Climate Change Caused Widespread Tree Death In California
Here is another thing we have to worry about with global warming and the rise in temperature.
Can any science wiz explain this to me, but doesn't plants and trees do the whole conversion of carbon dioxide and oxygen thing so our ecology and world is balanced. I am pretty sure the carbon dioxide and oxygen does something else important in the world that is relevant to global warming and the weather. I don't remember too much of this as elementary science was a while ago. Anyways, this cannot be good news knowing trees are dying due to the climate change.
Warmer temperatures and longer dry spells have killed thousands of trees and shrubs in a Southern California mountain range, pushing the plants' habitat an average of 213 feet up the mountain over the past 30 years, a UC Irvine study has determined.
White fir and Jeffrey pine trees died at the lower altitudes of their growth range in the Santa Rosa Mountains, from 6,400 feet to as high as 7,200 feet in elevation, while California lilacs died between 4,000-4,800 feet. Almost all of the studied plants crept up the mountain a similar distance, countering the belief that slower-growing trees would move slower than faster-growing grasses and wildflowers.
This study is the first to show directly the impact of climate change on a mountainous ecosystem by physically studying the location of plants, and it shows what could occur globally if the Earth's temperature continues to rise.
