Biodiversity conservation has an evidence problem — it’s time to fix it
Globally, more than one million species are threatened with extinction, but often interventions intended to protect biodiversity are not rooted in robust research. The field has an opportunity to chan...

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...

Proposed NOAA budget zeros out ALL climate laboratories and cooperative institutions.

This appears to also end the US greenhouse gas sampling network, including at Mauna Loa, the oldest continuous carbon dioxide monitoring site on Earth.
