Your 'moment of doom' for Jan. 21, 2025~ What happens in the Arctic.

"In the permafrost, most of the soils have been entirely frozen throughout the full year. But now the temperatures are warmer, there’s more organic matter available for decomposition, and carbon gets released into the atmosphere."

Without genuine engagement the longevity of initiatives is less likely.
It is quite remarkable to read proposals where scientists say they are going to develop all these wonderful new insights for conservation, sustainability, etc

But then say they will disseminate their findings to stakeholders at the end of the project

Rather than engage with them at the start

November 2024 sea ice thickness was below average across most of the #Arctic Ocean compared to the 1981-2010 average, especially north of Greenland, the Canadian Arctic Archipelago, and Svalbard (right; red shading).

Too often ‘impact’ is co-opted to describe how policy makers use our research

True impact for ecologists is to contribute to meaningful nature recovery

Sadly, those 2 aims are not the same

This graphic gives the 12-month running average for Mauna Loa CO₂ since 1959, with a quadratic trendline (in red).

An R² of 0.9995 is overwhelming evidence that atmospheric CO₂ growth is accelerating. And at present, CO₂ is above the trendline!

Confirmation bias - when examples of colonisation of trees on abandoned land are used to argue for the ubiquity of natural regeneration

but examples of areas remaining largely treeless through dispersal limitation, soil conditions, etc, are ignored

For those who still think that planting trees is a solution to mitigate CO2 emissions, please take note! Forest offset programs can also burn!

Absolutely spot on!
To me, this is such an important message, as so many ecologists seem (paradoxically) to lose their connection with nature as they get promoted up the career ladder. Time spent in nature, especially if together with the next generation of ecologists, is time very well spent.
