North American Forests Not a Climate Change Remedy
2016-07-24 12:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: North American forests will not fight climate change by absorbing carbon dioxide at levels once hoped for because the trees may not grow big enough, a study said. The new research challenges previous studies that said trees could grow larger due to higher temperatures brought on by global warming, said the authors of the study published in the journal Ecology Letters. Typically, up to a third of carbon-dioxide emissions from human activity, such as automobile driving or steel production, is...

Tree ring warning: Forests may not be able to save us
2016-07-22 18:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Futurity: Forests take up 25 to 30 percent of human-caused emissions of carbon dioxide--a strong greenhouse gas--and therefore are considered to play a crucial role in mitigating the speed and magnitude of climate change. However, a new study that combines future climate model projections; historic tree-ring records across the entire continent of North America; and how the growth rates of trees may respond to a higher concentration of carbon dioxide in the atmosphere shows that the mitigation effect of...

Tropical forests overexploited by unsustainable logging
2016-07-14 03:32:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Widely hailed as a renewable natural resource, tropical timber from old-growth tropical forests is selectively logged worldwide at an unprecedented scale. But research from the University of East Anglia reveals that these sources of timber are far from sustainable or entirely environmentally friendly. A study published in PLOS ONE reveals that once prime tropical hardwoods -- such as Brazilian cedars, ipe (Brazilian walnut), and rosewood -- have been logged, they do not grow back to commercial...

Disturbing forests damages natural diversity
2016-07-11 12:38:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: Toucans and other birds helped to reveal the impact of forest damage. Ensuring tropical forests are protected from human intrusion is vital if they are to preserve the many creatures that inhabit them, researchers say. It is not enough just to conserve forest. It may be just as important not to disturb any of it. New research suggests that selective logging, hunting and other kinds of damage can do serious harm to the biodiversity within the remaining forest. Jos Barlow, an ecologist at the...
