The latest European Grassland Butterfly Indicator is out. It shows that grassland butterflies have declined by 47% since 1991, indicating a huge loss of grassland biodiversity. The data come from 16,150 transects & 15,000 volunteers. We are calling for urgent action. www.bc-europe.eu/documents/69...

Bruce Springsteen - Streets Of Minneapolis (Official Audio) YouTube video by Bruce Springsteen

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

A cute kiddo standing with a plant experiment. There are four blocks in the table, with each block having one replicate of three treatments. Blocks are labeled and ivy pots are labeled with treatment and pot number with labels varying by color matching treatment. Treatments are randomized within blocks. Heck yeah. She’s doing it right for the science fair!

Kiddo’s first randomized controlled blocked design. Gotta start ‘em right.

More than a year ago researchers from @hifmb.de and @icbm-uol.bsky.social started to write about different perspectives on marine biodiversity change from natural and social science perspectives. This morphed into a review paper that was published online today link.springer.com/article/10.1... 🧪

Emerging climate impact on carbon sinks in a consolidated carbon budget | Nature Despite the adoption of the Paris Agreement ten years ago, fossil CO2 emissions continue to rise, pushing atmospheric CO2 levels to 423 ppm in 2024 and driving human-induced warming to 1.36°C, within years of breaching the 1.5°C limit 1,2. Accurate reporting of anthropogenic and natural CO2 sources and sinks is a prerequisite to tracking the effectiveness of climate policy and detecting carbon sink responses to climate change. Yet notable mismatches between reported emissions and sinks have so far prevented confident interpretation of their trends and drivers 1. Here, we present and integrate recent advances in observations and process understanding to address some long-standing issues in the global carbon budget estimates. We show that the magnitude of the natural land sink is substantially smaller than previously estimated, while net emissions from anthropogenic land-use change are revised upwards 1. The ocean sink is 15% larger than the land sink, consistent with new evidence from oceanic and atmospheric observations 3,4. Climate change reduces the efficiency of the sinks, particularly on land, contributing 8.3 ± 1.4 ppm to the atmospheric CO2 increase since 1960. The combined effects of climate change and deforestation turn Southeast Asian and large parts of South American tropical forests from CO2 sinks to sources. This underscores the need to halt deforestation and limit warming to prevent further loss of carbon stored on land. Improved confidence in assessments of CO2 sources and sinks is fundamental for effective climate policy.

A new Nature paper accompanying the Global Carbon Budget finds that the land and ocean sinks are 25% smaller and 7% smaller, respectively, than they would have been without the effects of climate change over 2015-24:

Question: Does anybody know of papers studying the connection between #yeast #biodiversity and #ecosystem #functioning?
Can coexisting yeast strains show complementarity and niche partitioning?

Fig. 3. Estimated mitigation potential from forestation varies with land availability assumptions. (A) Global and regional ecosystem carbon sequestration. BA19 (10), GR17 (8), and Qin24 (24) refer to respective assumptions of land potentially available for forestation. The “committed” assumption considers only national commitments, and “achievable” shows currently achievable land limited by availability defined in Qin24 (see materials and methods section M3). (B) The currently achievable mitigation potential varies among countries and income groups. Country-specific data are available in data S3 (24). Country codes and corresponding income groups can be found in table S6.

The achievable carbon uptake from planting trees is much lower than previous estimates, and even lower than many nations have committed to. New paper by Wang et al. in Science. www.science.org/doi/10.1126/... 🧪🌏🌳🌲🌐

Once again on the “achievements” of the most right wing government in the history of #Finland. Sigh.

To warn others to learn from our mistakes.

On the left, government projections of new jobs (blue) vs the reality (red); on the right, distribution of tax cuts by income decile.
