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.

Climate Change And Trees That Disperse Seeds By Wind

According to the research, trees which disperse their seeds by wind, such as pines and maples, will be unable to spread at a pace that can cope with expected climate changes

Climate Change A Matter Of Belief More Than Facts

Over the past few months, polls show that fewer Americans say they believe humans are making the planet dangerously warmer, despite a raft of scientific reports that say otherwise.
This puzzles many climate scientists

The Amazon Giveth As Well As Taketh Away

For years the Amazon forest has been helping slow down climate change… But relying on this subsidy from nature is extremely dangerous. If the Earth's carbon sinks slow or go into reverse, as our results show is possible, carbon dioxide levels will rise even faster.

Conservative Plants And Climate Change

Most southern hemisphere plants — except for weeds — will not be able to adapt to rapid climate change, a study of more than 11,000 species suggests.
