A New Way To "Light Up:" Tobacco As Biofuel!

The leaves would then be crushed, and the fuel extracted and separated. The scientists estimate that about 1000 acres of tobacco could yield more than one million gallons of fuel.

Palm Biodiesel As Polluting As Oil

So palm oil and soy bean biodiesel is just a touch less polluting than fuel from tar sands: that's pretty damning. Maize and sugar do better than crude oil but still cause significant carbon emissions.

Climate Change Driving Elk To Decimate Mountain Forests

The densities of seasonal woodsy plants, including aspen and maple trees, in the northern Arizona mountains have steadily declined over the last two decades… this decline is primarily the result of one of two things: decreased soil water or increased exposure to hungry elk.

Ants On Strike Against Global Warming

If the temperature increases by just a half a degree Celsius, the most important seed-dispersing ants basically shut down. They do not go out and forage and do the things they normally do.

300 Year Old Plants Predict Our Climate Future

A strong relationship between mountain plum pine growth and snow cover means we may be able to estimate annual snow conditions well before European settlement, which is important because it will tell us whether the current declining snow conditions have precedent.

How A Fungus Destroyed Ancient Forests And Might Do It Again

The demise of the world's forests some 250 million years ago likely was accelerated by aggressive tree-killing fungi triggered by global climate change

Can Forests Migrate With Climate Change?

Predictions about where trees will grow in the future have been based primarily on climate models… but there are other factors, like the soil environment, that may limit whether a tree species will be able to move into a new area.

When An Iconic Centuries-Old Plant Isn’t Welcome Anymore

Over the millennia, the Joshua tree (Yucca brevifolia) has evolved to thrive in the dry and hot Southwestern desert conditions and barren soils that a less specialized plant species could not tolerate. Now, two recent papers detailing future climate scenarios for Joshua Tree National Park and the Joshua tree's natural range are projecting tough times for this venerable Southwest icon.

Can Forest Plantings Control Global Warming?

Foresting all or half the world's cropland reduced global temperatures in 2100 by 0.45 °C and 0.25 °C respectively.
