Although NOAA's page on atmospheric CO2 levels has vanished, you can still get this vital information from Ralph Keeling's team at the Scripps Institution of Oceanography, UC San Diego keelingcurve.ucsd.edu Please follow bsky.app/profile/keel... for updates and share Don't let science be hidden
A graph of atmospheric carbon dioxide concentrations at the Mauna Loa observatory, Hawaii, from 1958 to 4th February 2025. It shows carbon dioxide levels rising at an accelerating rate over the decades. This is known to be due to emissions of carbon dioxide from human activity, mainly fossil fuel burning but also deforestation. The first CO2 concentration value in March 1958 was 315 parts per million (ppm). The latest daily value is 426 ppm. The graph also shows a seasonal cycle of a few ppm within each year, which is known to be linked to the growing season in the northern hemisphere causing a temporary uptake of carbon in spring and summer and release in autumn. The graph is produced routinely by the Scripps Institution of Oceanography, UC San Diego.

Are you interested in large scale biodiversity patterns, conservation, ecology, ecosystem functions... So you should consider connecting with researchers within the Global Ecology starter pack (DM @global-ecology.bsky.social if you want to be added).

Using long term data from the Great Barrier Reef, a study in Nature Communications finds that shifts in coral composition correlate more strongly with reef fish diversity changes than fluctuations in coral cover. go.nature.com/4g7mKIm 🧪
This is figure 1, which shows reef fish species richness (α diversity) across time and latitude.

Still hope for coral reefs. Using 28-years of data in Seychelles, we find reefs recovering 4-5 years faster from the 2016 bleaching event, than they did after 1998. Also, a reef that had regime-shifted to macroalgae for over 15 years, is recovering to coral. onlinelibrary.wiley.com/doi/10.1111/...

Assessing coral reefs across the inner Seychelles islands, using a 28-year dataset, we document faster coral recovery from the 2016 than the 1998 marine heatwave events. Further, a reef that had regi....

For anyone newly interested in #behaviour and/or #macroecology since #BES2024, check out our paper that outlines #Macrobehaviour - a merger of the two to address challenges of rapid env change www.cell.com/trends/ecolo... Let's grow this community!
cell.com
Macrobehaviour: behavioural variation across space, time, and taxa
We explore how integrating behavioural ecology and macroecology can provide fundamental new insight into both fields, with particular relevance for understanding ecological responses to rapid environmental change. We outline the field of macrobehaviour, which aims to unite these disciplines explicitly, and highlight examples of research in this space. Macrobehaviour can be envisaged as a spectrum, where behavioural ecologists and macroecologists use new data and borrow tools and approaches from one another. At the heart of this spectrum, interdisciplinary research considers how selection in the context of large-scale factors can lead to systematic patterns in behavioural variation across space, time, and taxa, and in turn, influence macroecological patterns and processes. Macrobehaviour has the potential to enhance forecasts of future biodiversity change.
