Federal protection sought for Joshua trees

2015-10-01 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

LA Times: Drought, more frequent wildfires and rising temperatures due to climate change are upsetting the delicate balance between life and death conditions for Joshua Tree National Parks peculiar namesake plant. Many Joshua trees in the region have not reproduced in decades. If warmer, drier conditions continue, scientific modeling suggests the symbols of Californias deserts will lose 90% of their range in the 800,000-acre park and surrounding terrain by the end of the century. As part of an effort to...

Broadleaf trees show reduced sensitivity to global warming

2015-09-30 17:02:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: The sensitivity of leaf unfolding phenology to climate warming has significantly declined since 1980s, according to a study recently published in the journal Nature by an international collaboration of scientists. Earlier spring leaf unfolding is a frequently observed response of plants to climate warming. Many deciduous tree species require cold temperatures, in other words 'chilling', for dormancy release, and the warming-related reductions in chilling may counteract the advance of leaf unfolding...

Government firefighting policies, climate change bad for trees in West

2015-09-27 08:01:00| Climate Ark Climate Change & Global Warming Newsfeed

Columbia Dispatch: The hills are beautiful, a rolling, green landscape of grasses and shrubs under a late-summer sky. But it is starkly different from what was in this part of northwestern New Mexico before: vast forests of ponderosa pine. The repeated blazes that devastated the trees were caused by simple things: an improperly extinguished campfire in 1996, a tree falling on a power line in 2011. What happened after the fire, however -- or, more accurately, what has not happened -- was a departure from the normal...

Climate Change and Tree Growth: New Trees Cant Handle As Much Carbon As We Thought, Study Shows

2015-09-25 19:03:00| Climate Ark Climate Change & Global Warming Newsfeed

Nature World: Photosynthesis is driven by atmospheric carbon dioxide, so trees are often planted to capture and store the increasing carbon emissions we face today. It turns out that our reliance on them may be overestimated, according to a recent study. To better understand future tree growth related to increased carbon emissions, researchers from the University of Illinois at Urbana-Champaign and the University of Bristol in the United Kingdom modeled future land cover and use. They discovered that forests...
