World’s cloud forests ‘headed for destruction’

28 Mar

Writing in the journal Nature Climate Change an international scientific team has warned of the near-total loss of one of the world’s most delicate ecosystems, the Mexican cloud forest, along with 70 per cent of its plant and animal species, as a result of human pressures.

“Cloud forests occur only at certain high altitudes and their species are exceptionally vulnerable to the loss of the cool, moist environment that sustains them,” explains lead author Rocio Ponce-Reyes of Australia’s ARC Centre of Excellence for Environmental Decisions (CEED) and The University of Queensland.

“Habitat loss and degradation by human encroachment are the main threats to cloud forests around the world at the moment,” says Ms Ponce-Reyes.

“However, given the narrow environmental tolerance of cloud forests, the fear is that human-induced climate change could constitute an even greater peril in the near future.”

Forests are dying all over the world in one way or another. The effects could be disastrous.

Scientists say the future habitability of the Earth might well depend on the answer. For, while a majority of the world’s people now live in cities, they depend more than ever on forests, in a way that few of them understand.

Scientists have figured out — with the precise numbers deduced only recently — that forests have been absorbing more than a quarter of the carbon dioxide that people are putting into the air by burning fossil fuels and other activities. It is an amount so large that trees are effectively absorbing the emissions from all the world’s cars and trucks.

Without that disposal service, the level of carbon dioxide in the atmosphere would be rising faster. The gas traps heat from the sun, and human emissions are causing the planet to warm.
