Zoals verwacht komt de Ministeriële commissie Economie en Natuurherstel niet met een oplossing voor de stikstofproblematiek. Het kabinet kiest ervoor om de natuur verder te laten verslechteren en ondernemers nog eens 10 jaar in onzekerheid te laten zitten. nos.nl/artikel/2564...

Kabinet wil uitstoot stikstof in 2035 halveren

Vrijdag komt het kabinet met de contouren van het nieuwe stikstofbeleid. Leidend daarbij wordt de uitstoot van stikstof bij de bron, dus bij boeren en bedrijven zelf.

→ Early snowmelt = earlier egg-laying, but only 2 waterfowl arrived earlier.
→ Over time, most arrived earlier—regardless of snowmelt or laying.
→ Why? Faster migration: shorter stopovers = earlier arrival.

Migratory Birds Advance Spring Arrival and Egg‐Laying in the Arctic, Mostly by Travelling Faster

A warming climate is affecting the phenology of life on earth, including when birds migrate and start breeding. We show that earlier arrival is a general pattern also for birds travelling to the Arct...

Interestingly, models also indicated an increased young survival following an El Niño winter. We suggest this time-lagged effect reflects downstream propagation of environmental conditions, particularly food availability, or a potential carry-over effect of El Niño conditions... 2/3

Peatlands occupy just 3% of all land but contain more carbon than all of the world’s forests.
Often overlooked: typically flat, wet, often inaccessible, not always picturesque & all the carbon they hold is hiding below the surface.
80% of the UK bogs are degraded by draining, overgrazing, burning.

Sobering. When I talk to people about long-term bird population declines in N America, I mention that the main cause is habitat loss, not climate change - yet. But new research shows that climate change is causing bird declines even in otherwise pristine places. www.theguardian.com/environment/...

In the most untouched, pristine parts of the Amazon, birds are dying. Scientists may finally know why

Populations have been falling for decades, even in tracts of forest undamaged by humans. Experts have spent two decades trying to understand what is going on
