion for AUKUS, but remote communities are still having to put up with this dangerous mess, as government funding is inadequate to resolve the issue. Probably wouldn't be tolerated if it were happening in Canberra, would it, @albomp.bsky.social?

MN protestors #protip put 2 Idaho Russets in the oven at 420 degrees for 45 min, take them out and foil wrap, 1 in each pocket before you go out. Theyll stay warm for 3-4 hours even in this weather and you can eat em when you like. They used to send us kids out like this back in the 70s trust me.

"Minnesota is deeply grounded in the values of community, compassion, dignity, and solidarity. The violent actions of federal agents have had profound effects on families and communities across our city and state, creating an environment of chaos, fear, and disruption in our neighborhoods. This federal operation has made life difficult for many residents to shop for groceries, go to work, take their children to school, or keep their small businesses open. When residents are brutalized and profiled, families are torn apart, and children are arrested, our communities are not any safer. We continue to demand that ICE, and all federal agents leave our state immediately. Minnesotans have a long tradition of activism, protest, and civic engagement during significant inflection moments in our state. A broad coalition of labor organizations, faith communities, community-based organizations, students, small businesses, and workers have called for a statewide Day of Truth and Freedom as a time for solidarity, community, mutual aid, and protest. The Minneapolis City Council fully supports this action as a time to exercise your constitutional rights, to express support for our neighbors, and demand the end of this federal occupation. We acknowledge and respect the diverse ways individuals, families, essential workers, students, and businesses may choose to observe this day and support our community.
Together, with our community, the City Council reaffirms our commitment to civic expression, community safety, and our immigrant neighbors. We will continue the work of ensuring justice, freedom, and dignity for all during and beyond this occupation."
