Late summer in Katmai National Park.
During this time in early September, the tundra comes alive with a psychedelic wave of color. Everywhere you look you are surrounded by undulating layers of reds, oranges, yellow and green.

Most of these small plants grow berries, and in this shot there are over 10 species of berries that I can see.

We were camped here for a week and got absolutely pounded by rain and wind, and on our last day it opened up and we went exploring. Hiking up that snow kissed peak in the background and then we dropped down through miles of tundra to a double waterfall that we had spotted on our flight in. Such a beautiful place, can’t wait to go back.

World's oldest #juniper shrub discovered in #Finland—rings suggest it's 1,647 years old phys.org/news/2025-02-world-ol

Common juniper, the oldest nonclonal woody species across the #tundra biome and the European continent esajournals.onlinelibrary.wile

"the juniper started its growth at #Utsjoki in 260 and died in 1906... It is the oldest shrub in the world and the oldest woody plant in Europe dated by annual rings... #junipers allow scientists to study #climate variations, exceptional #weather events etc."

Ich stimme dem zu, möchte jedoch noch Folgendes ergänzen: es ist in den letzten Jahren ein sehr starker Fokus auf #CO2 als #Treibhausgas erfolgt.
Bislang lagen fast alle #Klimaprognosen unter der Realität. Könnte es vielleicht sein, dass das #Treibhausgas #Methan noch zu wenig beachtet wird?

Insbesondere durch das Auftauen des #Permafrosts in der #Tundra dürfte das Problem noch schlimmer werden:

"Permafrost soils store vast amounts...

Groundwater in the Arctic is delivering more carbon into the ocean than was previously known

A relatively small amount of #groundwater trickling through #Alaska's #tundra is releasing huge quantities of #carbon into the #ocean, where it can contribute to #ClimateChange, according to new research out of The University of Texas at Austin.
As the tundra continues to thaw and the flow of submarine groundwater ratchets up, Demir said that the outflow of carbon from shore to sea could effectively make ocean surface waters a carbon source to the #atmosphere. The #CO2 released via groundwater could also contribute to ocean #acidification.
"The #Arctic coast is changing in front of our eyes," said Bayani Cardenas, a co-author of this study and professor at the Jackson School's Department of Earth and Planetary Sciences. "As #permafrost thaws, it turns into coastal and submarine #aquifers. Even without this thawing, our studies are among the first to directly show the existence of such aquifers."
