Climate change and speleothems of Greenland

The research team of Gina Moseley, the geologist from the University of Innsbruck, investigated f 12-centimetre-thick sample of a flowstone from a cave in the northeast of Greenland. One of the features of this kind of cave deposits is that in order for it to form the climate in the corresponding area must be much wormer and wetter than today's Greenland. The period between about 588,000 to 549,000 years before present to which the formation of the flowstone corresponds is considered to be cooler on the global scale compared to the present. This suggests that at that time the Arctic was warmer in contrast to other areas of the time.

Strange craters emerging in Siberia due to permafrost melting

The are believed to be appearing due to explosions of methane gas that is building in the underground layer of ice. The exact details of the process are yet to be discovered but it is already clear that permafrost is a huge natural reservoir of this gas and that the effect of global warming will lead to farther increase of it release to the atmosphere.

The recent and ongoing bushfires have severely damaged many cave areas across Australia. Your donation to the Australian Speleological Federation will help restore cave ecosystems. Donate here: http://www.gofundme.com/f/cave-landscape-bushfire-rehabilitation-appeal

Known impacted cave regions:
WA: Yanchep, North of Perth; Kempsey -Willi Willi Maternity Bat Cave, rainforest areas and more; NSW: Bungonia; Wombeyan; Yarrangobilly; Jenolan area VIC: Buchan area, Buchan Caves Reserve, East Buchan, Caves Potholes Reserve, the Basin, New Guinea Ridge; Budj Bim (Mt Eccles National Park) World Heritage Area (cultural site); SA: Kangaroo Island, Kelly Hill Caves Reserve and many cave components of Flinders Chase.

These are only some of the areas known to be impacted – we anticipate many more caves have been or will be affected.


Funds raised will go directly toward:
- Projects aimed at cleaning and restoring caves and karst areas
- Immediate on ground works to cave affected areas
- Cave entrance stabilisation, fencing and stairway replacements (that are not covered by insurance)
- Rehabilitating vegetation in cave landscapes
- Rehabilitating of critical habitats for bat and cave cricket populations
- Research projects to assess long term bushfire impact on fauna and cave environments
- Bat population surveys post-fire
- Replacement of entrance identification cave tags where needed.

The Australian Speleological Federation (ASF) is an Environmental Organisation, with the primary objective is to protect the cave and karst environments of Australia.

As the national body in Australia ASF represents 22 caving clubs with over 800 members and represents Australia on the International Union of Speleology. The ASF is registered as an Environmental Organisation by the Department of Environment and Energy, Canberra to receive tax deductible donations to use in pursuit of its environmental objectives to protect caves and karst environments in Australia via its Karst Conservation Fund.

All donations over $2 are tax deductible!
