One of the "scientists' warnings" papers (The 2025 state of the climate report: a planet on the brink )

 This is another one of the "scientists' warnings" papers (The 2025 state of the climate report: a planet on the brink ).

From the abstract:

" We are hurtling toward climate chaos. The planet's vital signs are flashing red. The consequences of human-driven alterations of the climate are no longer future threats but are here now. This unfolding emergency stems from failed foresight, political inaction, unsustainable economic systems, and misinformation. Almost every corner of the biosphere is reeling from intensifying heat, storms, floods, droughts, or fires. The window to prevent the worst outcomes is rapidly closing. In early 2025, the World Meteorological Organization reported that 2024 was the hottest year on record (WMO 2025a). This was likely hotter than the peak of the last interglacial, roughly 125,000 years ago (Gulev et al. 2021, Kaufman and McKay 2022). Rising levels of greenhouse gases remain the driving force behind this escalation. These recent developments emphasize the extreme insufficiency of global efforts to reduce greenhouse gas emissions and mark the beginning of a grim new chapter for life on Earth."

 

a week in Gr Smoky Mts NP

 

My family spent a week hiking in Great Smoky Mountains National Park. 

 

 

Along with my search for birds, we all were in awe of many "old-growth" trees in the forests of the park. One particularly-noteworthy area was the Cosby Creek trail, with many small streams, and many large trees,

 At high elevations in the national park, Dark-eyed Juncos, Common Ravens, and Black-capped Chickadees are found (in the range where Carolina Chickadees are espected, but at lower elevations).

 

These Bluets were seen there: 

 

Here, along the Oconaluftee River, we saw 3 elk. 

 

 

Because I live in southeastern WI, many songbirds encountered in GSMNP are very uncommon to slightly "rare" where I live:

Blue Grosbeak

Summer Tanager

Worm-eating Warbler 

Black Vulture,

and most uncommon of all,

Swainson's Warbler. 

 

 

 

Biodiversity resilience in a tropical rainforest

Abstract

The UN Decade on Ecosystem Restoration aims to stop biodiversity losses¹. Approximately 60% of tropical forests have already been lost or severely degraded², making restoration essential to achieve conservation goals. Recovery trajectories of trees have been studied intensively^3,4, but a comprehensive understanding of biodiversity recovery is lacking. Here we analyse recovery trajectories across trophic levels including 16 taxonomic groups from three kingdoms in a lowland tropical forest by investigating resistance to perturbation, recovery times and return rates to old-growth forest conditions. Abundance and diversity regained more than 90% and composition approximately 75% similarity to old-growth forests within 30 years, but full recovery takes several decades. Mobile animal communities acting as seed dispersers or pollinators had high resistance levels and recovered faster than trees or tree seedlings. Return rates contributed 1–2.5 times more than resistance to the recovery times of species composition. Taxon-specific recovery times could not be explained by simple mechanisms (life-history strategies, trophic level or mobility). We show the enormous potential of protecting naturally recovering secondary forests to stop and reverse biodiversity losses.
